Problems solved by technology

[0003] Due to the low surface hardness of ordinary ABS products compared with some plastic products, its application in some fields is limited. Although there are other types of resins on the market with ideal surface hardness, these resins have improved surface hardness on the one hand and at the same time Other mechanical properties are reduced, on the other hand, the price is expensive, resulting in an increase in product cost

Abstract

This invention relates to flame-retardant modified ABS resin with high surface hardness. The modified ABS resin comprises: ABS 70-90 parts, glass microbeads 4-12 parts, epoxy resin 1-5 parts, compatibilizer 1-5 parts, bromine series flame retardant 1-9 parts, stibium series flame retardant 0.4-3 parts, and coupler 0.2-0.8 part. This invention improves the surface hardness and flame retardancy of ABS resin by adding flame retardants and reinforcer during blending, and retains the excellent physicochemical properties of ABS resin, thus expanding the industrial application range of ABS resin.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant ABS modified resin with high surface hardness. Background technique [0002] ABS (Acrylonitrile Butadiene Styrene) refers to a terpolymer composed of acrylonitrile, butadiene and styrene. Because ABS has good molding processability, the surface finish of the product is high, and it has good coating and dyeing properties. It can be electroplated into a variety of colors, coupled with excellent performance, reasonable price and easy processing and molding, it has become the thermoplastic engineering plastic with the highest output and the widest application. industry. [0003] Due to the low surface hardness of ordinary ABS products compared with some plastic products, its application in some fields is limited. Although there are other types of resins on the market with ideal surface hardness, these resins have improved surface hardness on the one hand ...
