Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material having a skin-like uneven surface pattern of natural sedimentary rock which is rich in depth and depth, and a method for producing the same, for decoration of interior and exterior wall surfaces or floor surfaces of buildings. .

[0002]

2. Description of the Related Art A synthetic resin emulsion and an aggregate such as a marble powder or a colored aggregate such as colored silica sand or a colored aggregate such as colored porcelain powder are used as a spray material, and a woven cloth or other suitable relatively coarse synthetic fiber fabric is used. A decorative material coated with a suitable method such as spraying on a suitable solid base material to give a natural stone-like pattern is used as a sheet for finishing the interior or exterior wall surface or floor surface of a building. ing. (JP-A-4-7
6151, JP-A-3-279561).

Sedimentary rocks such as sandstone, slate and mudstone are rocks formed by debris produced by mechanical weathering of rocks, carried and accumulated by running water, wind, glaciers, etc., and generally have a stratified structure. Have Therefore, when rock is broken in the layer direction, a so-called split skin-like uneven pattern having unique unevenness appears on the surface generated by breaking the rock. That is, a rock layer appears with a convex portion, and in the concave portion, for example, a layer below the convex portion is exposed on the surface. And as a result of various studies by the present inventor,
Due to the difference in the layers between the concave and convex portions, a subtle difference in color tone,
For example, a slight difference in lightness, a difference in saturation, a difference in hue, or a difference of two or more of these may occur, and a deep and natural skin-like uneven pattern peculiar to natural sedimentary rock appears. I found out. Therefore, these natural sedimentary rocks having a deep, uneven skin pattern have been used as wall materials and floor materials for high-grade buildings.

However, natural sedimentary rocks are expensive, very heavy and extremely costly to transport, and are heavy and therefore difficult to work in high places, for example. Depending on the impact, parts such as corners may be chipped due to impact, such as careless impact when unloading a work site from a truck, etc. However, there are problems such as being difficult to supply and that it is difficult to process it into a curved surface with a split skin uneven pattern.

On the other hand, a spray material containing the above-mentioned synthetic resin emulsion and an appropriate aggregate such as marble powder, silica sand, ceramic powder or colored silica sand, colored ceramic powder, etc. is sprayed onto a cloth cloth or other suitable cloth-like sheet base material. A decorative material that is applied by a proper method, or obtained by molding and having a natural stone-like pattern is relatively inexpensive compared to natural rock, it is lighter in weight and advantageous in terms of transportation cost. A variety of products can be stably produced over a long period of time, and depending on the type of synthetic resin used, in the case of the most commonly used acrylic resin, generally thermoplastic resin or its cross-linked product, etc. Is relatively flexible, so make a flat sheet with an appropriate rock pattern,
It is possible to apply this to a curved surface while bending it along the curved surface of the installation surface, and when using a synthetic resin that makes the molded product hard, a method of spraying or applying to a base material having the desired curved surface or Since it is possible to mold the mold with a curved surface, it is possible to perform curved surface processing relatively easily, and because it is relatively light and easy to handle during construction, construction work can be performed even in high places. In recent years, it has been frequently used as a sheet for finishing the surface of a building such as for decorating the interior / exterior wall surface or floor surface of a building.

[0006] Then, using a synthetic resin emulsion or solution and a coating material containing an appropriate aggregate such as marble powder, silica sand, ceramic powder or colored silica sand, colored ceramic powder, sandstone and other sedimentary rock split skin-like uneven patterns are formed. The present inventor also conducted various studies on the decorative material having the same, and used a silicone rubber for patterning on the cracked skin of natural sedimentary rock to mold a skin-like unevenness inversion relief pattern, or another suitable method for natural cracking. Taking a relief pattern with skin unevenness inversion, using this as a mold, spraying or applying the coating material to this mold, and if necessary, an underlayer for further increasing the thickness on the back side. It is possible to spray it, apply it, or stack cloth-like base material sheets such as garment cloth made of synthetic fiber, dry and solidify it, and remove it from the mold to give a rough texture pattern on the deposited rock. Was Tsu.

