The composite masterbatch comprises graphene, sodium polyacrylate, cationic surfactant, filler, microcrystalline cellulose, solvent (A), silicone rubber and plant polyphenol. The filler comprises aluminum powder, titanium dioxide and pyrophyllite powder. USE - Graphene composite polypropylene fiber. ADVANTAGE - The graphene composite polypropylene fiber has excellent comprehensive performance. DETAILED DESCRIPTION - A graphene composite polypropylene fiber comprises 10-25 pts. wt. composite masterbatch, 70-90 pts. wt. polypropylene, 30-40 pts. wt. solvent and 2-5 pts. wt. surfactant. The solvent is ester or alcohol. Alcohol is methanol, ethanol or propanol. Ester is ethyl acetate, butyl acetate or isopropyl acetate. The composite masterbatch comprises 10-29 pts. wt. graphene, 10-30 pts. wt. sodium polyacrylate, 1-5 pts. wt. cationic surfactant, 15-30 pts. wt. filler, 1-2 pts. wt. microcrystalline cellulose, 10-30 pts. wt. solvent (A), 1-3 pts. wt. silicone rubber and 1-4 pts. wt. plant polyphenol. The filler comprises aluminum oxide, aluminum powder, titanium dioxide and pyrophyllite powder. The solvent (A) is ethanol or acetone. Graphene is graphene layer. An INDEPENDENT CLAIM is included for preparation of graphene composite polypropylene fiber, which involves weighing raw materials and then mixing, heating the mixture and then stirring, extruding the mixture and then rolling, and stretching.
