Abstract

The invention discloses a PC (polycarbonate) / ABS (acrylonitrile butadiene styrene) composition with an ESD (electro-static discharge) function and application thereof. The PC / ABS composition with the ESD function is prepared from the following components: PC resin, ABS resin, carbon fibers, carbon nanotubes, a toughening agent and other auxiliaries, the length distribution of the carbon fibers comprises the following components in percentage by weight: 30-40% of carbon fibers with the particle size of less than 120 microns (not including 120 microns), 15-25% of carbon fibers with the particle size of 120-180 microns, 30-40% of carbon fibers with the particle size of 180-350 microns (not including 180 microns) and 5-15% of carbon fibers with the particle size of more than 350 microns (not including 350 microns). The PC / ABS composition with the ESD function is prepared through the synergistic effect of the carbon fibers with specific length distribution and the carbon nanotubes with a very small addition amount, the melt viscosity is proper, and the surface has low floating fibers.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more particularly, to a PC / ABS composition with ESD function and its application. Background technique [0002] PC / ABS is one of the most widely used plastic alloys with excellent comprehensive properties. PC / ABS alloy has the advantages of both PC and ABS: it has high heat resistance, dimensional stability and mechanical properties of PC, and compared with pure PC, PC / ABS alloy has low melt viscosity and processing fluidity. It is good, the price is lower, and it also has the advantages of lower internal stress and lower notch impact sensitivity. [0003] However, PC / ABS alloy has poor electrostatic discharge (ESD) performance and high surface resistivity. In scenarios with high ESD requirements, such as home appliances, automobiles, construction, office supplies, etc. Add conductive additives, such as conductive carbon black, carbon fiber or carbon nanotubes. However, the intro...