[0007]

However, although these molded products have an uneven pattern of sedimentary rock split skin, they are slightly different from those of natural sedimentary rock, and are unique to the split surface of natural sedimentary rock. There was a problem in that it was only possible to obtain decoration materials with a slightly low added value, which were not sufficient in depth and solidity. According to the study by the present inventor, it was found that this decorative material gives a monotonous feeling because the concave portion and the convex portion have the same color tone. In order to solve this drawback, the present inventor has made similar to or similar to the split skin of natural sedimentary rock by changing the color tone of the concave portion and the convex portion, that is, at least one of saturation, lightness and hue. The present invention has been accomplished by discovering a decorative material having a skin-like unevenness pattern of a sedimentary rock having a depth and solidity and a method for producing the same.

The present invention has a split skin-like uneven three-dimensional pattern similar to the split skin surface of natural sedimentary rock, is lighter in weight and easier to handle than natural sedimentary rock, and may cause corners etc. due to a slight impact during transportation or work.

[0045]

EXAMPLES A synthetic resin matrix of one component constituting a decorative material having a skin-like uneven surface pattern of a sedimentary rock of the present invention is a synthetic resin of an upper layer, a lower layer, or an underlayer used for the purpose of increasing the thickness as necessary. In any of the components, a synthetic resin emulsion or a synthetic resin solution is usually used as a raw material, and various synthetic resin emulsions or solutions conventionally used in the production of a decorative material having a natural stone pattern can be used. . Synthetic resin emulsions are preferably used from the viewpoint that it is not necessary to consider the recovery of organic solvents and environmental problems. Especially weather resistance,
A synthetic resin emulsion satisfying alkali resistance, water resistance, adhesiveness, flexibility, water absorption resistance, etc. is preferable. Specific examples include acrylic resin emulsions (acrylic-styrene resin emulsion, acrylic-urethane resin). Emulsion, acrylic-silicone resin emulsion, acrylic-fluorine resin emulsion),
Examples thereof include vinyl acetate-based resin emulsions such as ethylene-vinyl acetate resin, vinyl chloride-based resin emulsions and urethane-based resin emulsions. The resin matrix after drying of any of these resins has appropriate flexibility, and can be applied to a curved surface. Of these, acrylic resin emulsions are particularly superior in terms of weather resistance, and thus are preferred because they have long-term durability when used as a sheet for finishing building surfaces such as interior and exterior wall surfaces or floor surfaces of buildings.

As the aggregate, various known aggregates used in the production of the decorative material having such a natural stone pattern can be used. Marble powder, granite powder, silica sand and other natural stone powder, ceramics Fine powder of natural stone, such as powder, or artificial coloring of these, for example, so-called colored aggregate such as colored fired silica sand or colored ceramic powder,
Ceramic fine particles, or at least one of these colored materials
Inorganic materials typified by seed aggregates are preferably used. These aggregates are preferably used because they are more durable and less expensive than aggregates made of an organic material such as plastic, without fear of fading or discoloration.

As for the size of the aggregate, it is preferable to mainly use the aggregate having a size of 12 to 200 mesh. It is to be noted that a desired color tone or wind can be obtained by appropriately combining one or two or more of artificially colored colored aggregates or particularly aggregates of the same color as the raw material that is not artificially colored. Can be adjusted.

If desired, a scale-like additive represented by mica, colored mica, synthetic resin colored flakes or the like may be added separately to give a unique texture. The scale-like additive is usually 200 mesh to 1 cm.
Those having a size of about ² are preferably used.

The mixing ratio of the aggregate and the synthetic resin matrix is such that the sedimentary rock has a texture of sandstone, slate, mudstone, or the like, or the texture of which is similar to that of the sedimentary rock. There is a slight difference in the first coating material that becomes the following or the second coating material that becomes the lower layer,
The proportion of the synthetic resin emulsion or solution in solid content is preferably about 5 to 20 parts by weight with respect to 100 parts by weight of the aggregate.

By adopting a preferred embodiment in this range, the synthetic resin component has a relatively small specific gravity as compared with the aggregate and the like, so that it occupies a considerable amount in volume, and the role of the aggregate as a binder. By doing so, it is possible to provide a decorative material having a sedimentary rock split skin-like uneven pattern having a durable strength while maintaining the texture of a natural sedimentary rock.

