Abstract

The invention relates to a carbon fiber reinforced weather-proof PC / ASA composite material, which is composed of the following components in parts by mass: 30-60 parts of PC resin; 10 to 30 parts of ASA resin; 5-10 parts of an auxiliary agent bag; 0.2 to 0.6 part of an antioxidant; 0.3 to 0.9 part of a lubricant; and 20-40 parts of carbon fibers. The invention discloses the carbon fiber reinforcedweather-proof PC / ASA composite material, which is prepared by the following steps: mixing the raw materials according to the ratio, stirring at high speed for 3-5 minutes to obtain a mixture, addingthe mixture into a double-screw extruder, carrying out melt extrusion, adding the carbon fibers through side feeding, and carrying out mixing and granulation. The obtained material has the characteristics of good weather resistance, dimensional stability, impact resistance, warping resistance and excellent rigidity.

Description

[technical field] [0001] The invention belongs to the field of polymer materials, and in particular relates to a carbon fiber reinforced weather-resistant PC / ASA composite material and a preparation method thereof. [Background technique] [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. Polycarbonate is colorless and transparent, heat-resistant and impact-resistant. Polycarbonate has good impact resistance, high refractive index, and good processing performance. , but the wear resistance of polycarbonate is poor, and the use of polycarbonate devices for some wear-resistant applications will be limited. [0003] ASA resin is an impact-modified resin copolymerized from terpolymers such as styrene, acrylonitrile and PMMA rubber. It has good mechanical and physical properties. The structures of ASA and ABS are similar. They are both made of acrylonitrile and Composed of butadiene rubber, it retains the exc...
