Abstract

The invention provides an abrasion-resistant high-flame-retardance PC material. The abrasion-resistant high-flame-retardance PC material is prepared from, by weight, 70-80 parts of PC, 5-12 parts of glass fibers, 1-5 parts of flexibilizer, 5-8 parts of compatilizer, 3-5 parts of abrasion-resistant agent, 0.1-1 part of coupling agent, 0.1-1 part of anti-dripping agent, 0.1-1 part of flame retardant, 0.2-2 parts of antioxygen, 0.2-2 parts of ultraviolet light absorber and 0.2-2 parts of lubricant. The invention further provides a preparation method of the abrasion-resistant high-flame-retardance PC material. The PC material has good abrasion resistance, high flame retardance and excellent mechanical performance; the PC material is low in cost, high in cost performance, simple in production technological process, easy to implement, free of environmental pollution and small in harm to human health.

Description

technical field [0001] The invention relates to the technical field of polymer modification, in particular to a wear-resistant and highly flame-retardant PC material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is an engineering plastic with superior comprehensive performance, and it is also the fastest-growing general-purpose engineering plastic this year. It has excellent impact toughness, weather resistance, and electrical insulation. It is widely used in automobiles, electronics, etc. , construction, equipment and other fields. But it also has some disadvantages, such as poor processing fluidity, prone to stress cracking, sensitive to notches, easy to absorb water, and poor wear resistance. Glass fiber has the characteristics of high tensile strength, high elastic coefficient, large impact energy absorption, good chemical resistance, low water absorption, good heat resistance, and low price. The combination of the two can form a go...
