▎ 摘  要

NOVELTY - Heat dissipation coating comprises 40-55 parts mass resin, 8-11 parts mass curing agent, 25-28 parts mass thinner, 2-5 parts mass graphene, 2-5 parts mass boron nitride, 2-5 parts mass silicon carbide and 4-10 parts mass alumina. USE - The coating is useful for a lamp radiator (claimed). ADVANTAGE - The coating utilizes excellent thermal and mechanical properties of graphene and inorganic fillers, has improved stacking between graphene, improves processing dispersibility of graphene, improves the selling phase of graphene coatings, and is prepared by simple and cost-effective method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the coating, involving (i) fully stirring, mixing resin, thinner and curing agent at normal temperature and normal pressure so as to ensure the uniform mixing of the components and obtaining a mixture (A), (ii) mixing graphene, boron nitride, silicon carbide and alumina at normal temperature and normal pressure to obtain a mixture (B), and (iii) adding the mixture (B) to the mixture (A), and carrying out high-speed stirring and dispersing for 2 hours to obtain the product.
