以上所述的PC/AES合金材料,润滑剂为季戊四醇硬脂酸酯。
一种权利要求1所述PC/AES合金材料的制备方法,包括以下步骤:
1)按上述的重量百分比称取原料;
2)将步骤1)中称取的原料混合3-7分钟;
3)将步骤2)中混好的原料投置于双螺杆挤出机中经过熔融挤出,造粒;生产工艺条件为:双螺杆挤出机一区温度为200-220℃,二区温度为220-240℃,三区温度为220-240℃,四区温度为200-220℃,混合料在螺杆中输送时间为1-2分钟。
本发明的PC/AES合金材料综合了PC和AES材料的各自优点,使材料具有优异的综合力学性能和耐候性,能够用于建筑材料,通讯设备外壳,汽车零部件等户外耐候要求高的产品。
