Description

  The present invention relates to a method for manufacturing decorative ceramics, and more particularly, to a method for manufacturing decorative ceramics having improved design by using decorative objects.

  In addition to its essential functions, pottery is often given various decorations on its surface to enhance the overall aesthetics. As such decorations, in addition to the old Jomon, combs, cloths, finger presses, embossing of shells, plants and the like are known. There is also a known method of decorating with different materials. For example, a glass layer is formed in a hollow of a pottery such as a plate, a cup, or an ashtray, and water is accumulated there. The technology that gives the impression is known.

  However, the design of the technology for forming the glass layer described above is just as if water is in the bottom of the pottery, and a new technology can be added to improve the design. It is requested.

  The present inventor places various decorative objects such as dried plants (pressed flowers) such as flowers, star sand, etc. on the glass layer formed on the pottery on which the glass layer is formed, and cleans the resin on it. The idea was that if it was covered with a layer and allowed to cure, the decoration would appear to be present in the water.

  However, when the glass layer is simply covered with a resin layer and cured, there is a problem that peeling occurs with time and the practicality is remarkably lowered, and it has been necessary to eliminate this point.

  The present invention has been made under the above circumstances, and even if a decorative object on a glass layer is coated and cured with a resin layer, the resin layer does not peel off from the glass layer, and the decoration can maintain aesthetics for a long time. The issue is to provide a method for producing ceramics.

  The present inventor has been diligently studying a method for preventing the separation between the glass layer and the resin layer, and by forming a film with a specific adhesive prior to the formation of the resin layer, the time course between the glass layer and the resin layer is increased. The present invention was completed by discovering that proper peeling can be prevented.

  That is, according to the present invention, an adhesive layer is formed on a glass layer formed in a pit of a pottery, and then a desired ornament is placed on the adhesive layer, and then a resin material is filled thereinto, and light is applied to this. Or it is the manufacturing method of the decorative ceramics characterized by irradiating and hardening | curing an ultraviolet-ray.

  According to the method for producing a decorative ceramic of the present invention, there is provided a ceramic having a decorative object sealed in a light-curing or ultraviolet effect resin fixed on a glass layer provided on the ceramic. In order to give the impression that it exists in water, it can be used as a dish, cup, ashtray, decorative tile, decorative ceramic piece, etc.

It is drawing which shows typically an example of the manufacturing process of the decorative ceramics of this invention.

According to the present invention, decorative ceramics are
(1) Glass layer forming step (2) Adhesive layer forming step (3) Decorative article placing step (4) Manufactured by each step of resin coating / curing step.

  Among these steps, the glass layer forming step (1) is a step of forming a glass layer on the pottery. This process is schematically shown by A, B, and C in FIG.

  This process consists of a glass piece, glass sand, etc., as a raw material for the glass layer in the recess 2 of the substrate (1a) in the shape of a dish, cup, ashtray, decorative tile, decorative ceramic piece, etc. (hereinafter referred to as “ceramic”) ( Hereinafter, it is referred to as “glass raw material”; 3a) is added, and this is performed by raising the temperature to a temperature at which the substrate and the glass raw material are fired together.

  The substrate used in the present invention is not particularly limited in its shape and size as long as the glass material melts to form a glass layer. Moreover, although the base material is formed of porcelain clay, there is no particular restriction on the porcelain clay, and clay or the like generally used for pottery can be used. Furthermore, although there is no restriction | limiting in particular also as a glass material, What was called cullet which collected the crushed glass piece, for example, the average particle diameter of about 2-5 mm, and the thing of the same color, can be utilized. Further, if necessary, a luminescent powder may be used together with the glass material. By doing in this way, the glass layer after baking can emit a nightlight, and aesthetics can be improved more.

  In this step, the substrate in which the glass material or the like is put in the depression is at a temperature not lower than the temperature at which the glass powder is melted to form a glass layer, preferably at a temperature of about 1150 to 1250 ° C., preferably for about 5 to 6 hours, preferably Is fired for about 6 to 20 hours, more preferably for about 12 to 20 hours. By doing so, a glass layer 3 is formed in the recess 2 of the pottery 1b as shown by C in FIG.

  In addition, the above-mentioned substrate may be used after it has been shaped with porcelain and then simply dried, and it may be directly baked. However, the substrate after glaze is applied to the substrate formed with porcelain and dried. Alternatively, it is possible to use a material that has been glazed and then unglazed, and a glass material or the like is placed in this recess and baked. When firing using a base treated with glaze, the adhesion between the glassy layer formed from the glaze by firing and the glass layer is higher than in the case of direct clay, and problems such as peeling are less likely to occur. Moreover, if a glaze is used as a glaze, the color of the glass layer of a dent, and the earthenware with contrast and harmony can be prepared.

  Next, an adhesive layer 4 is formed on the upper surface including the glass layer of the earthenware baked in the above step 1 as shown in FIG. 1D (step (2)).

  The part where the adhesive layer is formed is preferably the same as or slightly larger than the part to be coated with the resin material in a later step. Moreover, as an adhesive agent used for formation of an adhesive bond layer, what does not require processes, such as a heating, is preferable, for example, it is preferable to use two liquid adhesives, such as an epoxy type.

  This adhesive layer is preferably applied thinly and uniformly. In addition, since what is generally used as an adhesive is used here, it is expressed as an adhesive layer. However, the adhesive is generally bonded between solids and is in a liquid state as in the present invention. It cannot be said that the resin material having fluidity is used as an adhesive.

