摘要（英）：

The invention relates to a flame-retardant insulation polyvinylchloride cable sheath material and a preparation method thereof, and relates to the technical field of cable processing. The material is prepared from the raw materials of, by weight, 80-90 parts of PVC, 50-60 parts of butyl rubber, 30-40 parts of pentaerythritol, 5-15 parts of trioctyl trimellitate, 10-20 parts of chlorinated paraffin, 8-10 parts of calcium stearate, 5-15 parts of a flame retardant, 8-12 parts of a lubricant, 3-5 parts of an antioxidant, and 12-14 parts of calcium carbonate. The process flow is simple; raw material formulation is reasonable; and a reasonable raw material is provided for cable sheath production. The material has the advantages of high flame retardant property, high insulation strength, and better application effect. With the material, the quality of cable products is ensured.
