一种高效抗静电PC/ASA合金及其制备方法
摘要：
本发明涉及一种高效抗静电PC/ASA合金及其制备方法，该PC/ASA合金包括以下组分以及重量份的原料制成：PC树脂50-90wt％，ASA树脂5-20wt％，SAN树脂0-10wt％，增韧剂1-5wt％，抗静电剂5-20wt％，离子液体2-10wt％，抗氧剂0.1-1wt％，润滑剂0.1-2wt％。将上述原材料在高速混合机中预混3-10min，然后将预混料加入到双螺杆挤出机中，在230-270℃下熔融挤出，螺杆机转速为300-500rpm，冷却造粒即得产品。与现有技术相比，本发明的优点是：利用咪唑类的离子液体和抗静电剂之间的协同作用从而大大提高PC/ASA合金的抗静电性能性，从而减少抗静电剂的使用节约生产成本。
摘要（英）：

The invention relates to an efficient antistatic PC/ASA alloy and a preparation method thereof. The PC/ASA alloy comprises the following raw materials in percentage by weight: 50-90wt% of PC resin, 5-20wt% of ASA resin, 0-10wt% of SAN resin, 1-5wt% of a toughening agent, 5-20wt% of an antistatic agent, 2-10wt% of ionic liquid, 0.1-1wt% of an antioxidant and 0.1-2wt% of a lubricant. The preparation method comprises the following steps: premixing the raw materials in a high-speed mixer for 3-10 minutes; adding the premix into a twin-screw extruder for melt extrusion at the temperature of 230-270 DEG C at the rotation speed of 300-500rpm; and cooling and granulating to obtain the product. Compared with the prior art, the PC/ASA alloy and the preparation method thereof provided by the invention have the advantages that the antistatic performance of the PC/ASA alloy is greatly improved by use of the synergistic effect between the imidazole ionic liquid and the antistatic agent, thus the use of the antistatic agent is reduced and the production cost is saved.
