一种低气味、高性能、高光泽PC‑ASA共混材料及其制备方法
摘要：
本发明公开了一种低气味、高性能、高光泽PC‑ASA共混材料及其制备方法，包括以下重量百分比计的原料：聚碳酸酯(PC)：20‑80％，丙烯晴‑苯乙烯接枝共聚物：10‑55％，丙烯腈‑苯乙烯‑丙烯酸酯接枝共聚物ASA：5‑35％，相容剂：2‑15％，除味剂：0.2‑2％,高光色母1‑5％。将经混合的原料置于螺杆直径35mm，长径比L/D＝36为双螺杆挤出机主机筒中，主机筒从加料口至机头出口分九段控制温度，依次为200℃、230℃、255℃、255℃、255℃、255℃、255℃、255℃、240℃，双螺杆转速为300转/分钟，挤出料条经过水槽冷却后切粒得到产品。由本发明方案得到的PC/ASA共混材料制成的汽车内饰件制品，具有低气味、高性能、高光泽，耐候性好等优点，可广泛应用于汽车内饰件。
摘要（英）：

The invention discloses a low-smell, high-performance and high-gloss PC-ASA blended material and a preparation method thereof. The low-smell, high-performance and high-gloss PC-ASA blended material comprises, by weight percentage, 20-80% of polycarbonate (PC), 10-55% of acrylonitrile-styrene grafted copolymer, 5-35% of acrylonitrile-styrene-acrylate grafted copolymer ASA, 2-15% of compatibilizer, 0.2-2% of deodorant and 1-5% of high-gloss color master batch. The preparation method is characterized in that the mixed raw materials are placed into a double-screw extruder main cylinder whose screw diameter is 35mm and length/diameter ratio L/D is 3, the control temperatures of the main cylinder from the head to an outlet are sequentially 200 DEG C, 230 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C, 255 DEG C and 240 DEG C, the rotation speed of double screws is 300r/minute, and extruded material strips are cooled by a cooling machine and diced to obtain the low-smell, high-performance and high-gloss PC-ASA blended material. Car interior trim parts produced by the low-smell, high-performance and high-gloss PC-ASA blended material are low in smell, high in performance, high in gloss, good in weather resistance, and the like, and the low-smell, high-performance and high-gloss PC-ASA blended material is widely applicable to the car interior trim parts.
