Abstract

PURPOSE:To provide a tile whose surface possesses a metallic color and feel of a material. CONSTITUTION:Metallic powders 2, 3, 4 are put on the surface of a tile body 1 comprised of a porcelain material. The same is fired at a temperature wherein both of 1 and 2, 3, 4 are melted and both of them are integrated. Colors intrinsic to their metals are made to generate by firing of the metallic powders 2, 3, 4.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a method for manufacturing tiles.

[0002]

2. Description of the Related Art Conventionally, in a porcelain tile that is used by being attached to the wall surface of a building, the surface of the tile has the color and texture of porcelain.

[0003]

By the way, a wall surface in a building is required to have various colors, textures, etc. from the viewpoint of design, but in the conventional porcelain tiles used for adhering to the concrete wall surface or the like, , The surface of the tile had the color and texture of porcelain, and it was not possible to finish the concrete wall surface with the color and texture of metal by the tile.

Therefore, an object of the present invention is to propose a method for manufacturing a tile in which a tile having a metal color or texture is formed.

[0005]

In order to solve the above-mentioned problems, the present invention places a metal powder on the surface of a tile base made of a porcelain material and press-molds it. It is characterized in that both are melted and integrated by firing at a temperature at which the metal powder melts.

[0006]

EXAMPLES Examples of the tile manufacturing method of the present invention will be described below. First, a powdered porcelain material having a predetermined thickness is put into a concave tile forming frame to smooth the surface thereof, and a tile base 1 as shown in FIG. 1 is produced.

Next, a plurality of different metal powders 2, 3,
4 is placed on the surface of the tile base 1 in a predetermined amount so as to be distributed randomly or in an appropriate pattern. This placement method is performed by artificially or mechanically spraying.

As a mechanical method, for example, the method previously filed by the present applicant in Japanese Patent Application No. 4-44507 is used. In this method, a storage part for the metal powder is provided in the vicinity of the above-mentioned tile forming frame, the storage part is partitioned by a partition frame so as to have a desired pattern on a plane, and a different metal powder is placed between the partition frames. The metal powder is stored, and these different kinds of metal powder are simultaneously adsorbed by the adsorbing means, the adsorbing means is moved to the tile forming frame, the adsorbing force is removed, and the metal powder is dropped on the surface of the tile base 1.

As the metal powder, for example, powder 2 made of iron 2, powder 3 made of copper and powder 4 made of nickel were used. The powders are not limited to these powders, and powders made of other metals, such as cobalt powders, may be used depending on the color demand.

After placing the metal powders 2, 3 and 4 as described above, the metal powders 2, 3 and 4 and the porcelain material of the tile base 1 are simultaneously pressed by the upper mold. Then, this is taken out from the molding frame and fired by a firing machine. This firing is carried out by any one of oxidation flame firing, reduction flame firing, and neutral flame firing.

When the above materials are used, for example, when using a roller house kiln, about 1200 ° C. to 1300 ° C.
The tile base 1 made of a porcelain material and the metal powders 2, 3 and 4 are melted by baking at a baking temperature of 60 ° C. for about 60 minutes, and the two are integrated by fusion bonding.

As the firing method, it is also possible to use a tunnel kiln, a shuttle kiln, or the like for firing for a predetermined time during which the above-described melt adhesion is performed. After the above firing, the tile is slowly cooled and taken out from the firing machine.

By the above-mentioned firing, the metal powder undergoes oxidative discoloration in the case of oxidative flame firing by strong heat, reductive discoloration in the case of reduction flame firing, and neutral discoloration in the case of neutral flame firing. For example, the above-mentioned iron powder 2 changes its color to a color close to black, and the copper powder 3 changes its color to a color close to green,
Nickel powder 4 discolors to a color close to brown. Also, when cobalt powder is used, the color changes to a color close to blue.

The amount of the metal powder to be placed is increased or decreased on each surface when the unevenness pattern is formed on the surface of the tile. Further, in the portion where the amount is large, as shown in FIG. 3, gas is generated inside the portion a and a copper bronze portion b is formed. Therefore, the part (a) has a color or pattern in which the metal is rusted and tattered, and is formed on the attractive surface.

The tile base material 1 before firing may be formed by a dry method using a mold as described above, or may be a wet method in which a clay-like material is extruded from a mold cavity.
In the case of this wet method, the tile base material is extruded to a predetermined thickness, cut into a desired length, and thereafter, the metal powder as described above is sprinkled on the surface of the tile base material and slightly Pressurize. Then, this is fired as described above.

Alternatively, the tile base material may be extruded to a predetermined thickness, the metal powder may be sprinkled on the tile base material, and then this may be slightly pressurized to be cut into a predetermined length and then fired. Good.

[0017]

As described above, according to the present invention, it is possible to give a metallic color and a metallic texture to the surface of the tile base made of a porcelain material. It is possible to form a quaint wall surface having a metallic color and a metallic texture.
