The invention discloses a modified chlorinated polyvinyl chloride insulating cable sleeve material which is prepared from the following raw materials: chlorinated polyvinyl chloride, chlorinated polyethylene, ABS particles, pyrophyllite powder, fluorocarbon resin, polyisobutylene, polyvinylidene fluoride, EBS, a regulator, a stabilizer, ammonium polyphosphate, potassium aluminum silicate, melamine bromate, polysiloxane resin, talcum powder, ferrophosphorus fluoride and chlorinated polypropylene. The modified chlorinated polyvinyl chloride insulating cable sleeve disclosed by the invention has the advantages of good fireproof performance, low flame expansibility, low smoke generation, automatic extinguishment, no fire drop generation and the like, overcomes the defects of easy breakage and poor impact of the traditional cable sleeve, has high strength, good flexibility, high temperature resistance, corrosion resistance, good flame resistance and good insulating performance, is greatly superior to the traditional asbestos cable duct and common polyvinyl chloride pipe materials in performance, and is an ideal substitute for the traditional power cable sheath pipe. |
