▎ 摘　　要

NOVELTY - Polyphenylene sulfide powder coating comprises 70-90 wt.% polyphenylene sulfide powder, 5-10 wt.% fluororesin powder, 1-8 wt.% high-dispersion graphene micro-sheet, and 4-26 wt.% inorganic filler. USE - The polyphenylene sulfide powder coating used in anti-corrosion coating applications. ADVANTAGE - The powder coating has high-efficiency barrier, toughening and wear-resisting functions, ensures smooth surface coating, does not have pinholes and shrinkage holes, and ensures improved mechanical and corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the polyphenylene sulfide powder coating, involving uniformly mixing the above-mentioned raw materials by high-speed mixer, granulating by twin-screw extruder, and further ball-milling to powder with size of 20 mum in liquid nitrogen medium.
