Preparation method of self-cleaning composite artificial stone material

Abstract

The invention relates to a preparation method of a self-cleaning composite artificial stone material, and belongs to the technical field of building materials. The preparation method of the self-cleaning composite artificial stone material utilizes methyl methacrylate, polyurethane and polyethylene resin as raw materials, cobalt octoate as a catalyst, sodium silicate as a modifying agent and triethoxysilane as a coupling agent; a self-cleaning binder is synthesized; the self-cleaning capacity of a surface of an artificial stone material is increased; meanwhile, the wear-resistance capacity of the artificial stone material is increased; afterwards, building waste soil, bentonite and blast-furnace slag are used a mixture; micro-content metallic elements such as titanium and the like in the mixture are utilized as a pholocatalyst; the decomposition capability, to a pollutant, of the artificial stone material is increased; finally, the composite artificial stone material is made and obtained by vibration, extrusion and drying. The preparation method effectively solves problems that the surface of the artificial stone material is easily corroded after the surface of the artificial stone material is subjected to pollution treatment, and meanwhile, the surface of the artificial stone material loses a gloss after being washed; the effect of self-cleaning, without a washing agent for washing, of the artificial stone material is realized.

Description

technical field [0001] The invention relates to a preparation method of self-cleaning composite artificial stone, which belongs to the technical field of building materials. Background technique [0002] Artificial stone is a mineral-filled polymer composite material that is vacuum-cast or molded from natural ore powder, high-performance resin and natural pigments. It can be widely used in public buildings and home decoration. It is a non-radioactive pollution-free Environmentally friendly and green new building interior decoration materials that can be reused. [0003] According to the different binders used, artificial stone can be divided into two categories: inorganic artificial stone and resin artificial stone. Inorganic artificial stone has good weather resistance, non-combustibility, and low price, but the disadvantage is poor acid resistance. The gloss is low; the comprehensive performance of resin type artificial stone is better, but the production cost is high, th...

Problems solved by technology

[0005] The technical problem to be solved by the present invention: Aiming at the problem that the surface of artificial stone is easy to be corroded after being polluted in the traditional way, and the surface of artificial stone turns yellow and loses luster after cleaning, a self-cleaning composite artificial stone is provided The preparation method of the present invention uses methyl methacrylate, polyurethane and polyethylene resin as raw materials, cobalt octylate as a catalyst, sodium silicate as a modifier, and triethoxysilane as a coupling agent to synthesize a self-cleaning binder , to increase the self-cleaning ability of the surface of artificial stone, and at the same time increase the anti-wear ability of artificial stone, and then use construction slag, bentonite and blast furnace slag as a mixture, and use a small amount of metal elements such as titanium in the mixture as a photocatalyst to increase the wear resistance of artificial stone. The ability to decompose pollutants, and finally through vibration, extrusion, and drying, the composite artificial stone is obtained. The invention effectively solves the problem that the surface of the artificial stone is easily corroded after the surface of the artificial stone is polluted, and the surface of the artificial stone turns yellow after cleaning. The problem of tarnishing, realizes the self-cleaning effect of artificial stone without cleaning agent
