▎ 摘　　要

NOVELTY - Preparing weather resistant powder coating involves mixing polyester resin, curing agent, leveling agent, pigment, filler, degassing agent, ultraviolet absorber, and modified graphene powder in a mass ratio of (150-160):(10-20):(2-3):(50-60):(75-85):(0.5-0.6):(0.1-0.12):(33-36), extruding in an extruder, crushing and sieving to obtain weather resistant powder coating. USE - Method for preparing weather resistant powder coating (claimed). ADVANTAGE - The method enables to prepare weather resistant powder coating, which shows accelerated photoaging test in 480 hours, where retention rate reaches more than 97%.
