Problems solved by technology

[0003] PC resin is polycarbonate resin, which can complement ABS resin to a certain extent. Although the two are made into PC / ABS alloy, the strengths and weaknesses have been improved, and better low-temperature impact performance, formability and heat distortion temperature have been obtained. Light stability, but the problem of wear resistance of PC / ABS alloys still needs to be solved

Abstract

The invention discloses a wear-resistant PC / ABS material and a preparation method thereof. The material comprises the following raw materials in parts by weight: 80-100 parts of PC, 20-30 parts of ABS, 1-3 parts of a wear-resistant agent, 1-2 parts of a filler, 1-2 parts of a lubricant and 1-3 parts of a compatilizer. The wear-resistant agent is obtained by the following steps: mixing rubber particles and glass fibers in a shearing machine at a high speed to obtain a mixture, and then extruding and granulating the mixture at the temperature of 230-280 DEG C to obtain the wear-resistant agent. According to the wear-resistant material, PC and ABS are combined, the wear-resistant agent is added, the wear resistance of the material is improved, and meanwhile, the overall performance of the material is improved through the filler.

Description

Technical field [0001] The present invention relates to a wear resistant PC / ABS material and a preparation method thereof, belonging to the field of plastic technology. Background technique [0002] PC / ABS alloy materials have a wide range of applications in automobiles, home appliances, communications, and IT industries, in recent years, in recent years, with the rapid development of the automotive industry and the development of plastic steel The trend has enabled PC / ABS alloy materials in the automotive industry.
