Abstract

PURPOSE:To improve the slip proof function of tiles by roughening the surface of the tile base, then applying a glaze in which a surface tension reducing agent is dispersed on the surface of the tile and then firing. CONSTITUTION:The surface of the tile base 3 is preliminarily worked to have a net-like pattern including recessed part 1 and projected part 2 with pitch (p) and depth (d) by using a molding die having this pattern in the press-forming stage. Then, a high-viscosity glaze comprising feldspar, quartzite, clay, calcium silicate and frit is applied on the tile base by spray-coating. Further, the surface tension reducing agent comprising metal such as V, W, Mo, or its compd. such as V2O5 is sprayed thereon and fired. Thus, the inhomogeneous rough surface 6 with specified fine pitch and depth is formed to obtain the non-slip tile.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a non-slip tile whose surface has been subjected to anti-slip treatment and a method for manufacturing the same.

[Conventional technology]

Conventionally, non-slip tiles with anti-slip surfaces have been disclosed in Japanese Patent Laid-Open No. 62-128984 and Japanese Patent Laid-open No. 63159.
Some of them are disclosed in Japanese Patent Publication No. 278, Japanese Patent Application Laid-Open No. 2-55105, and the like.

Conventional methods for applying anti-slip properties to tiles include: ■ semi-embedding anti-slip materials such as hard particles into the surface of the molded product through press molding, or adding hard particles to the surface of dry or wet molded products. After that, a glaze is applied to the surface and fired to fix the hard particles to the surface; It is broadly divided into methods of forming the part.

However, in the above method of fixing the anti-slip material to the surface, as the surface wears, the non-slip material may be chipped off and the non-slip effect may be lost early, or the fixing material may take on a glass-like appearance, causing it to become slippery. The drawback is that it is slippery. In addition, in the method of forming irregularities mechanically on the surface of the tile base (ii) above, in order to give the formed irregularities an anti-slip function, it is necessary to form considerable steps or waves in the irregularities. However, when this material is used as a flooring material for a bath, limescale and organic residues of soapy water tend to adhere to it, making it slippery and requiring frequent cleaning.

[Problem to be solved by the invention]

The problem to be solved by the present invention is to solve the above-mentioned problems with conventional non-slip tiles.It has a high anti-slip effect, can maintain its anti-slip function for a long time without special maintenance and cleaning, and can be used barefoot in bathrooms etc. Our aim is to provide non-slip tiles that do not feel uncomfortable when touched.

[Means to solve the problem]

The non-slip tile according to the present invention is characterized by forming a glaze layer having an uneven surface formed on a substrate and an uneven surface different from the uneven surface.

This non-slip tile can be manufactured by forming irregularities on the tile base surface by pressing, sandblasting, scratching, or other mechanical means, and then using a surface tension reducing agent to form large and small irregularities on the glaze surface during firing.

[Effect]

The non-slip tile according to the present invention is produced by applying a glaze containing a surface tension reducing agent distributed on a tile base having a pre-formed uneven surface and firing the glaze, thereby forming innumerable large and small unevenness on the glazed surface of the tile.

〔Example〕

FIRST EMBODIMENT When the tile base is press-formed, the pitch p shown in the cross-sectional view of FIG.
A recess 1 of Q+y+m and depth d was formed in a net shape as shown in FIG.

Next, as shown in FIG. 3, a highly viscous material consisting of 50 parts by weight of feldspar, 10 parts by weight of silica, 5 parts by weight of clay, 20 parts by weight of wollastonite, and 15 parts by weight of frit is added to this tile base 3. Glaze 4 was applied to a thickness of 0.3 mm by spraying. Furthermore, as shown in FIG. 4, surface tension reducing agent V2
A 25% O5 aqueous solution was sprayed onto the glaze surface uniformly and then fired at 1250° C. for 50 minutes. As a result, as shown in FIG. 5, minute irregularities 6 with an average pitch of 3 to 5 mm and a depth of 0.2 to 2 mm were formed on the glaze surface. The characteristics of this unevenness were that the unevenness was large and the depressions had a matte appearance.

Second Embodiment Similar to the first embodiment, as shown in FIG.
After molding the tile base 3 having 2, it is fired at 1100°C. Next, as shown in FIG. 7, the same glaze 4 as in the first example was applied to a thickness of 0.55 mm.

On this first glaze 4, as shown in FIG.
, 1 mm thick, and furthermore, mixture 8 of WO2 and frit was sprinkled thereon and baked at 1200° C. for 60 minutes. As a result, as shown in Figure 9, the glaze surface has a depth of 5
Fine unevenness of 0 to 100 μm was formed. The characteristics of this unevenness were that, compared to the unevenness of Example 1, the unevenness was smaller overall and the degree of matteness of the recessed portions was mild.

Third Example In the first example, the glaze shown as 4 in FIG.
After applying the glaze to a thickness of 6 mm, 20% by weight of N H was applied on the glaze.
, VO3, and then calcined at 1250° C. for 3 hours. As a result, as shown in Figure 5, an average of 1
Non-uniform unevenness with a pitch of 0 mm and a depth of 0.1 to 11 T1 m was formed. The characteristic feature of this uneven structure was that it was a non-slip tile with a gentle degree of unevenness.

〔Effect of the invention〕

The following effects can be achieved by the present invention.

(1) In addition to the unevenness formed on the tile base itself, the glaze on top of it also has unevenness, which provides a great non-slip effect and prevents soap from getting mixed into the tile surface. The non-slip function will not be lost even in the presence of water.

[2] The surface of the tile is glazed with an uneven surface, so even if dirt gets on it, it can be washed immediately with water.

(3) When a plurality of colored glazes are used as the glaze, a rich variety of patterns can be obtained due to the presence of the uneven surface.

(4) To provide the non-slip function, dispersed particles are not buried in the glaze surface, and combined with the unevenness of the base material, the surface becomes moderately uneven, giving a good feeling of ground contact when walking barefoot. .
