Problems solved by technology

However, PC / ABS is a partially compatible polymer alloy, and its compatibility is not very good, resulting in insufficient toughness and poor wear resistance, and although the flame retardancy of PC itself can reach UL94 V-2, However, the addition of ABS reduces the flame retardancy of PC, and practical applications often require higher flame retardancy

Abstract

The invention discloses a flame retardant PC / ABS alloy having excellent wear resistance. The flame retardant PC / ABS alloy comprises the components by the mass percentage: 40%-75% of PC, 15%-30% of ABS, 3%-8% of a toughening agent, 5%-10% of a flame retardant agent, 2%-5% of nano-fumed silica, 1%-3% of a wear-resisting agent, 0.5%-2% of a stabilizer, 0.5%-3% of a compatilizer, 0.1%-0.5% of an antioxidant, and 0.1%-1% of a lubricant. The flame retardant PC / ABS alloy has the beneficial effects that while having both PC and ABS advantages, the flame retardant PC / ABS alloy has excellent wear resistance and flame retardant property, also maintains good mechanical, chemical and electrical properties, has good processing properties, is low in cost, and has quite high practical values and broad application prospects in automobiles, electronic and electrical appliances, mechanical equipment, instruments and meters, communications and other aspects.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant PC / ABS alloy with excellent wear resistance. Background technique [0002] PC / ABS alloy (polycarbonate / acrylonitrile-butadiene-styrene copolymer) is an important engineering plastic. It has the advantages of both PC and ABS. On the one hand, it can reduce the melt viscosity of PC. On the one hand, it improves the heat resistance and tensile strength of ABS, reduces the sensitivity of product internal stress and impact strength to product thickness, and has excellent heat resistance and mechanical properties. At present, PC / ABS alloys have been widely used in the automotive industry, electrical and electronic, office machinery, home appliances, communications and other departments. However, PC / ABS is a partially compatible polymer alloy, and its compatibility is not very good, resulting in insufficient toughness and poor wear resistance, and although t...
