▎ 摘  要

NOVELTY - Graphene modified super weathering powder coating comprises 40-60 pts. wt. polyester resin, 1-5 pts. wt. temperature gradient interaction chromatography curing agent, 18-22 pts. wt. barium sulfate, 1-3 pts. wt. mica powder, polytetrafluoroethylene. 1-2 pts. wt. ethylene wax, 1-3 pts. wt. leveling agent, 1-2 pts. wt. humectant, 10-18 pts. wt. rutile titanium dioxide, 1-5 pts. wt. weather resistant pigment, and 3-5 pts. wt. graphene-modified aging agent. USE - Graphene modified super weathering powder coating. ADVANTAGE - The graphene modified super weathering powder coating has excellent weather resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing a graphene-modified super weather-resistant powder coating, which involves: (A) adding polyester resin, TGIC curing agent, barium sulfate, mica powder, polytetrafluoroethylene wax, leveling agent, wetting agent, rutile titanium dioxide, weathering pigment, graphene modified aging agent are added according to the ratio, stirring and mixing in a mixer; and (B) extruding, tableting, cooling, crushing and sieving through a twin-screw extruder to form a graphene-modified super weather-resistant powder coating.
