NOVELTY - Aqueous graphene composite heat dissipation coating comprises component A and component B. The component A comprises reducing oxidation graphene slurry, aqueous epoxy resin, heat-conducting filler, auxiliary agent and water. The reducing oxidized graphite slurry is prepared by heat-reducing and oxidizing graphite. The Mohs hardness of the heat conducting filler is not less than 7. The B component comprises epoxy curing agent and the water. USE - Aqueous graphene composite radiating coating. ADVANTAGE - The aqueous graphene composite radiating coating has good radiating effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method-based graphene composite radiating coating, which involves mixing reducing oxidation graphene slurry, auxiliary agent and water, adding heat-conducting filler, continuously mixing, adding aqueous epoxy resin, continuously mixing to prepare component A; mixing epoxy curing agent and water to prepare component B; and mixing the A component and the B component in ratio of 8-15:1 and curing.
