NOVELTY - High thermal conductivity aluminum-based graphene composite material comprises 0.01-5 pts. wt. graphene, 0-4 pts. wt. melting point alloy, and 91-99.99 pts. wt. aluminum powder. USE - High thermal conductivity aluminum-based graphene composite material. ADVANTAGE - The high thermal conductivity aluminum-based graphene composite material significantly improves the thermal conductivity of the aluminum-based composite material, and has excellent mechanical properties, environmental protection and energy saving, and industrial mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high thermal conductivity aluminum-based graphene composite material, which involves: (A) dding graphene to the solvent and mixing in the dispersion device to obtain a uniform and stable graphene dispersion; (B) mixing the graphene dispersion liquid, aluminum powder and low melting point alloy powder uniformly into a slurry in proportion, and drying, and obtaining aluminum/graphene composite powder with uniformly dispersed graphene is obtained; (C) putting composite powder into a cemented carbide mold and pressing into a rod-shaped blank, and sintering under a protective atmosphere to obtain a sintered dense rod; and (D) performing hot extrusion molding of the sintered dense bar material to obtain an aluminum/graphene composite material.
