Description

DETAILED DESCRIPTION OF THE INVENTION (a) The present invention relates to a non-slip surface treatment method for artificial stone.

(B) Conventional Technology Conventionally, in the building industry, a non-slip floor material for external or semi-external use is required.

As a processing method for this non-slip, a method of finishing the floor material surface of natural stone or artificial stone to a rough surface by shot blasting, jet burner, etc., or carving a groove or pattern on the floor material surface to prevent slipping etc. Is being processed.

In addition, there is a non-slip treatment in which a cement portion on the surface of an artificial stone is dissolved with an acid solution and then washed with water to form a rough surface by the exposed aggregate.

(C) Problems to be Solved by the Invention However, all of the above treatments have the drawback that the original texture of the material is impaired, and that they are particularly easily soiled and difficult to remove. .

For example, in the present situation, even if a water-polishing treatment is desirable to achieve the original texture of granite, the jet burner finish is inevitably used to prevent slipping.

In addition, there is a problem in that the surface is lost in gloss and the texture is lost and that the above-mentioned aggregate is granular, so that the anti-slip effect is weak if it is simply treated with an acidic liquid.

There is a method of forming a high-strength artificial stone floor material by centrifugal molding, but this method requires a centrifugal molding machine and requires a large amount of equipment. Since it takes time to manufacture, the manufacturing cost is high, and high strength is required. However, when strength is not required, there is a problem in cost.

(D) Means for Solving the Problems In the present invention, the surface of an artificial stone floor material in which acid-resistant aggregate and mortar are mixed is subjected to water polishing treatment to form a ridge angle on the periphery of the exposed surface of the aggregate. Then, the present invention provides a non-slip surface treatment method for artificial stone, which is characterized by corroding the surface with an acid solution.

(E) Action / Effect According to the present invention, the surface of the artificial stone is polished with water, that is, the surface of the artificial stone is polished with a grindstone or water resistant sandpaper, etc. while washing away the grinding dust with water. By doing so, the aggregate is exposed on the surface of the artificial stone, and moreover, by the water polishing treatment, a ridge angle is formed on the peripheral edge of the exposed surface of the aggregate.

By corroding the surface of the artificial stone that has been water-polished with an acid solution in this way, the mortar between the acid-resistant aggregates is removed and the aggregates become in a protruding state, exposing the aggregates. A strong anti-slip effect occurs due to the ridge angle of the peripheral edge of the surface.

Further, the exposed surface of the acid-resistant aggregate is kept in a glossy state that has been subjected to a water polishing treatment, and the exposed surface of the glossy aggregate and the surface of the corroded mortar are mixed. , You can get the surface of artificial stone with unique texture that is half-matt.

In addition, since the centrifugal molding method is not used to mold the artificial stone floor material, it does not require large-scale equipment such as a centrifugal molding machine. There is an effect that it can be manufactured.

In particular, the structure of the artificial stone flooring material of the present invention is not as dense as the structure of the centrifugally molded artificial stone flooring material, so that the corrosion by the acid solution progresses quickly, and the stains described above are hard to stain and the stains easily fall off. In addition, there is an effect that it is possible to form a surface having a unique half-matte texture and a non-slip effect in a short time.

(F) Example To explain the example of the present invention in detail with reference to the drawings, (A) shows an artificial stone floor material, and an acid-resistant aggregate (1) and a mortar produced from, for example, Portland cement or the like. An artificial stone floor material (A) is obtained by curing a slurry obtained by mixing (2) with a desired shape.

The particle size and the mixing ratio of the aggregate (1) are appropriately determined according to the texture and the like required for the artificial stone floor material (A) of the product.

The artificial stone floor material (A) thus formed has an acid-resistant aggregate (1) buried therein as shown in the cross-sectional view of FIG. The periphery is filled with mortar (2) without any gaps.

The surface (3) of the artificial stone floor material (A) is water-polished, that is, the surface of the artificial stone is smoothly polished with a grindstone or water-resistant sandpaper while washing away the grinding dust with water. As shown, the acid resistant aggregate (1) is exposed on the same surface (3).

Surface (3) of artificial stone flooring (A) that has been polished in this way
Shows that the aggregate (1) and the mortar (2) are almost in average, and the exposed surface (4) of the aggregate (1) is glossy by polishing with water. Is formed into a smooth surface, and a ridge angle (5) is formed on the peripheral edge of the exposed surface (4).

In this way, by treating the surface (3) of the artificial stone floor material (A) that has been subjected to the water polishing treatment with an acidic liquid, for example, 10% hydrochloric acid, the mortar (2) on the surface (3) is corroded. Since the aggregate (1) is acid-resistant, it remains without being corroded. As shown in FIG. 3, the exposed surface (4) of the aggregate (1) is the surface of the mortar (2). It becomes the surface (3) of the artificial stone floor material (A) in a state of protruding more than (3). Moreover, the ridge angle (5) formed on the peripheral edge of the exposed surface (4) of the aggregate (1) appears on the surface (3) of the artificial stone floor material (A), and causes a strong anti-skid action.

In addition, since the exposed surface (4) of the acid-resistant aggregate (1) is maintained in the state of the initial surface treatment, the texture of the material is not impaired and the artificial stone has a non-slip effect. The surface (3) of the floor material (A) can be obtained.

The corrosion depth of the mortar (2) with the acidic liquid can be adjusted by the acidity and amount of the acidic liquid.
