以丙烯腈-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。

With acrylonitrile-butadiene-styrene(ABS) as substrate resins,by adding styrene-N-phenylmaleimide-maleic anhydride terpolymer (AS-MS-NB) as heat retardancy,high heat resistant ABS masterbatch was prepared with different content of heat retardancy at 240-270 ℃ in a twin-screw extruder. Meanwhile,by adding 1,2-bis(pentabromophenyl)ethane(DBDPE) to the masterbatch,high heat resistant and flame retardant ABS was fabricated by twin-screw extruder at 180-210 ℃. The results show that,the fabricated high heat resistant and flame retardant ABS material both features high heat resistance and flame retardancy, at the same time, the heat resistance and its content have a positive correlation by this two-step method. Meanwhile, with the DBDPE, the masterbatch heat distortion temperature does not decrease remarkably,bending strength,tensile strength and impact strength decrease slightly,but fluidity improves obviously. The fabricated high heat resistant and flame retardant ABS can be widely applied to the motor,blower,power box,microwave ovens,rice cookers,connectors and so on.