In order to adjust the color tone of the coating layer, one kind or two or more kinds of various aggregates having the original color tone of the raw material or so-called colored aggregates artificially colored as described above are appropriately mixed. It is achieved by

In the present invention, an aggregate for the first coating material and the second coating material so that a difference in color tone after drying of the first coating material and the second coating material forming the upper layer and the lower layer may occur. Adjust the composition of. It depends on the target color tone difference, but the type and amount of aggregate in the first coating material and the second coating material, the color, type and amount of the aggregate, such as the combination of two or more aggregates. It can be adjusted by a combination of increasing and decreasing the number of types of addition. The color tone difference is achieved, for example, by adjusting the first coating material and the second coating material so that at least one of hue, brightness, and saturation is different. And, preferably, the range of difference in lightness of the first coating material and the second coating material forming the upper layer and the lower layer after drying is 0.5 to 4 in Munsell value or the range of difference in saturation. Is similar to that of natural sedimentary rocks in that the Munsell value is in the range of 1 to 5, or both of them are satisfied, or the difference of hues is satisfied by satisfying both of these ranges. It is also preferable because it can provide profoundness and depth. It should be noted that comparing the color difference between the first coating material and the second coating material with the color tone after drying is sufficient in the normal case if the color tone is adjusted before drying, but for some, it is This is because the color tone before and after drying may be slightly different, so that it is preferable to compare the color tone after drying.

Since the Munsell value is published in various books such as chromatics and is well known, its explanation is omitted. For example, "Munsell Book of Color, NEIGHBORING HUESEDIT" (published by Munsell Color Company, Inc., Baltimore, MD, USA) (MUNSELL BOOK OF COLOR, NEIGHBORING HUESEDIT)
ION, MUNSELL COLOR COMPANY, Inc. BALTIMORE ・ MAR
YLAND USA) etc.

Further, as a base layer to be laminated further underneath the lower layer in order to increase the thickness of the entire decorative material as necessary, a base layer formed by similarly dispersing an aggregate in a synthetic resin emulsion or a solution. A coating material is used, and it is not necessary to consider the color tone of this underlayer, and any color tone may be used, but usually the same material as the second coating material used for the lower layer is often used. However, since it is a layer for giving thickness, it is not limited to this.

If necessary, the first coating material, the second coating material, or the coating material serving as the base layer may further include a filler, a film-forming aid, a thickener, a defoaming agent, a pH adjusting agent, and the like. In addition, water or an appropriate solvent may be added to reduce the viscosity.

For example, as the filler, calcium carbonate or the like, and as the thickener, for example, a methylcellulose-based one (for example, "High Metroze 90SH-30000",
Shin-Etsu Chemical Co., Ltd.), a film-forming aid such as butyl carbitol acetate, and an antifoaming agent such as "Nopcosanto NXZ" (manufactured by San Nopcosan Co., Ltd.).
For example, concentrated ammonia water is preferably used as the pH adjuster, but the pH adjuster is not limited thereto.

In the decorative material of the present invention, since the cloth-like sheet base material is laminated on the back side of the decorative material, the strength of the decorative material can be further increased, and therefore, the decorative material which is easier to handle can be provided. Although preferred, as the cloth-like sheet substrate,
For example, a cloth-like sheet base material used in the production of a decorative material such as a conventionally used surface finishing sheet for buildings of this type may be similarly used. Specifically, for example, a synthetic fiber woven fabric, more preferably, a synthetic fiber woven fabric having a relatively coarse mesh, for example, a gauze made of acrylic fiber or polyester fiber having no water absorption or having a small water absorption, or a woven fabric having a coarser fabric than that. It is preferable, and a gauze cloth made of acrylic fiber or polyester fiber is particularly preferable. A woven fabric having no water absorption or a small water absorption is preferable. A woven fabric having a large water absorption tends to expand due to moisture and tend to shrink during drying, and the product after drying may warp or deform. In the case of using a woven fabric having no or little water absorption, such a problem does not occur, which is preferable.

Further, the cloth-like sheet base material is preferable because it does not impair the flexibility in the case of a soft decorative material,
This is because the cloth is breathable, so that when the decorative material of the present invention is molded in a mold and dried, water and solvent can be easily evaporated from the side where the mold does not exist, that is, the back side. Further, as the cloth-like sheet base material other than the woven cloth, a knitted cloth, a non-woven cloth, or the like can be applied.

