Abstract

PURPOSE:To provide a type of uneven surface of tile not stained easily and permitting to relatively readily remove stains, in a tile having an anti-slip func tion produced by the formation of the uneven surface on the surface of the tile. CONSTITUTION:In a non-slip tile, on whose surface an uneven surface is formed so that the ten-point average roughness of the uneven surface is 25-200mum and that the lustering degree of the uneven surface is 5-20%. The non-slip tile can be produced by coating the surface of the substrate of the tile with a substrate- glazing agent having a heat-resistance of pyrometric cone equivalent of SK3a-11, further coating with an uneven surface-forming glazing agent having a pyrometric cone equivalent approximately the same as or higher than that of the substrate-glazing agent when the substrate-glazing layer is in a raw state, and subsequently sintering the coated tile substrate. By controlling the unevenness and the lustering degree of the surface of the tile substrate, a tile permitting the easy removal of sedimented dust is obtained without deteriorating the non-slip function.

Description of the Related Art Conventionally, as this non-slip tile, for example, as described in Japanese Patent Publication No. 60-39827, a glaze made of fused alumina whose melting temperature is higher than the firing temperature of the tile is applied to the surface of a ceramic tile. It is mixed and fixed to the tile, or a glaze with a high melt viscosity is applied to form an uneven surface, and the tile has a non-slip function.

Also, because it is hard to fall off, it looks conspicuous and gives a feeling of filth.

ものである。DISCLOSURE OF THE INVENTION An object of the present invention is to provide a tile which has an uneven surface on which a non-slip function is provided and which is less likely to be soiled and which can be relatively easily removed. This is intended to be found from the aspect of tile unevenness.

い。According to the present invention, the balance between the degree of unevenness that provides a non-slip function on the tile surface and the glossiness as an index of the ease with which dust or the like deposited on the tile surface can be removed. The optimum range is as follows: roughness of uneven surface is 10-point average roughness of 25 to 200 μm, preferably 50 to 150 μm.
And the gloss is 5 to 20%, preferably 8 to 1
The above problem was solved by setting it to 2%. Here, if the gloss level is less than 5%, it becomes difficult to remove stains, and if it exceeds 20%, it becomes slippery, which is not preferable.

することによって製造できる。In the non-slip tile having such surface irregularities, the tile base material surface is glazed with a base glaze having a fire resistance of SK3a to 11, and when the ground glaze layer is in a raw state, the fire resistance is a base. It can be produced by performing glaze treatment with a glaze for forming a textured surface that is higher than or equal to that of the glaze, and then firing.

が除去しやすいタイルが得られる。The function of preventing slippage of the tile surface, in particular, the function of preventing slippage of a normal tile with bare feet is uniquely related to the degree of unevenness formed on the tile surface. .. Further, the generation of stains and the ease of removal from the surface have a unique relationship with the degree of gloss. By defining this uneven surface in a range of 25 to 200 μm with a 10-point average roughness and a gloss level of 5 to 20%, accumulated dust can be removed without impairing the slip prevention function. You can get easy tiles.
