Abstract

PURPOSE:To shorten the time and labor required for manufacturing decorative concrete slab by a method wherein decorative sheet, on the rear surface of which adhesive having adhesion to concrete is applied, is laid with the surface coated with the adhesive facing upwards and, after that, concrete is cast into a concrete form placed on the decorative sheet. CONSTITUTION:As decorative sheet 3, vinylon non-woven fabric, which contains glass fiber as fibrous sheet 31 and the basis weight of which is 50g/m<2>, is used. One side of the sheet 3 is coated with acrylic emulsion so as to produce plastic layer 32 and, after that, printed with pattern in weatherable ink and then coated with fluoroplastic paint so as to produce protective layer 34 having a thickness of 10mum. The other side of the decorative sheet 3 is coated with adhesive 2. The sheet 3 is laid on the floor width its surface coated with adhesive facing upwards and, after that, a wooden form 4 is placed on the sheet. In succession, mortar, which consists of 35wt.% of portland cement, 54wt.% of rever sand and 11wt.% of water, is cast in the form 14 and left as is. After the hardening of the mortar 1, the form 4 is removed so as to obtain a decorative concrete slab 1A.

[Industrial Field of Application] The present invention relates to a method for producing a decorative concrete board, particularly a concrete board with a pattern. [Prior Art] To decorate the inside and outside of concrete walls of buildings, spray painting with emulsion paints is often performed.
Spray painting has the drawbacks of creating mist, which creates a poor working environment, tends to cause uneven coating near the scaffolding, and requires a long time for the paint film to cure. In addition, spray painting
It is difficult to create interiors and exteriors with beautiful designs because patterns cannot be easily applied. Therefore, instead of spraying, painted concrete boards with a decorative sheet, especially a decorative sheet with a pattern, pasted on the surface are increasingly being used. Generally, concrete boards with patterns are manufactured by pasting a decorative sheet onto the surface of a pre-formed concrete board using an adhesive. However, such a manufacturing method is not efficient and is not fully satisfactory in terms of the smoothness of the surface of the decorative concrete board, the adhesion between the decorative sheet and the concrete, and its durability.

An object of the present invention is to provide a method for efficiently producing a decorative concrete board, particularly a painted concrete board, which has a smooth surface and good adhesion to a decorative sheet. [Means for Solving the Problems] As shown in FIG. 1, the method for manufacturing a decorative concrete board of the present invention uses an adhesive (
Lay the decorative sheet (3) with 2) applied to the inside surface with the adhesive side facing up, place the formwork (4) on top of it, and spread the mortar (
1) is poured, cured, and then the formwork is removed. The mortar used in the present invention is the same as conventional mortar, namely Portland cement and river sand, mixed with water and various admixtures or additives added as necessary. The adhesive may be appropriately selected from known adhesives, taking into consideration the adhesive strength to concrete and the material of the decorative sheet. For example, if the back side of the decorative sheet is a fibrous sheet, organic solvent-based adhesives such as chloroprene solvent-based, vinegar-based solvents, and vinyl chloride copolymer solvent-based adhesives, emulsion-based adhesives such as vinegar emulsion, synthetic rubber emulsion, etc. Adhesives or polyurethane adhesives can be used. especially,
Emulsion adhesives, which are non-adhesive when applied and dried and are activated by moisture in mortar, are useful because they are easy to use and have strong adhesive strength. The decorative sheet is not particularly limited as long as it is suitable for use as an interior material or an exterior material. To give an example of a suitable decorative sheet, as shown in FIG. 3, a plastic layer (32) is placed on a fibrous sheet (31).
), a pattern printing layer (33) and a protective layer (34) are laminated in this order and embossed if desired. [Function] In the manufacturing method of the present invention, mortar is molded on a decorative sheet coated with an adhesive, so that the decorative sheet can be attached to a concrete board at the same time as molding. [Example] A decorative sheet for exterior material having the configuration shown in FIG. 3 was prepared.
This decorative sheet uses a vinylon nonwoven fabric (manufactured by Kojin Silbo Co., Ltd.) containing glass fiber and having a tsubo of 1509/m as the fibrous sheet (31), and one side of the vinylon nonwoven fabric (manufactured by Kojin Silbo) is made of plastic II (31).
2) Acrylic emulsion [Betaall 3
200J (manufactured by Sunstar Giken), a pattern (33) was printed with weather-resistant ink rVMcJ (manufactured by Moroboshi Ink), and a protective layer (34) with a thickness of 10μ was applied with fluororesin paint Lumiflon 302CJ (Asahi Glass WA). Apply adhesive "Penguin Cement 1000J (manufactured by Sunstar Chemical) to the other side of the nonwoven fabric of the decorative sheet, lay it on the floor with that side facing up, and place a wooden formwork (
Inner glue length 33 crn, width 330, depth 5 art
) was placed. Next, 35% Portland cement
A mortar consisting of 54% river sand and 11% water was poured into the formwork and left to stand. After the mortar had hardened, the formwork was removed to obtain the decorative concrete board shown in Figure 2. 1A) shows a concrete board. [Effects of the Invention] The manufacturing method of the present invention simplifies the process compared to the conventional method of pasting a decorative sheet on a concrete board, so the manufacturing method required for manufacturing a decorative concrete board is simplified. Time and labor can be shortened. Needless to say, this contributes to cost reduction. By selecting an appropriate decorative sheet layer structure and adhesive, it is possible to create a beautiful design with high weather resistance. 1q of products with .
