DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of a ceramic product and a method for producing the same according to the present invention will be described. FIG. 1 is an embodiment of a ceramic product according to the present invention, in which (1) is a plan view and (2) is a cross-sectional view taken along the line AA in (1).

Reference numeral 1 denotes a square ceramic base material, for example, a ceramic plate or a tile. That is, it is fired at a temperature of, for example, about 920 ° C. after molding. A concave pattern is formed on the surface of the ceramic base material 1 by sandblasting from above the mask, and a filling material 2 of glass, synthetic resin, or the like is filled therein.

Depending on the pattern shape of the recess pattern, it can be used as a decorative article. When the recess pattern is a character or the like, it can be used as a nameplate or an inscription display.

FIG. 2 is a diagram for explaining a method of manufacturing this ceramic product in the order of steps. As shown in (1), a ceramic base material 1 such as a ceramic plate or a tile, for example, a rectangular or other shaped plate made of clay or the like and then unbaked at about 920 ° C. is prepared.

As shown in (2), a sandblasting mask 3 is overlaid on the surface of the ceramic substrate 1 and adhered thereto. The mask 3 is, for example, a pattern-shaped one in which a pattern 3a corresponding to a pattern to be formed is cut out, and is formed of a synthetic resin sheet or the like.

Therefore, in the sand blasting step (3), when sand blasting is performed from above the mask 3 with the nozzle 5, the portion 3 of the window hole cut out of the mask 3 is formed.
The blasting sand passes only in the area a, and the ceramic substrate 1
Is ground to form a concave pattern 4.

The area 3b where there is no window hole 3a cannot pass through the blasting sand and is rebounded.
Is not ground. In addition, the nozzle 5 for sandblast is located above the ceramic substrate 1.
In order to move in the X and Y directions so as to scan over the entire surface, it is possible to grind only the window hole 3a of the mask 3 over the entire surface of the ceramic base material 1 to carve the recess pattern 4. it can.

In order to uniformly carve the recess pattern 4, a nozzle 5 having a size of 3 mm or more is used. If the size of the ceramic substrate 1 is 20 × 20 cm, sandblasting is performed for about 8 minutes or more. .

Next, when the mask 3 is peeled off and removed,
As shown in (4), the ceramic substrate 1 having the concave pattern 4 formed on the surface is obtained. Next, as shown in (5), the synthetic resin 6 such as urethane resin is filled in the concave pattern 4 formed in the previous step. At this time, if a curing agent is added and mixed in addition to the main agent, the mixture is cured by being left for about one hour. In addition, desired coloring is possible by adding a pigment.

The mask 3 can be a mask that is commercially available under the name of, for example, a cutting sheet or an Arthur mask.

After the step (4), a glass material can be filled instead of the synthetic resin 6. That is, in FIG. 3, after the step (4), the glass material 7 is filled in the concave pattern 4 in the step (5). Then, in the step (6), the ceramic base material 1
When refired at a temperature of about 0 ° C., the glass material 7 is melted and welded to the inner surface of the concave pattern 4.

2 and 3, if the surface of the ceramic substrate 1 is sprayed with a spray gun with a spray gun or the like, the surface of the ceramic substrate 1 is covered with glass. As a result, adhesion of dirt can be prevented, and gloss is improved.

As the ceramic substrate 1, it is preferable to use an unglazed product of a ceramic plate fired with high-quality clay or a tile fired with relatively low-quality clay in order to prevent deformation. To form a concave pattern. In addition, not only these but also set products such as dishes can be used as the ceramic base material.

In the above description, the concave pattern of the ceramic substrate 1 is filled with a synthetic resin or a glass material to produce a product. FIG. 4 shows another example in which the glass pattern formed by the concave pattern of the ceramic substrate 1 is removed. This is an embodiment of a method in which a product is fixed to a stone or the like to form a product.

The recess pattern 4 shown in FIG.
As shown in (5), a powder (for example, a powder called “chamotte”) 8 having a higher melting point than the glass material is laid. At this time, the powder 8 is also attached to the inner wall of the concave pattern 4.

Next, as shown in (6), when the glass material 7 is filled on the high melting point powder 8 and fired at a temperature at which the glass material 7 is melted, the glass material 7 is melted.

After taking the ceramic substrate 1 out of the furnace and allowing it to cool naturally, the glass pattern 7a is taken out of the concave pattern 4 of the ceramic substrate 1. Then, as shown in (8), the adhesive 11 is applied to the concave pattern 10 formed in advance on the stone material 9, and the glass pattern 7a is inserted and fixed thereon by means of (9).

The concave pattern 10 in the stone 9 is formed to have a larger width and depth by the amount of the adhesive 11.

Without forming the recess pattern 10, the stone 9
It is also possible to bond and fix the glass pattern 7a on a flat surface such as the above. As described above, when the concave pattern 10 is not formed, there is no problem in processing the concave pattern, so that a material other than a stone can be used.

[0032]

EXAMPLE As shown in FIG. 3, when a glass material 7 is filled in a concave pattern 4 of a ceramic base material 1 and melted, a frit powder called M802 manufactured by Nissin Sangyo Co., Ltd. is used as the glass material 7. And a colorant composed of a metal compound at a predetermined ratio. Next, water was added to the mixture to suspend the mixture, and the mixture was filled in the recess pattern 4 with a pipette, and the mixture was dried. In addition, it is also possible to fill as dry powder without adding moisture.

Next, 920 ° C. to 100 ° C. using an electric furnace.
Calcination in air at a temperature of 0 ° C. In addition, it is also possible to use a gas kiln or a kerosene kiln for firing. The firing temperature and atmosphere can be selected according to the glass material.

Table 1 shows the change in color tone when firing was performed by changing the colorant and the blending amount in this example.

[0035]

[Table 1]

As can be seen from Table 1, various colors can be obtained by selecting the type and amount of the coloring material, so that ceramic materials such as porcelain plates and tiles, stone materials and the like can be arbitrarily colored. It is capable of forming and displaying patterns such as patterns and characters, and is most suitable as a decorative article that can be installed indoors and outdoors or fitted into a wall, as a building material with a high design, or as a display article.

[0037]

According to the first aspect, since the concave pattern formed on the ceramic base material is filled with a filler such as glass or synthetic resin, the same pattern is formed by sandblasting using a mask. It can be formed in large quantities and mass production becomes possible.

Further, if the ceramic base material once fired is used, there is no fear of dimensional change or deformation. Glass, synthetic resin, or the like that fills the concave pattern is easily adapted to the concave pattern and can be easily colored, so that a complicated and arbitrary pattern can be formed, which is optimal as a decorative article or a display means.

According to the second aspect, since the concave pattern is formed by sandblasting on the ceramic base material before or after firing, the same pattern can be mass-produced by processing with sandblasting from above the mask. Since the concave pattern is filled with a synthetic resin or the like and hardened, it can be easily manufactured.

According to the third aspect, since the concave portion pattern is filled with a glass material and refired, the production becomes complicated,
Because it is filled with glass, glossiness is better than synthetic resin, especially when installed in a place where natural light shines,
Products with excellent quality can be realized.

According to the fourth aspect, a method is used in which a pattern is formed of a glass material using a concave pattern formed in a ceramic base material, which is taken out and adhered and fixed to another stone or the like. It is possible to form a pattern with a glass material even on a stone material or the like that may be rubbed, and it can be applied to various base materials.
