Abstract

The invention relates to a low temperature impact resistant polycarbonate / ABS resin plastic alloy to mainly solve a problem that polycarbonate / ABS plastic alloys prepared through previous technologies have low temperature impact strengths and cannot satisfy some low temperature application requirements. The problem is well solved through a technical scheme that the plastic alloy comprises a polycarbonate resin with an appropriate molecular weight, a bulk polymerization ABS resin, an emulsion polymerization ABS resin, a compatilizer SMA resin, and auxiliary agents of an antioxidant and the like in the invention. The polycarbonate / ABS resin plastic alloy is especially suitable for the production of some low temperature application plastic products.

Description

technical field [0001] The invention relates to a low-temperature impact-resistant polycarbonate / ABS resin plastic alloy. Background technique [0002] Polycarbonate resin is an engineering plastic with excellent performance. It has the highest impact strength (at 3.17mm) and high heat resistance, transparency, electrical insulation and dimensional stability of all resins, 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; at the same time, because the polymer molecular structure is rigid, the melt viscosity is high, the internal stress of the product is large, and stress cracking is easy to occur. 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 polycarbonate / ABS resin plasti...
