Description of the Invention: [Technical Field] The present invention relates to a floor tile having a projection for preventing slip and a method of manufacturing the same. [Prior Art] A floor tile having a convex portion on its surface for the purpose of slip prevention is described below. Φ Japanese Patent Laid-Open No. Hei 5 - 1 05 5 5 9 describes a slip-proof tile, as shown in Fig. 2, which forms a glaze layer 5 on the surface of the tile body 4, and at the same time makes a grain from the surface of the glaze layer 5. A part of the hard particles 6 having a diameter of 50 to 300 μm is protruded. The hard particles 6 are made of alumina, chrome or the like, and are disposed in an amount of about 1 to 40 per 1 cm 2 on the surface of the ceramic tile. The anti-slip tile is glazed on the surface of the green body or the calcined body, and then the hard particles are dispersed, and then fired to sinter the body, and the glaze is welded to the body, and the lower half of the hard particles are made. The side is not immersed in the glaze layer. ❹ 特 特 53 53 53-78629, page 2, the lower left column, the first row, the lower right column, the fifth row, also describes the sliding tiles with the same tiny protrusions. Manufacturing method. In particular, in the lower left column 15 to 16 of the second page of the document, as shown in Fig. 3, the green body 7 and the first glaze layer 9a on the green body 7 and the first glaze layer are described. The hard particles 8 on 9a and the second glaze layer 9b provided in such a manner as to cover the hard particles 8 are slip-resistant. A minute projection is formed on the surface of the second glaze layer 9b by the presence of the hard particles 8'. In the fifth row of the lower left column of the third page of the document, the prominent degree of the projection of the minute projection -5 - 201020378 is 0.1 to 〇.7 mm. Further, in the fifth drawing of the document, it is described that the drawing is based on the minute projections. As shown in Fig. 4, Japanese Patent Laid-Open No. 61-242256 describes a slip-resistant ceramic tile having a ceramic tile body 10, a concavo-convex pattern 11 thereon, and a matte glaze 12 covering the same. In the lower left column 4 to 5 of the second page of the document, the height of the unevenness is described as 〇3 mm or more, preferably 〇5 to 2.0 mm. In Japanese Patent Laid-Open No. 2000-109384, as shown in Fig. 5, it is described that a slight concavity 15 is provided on the glaze layer 14 on the surface of the @tile body 13 by ink. In paragraph 0 004 of the document, the height of the concavities and convexities is 30 to 1 ΟΟμιη > the interval is 200 to 400 μm η. In the case of a slip-slip tile formed by spreading hard particles and burning them, the hard particles are Condensation is concentrated between the particles, and it is easy to accumulate dirt between the particles. In general, if the anti-slip convex portion is increased, the anti-slip effect is improved, but the tile is likely to adhere to the dirt. Especially in buildings where shoes are worn, 入口 entrances or halls, etc., dirt adhesion is more noticeable. Further, in the case of a polished tile having a honed surface, if the number of the convex projections is increased and the area is increased, the degree of beauty of the polished surface is lowered. SUMMARY OF THE INVENTION An object of the present invention is to provide a floor tile which is not easy to slip even when wearing a shoe, and which is difficult to adhere to dirt, and a method of manufacturing the same. -6 - 201020378 The floor tile of the present invention is a floor tile provided with a convex portion for preventing slip on the surface, characterized in that the height of the convex portion is 0.1 to 1 mm, and the area of the base portion of the convex portion is 0.28 to 50 mm 2 , and adjacent thereto The average distance between the most recent convex portions is 1 to 10 mm. The floor tiles of the present invention are provided by widening the intervals between the convex portions, and the anti-slip effect is improved when applied to the ground on which the shoes are worn. And it is not easy to adhere to dirt. In addition, the convex portion and the surrounding floor tile have the same color system Φ, so the convex portion is not conspicuous and is very beautiful. The arrangement density of the convex portions of the tile is preferably 1 to 1 inch/cm 2 . The convex portion of the floor tile is the same color as the surface of the floor tile surrounding it. Preferably, the surface of the tile other than the convex portion of the tile forms an abrasive surface. The honing surface is both beautiful and can be prevented from slipping by the projections. In one aspect of the invention, the tile is a glazed tile, and includes: a tile body, and a glaze layer disposed on the surface of the porcelain body and having a surface honed, and a surface fused to the glaze layer The glaze of the glaze layer is the above-mentioned convex portion formed by the glaze Φ of low melting point. The tiles are aesthetically pleasing and the lobes are very strong and durable. The floor tile of this form is an unprocessed tile having a ceramic tile body and a glazed layer provided on the surface of the ceramic tile body, and is embossed on the surface of the glazed layer to form a convex glaze. Then, the printed glaze is fired in a manner of being burned on the glaze layer. In another aspect, the floor tile is an unglazed unglazed tile having: a tile body honed on the surface of the tile body, and a surface welded to the tile body body and having a lower melting temperature than the tile body. The above-mentioned convex 201020378 part made of glaze. The tiles are aesthetically pleasing, and the bumps are very strong and durable. The floor tile of this form is an unglazed unprocessed tile made of a ceramic tile body honed by a surface, and the glaze for forming a convex portion is printed on the surface of the honed tile blank body, and then The printed glaze is fired in the form of a ceramic tile and fired.

In this embodiment, the glaze layer 2 is not provided, and the surface of the tile blank ία is honed, and the convex portion 3 formed of the glaze is welded to the surface. The glaze in this case is a glaze having a melting point lower than the sintering temperature of the tile body 1 程度 to the extent that the firing of the convex portion 3 does not cause shrinkage of the tile body 1 烧. . e [Detailed Description of the Projection Portion 3] In the first and second embodiments, the height t of the convex portion 3 is 0.1 to 1 mm, preferably 0.2 to 〇..5 mm.

The floor tile has the unique smoothness and luster of polished tiles, which is very beautiful. The friction characteristics of the surface of the tile were measured as follows. The water was spread on the tile to be measured, and the heel portion of the male shoe was used as a measuring piece, which was placed on the tile, and a load corresponding to a weight of 80 kg was applied to the measuring piece vertically on the measuring piece. A certain speed is pulled in the horizontal direction, and the load required to be pulled in the horizontal direction at this time is measured, and the number 値 divided by the load applied in the vertical direction of the measuring piece is used as the friction coefficient. The larger the friction coefficient is, the larger the frictional resistance is, and the tile is less likely to slip. The smaller the friction coefficient is, the smaller the frictional resistance is, and the tile is more slippery. When the floor tile of Example 1 was measured by this method, the coefficient of friction was 0.76.
