▎ 摘　　要

NOVELTY - Heat dissipation coating includes a bottom layer, an intermediate layer and a surface layer in sequence from the inside to the outside. The bottom layer of the heat dissipation coating includes 45-55 pts. wt. epoxy resin, 90-110 pts. wt. silicon powder, 2-20 pts. wt. zinc powder and 45-55 pts. wt. phthalic anhydride curing agent. The intermediate layer includes 0.009-0.11 pts. wt. graphene and its derivatives, 0.1-1 pts. wt. oxides, 45-55 pts. wt. acrylic resin, and 45-55 pts. wt. isocyanate curing agent. The surface layer includes 0.009-0.11 pts. wt. graphene and its derivatives, 45-55 pts. wt. fluorocarbon resin, and 45-55 pts. wt. isocyanate curing agent. USE - Heat dissipation coating for energy transformer. ADVANTAGE - The heat dissipation coating improves the thermal conductivity and corrosion resistance, and prolongs the reliability and service life of the energy transformer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of energy transformer heat-dissipating coating, involves performing surface pretreatment of transformer components, spray-coating (A) on the surface of the transformer component and curing to prepare a coating bottom layer, then spray-coating (B) on the bottom layer and curing to prepare a coating intermediate layer, and then spray-coating (C) on the intermediate layer and curing to prepare a coating surface layer.
