▎ 摘 要
NOVELTY - The radiator has a heat dissipation base and a heat dissipation scale that are provided. The outer surface of heat dissipation scale is coated with a graphene coating. The graphene coating comprises a graphene oxide, a solvent, a dispersant, an adhesive, a thickener, a composite conductive agent, a carbon fiber filler, a hydrophobic filler and a low surface energy organic substance. The graphene coating has a thickness of 5-20 mu m. The solvent in the composition of the graphene coating is water, and the dispersing agent is tetrahydrofuran. The composite conductive agent in the composition of graphene coating is a mixture of acetylene black, ketjen black and carbon nanotubes. The mass ratio of acetylene black, ketjen black and carbon nanotubes is 1:1:2. USE - Graphene heat conductive coating modified radiator. ADVANTAGE - The radiator has excellent thermal conductivity, and by adding carbon fiber filler and hydrophobic filler to the graphene heat conductive coating. The radiator enhances the thermal conductivity, wear resistance, hydrophobicity and corrosion resistance of graphene thermal conductive coatings.
