The invention provides a super-weatherability powder coating for electrostatic spraying. The coating is prepared from, by mass, 34.29% of polyester resin, 3.02% of epoxy resin, 2.01% of carbon black, 1.71% of pigment, 29.35% of titanium dioxide, 24.52% of barium sulfate, 1.20% of flatting agent, 0.80% of brightener, 0.10% of graphene, 1.2% of nanometer titanium nitride, 0.8% of rare earth mixture, 0.5% of phosphotungstic acid and 0.5% of quartz. The coating is simple in composition and reasonable in matching; graphene nanoplatelets are added to improve the electrostatic spraying performance; the coating has excellent chemical resistance and weather resistance as well as high decoration performance, can be applied to coating of factory equipment and facilities, automobile bodies, household appliances, aluminum alloy curtain walls and television launch towers and other durable and protective decoration industries, and can be widely applied to the fields of bridges, doors, windows, enclosures, household coloring materials and other building materials.
