Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anti-slip tile used for constructing bathroom floors, etc., and a method for manufacturing the same.

Conventionally, as a manufacturing method for anti-slip tiles, the patent application 1986-
There is one related to No. 153929 (Japanese Unexamined Patent Publication No. 53-78629). That is, as shown in the first diagram, a glaze 3 is applied to the surface 2a of the tile base 2, and one or more fine particles 4 made of molten alumina, porcelain, etc. having a fire resistance higher than the final firing temperature are applied. Groups are dispersed on the substrate surface 2a through an adhesive layer such as starch paste or adhesive layer 5, and if desired, a glaze 6 is further applied thereon as shown in FIG. 1(C). The fine particles 4, 4... are adhered and fixed to the surface of the tile body by firing, and the particle diameter of the fine particles 4 is set to 0.1 to 0.8I.
In this manufacturing method, the final firing temperature is set to 800° C. or higher or a temperature at which the fine particles 4 do not melt completely.

However, the above manufacturing method has the following drawbacks.

■ When the fine particles 4, 4, etc., which are dispersed on the glaze 3 through the adhesive layer 5, are fired as shown in FIG. 4,4・
... was sinking in.

■ When the glaze 6 is applied and fired as shown in Figure 1 (C1), the glaze 6 is fine particles 4,
4. Glaze with...! 13 side, and it was sometimes impossible to form a predetermined anti-slip protrusion on the tile body.

(2) The phenomena of (1) and (2) above are remarkable when the particle size of the fine particles 4 is particularly fine. Therefore, in the conventional method, it was impossible to use fine particles of less than 0.1 arm due to the thinning limit of the glaze thickness. It is necessary to use particles of I 111 or higher, and the tiles obtained in this case may cause damage to bare feet, making it difficult to manufacture anti-slip tiles that have an appropriate anti-slip effect. I could not do it.

The object of the present invention is to provide an anti-slip tile using fine particles of less than 0.1 square centimeters, which was previously impossible to manufacture, and a method for manufacturing the same.

The gist of the present invention is that, in an anti-slip tile, a base glaze layer is formed to cover a suitable place on the surface of the tile base, and fine particles with a particle size of 0.0601 m or more and less than 0.1 u+ are bonded to the suitable place on the surface of the base glaze layer. In addition, in the manufacturing method of the anti-slip tile, the surface of the tile base has a fluidity of 2.0 cm or less as measured by an inclined button tester. An adhesive glaze that forms a base glaze layer using a base glaze that has a higher melting point than the base glaze. ,,,i□9□□4□tsu,8 o,oe A suspension of fine particles with a size of +nm or more and 0.1 +u+ is applied to the surface of the base glaze layer, and the base glaze and adhesive glaze are combined. The goal is to fire at a temperature above the melting temperature and below the eutectic temperature of the adhesive glaze and fine particles.

Hereinafter, the method for manufacturing the anti-slip tile according to the present invention will be explained as shown in Fig. 2 (
2) Description will be made based on the embodiment shown in 0.

In the first step, as shown in the second diagram, a base glaze layer 13 is applied to the entire surface of the surface 8a of the tile base 8 or a base glaze 9 at appropriate places.
No. 11113a is formed to have a thickness A (for example, a glazed thickness A such that the thickness A' after firing as shown in FIG. 3 is -0.02 to 0.031). The tile base 8
is obtained by a known dry pressure molding method, wet extrusion molding method, or the like. The base glaze 9 has a measured value L (see FIG. 4B) of a tilted type bureau, which will be described later, of 1'-=2.0.
A material having a fluidity of 0- or less is used. As shown in the fourth diagram, the tilted button test is performed by tilting the surface 8'a of the unglazed tile base 8' obtained by unglazing the tile base 8 at an angle of θ-25 degrees with respect to the horizontal plane, and ,
D=1.0cmφ, H-1.0cm on surface 8'a
A test glaze block 9' was bonded with vinegar-vinyl resin (not shown), heated to a predetermined firing temperature T1 (described later), maintained at temperature T1 for 30 minutes, and then slowly cooled. Surface 8' of tile ground 8' shown in Figure 0
The flow length of the molten glaze 9' at point a is measured, and the fluidity of the glaze is evaluated based on this measured value. Na'
The test glaze block 9/ is obtained by pressure-molding the dried glaze i, og that has passed through a 100-mesh sieve into a short cylindrical shape.

