▎ 摘　　要

NOVELTY - Three-layer composite polypropylene antistatic material comprises two layers of antistatic layer and the middle layer between the two layers of antistatic layer. The raw material of the middle layer comprises polypropylene. The antistatic layer comprises 50-70 pts. wt. polypropylene, 15-25 pts. wt. carbon black, 8-12 pts. wt. carbon fiber, 3-7 pts. wt. graphene and 3-7 pts. wt. auxiliary agent. USE - The antistatic material is useful in chemical industry, agriculture, construction and manufacturing industry industries. ADVANTAGE - The antistatic material has excellent conductivity, good mechanical performance, anti-aging and corrosion resistance, and does not affect the processing performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the three-layer composite polypropylene antistatic material comprising (A) mixing the raw materials in the antistatic layer, extruding and granulating to obtain the antistatic layer granules and (B) performing the three-layer coextrusion to the antistatic layer granules and the middle layer of the raw material to obtain the three-layer composite polypropylene antistatic material.
