增韧耐热ABS组合物及其制备方法
技术领域
本发明属于高分子材料技术领域，具体涉及一种增韧耐热ABS组合物及其制备方法。
背景技术
ABS的性能介于通用塑料与工程塑料之间，具有很好的成型性，加工出的产品表面光洁，此外，还具有较高的冲击强度和较好的化学稳定性，但其耐热性和韧性均较差。
目前国产的耐热ABS树脂的性能仍较差，还需进一步改善，因此如何提高ABS的综合性能成为该领域亟待解决的技术难题。
发明内容
本发明的目的在于克服现有技术的不足而提供一种增韧耐热ABS组合物及其制备方法，本发明成品具有良好的耐热性和韧性，且力学性能优异。

所述抗氧剂为2,4-二(正辛基硫亚甲基)-6-甲基苯酚。
本发明的制备方法：将ABS树脂、烯丙基苯酚或双烯丙基双酚A改性双马来酰亚胺树脂、环氧树脂按照所述配比加入高混机中混料均匀，于190-195℃下挤出造粒，将粒料冷却至30℃，干燥后按照配比称取粒料、抗氧剂、碳纤维于高混机中混料，经双螺杆挤出机挤出，温度210-218℃，经造粒即可得本发明成品。
有益效果：本发明将所述各组分复配，在各组分共同作用下，具有良好的耐热性，热变形温度可达120℃，韧性良好，成品的冲击强度可达35 kJ/m2，拉伸强度较高可达65MPa。本发明制备方法简单易行，操作简单，可广泛推广。
