Abstract

The invention relates to a preparation method of high-strength artificial stone, belonging to the technical field of artificial stone materials. According to the invention, styrene and waste rubber powder are mixed, ethyl acetate is adopted as a liquid physical foaming agent, composite particles prepared through extrusion granulation serve as a filler, high-alumina cement serves as a structural layer, and a carboxylic butadiene-styrene latex is added into the structural layer, so the high-strength artificial stone is prepared. A compounding ratio of the carboxylic butadiene-styrene latex and styrene is high, so adhesive force and film forming strength are high, mechanical and chemical stability is good, fluidity and storage stability are good, and a filling amount is large; by adding the carboxylic butadiene-styrene latex into the structural layer, the toughness, the compressive strength, the bending strength and the wear resistance of the artificial stone can be improved; and rubber particles play an enhancing role in an artificial stone system, so the impact strength and the plasticity of the artificial stone can be improved, and the larger rubber particles can prevent growth andbreakage of single crazes and improve the low-temperature flexibility of the artificial stone.

Description

technical field [0001] The invention relates to a preparation method of high-strength artificial stone, which belongs to the technical field of artificial stone materials. Background technique [0002] Artificial stone has bright colors, good machinability and uniform color. It is one of the main building decoration materials chosen by consumers. Moreover, it has rich raw materials, simple preparation process, excellent performance and low radioactivity, which makes up for the lack of natural stone resources and Some performance defects have broad development prospects. [0003] Artificial stone usually refers to a kind of building decoration material with natural stone texture, which is prepared under predetermined process conditions by using certain adhesives and adding coarse and fine fillers. In most cases, artificial stone is filled with calcium carbonate and silicon oxide. In addition, aluminum hydroxide, glass, ceramics, etc. can also be used as fillers according to ...
