Problems solved by technology

[0003] However, compared with ordinary PC materials, ABS has poor heat resistance and low heat distortion temperature. The introduction of ABS materials will inevitably lead to a decrease in the heat resistance of the material, which limits its application. At present, it is mainly through the blending system Add heat-resistant additives such as maleimide copolymer and N-phenylmaleimide to improve its heat resistance, but it often requires a large amount of addition to play a role, and often leads to deterioration of other properties of the material

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a heat-resistant PC / ABS alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is widely used in various fields of social life such as electronic appliances, building materials, packaging, and automobile industry because of its excellent physical and mechanical properties, high impact strength, good electrical properties, and good dimensional stability. One of the polymers with the largest output and widest application at present. However, the viscosity of polycarbonate melt is high, molding processing is difficult, the internal stress of the product is large, and it is sensitive to the gap. At present, the most common method is to combine it with acrylonitrile-butadiene-styrene (ABS) ) to improve this problem. Due to its excellent physical and mechanical properties, PC / ABS alloy has been widely used in electronic communication...
