▎ 摘　　要

NOVELTY - Graphene modified heat-conducting plastic comprises 80-90% plastic base material, and 10-20% graphene, and having bulk density of 0.15-0.3 g/ml. USE - Graphene modified heat-conducting plastic. ADVANTAGE - The plastic has good heat-conducting property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene modified heat-conducting plastic comprising: (A) acidifying natural graphite flake, adding strong oxidizing intercalation agent into natural graphite layer, forming hydrate, reacting at 800-1200 degrees C, gasifying, and forming vermiform graphite; (B) passing vermiform graphite through rolling to obtain thickness of less than or equal to 1 mm, with density of natural graphite strip of 1 g/ml, and processing to obtain low density of graphite powder of less than or equal to 0.15 g/ml; and (C) carrying-out mold pressing block treatment to obtain graphite block with density of greater than or equal to 1.5 g/ml, crushing, putting high density graphite powder and plastic base material to double screw pelletizer, mixing, and obtaining graphene modified heat-conducting plastic.
