Polyvinyl chloride composite material for coal mine carrier roller and preparation method thereof

The invention relates to the technical field of novel functional polymer materials, in particular to a polyvinyl chloride composite material for a coal mine carrier roller and a preparation method of the polyvinyl chloride composite material. The polyvinyl chloride composite material for the coal mine carrier roller comprises the following components in parts by weight: 100 parts of PVC resin, 1-3 parts of a processing aid, 0.6-6 parts of a heat stabilizer, 6-14 parts of a flexibilizer, 0.2-2 parts of a lubricant, 2-12 parts of a composite wear-resistant modifier and 0.1-8 parts of an antistatic filler, the PVC resin is formed by mixing PVC resin with a medium polymerization degree and PVC resin with a high polymerization degree; the polymerization degree of the PVC resin with the medium polymerization degree is 900-1200, and the polymerization degree of the PVC resin with the high polymerization degree is 2200-2600. The material has the advantages of being good in wear resistance, high in impact resistance,
