Abstract

The invention relates to a polycarbonate/ABS resin plastic alloy to mainly solve a problem of low impact strength of polycarbonate/ABS plastic alloys prepared through previous technologies. The problem is well solved through adopting a technical scheme that the plastic alloy is composed of a polycarbonate resin, a bulk polymerization ABS resin, a compatilizer SMA resin, and auxiliary agents of an antioxidant and the like in the invention. The polycarbonate/ABS plastic alloy can be applied to the production of various plastic products needing the high impact strength, such as automobile bumpers, meter panels and the like.

Description

technical field [0001] The invention relates to a polycarbonate / ABS resin plastic alloy. Background technique [0002] Polycarbonate resin is a kind of engineering plastic with excellent performance. It has the highest impact strength among all resins (Izod notched impact strength of 3.17mm thick sample reaches 800-1000J / m) and high heat resistance and transparency. , electrical insulation and dimensional stability, but its high melt viscosity limits its application as injection molding products: the processing temperature is high, and it is difficult to inject large-scale products; High stress, prone to stress cracking. ABS resin is a copolymer or blend of acrylonitrile-styrene-diene rubber, which has the characteristics of easy molding and processing, stable size, and good stress crack resistance. Blending polycarbonate resin and ABS resin to make PC / ABS plastic alloy can well solve the above-mentioned shortcomings of polycarbonate resin, and at the same time have high h...