When laminating the cloth-like sheet base material on the back side as described above, the cloth-like sheet base material is usually applied after the second coating material for forming the lower layer is applied and before the surface is dried. A method of laminating, usually after laminating, pressing with an appropriate roller or the like and then drying, or the above-mentioned bottom for applying a thickness after applying the second coating material for forming the lower layer The coating material for the underlayer may be further applied, and the cloth-like sheet substrate may be laminated in the same manner as above before the surface is dried, or after the second coating material for forming the lower layer is applied. , The first cloth-like sheet base material is laminated before its surface is dried, and before these are dried, or after or in some cases, dried to remove the mold, and then the above-mentioned base layer coating material And, if necessary, the above-mentioned base layer coating Surface of the wood is a fabric-like sheet substrate may be employed a method and structure for laminated in the same manner as described above prior to drying. Then, particularly when the cloth-like sheet base material at the final stage is laminated, any one of the first coating material, the second coating material, the coating material for the underlayer, etc. is further formed thereon. It is also preferable that the materials are laminated and then sprayed or applied more thinly because the cloth-like sheet base material can be more firmly adhered thereto.

The mold having the sedimentary rock split skin textured unevenness relief relief pattern used in the production of the decorative material having the deposited rocky skin textured unevenness pattern of the present invention is not particularly limited, but a silicone rubber mold or polyester. A mold made of an appropriate plastic film such as a film is preferably used. For example, in the case of silicone rubber mold,
A commercially available silicon rubber for molding is applied directly to the target split rock of the sedimentary rock to harden it, and then the silicon rubber is peeled off from the split rock of the sedimentary rock to provide a relief pattern of the uneven texture of the sedimentary rock. The mold can be easily obtained. Also, in the case of a plastic film mold such as polyester film, by applying the normal mold making method, as a result, firstly the male and female metal molds with the uneven surface pattern of the natural sedimentary rock are obtained. By making a mold of a mold, heating the created metal male and female molds, sandwiching an appropriate plastic film such as polyester film between them and embossing with a mold to mold Thus, it is possible to easily obtain a mold having a relief pattern in which the sedimentary rock split skin texture is inverted.

The method for producing the decorative material having a sedimentary rock split skin textured uneven pattern of the present invention by using the mold having the inner surface having the sedimentary rock split skin textured uneven relief pattern as described above will be further described below with reference to the drawings. To do.

FIG. 1 is a process cross-sectional view showing a step of one method for producing a decorative material having a skin-like uneven surface pattern of a deposited rock according to the present invention. As shown in FIG. 1 (a), a mold 2 having the above-mentioned inverted relief pattern of skin-like unevenness of deposited rock is placed on an appropriate flat substrate stand 1 such as a veneer plate. Then Fig. 1
As shown in (b), the mold is coated with the first coating material 3 for forming an upper layer in which an appropriate aggregate is dispersed in a synthetic resin emulsion or solution. The coating means is not particularly limited, but a spray gun is usually used to coat the coating material 3.
Is generally sprayed onto the mold 2, or the coating material 3 is generally applied onto the mold 2 using a trowel. Although the coating amount is not particularly limited, it is usually about 1 to 1.5 kg / m ² .

Next, as shown in FIG. 1 (c), before the first coating material layer dries (usually immediately after the coating is preferable to within 30 minutes after the coating). At least one of the first coating materials applied on the part 4
Remove all or part. The removing means is not particularly limited, but a technique of scraping off using a rubber spatula or the like is usually used. By doing so, the first coating material 3 is left in the concave portion of the mold 2 having the relief pattern of inverted concavo-convex. If necessary, the first coating material 3 is dried.

Next, as shown in FIG. 1D, for forming a lower layer having a color tone different from that of the first coating material and dispersing an appropriate aggregate in a synthetic resin emulsion or solution. The second coating material 5 is applied. As the coating means, the same means as the coating means for the first coating material can be used. Although the coating amount is not particularly limited, it is usually about 2.5 to 3 kg / m ² .

Next, if necessary, as shown in FIG. 1 (e), the cloth-like sheet before the surface of the second coating material is dried (usually preferably immediately after the coating and within 30 minutes after the coating). The base material 6 is laminated and pressed from above with a trowel or roller so that it is firmly laminated on the second coating material layer. After the cloth-like sheet base material 6 is laminated, in order to further secure the adhesiveness, a thin first coating material,
A suitable coating material such as the second coating material or the above-mentioned base layer coating material may be sprayed. This point is the same in the other modes, and the description in the other modes takes a long time. Therefore, in the other modes, the description is omitted.