  Next, the decoration 5 is placed on the glass layer 3b whose surface is covered with the adhesive layer 4 as shown by E in FIG. 1 (step (3)).

  The decoration placed on this glass layer is preferably one that contains no or almost no moisture or other liquid components, examples of which are star sand that is fine coral fragments, small shells of shells, Examples thereof include dry plants such as pressed flowers, metal pieces, metal-polymer composite material pieces such as lame, and dried insects. Since these ornaments are fixed by the adhesive layer, their positions are hardly changed even when they are covered with a resin material in the next step.

  As described above, the ornament placed on the glass layer is further coated with the resin material 6a as shown by F in FIG. 1 and then cured (step (4)).

  The resin material used for coating in this step is light or ultraviolet (hereinafter referred to as “UV”) curable resin, and various materials can be used as long as they have such properties. Specifically, an unsaturated polyester resin material such as UV curable acrylate can be used.

  This resin material is preferably one that retains transparency even after curing, and is preferably liquid in terms of filling properties.

  Finally, the ornament covered with the resin material is irradiated with light or UV having the intensity specified by the resin material and cured. Since the wavelength and intensity of light in this step vary depending on the resin material, it may be carried out according to the instructions for the resin material.

  By doing in this way, a decoration is enclosed in the resin material on a glass layer. In this state, it is slightly sticky, but further, for example, by exposure to sunlight, curing proceeds and a complete decorative ceramic is obtained.

  Note that the coating step and the curing step with the resin material may be performed once, but repeating a plurality of times, for example, about 2 to 5 times, thickens the resin layer and encloses the decoration in the back of the resin layer. It is preferable because the surface of the resin layer becomes smooth. This state is shown in FIG.

  In this way, when coating with resin material and curing by light or UV irradiation are repeated, after coating with resin material, irradiation with light or UV of specified intensity is cured and then coated again with resin material. What is necessary is just to repeat the process made to harden.

  In addition, since the resin layer after curing by light or UV irradiation remains slightly sticky as described above, when covering and curing are repeated, after placing the decorative object on the resin layer again, Coating and solidification can be repeated. By doing in this way, it is also possible to arrange the ornaments at several positions with different depths (heights). Moreover, if a powdery light-emitting paint (light-glow powder) is spread on the resin layer on which the slight stickiness remains, light can be emitted by light.

  By doing as described above, a decorative pottery in which a decorative article is enclosed in a transparent resin can be easily obtained, and this article has durability over time.

  EXAMPLES Next, although an Example is given and this invention is demonstrated in more detail, this invention is not restrict | limited at all by these Examples.

Example 1
Manufacture of decorative tile pieces (1):
A red clay for ceramics produced in Onna Village, Okinawa Prefecture was collected, and a tile base having a diameter of about 10 cm and a thickness of about 10 mm was prepared. A recess having a diameter of about 2.5 cm and a depth of about 6 mm was formed in the center of the substrate.

  The tile substrate was covered with a cobalt cocoon and air-dried for 2 to 3 hours, and then a blue cullet (average particle size: 2 mm to 5 mm) was put into the depression until the 8th minute. This was fired at 1250 ° C. for 17 hours in a ceramic gas furnace. As a result, tile pieces having a glass layer formed up to about 40% in the depressions were formed.

  After firing, the product temperature is lowered to room temperature over 2 days, and epoxy two-component adhesive (Bondquick 5 (for metal, glass, ceramics)) / manufactured by Konishi ) Was applied thinly. Place several star sand and small flower pressed flowers on the glass layer, and UV curable resin (trade name: trade name; KIYOARA UV craft resin liquid, UV curable resin liquid (hard type) / manufactured by Kiyohara Co., Ltd.) Was injected and coated.

  Using a UV irradiation device (GELNAIL UV LIGHT (DIVA-UV36w)), the UV curable resin layer was cured by irradiating with UV for 120 seconds. Then, it was again coated with the same UV curable resin and irradiated with UV under the same conditions. This was repeated once more.

  Finally, the tile pieces were taken outdoors and exposed to sunlight for 12 hours. The surface of the UV cured resin of the obtained tile piece had no stickiness, and star sand and pressed flowers as decorations were neatly enclosed in a transparent resin.

Example 2
Manufacture of decorative tile pieces (2):
In the same manner as in Example 1, a tile piece on which a glass layer was formed was obtained. An epoxy two-component adhesive was applied thereto in the same manner as in Example 1, and a small flower pressed flower was placed thereon, followed by coating with a UV curable resin, followed by curing as in Example 1.

  Next, on the UV curable resin still sticky, place star sand and powdered luminescent paint (trade name: Yakko Powder / manufactured by Pepares Mfg. Co., Ltd.), cover with the same UV curable resin, and cure by UV irradiation. It was. This process was repeated again.

  Finally, as in Example 1, the tile pieces were exposed to sunlight. The surface of the UV cured resin of the obtained tile piece had no stickiness, and the star sand, pressed flowers, star sand and luminescent paint as decorations were neatly enclosed at different heights in the transparent resin.

  The tile pieces prepared in Examples 1 and 2 were placed outdoors and subjected to an exposure test. However, no peeling was observed between the pottery part and the cured resin part enclosing the decoration over a long period of time.
