Problems solved by technology

The method of use is mainly to realize the dispersion of the antistatic agent in the ABS matrix through the twin-screw extrusion granulation method, but the twin-screw extrusion granulation method is a physical blending method, so the dispersion of the antistatic agent in the ABS matrix The effect is limited to a certain extent, so that the effect of the antistatic agent cannot be fully exerted

Abstract

A novel antistatic ABS composite material provided by the invention consists of 150 to 250 parts of acrylonitrile, 200 to 400 parts of butadiene, 400 to 600 parts of α-methylstyrene, and 10 to 30 parts of hydroxybutyrate It is prepared from base vinyl ether, 10-30 parts of vinyl acetate and 15-30 parts of initiator. The invention also discloses a method for preparing the composite material by adopting a novel monomer with an antistatic effect. The method mainly includes: firstly preparing two different latexes respectively, and then mixing the two latexes for copolymerization. After the polymerization reaction is completed, , purifying and drying the obtained antistatic ABS composite material to finally prepare the composite material, which has good antistatic performance.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to an antistatic ABS composite material and a preparation method. Background technique [0002] Acrylonitrile-butadiene-styrene (ABS) material is an insulating material. In some specific use environments, it is easy to accumulate static electricity and cause danger. In order to reduce or eliminate the harm caused by the accumulated charge to the ABS material during use, antistatic agents are often added to the ABS material to divert or eliminate the accumulated harmful charge in a timely manner. The antistatic agent reduces the resistivity of the ABS material by forming an ordered arrangement on the surface of the ABS material, or forming a charge-conducting network structure in the polymer matrix. [0003] Chen Erfan and others used a twin-screw extruder to prepare antistatic ABS alloy materials by extruding and granulating dimethylaminoethyl methacrylate b...
