Abstract

The invention discloses an antistatic ABS resin composition with improved chemical resistance and a preparation method thereof. The raw materials include the following components by weight: 80-93 parts of bulk method ABS resin, 4-13 parts of heat-resistant modifier, 3‑16 parts of nylon 56, 0.05‑2.0 parts of processing aids, 0.05‑2.0 parts of weather resistance additives, appropriate amount of color matching pigments. The raw materials are first premixed in a high-speed mixer, and then the premixed material is passed through a twin-screw extruder to obtain an antistatic ABS resin composition with improved chemical resistance. The antistatic ABS resin with improved chemical resistance provided by the present invention has high impact toughness, good high temperature resistance, excellent chemical resistance and antistatic properties, and is especially suitable for door panel stretching, seat armrests, and electrical connection protection shells In the interior and exterior decorations.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to an antistatic ABS resin composition with improved chemical resistance and a preparation method thereof. Background technique [0002] With the gradual advancement of the lightweight process of automobiles, the proportion of plastics and their products in automobiles is gradually increasing. Among them, ABS materials are widely used in automobiles because of their high strength, good toughness, easy processing and good gloss. Interior and exterior materials. ABS resin currently on the market is divided into two types of ABS resins, emulsion method and bulk method according to its production method. The ABS resin prepared by the emulsion method has relatively small rubber particle size, relatively high acrylonitrile content, and has good chemical resistance. However, its distributability is poor, and it is generally used for exterior painting parts; the bulk me...
