Abstract

The invention discloses a thermal-conductive antistatic PC/ABS (polycarbonate/acrylonitrile butadiene styrene) material and a preparation method thereof. The PC/ABS material comprises the following compositions in percentage by weight: 30-50% of PC resin, 10-25% of ABS resin, 20-35% of thermal conductive powder, 10-20% of antistatic agent, 2.5-5.5% of a compatilizer, 4-7% of toughening agent, 0.1-0.5% of lubricant, 0.1-1% of antioxidant, and 0.1-1% of anti-ultraviolet agent, wherein the thermal conductive powder is treated by using a coupling agent. According to the PC/ABS material prepared in the invention, the thermal conductive powder is treated by using the coupling agent, and due to the mutually cooperated and coordinated action of the two fillers (namely, the thermal conductive powder and the antistatic agent), the high-performance thermal conductivity and antistatic property can be realized with less filling quantity; and the physical and mechanical properties of the prepared PC/ABS material are excellent.

Description
