Abstract

The invention discloses a chlorinated-esterified polybutadiene rubber modified polyvinyl chloride cable material which is prepared from the following raw materials: polyvinyl chloride, chlorinated-esterified polybutadiene rubber, modified pyrophyllite, calcined argil, zinc oxide, stearic acid, epoxy resin, polysulfide rubber, triphenyl phosphate, a methyl methacrylate-butadiene-styrol copolymer, epoxy butyl oleate, a thermal stabilizer, polyhydric alcohols, aluminum hydroxide, diisooctyl phenyl phosphate, dilauryl thiodipropionate, a coupling agent, barium stearate and dicumyl peroxide. The chlorinated-esterified polybutadiene rubber modified polyvinyl chloride cable material disclosed by the invention is high in shock strength and good in thermal stability and has excellent flame-retardant, wear-resistant and corrosion-resistant properties.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a chlorinated butadiene rubber modified polyvinyl chloride cable material. Background technique [0002] Polyvinyl chloride has excellent comprehensive properties such as flame retardancy, wear resistance, insulation, acid and alkali resistance, low price, and a wide range of raw material sources. It has been widely used in various fields of the national economy such as industry, agriculture, and daily life. In recent years, the huge demand for polyvinyl chloride products in the construction market has made polyvinyl chloride products a very competitive product, and its output ranks second only to polyethylene. However, the disadvantages of low impact strength and poor thermal stability of polyvinyl chloride limit its development in fields with high performance requirements, and it needs to be modified. Contents of the invention [0003] The invention provides a chloro...
