▎ 摘　　要

NOVELTY - A thermally conductive graphene composite rubber comprises 1-10 mass% graphene, polymer matrix, coupling agent, and dispersant in which graphene is monoisotopic carbon graphene. USE - A thermally conductive graphene composite rubber (claimed). ADVANTAGE - Rubber has high quality and excellent thermal conductivity and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of thermally conductive graphene composite rubber which involves adding monoisotopic carbon graphene powder and coupling agent into high-speed mixer, uniformly mixing at 50-120 degrees C, activating monoisotopic carbon graphene surface, transferring into twin-screw extruder, adding polymer matrix and dispersant, mixing, dispersing at 100-200 degrees C, uniformly mixing, extruding, and granulating. DESCRIPTION OF DRAWING(S) - The drawing shows a process flow diagram of prepared thermally conductive graphene composite rubber. (Drawing includes non-English language text).
