Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-slip tile and a method for manufacturing the same, and its purpose is to further increase the strength of the tile compared to conventional tiles, and to maintain the non-slip effect even after long-term use. An object of the present invention is to provide a completely new non-slip tile that does not reduce the number of slips and a method for producing the same.

Conventionally, hard particles were placed on the surface of flooring materials such as tiles and blocks to prevent slipping, for example,

Although this technique is known from publications such as JP-A-48-32662 and JP-A-53-78629, the adhesive strength is not perfect because the particles are bonded with an adhesive. This has the disadvantage that peeling occurs or wear occurs due to long-term use, reducing the anti-slip effect and shortening the service life.

In order to solve this drawback, the present applicant filed Utility Model Application No. 1983-62739 (Utility Model Publication No. 52-53570), which has already been registered. In other words, Jitsugan 49
The invention related to application No. 62739 forms grooves on the surface of the tile body made of ceramic clay such as feldspar, silica, clay, etc.
It is made by dispersing coarse particles of a hard material such as pottery stone and fixing them together by firing under pressure.In this design, the coarse particles of the hard material caused damage to manufacturing equipment such as molds and kneading machines during tile manufacturing. There is a risk that
Furthermore, if the particles are coarse, there is a possibility that the particles may expand after firing with respect to the tile body, resulting in a rough finish. Furthermore, in this invention, coarse particles of hard material are dispersed and fixed only to the surface of the tile body by pressure firing, so the coarse particles may peel off from the tile body, or the coarse particles on the surface may become hard due to long-term use. A fatal drawback was that the non-slip effect was reduced or eliminated due to wear. As a result, the non-slip tile had a short lifespan, making it unsuitable for long-term use. Another drawback was that it was extremely dangerous due to the coarse particles.

The present invention can solve all of the above problems, and is made by dispersing and firing fine particles of hard materials such as silicon carbide, crystalline alumina, and pottery stone throughout the tile body made of ceramic clay. To provide a non-slip tile and a method for manufacturing the same.

First, the specific structure of the non-slip tile of the present invention will be described below according to an embodiment shown in the drawings.

1 is a tile body made of ceramic clay 2 such as feldspar, silica, clay, etc., and 3 is fine particles that are uniformly dispersed throughout the tile body 1 and fired together with the tile body 1, and have a particle size of JIS.R6001. It is number 80 on the Mohs hardness scale, and consists of a crystalline alumina material (morundum) with a Mohs hardness of 12, a silicon carbide material (density) with a hardness of 13, and hard materials such as pottery stone.

As described above, in the present invention, the fine particles 3 made of a hard material are dispersed and fired almost uniformly throughout the tile body 1 to form the tile, so even if the surface particles are worn out by long-term use, the particles will remain intact throughout the tile body 1. Since the particles are dispersed, particles appear on the surface one after another, maintaining the non-slip effect. As a result, a completely new effect with sufficient durability to withstand long-term use was achieved. Furthermore, since the particles are fine particles, they are not dangerous and can be provided as extremely safe tiles.

Next, a method for manufacturing the above-mentioned non-slip tile will be explained with reference to FIG.

First, a ceramic clay 2 containing 20 to 30% water to make it relatively viscous and fine particles 3 of the hard material at a ratio of 10% to the ceramic clay 2 are put into a stirrer 4. Stir and knead well. Next, ceramic clay 2
and fine particles 3 from a stirrer 4 to a tube-like extruder 5.
Then, in the extruder 5, it is press-fitted into the next mold while being pressurized with a screw (not shown).

The material press-fitted into the mold 6 is fired at a temperature of 1000°C.
The tile body is formed into the desired shape by firing at a temperature of ~1300°C, then removed from the mold and allowed to harden naturally.
A non-slip tile is formed.

Since the present invention uses the above manufacturing method, the tile main body 1 itself can be strongly molded by high-temperature firing, and since fine particles 3 are used, the agitator 4, extruder 5, mold 6 There is no risk of the fine particles 3 being damaged, and there is no risk that the fine particles 3 will expand even after firing.

Furthermore, since the present invention is constructed by dispersing the fine particles 3 substantially uniformly throughout the tile body 1, the strength of the tile body 1 can be further increased, and reduction in the non-slip effect due to wear can be reliably prevented.

In addition, in the above example, the particle size of the fine particles 3 is
JIS.R6001 No. 80 is used, but it is by no means limited to this, and JIS.R6001 is preferably used.
R6001 with numbers 60 to 90 is good.

As mentioned above, the present invention is made by dispersing and firing fine particles of hard materials such as silicon carbide, crystalline alumina, and ceramic stone throughout the tile body, resulting in significantly increased strength and long-term durability compared to conventional tiles. The use of tile has a particularly remarkable effect in that even when the surface of the tile is worn, particles are always exposed on the surface and the non-slip effect is not diminished. As a result, it is possible to maintain a long service life without impairing the non-slip function, and there is a great practical benefit in that it is possible to provide a non-slip tile that has excellent durability and does not peel off during long-term use. Furthermore, in the present invention, since fine particles are used, the stirrer, mold, etc. are not damaged during the manufacturing process of kneading the fine particles and the ceramic clay.
There is a practical benefit in providing safe tiles without the dangers of tiles. In particular, even if the surface of the tile body is partially abraded, the fine particles are dispersed throughout the tile body, so the non-slip effect does not deteriorate, which is an exceptional advantage.
