Abstract

The invention discloses a PC / ABS / nano carbon fiber blended composite material comprising the components by the mass percentage: 40%-70% of PC, 20%-40% of ABS, 5%-15% of nano carbon fiber, 3%-10% of SNA, 2%-5% of a compatilizer, 0.5%-3% of a stabilizer, 0.1%-0.5% of an antioxidant, and 0.1%-1% of a lubricating agent. The PC / ABS / nano carbon fiber blended composite material has the beneficial effects that the PC / ABS / nano carbon fiber blended composite material has the advantages of high strength, high hardness, high rigidity, good wear resistance, good electrical properties, low cost and the like, and has quite good application potential and broad prospects in automobiles, electronic and electrical appliances, machinery parts and components, instruments and meters, communications and other fields.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a blended composite material of PC / ABS / nano carbon fiber. Background technique [0002] Polycarbonate (PC) has excellent mechanical properties, heat resistance and dimensional stability; but PC has high melt viscosity, high processing temperature, difficult molding process, and is very sensitive to gaps, poor solvent performance, expensive, etc. , which limits its application in many fields. Co-alloying is an important method of PC modification, which can make PC performance more excellent and more widely used. Contents of the invention [0003] The purpose of the present invention is to provide a PC / ABS / nano-carbon fiber blended composite material with excellent mechanical properties. [0004] The technical solution adopted by the present invention to solve the technical problem is: a blended composite material of PC / ABS / carbon nanofiber, the components of which ar...
