Environmentally-friendly flexible polyvinyl chloride cable sheath composition

Abstract

The invention discloses an environmentally-friendly flexible polyvinyl chloride cable sheath composition. The environmentally-friendly flexible polyvinyl chloride cable sheath composition is prepared from, by weight, 20-30 parts of bisphenol, 12-30 parts of stearic acid, 22-30 parts of ABS resin, 28-36 parts of polyvinyl chloride resin, 9-20 parts of ABS high-glue powder, 8.9-12.6 parts of an antioxidant 1035, 25-36 parts of maleic anhydride grafted ethylene, 5-9 parts of a vinyl acetate copolymer, 6-16 parts of mullite powder, 13-22 parts of asbestos powder, 31-39 parts of calcium carbonate, 10-15 parts of perlite, 9.3-15.2 parts of poly acid ammonium, 35-38 parts of pentaerythritol, 25-39 parts of antimony trioxide slightly crosslinked resin, 19-39 parts of a flame retardant, 10-20 parts of a flame retardant synergist, 20-26 parts of chlorinated rubber, 8.2-18.6 parts of an ultraviolet light absorber, 15-22 parts of a stabilizer, 30-35 parts of a lubricant, 42-49 parts of a calcium carbonate material and 55-59 parts of a polypropylene material. The environmentally-friendly flexible polyvinyl chloride cable sheath composition is simple in technological process and reasonable in raw material proportion, has good thermal insulation and fire proofing property, ensures the normal use of a cable, prolongs the service life of the cable, is good in use effect and guarantees the quality of a cable product.

Description

technical field [0001] The invention relates to an environment-friendly flexible polyvinyl chloride cable jacket formula. Background technique [0002] With the development of my country's economy and the rapid development of the communication industry, more and more high-power equipment is used, which puts forward higher requirements for the performance of cables. The withstand power of the cable is linearly related to the difference between the maximum temperature of the inner conductor and the ambient temperature, and the maximum working temperature of the inner conductor is limited by the cable insulation material. The long-term working temperature of the cable insulation material is the maximum allowable working temperature of the inner conductor, but at present Most of the cable materials on the market do not have excellent high temperature resistance and cannot meet the needs of current high-power equipment. Therefore, the present inventor has created a new type of c...
