Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone-faced tile formed by devising a combination of glazes and a glaze application method in a step of applying a glaze to a tile base.

[0002]

2. Description of the Related Art Conventionally, in order to obtain a stone-faced tile, a stone-faced pattern print is transferred to a tile base, a stone-faced pattern is screen-printed, or a plurality of colored kneaded clays are mixed. A method such as dry press-molding the formed product has been used.

[0003]

However, in the prior art, in the construction of the stone-faced tile by printing / printing,
Print transfer and printing on the tile side edge are impossible. Further, the method using a colored kneaded clay requires a lot of pigments, and the process is complicated, resulting in cost increase. In addition, in recent years, there is a demand for a tile surface pattern having a different personality from others, and this is also true for stone-faced tiles.

[0004]

DISCLOSURE OF THE INVENTION The present invention provides a stone-faced tile by glaze. As a result, it is possible to obtain a stone surface pattern on the entire surface of the tile base material, and it is not necessary to grind the tile surface. That is, on the surface of the tile base material, bright (gloss) which is a base glaze with high melt viscosity
After the lower glaze or the matte lower glaze is applied to the glaze or the sprinkled glaze, the bright glaze or the matte glaze, which has a lower melting viscosity than the base glaze, is sprayed or centrifugally applied to the glaze to make a stone surface condition. It uses the means of getting tiles.

[0005]

The present invention has the following effects by using the above means. When a glaze with a low melt viscosity is applied to a base glaze with a high melt viscosity in a mottled state, it is in a state in which it flows easily at the time when the above glaze that has been mottled in a mottled state melts. It is possible to settle and obtain tiles with a unique stone-like surface.

EXAMPLES Examples of the present invention will be described below with reference to the attached tables or drawings. The present invention forms a stone-faced tile having a unique pattern by combining the base glaze A and the button glaze B. First, the blending and combination of the base glaze A and the button glaze B are shown in Table 1. Description will be made based on Table 2.

Table 1 shows the range of glaze preparation.
Table 2 shows the combinations of glazes. The base glaze A includes a bright bright lower glaze A1 and a matte matte lower glaze A2. In addition, in the button glaze B,
Similarly, there are bright spots B1 and matte spots B2. The composition of these glazes is as shown in Table 1, and the glaze is constituted by adding a pigment to the basic glaze constituted by the composition based on Table 1. There are six types of combinations of the base glaze A and the button glaze B as shown in Table 2, and as shown in patterns 3 and 6, the button glaze B has bright spots B1.
And both the matte spots B2 may be glazed.

[0008]

[Table 1]

[0009]

[Table 2]

Next, the method of glaze will be described. First,
Glazed base glaze A by curtain or pouring. FIG.
2 shows the structure of the curtain hanging device M for the base glaze A, FIG. 1 is a perspective view thereof, and FIG. 2 is a front view thereof. The tile base T placed on the tile placing plate 2 is carried by the belt 1 and is flown in a waterfall shape from the glaze tank 3 through the curtain 4 by the base glaze A (bright lower glaze A1 or mat lower glaze A2). The surface is glazed.

The tile base material T, the surface of which is glazed with the base glaze A, is then glazed with the button glaze B by spraying or centrifuging. FIG. 3 and FIG. 4 are perspective views of the spraying device S for the button glaze B, and FIG. 5 is a front view. Explaining with reference to FIG. 3, as in FIG. 1, the base glaze A has already been glazed on the surface of the tile base material T conveyed on the belt 1, and the bright spot B1 which is the button glaze B from above. Alternatively, the matte spot B2 is sprayed with
Spray 2-7 times. When it is desired to obtain a combination of patterns 3 or 6 in Table 2, the spray spots B1 are sprayed from the spray 5a and the mat spots 5b are sprayed from the spray 5a in FIG.

The tile surface thus glazed has a high melt viscosity of the base glaze A and a low melt viscosity of the button glaze B. Therefore, as shown in FIG. 6, the button glaze B is melted and soaked on the base glaze A. It becomes such a state, and it becomes a unique stone tone.

The glazed tiles are rolled by a roller hearth kiln for 20 to 60 minutes at 1070 to 1150 ° C.
Firing at moderate temperature completes the construction of the stone facing tile. As a method of giving a metallic luster to the tile surface, a raster treatment may be performed thereafter. In the raster process, when tiles that have been fired with a roller hearth kiln are passed through a gas obtained by evaporating a liquid made of an alkoxide of titanium dioxide or a vanadium alloy, these gases are vapor-deposited on the surface of the tile and have a metallic luster. The tile surface can be obtained.

[0014]

Since the present invention is configured as described above, it has the following effects. Since it is configured as in claim 1, a stone-faced tile having a surface of a unique color tone can be obtained. Since the surface is decorated by glazing, unlike the tile surface by printing or printing, where the side edges cannot be decorated, stone surface decoration is applied over the entire surface of the tile. In addition, a stone-faced tile is constructed more easily and more quickly than the method of polishing the surface by mixing white and black powder into the tile base material.
