Abstract

The invention discloses a modified ABS antistatic material and a preparation method thereof. The antistatic material is formed by melting the mixture in an injection machine after mixing PEEA, maleic anhydride grafted ABS resin (or styrene maleic anhydride copolymer SMA), ABS resin, zlnc oxide whisker, coupler and other additives according to a given proportion. The antistatic ABS material has the advantages of low surface resistance, permanent static resistance, light color and good mechanics performance; and moreover, the antistatic ABS material has appropriate cost, no toxicity and pollution, simple formation processing technology, easy realization and promising application prospect.

Description

technical field [0001] The invention relates to an ABS antistatic material and a preparation method thereof, and belongs to the field of modification, processing and application of ABS resin materials. Background technique [0002] ABS resin is a thermoplastic made by copolymerizing three monomers of styrene (St), butadiene (Bd) and acrylonitrile (AN). ABS resin has excellent comprehensive performance, excellent impact performance, good dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, good molding and mechanical processing. However, due to its molecular structure, it is a poor conductor of electricity, and it is easy to accumulate static charge during processing and use. When the static charge accumulates to a certain extent, static electricity will cause the material to absorb dust, cause material damage, and may also generate static spark discharge. , causing chemical product warehouses to explode and catch fire, resulting in...