In the first planning step, as shown in the second diagram, the measured value of the tilt button test is set at an arbitrary point on the first m13a to be L=2.
The second base glaze layer 13 is formed by the base glaze 10 with a thickness of 0 cm or less.
The layer 13b is formed to have a desired thickness B (for example, a glazed thickness B such that the thickness after firing is B' -0.05 to 0.1 ii+ as shown in FIG. 3). The glazing of the base glaze 10 is carried out by a known glazing method such as a machine bottoning method or a screen printing machine printing method. Note that the second step is formed as necessary for the purpose of improving the anti-slip effect and/or the design effect of the second step 21113b, and can of course be omitted.

In the third step, as shown in FIG. 2(B), the base glaze 1
Although not shown, the adhesive glaze 11 is applied to the appropriate place on the surface of 113 in advance.
The suspension 15 in which fine particles 14 are suspended is 0.5~
2. OQ/10 cm square is coated to obtain a substrate 16. As the adhesive glaze 11, a glaze having a higher melting point (for example, about 100° C. higher) than the base glaze 9.10 is used. This is for the purpose of completely melting the base glaze 9 and 10 before the adhesive glaze 11 softens and melts. The fine particles 14 have a higher melting point than the adhesive glaze 11 (for example, 10◇
℃) and which is composed of fused alumina particles and/or zircon sand particles and has a particle size of 0.06IllI1 or more and less than 0.11. The reason why the melting point of the fine particles 14 is made higher than that of the adhesive glaze 11 is to form fine protrusions for anti-slip without melting the fine particles 14 during firing.

゛Fine particles 14 and adhesive glaze 1 constituting the suspension 15
The blending ratio of 1 is such that the value obtained by dividing the weight of the fine particles 14 by the dry weight of the adhesive glaze 11 is 0.2 to 0.4 (preferably 0.
3). Suspension 15 with this blending ratio is:
The specific gravity is adjusted to about 1.9 to 2.1. The suspension 15 may be applied by a known application method such as a spraying method using a machine or a centrifugal glazing machine, or a printing method using a screen printing machine.

In the fourth step, the base 16 obtained in the third step is coated with a base glaze 9.
．． 10 and the adhesive glaze 11 at a temperature T1 of 12 or higher and lower than the eutectic temperature of the adhesive glaze and the fine particles of 13, which is 13. When the base glaze 16 reaches the melting point T4 of the base glazes 9 and 10 as the temperature increases, the base glaze layer 13 melts, and when the eutectic temperature T2 is reached as the temperature increases, the base 16 becomes a thin adhesive. Glaze 11 is melted. However, even if the adhesive glaze 11 melts on the base glaze layer 13 in a molten state, the base glazes 9 and 10 have very poor fluidity, with a measured value of 1=2.0 co+ or less in the inclined button test. It does not flow into the base glaze layer 13 at all. Furthermore, since the upper limit of the firing temperature is less than the above-mentioned temperature 14, the fine particles 14° 14... do not melt at all and form the base glaze layer 1.
The adhesive glaze 11 melted on the adhesive glaze 11 is used to fix the adhesive.

Even if the fine particles 14 are covered with the adhesive glaze 11 during application in the third step (see FIG. 2(B)),
As the adhesive glaze 11 melts during firing, a portion thereof is exposed due to flow (see FIG. 3). After being maintained at the firing temperature T1 for an appropriate time, it is gradually cooled to obtain a non-slip tile 17 according to the present invention shown in FIG.

Note that the first layer 13 of the base glaze layer 13 shown in FIG. 2(B)
When the base glaze 9 forming a is bright glaze or semi-matte glaze, the base glaze 10 forming the second layer 13b is matte glaze, and the adhesive glaze 11 is matte glaze, a mosaic consisting of a glossy part and a matte part is created. It is possible to obtain an anti-slip tile with a pattern and excellent design effect.

The inventor conducted an experiment under the following conditions and obtained the following results.

As detailed above, the method for producing an anti-slip tile according to the present invention uses a base glaze that has a fluidity of 2.0 CIll or less as measured by the tilt button test, so that fine particles are absorbed into the base glaze layer. Furthermore, since a suspension of fine particles suspended in adhesive glaze is applied to the surface of the base glaze layer, the fine particles and adhesive glaze blend well, and the fine particles firmly adhere to the inner surface of the base glaze layer. Fix it. In addition, the anti-slip tile according to the present invention has a surface of the base glaze layer with 0.0610
Since microscopic protrusions are formed in which fine particles with a particle size of 1 or more and less than 0.1 ll1 are adhered and fixed via an adhesive glaze, it has a non-slip effect that can fully exhibit the anti-slip effect without causing any damage to bare feet. It is a stop tile.
