高性能低VOC环保PC／ABS合金材料的制备

摘要

以聚碳酸酯(PC)、丙烯腈–丁二烯–苯乙烯塑料(ABS)为基体树脂，加入聚烯烃弹性体(POE)、抗氧剂及其它助剂共混挤出造粒，制成低挥发性有机化合物(VOC)的环保PC／ABS合金材料。在用增韧剂POE及抗氧剂对PC／ABS体系进行改性的同时，探讨PC／ABS基料、增韧剂、抗氧剂对PC／ABS合金的力学性能、VOC及气味等级的影响，从而得到具有高性能、低VOC、低气味的环保PC／ABS合金材料，以期在汽车内饰件等方面得到应用。%Based on polycarbonate (PC),acrylonitrile–butadiene–styrene plastic (ABS) as matrix resin,by adding polyolefin elastomer (POE),antioxidants and other additives blended extrusion granulation,low-volatile organic compounds (VOC) PC/ABS alloy material which is always be friendly to environment was made. With toughening POE and antioxidants for PC/ABS system modified,the impact of PC/ABS binder,plasticizer,antioxidant on mechanical properties,VOC and odor level of PC/ABS alloys was explored. Thereby,a high-performance low-VOC PC/ABS alloy material was obtained in order to get application in the automotive interior.
