2、丙烯腈–丁二烯–苯乙烯塑料(ABS)为基体,以苯乙烯–N–苯基马来酰亚胺–马来酸酐三元共聚物(AS–MS–NB)为耐热剂,在双螺杆挤出机中,于240~270℃制备出不同耐热剂含量的高耐热ABS母粒。以此母粒和十溴二苯乙烷(DBDPE)阻燃体系共混,于180~210℃通过双螺杆挤出机制备出高耐热阻燃ABS。结果表明,通过这种两步法制备的高耐热阻燃ABS材料兼具高耐热和阻燃特性,并且耐热剂含量和其制备的阻燃ABS材料的耐热性具有正相关性。同时加入DBDPE未使高耐热阻燃ABS的热变形温度明显降低,弯曲强度、拉伸强度及冲
3、击强度稍有下降,而流动性明显改善,高耐热阻燃ABS可广泛应用于电机、吹风机、电源盒、微波炉、电饭煲、插排等领域。关键词:耐热;阻燃;母粒;流动性;丙烯腈–丁二烯–苯乙烯塑料中图分类号:TQ325文献标识码:A文章编号:1001-3539(2013)11-0025-06PreparationandPropertiesofHighHeatResistantandFlameRetardantABS1,23221WangLulin,JiaoQian,WangLin,ZhengYiquan,MaiKancheng(1.Nat
