Abstract

The invention discloses a highly-impact-resistant anti-static reinforced PC composite material. The highly-impact-resistant anti-static reinforced PC composite material is prepared from the following components in percentage by mass: 60%-90% of PC resin, 5%-10% of an impact-resistant modifier, 2%-5% of anti-static master batches, 5%-20% of a reinforcing agent, 2%-5% of a compatilizer, 0.1%-0.5% of an antioxidant and 0.1%-2% of a lubricant. Compared with the prior art, the PC composite material has the advantages such as high anti-impact efficiency, good tensile strength, high elongation at break, good gloss and mobility, and strong processing adaptation while keeping the excellent physical, chemical and electrical performances of PC. Moreover, the highly-impact-resistant anti-static reinforced PC composite material has excellent anti-static performance, has surface resistance of 10<8-10> ohm, and has good application prospect in the fields such as electronics, cars and mechanical parts.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high impact and antistatic reinforced PC composite material. Background technique [0002] Polycarbonate (PC), as a good performance and widely used engineering plastic, also has some defects, such as poor processing performance, easy stress cracking, notch impact and poor low temperature toughness, etc., and it is easy to generate static electricity, which greatly limits its application. Therefore, it is necessary to modify PC in order to further improve its performance and better adapt to market demand. Contents of the invention [0003] The purpose of the present invention is to provide a high impact and antistatic reinforced PC composite material. [0004] The technical solution adopted by the present invention to solve the technical problem is: high impact and antistatic reinforced PC composite material, its components are proportioned by mass percentage: PC ...
