▎ 摘　　要

NOVELTY - Composition comprises 1-65 pts. wt., preferably 5-50 pts. wt. polyvinyl chloride, 1-55 pts. wt., preferably 20-45 pts. wt. ultra-high molecular weight polyethylene, 1-20 pts. wt., preferably 10-15 pts. wt. stabilizer, 3-45 pts. wt., preferably 10-30 pts. wt. modifier, 2-10 pts. wt., preferably 3-5 pts. wt. lubricant, 0-15 pts. wt., preferably 3-9 pts. wt. composite antistatic agent. The stabilizer is chlorinated polyethylene or composite lead salt heat stabilizer. The modifier is Methyl Methacrylate Butadiene Styrene polymer (MBS), polyamide (PA), stearic acid, lead stearate, microbead filler or acrylonitrile butadiene styrene (ABS) resin. The lubricant is paraffin or molybdenum disulfide. The composite antistatic agent comprises polyvinyl chloride (PVC) antistatic agent, carbon black and graphene. USE - Composition for preparing carrier roller body, preferably ceramic carrier roller used in carrier roller bearing seat of a vehicle. ADVANTAGE - The composition has excellent flame-retardant, antistatic and wear-resistant ability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Method for preparing composition, which involves mixing polyvinyl chloride, ultrahigh molecular weight polyethylene, stabilizer, modifier and lubricant to obtain first mixture; and mixing the first mixture with a composite antistatic agent to obtain composition. Method for preparing carrier roller body using composition, which involves: (1) granulating the composition to obtain composition particles; and (2) extruding and molding the composition particles to obtain the carrier roller body.
