Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile having a matte glaze layer as a surface layer.

[0002]

2. Description of the Related Art Conventionally, various glazes have been applied to the tile surface to decorate the tile surface. As such a glaze, one having a transparent surface gloss is generally preferred, but conversely, a matte glaze having no surface gloss is also preferred, and it is widely used as a glaze for tiles along with the gloss glaze.

In this matte glaze, fine particles and crystals are suspended in the glaze, so that the light entering the glaze layer is reflected, refracted, and scattered into a matte form.
Conventionally, when this matte glaze is applied to the tile surface, various pigments are contained in the glaze to color the matte glaze in various colors, but in general, this matte glaze is in a state of hiding the lower side. Since it is often used, the conventional matte glazed tile has a drawback that it lacks a feeling of depth and depth.

[0004]

The present invention has been made to solve the above problems, and the gist thereof is to form a colored lower glaze layer on the surface of a tile base material, and further to form the colored lower glaze layer. There is a semi-transparent matte glaze layer on the top.

[0005]

As described above, according to the present invention, a semi-transparent matte glaze is applied to the surface of a tile and a colored lower glaze layer is formed on the lower side of the matte glaze. In the case of the tile of the present invention, the lower glaze is used. The color of the layers is translucent through the matte glaze layer and floats on the surface, revealing a aesthetic feeling with depth and depth.

The matte glazed tile of the present invention has an aesthetic appearance similar to that of the case where a colored layer is formed on the back side of frosted glass, so that the color of the lower glaze and the aesthetic characteristic of the matte glaze are well fused and harmonized. It has an unprecedented unique aesthetic.

The basic composition of the lower glaze of the matte glazed tile of the present invention is expressed by the Zegel method as K ₂ O: 0.20 to 0.25 Na ₂ O: 0.30 to 0.35 CaO: 0.40. 0.45 ZnO: 0.1 or less _{Al 2 O 3: 0.7~0.8 SiO 2} : 6.0~7.0 B 2 O 3: 0.1~0.3 ZrO 2: 0.15 or less Can be

Further, as a basic formulation of the semitransparent matte glaze, K ₂ O: 0.03 to 0.05 Na ₂ O: 0.10 to 0.12 CaO: 0.45 to 0.47 ZnO: _{0.40~0.42 Al 2 O 3: 0.35~0.40 SiO} 2: 3.25~3.60 B 2 O 3: can be 0.15 or less.

[0009]

EXAMPLES In order to further clarify the characteristics of the present invention, examples thereof will be described in detail below. Zegeru type display in _{K 2 O: 0.22 Na 2 O} : 0.31 CaO: 0.43 ZnO: 0.04 Al 2 O 3: 0.76 SiO 2: 6.25 B 2 O 3: 0.19 Zrcon is added to the composition consisting of ZrO ₂ : 0.11 in an amount of 20%, a predetermined tea pigment is 0.4%, a blue pigment is 4.0%, and a yellow pigment is 3.0% in an outer percentage. Then, the obtained glaze having a specific gravity of 1.65 (lower glaze 12 in FIG. 1) was glazed on the unglazed tile base material 10 by a curtain so that the wet weight was 13.5 g / 15 × 15 (cm).

On top of that, from K ₂ O: 0.05 Na ₂ O: 0.10 CaO: 0.45 ZnO: 0.40 Al ₂ O ₃ : 0.36 SiO ₂ : 3.22 by the Zegel formula. A glaze having a specific gravity of 1.67 (matte glaze 14) was glazed by a curtain with a wet weight of 27 g / 15 × 15 (cm) and baked under conditions of a maximum temperature of 1080 ° C. and a baking time of 17 hours.

As a result, a matte glazed tile having a depth feeling and a transparent feeling visible on the surface was obtained through the matte glaze 14 in which the color of the green lower glaze 12 was translucent. Incidentally, the results of measuring the characteristics of this surface are shown in [Table 1]. In addition, Table 1 also shows the measurement results when white, blue-green, and brown colors were used as the lower glaze.

[0012]

[Table 1]

However, in this table, the glossiness Gs 60 ° is
It is obtained by measuring the reflected light flux when the sample surface is irradiated with light at an incident angle of 60 degrees, and the larger this value, the more glossy it is.

Further, the values of L *, a *, b *, and Δa * b * are values based on the CIEL * a * b * display system, where L * is lightness, a * and b * are tints, and Δa *. b * represents the saturation.

The matte glazed tile of this embodiment has a feature that the lower glaze 12 contains an opacifying agent and does not cause a problem of water absorption coloration in the tile. Water absorption coloration is a phenomenon in which the tile absorbs moisture such as in mortar to cause a ring-shaped coloration on the surface, and the appearance of the tile is impaired when this water absorption coloration occurs, but the tile of this example is Due to the effect of the opacifying agent in the glaze 12, this water absorption coloring can be prevented.

Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention is applicable to tiles of various materials or tiles of various sizes. The present invention can be implemented in a mode in which various changes are made based on the knowledge of those skilled in the art without departing from the spirit of the invention.
