Description
Technical field
The present invention relates to a kind of plastic material and preparation method thereof, relate in particular to a kind of antistatic ABS plastics and preparation method thereof.
Background technology
ABS resin (acrylonitrile-styrene-butadienecopolymer, ABS are the acronyms of Acrylonitrile Butadiene Styrene) is a kind of intensity height, good toughness, be easy to thermoplastics type's macromolecular material structure of machine-shaping.
ABS resin is vinyl cyanide, 1,3-butadiene and three kinds of monomeric graft copolymers of vinylbenzene.Its molecular formula can be written as (C
