DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a tile.

[0002]

2. Description of the Related Art Conventionally, as a method of forming an uneven pattern on a tile surface made of a porcelain material, for example, an uneven surface is formed on an upper mold side, and the unevenness is formed on the surface of the tile substrate by pressing with the upper mold. Some are designed to form a pattern.

[0003]

In the above-mentioned conventional method, when a large number of tiles are formed by pressing with one type of upper mold, the tiles have the same uneven pattern, and the tiles have an irregular uneven pattern. Can not respond to the request.

Accordingly, an object of the present invention is to propose a method for producing a tile which can form various irregular patterns such as broken natural stones on the surface and has a non-slip effect. .

[0005]

According to the present invention, in order to solve the above-mentioned problems, a partially powdery refractory is placed on a surface of a tile base made of a porcelain material, and thereafter, the tile base is placed on the refractory. A pattern forming material made of a powdery porcelain material is laid on the entire upper surface, and these are pressed and formed into a tile shape, and then fired at a temperature at which the tile base and the pattern forming material directly contacting with the tile material melt, After the firing, the refractory is used as a peeling element to peel off the pattern forming material of the refractory portion,
An uneven pattern is formed on the tile surface.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. First, a powdery porcelain material is poured into a well-known concave tile forming form to a predetermined thickness to smooth the surface thereof, thereby producing a tile base 1 as shown in FIG.

Next, in the above-mentioned tile forming form,
A predetermined amount of powdery refractory 2, for example, chromium oxide, alumina, silicon, or the like, is scattered and distributed on the surface of the tile base 1 at random or in an appropriate pattern (FIG. 1).
(B) and FIG. 2). This mounting method is performed by artificially or mechanically spraying.

As a mechanical method, for example, a method previously filed by the present applicant in Japanese Patent Application No. 4-44507 is used. In this method, an accommodating portion for the powdery refractory 2 is provided near the above-described tile forming formwork, the accommodating portion is partitioned by a partition frame so as to have a desired pattern in a plane, and the refractory material is interposed between the partition frames. The refractory 2 is stored on the tile base 1 by removing the refractory 2 from the tile base 1 by removing the refractory 2 at the same time by adsorbing the different refractories 2 by the adsorbing means, moving the adsorbing means onto the tile forming form. Drop on the surface.

Next, in the above-mentioned tile forming form,
FIG.
As shown in (c), over the entire surface of the tile substrate 1,
In addition, the refractory 2 is thrown into a predetermined thickness covering the surface to level the surface.

Next, in the tile forming mold, the above-mentioned materials are simultaneously pressed by the upper die to form a tile. Then, after this pressure molding, it is taken out of the molding frame and fired by a firing machine.

The sintering temperature and sintering time are such that the tile base 1 and the pattern forming material 3 made of the porcelain material are melted, but the refractory 2 is not melted.
For example, when chromium oxide is used for the refractory 2, it is fired at a firing temperature of about 1200 ° C. to 1300 ° C. for about 60 minutes using a roller house kiln.

By this firing, the tile substrate 1 and the pattern forming material 3 are melted and fused and integrated with each other. However, since the refractory 2 is not melted, the refractory 2 and the surface of the tile base 1 are not fused and integrated, and the pattern forming material 3 a existing on the upper part of the refractory 2 is insulated from the tile base 1.

After the firing, the tile is cooled and taken out of the firing machine, and the tile is impacted with a hammer or other appropriate means. Then, since the refractory 2 and the tile base 1 are insulated from each other, the pattern forming material 3a in the portion where the refractory 2 exists is peeled off, and the pattern forming material 3 in other portions remains integrally with the tile base 1. I do. Therefore, as shown in FIG. 1D, the protrusions 3b are formed integrally with the tile base 1 by the remaining pattern forming material 3 on the surface of the tile, and other than the protrusions 3b, that is, the refractory 2 is The existing portion is formed in the recess 4.

In such an uneven surface, the boundary between the concave portion and the convex portion is stepped with an irregular partition line, and the concave surface is also a fine uneven surface, as if a natural stone was broken.

The tile base 1 in the powdered refractory 2 is melted by the firing of the tile base 1.
As shown in FIG. 3, a part 2a of the powder on the surface portion that directly contacts the tile body 1 may adhere to the tile base 1 and remain. Therefore, the concavity 4 is colored by the remaining color of the refractory 2a with the unique color of the refractory. For example, when chromium oxide is used, it is colored near green, and when alumina is used, it is colored white. Further, these may have other colors depending on the firing temperature.

[0016]

As described above, according to the present invention, various uneven patterns can be easily formed by appropriately distributing a powdery refractory, and the uneven patterns can be formed as if natural stone were broken. It can produce interesting tiles.

Further, the uneven surface can also exhibit a function of preventing slippage.
