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...
