▎ 摘 要
NOVELTY - Method for preparing graphene-reinforced polypropylene composite material, involves melt blending 10-40 parts mass random copolymer polypropylene, 10-40 parts mass homopolymer polypropylene, 5-40 parts mass graphene and 3-23.5 parts mass processing additive to obtain the product. USE - The method is useful for preparing graphene-reinforced polypropylene composite material in a thermally conductive product (all claimed). ADVANTAGE - The composite material has excellent thermal conductivity and mechanical properties.
