Abstract

The invention belongs to the technical field of composite materials and specifically relates to an antistatic composite material. The antistatic composite material comprises, by weight, 40 parts of a polyethylene-acetic ether copolymer, 10-35 parts of conducting particles, 0.01-0.3 part of a coupling agent, 1-6 parts of an antioxidant and 20-35 parts of polyphenylene sulfide PPS. The conducting particles are core-shell structured particles formed by ferric oxide / silver. By addition of the core-shell nano-structured conducting particles, the prepared composite material has good antistatic property, and electro-discharge damage of electrostatic accumulation due to existing packaging to various sensitive electronic components and instruments and apparatuses, etc. can be solved. By the utilization of the conducting particles uniformly distributed in the film, conductivity is increased, electrostatic accumulation is reduced, and the problem of damage of static electricity to packaged goods is solved. The antistatic composite material has extensive significance in promotion and use.

Description

Technical field [0001] The invention belongs to the technical field of composite materials, and specifically relates to an antistatic composite material and a preparation method thereof. Background technique [0002] The surface resistivity of conventional plastic materials is relatively high (more than 10 12 Ω) is an insulating material. When this type of material is used as the coating material of electronic products, a large amount of high-voltage static electricity is often generated on the surface of plastic materials. When this high-voltage static electricity is improperly treated, electrostatic discharge can destroy electronic components and change semiconductor elements. The electrical performance of the device destroys the electronic system, causing the entire equipment to malfunction or malfunction; at the same time, static sparks are generated when the electrostatic charge is released, which is very easy to ignite flammable and explosive materials, causing great danger ...
