Properties and Structure of Recycled PC/Recycled ABS Blend System
Processed recycled PC and recycled ABS blended by vane extruder,analyzed the processing character of vane extruder and its impact on blends.The influence of three compatilizers to the compatibility, mechanical properties, thermal transition temperature, melt flow rate and morphological structure of recycled PC and recycled ABS blend was studied,including styrene/maleic anhydride copolymer (SMA-700),styrene/acrylonitrile/maleic anhydride terpolymer (SMA-800) and grafting maleic anhydride ABS (ABS-g-MAH).The results showed that the vane extruder made the recycled ABS phase dispersed more uniformly and the compatibility of blend systems was improved by three compatilizers.Meanwhile,the interfacial adhesion and the properties of the blend systems were enhanced.The optimum content of three compatilizers in blend were 6 ％ 、2 ％ 、6 ％ respectively.