Then, as shown in FIG. 1 (f), the mold is removed when the whole is dried, and the decorative material of one embodiment of the present invention can be obtained. That is, the bone is contained in a synthetic resin matrix composed of a lower layer in which an aggregate is dispersed in a synthetic resin matrix composed of the second coating material layer 5 and the first coating material layer 3 partially covering the surface of the lower layer. Since the upper layer and the lower layer are made up of dispersed materials, the upper layer and the lower layer have different color tones, so that the lower layer having a different hue partially appears in the concave portion 7 has a natural sedimentary rock-like appearance A decorative material is obtained. Since this decoration material is lighter than natural sedimentary rock and is not brittle like natural sedimentary rock, it is less likely to be dropped during work or chipped even if some shock is applied due to carelessness during transportation. It is easy, and work in high places becomes easier. Next, FIG. 2 shows a schematic cross-sectional view of a decorative material having a skin rock unevenness pattern according to another embodiment of the present invention. The main difference between the decorative material shown in FIG. 2 and the decorative material shown in FIG. 1 (f) is that the back surface of the lower layer made of the second coating material 5 has an underlayer 11 for further thickening. Further, the cloth-like sheet base material 12 is laminated on the back surface side of the base layer 11.

In the decorative material of this embodiment, after the step shown in FIG. 1D, the second coating material 5 is dried on the second coating material 5 if necessary, and further appropriately. The underlayer 11 composed of the synthetic resin emulsion or solution containing the aggregate of 1. is applied, and before the surface is dried (usually immediately after application to after application 3
It is preferably within 0 minutes. ) It can be easily manufactured by stacking the cloth-like sheet base materials 12, pressing them with a trowel or a roller from above and drying them, and then removing the mold.

In the above manufacturing method, the means for applying the underlayer 11 may be the same as the means for applying the first coating material or the means for applying the second coating material. The coating amount is not particularly limited, but usually 2.5 to 3 kg / m ²
It is a degree. In this aspect, the time for applying the underlayer 11 may be before or after drying the second coating material as long as it is after coating the second coating material. You may apply after removing a mold after drying a 2nd coating material. However, the present invention is not limited to this aspect, and in any of the aspects, when the first coating material layer and the second coating material layer or the base layer are applied, the previously applied layer has a low viscosity and is dried before drying. When the coating material is applied, it is mixed with the previously applied layer and changes in color tone and the like are unfavorable.If it is not preferable, dry the previously applied layer at least to the extent that no mixing occurs. It is preferable that the coating material for the next layer is applied after that.

Next, FIG. 3 shows a schematic cross-sectional view of a decorative material having a skin-like uneven texture pattern of deposited rock according to still another embodiment of the present invention. The main difference between the decorative material shown in FIG. 3 and the decorative material of FIG. 2 is that instead of the cloth-like sheet base material 12 of FIG. 2, a cloth-like material is formed between the lower layer of the second coating material 5 and the base layer 11. The point is that the sheet base material 6 is provided. By doing this,
It is possible to obtain a decorative material having a large thickness and an improved strength as shown in FIG. In this embodiment, the base layer 11 may be applied after the cloth-like sheet substrate 6 is laminated on the back side of the second coating material 5, or before the second coating material is dried. It may be applied after drying, or it may take some time depending on the case, but it is also possible to apply after removing the mold after drying the first and second coating materials. As the laminating means for the cloth-like sheet base material 6, the same method as described in the step of FIG.

Next, FIG. 4 shows a schematic cross-sectional view of a decorative material having a skin-like uneven texture pattern of deposited rock according to still another embodiment of the present invention. The decorative material shown in FIG. 4 is mainly different from the decorative material of FIG. 2 in that a cloth-like sheet base material 6 is further provided between the lower layer made of the second coating material 5 and the base layer 11. In this embodiment, the cloth-like sheet base material has two layers 6 and 12. By doing so, the strength can be further improved. In this embodiment, the base layer 11 may be applied after the second sheet material 6 is laminated on the back side of the second sheet material 5 before or after the second sheet material is dried. It may be applied afterwards, but depending on the case, it may take some time and labor, but it may be applied after removing the mold after drying the first and second coating materials. As the laminating means for the cloth-like sheet base material 6, the same method as described in the step of FIG. The laminating means for the cloth-like sheet base material 12 applies the undercoat layer 11 and laminates the cloth-like sheet base material 12 before the surface is dried (usually preferably immediately after application to within 30 minutes after application). A method similar to that described above, in which it is pressed from above with a trowel or roller, can be employed.
