NOVELTY - Air duct comprises 20-30 pts. wt. polypropylene homopolymer, 1.5-3.5 pts. wt. lubricant, 1-2 pts. wt. polyacrylate, 5-10 pts. wt. antistatic filler, and 1-4.5 pts. wt. liquid paraffin, where the preparation of antistatic filler comprises (a) bonding graphene powder on carbon fiber surface with epoxy resin binder to obtain first material, and (b) modifying surface of first material by quaternary ammonium salt type cationic surfactant with a long alkyl chain to obtain antistatic filler. USE - The air duct is useful for conveying and distributing air. ADVANTAGE - The duct: has good antistatic performance, high temperature resistance, improved electrical conductivity, and improved anti-ultraviolet performance.
