Abstract

The invention discloses a modified chlorinated polyvinyl chloride insulated cable sleeve material. The material is prepared from the following raw materials of: chlorinated polyvinyl chloride, chlorinated polyethylene, ABS particles, pyrophyllite powder, fluorocarbon resin, polyisobutene, polyvinylidene fluoride, EBS, a regulator, a stabilizer, ammonium polyphosphate, potassium aluminum silicate,melamine bromate, polysiloxane resin, talcum powder, fluorine ferrophosphorus and chlorinated polypropylene. The modified chlorinated polyvinyl chloride insulated 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 a traditional cable sleeve, and has the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardance, good insulating property and the like. Performance of the modified chlorinated polyvinyl chloride insulated cable sleeve is greatly better than that of a traditional asbestos cable duct bank and a common polyvinyl chloride pipe, and is an ideal substitute of a traditional power cable sheath pipe.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a modified chlorinated polyvinyl chloride insulating cable sleeve material. Background technique [0002] With the rapid development of power cable buried laying projects, higher requirements are put forward for cable bushings. Cable bushings are suitable for telecommunications, power engineering, transportation, urban construction and other fields. There are generally two types of bushings: steel protective tubes and plastic tubes. Plastic pipes are generally made of polyvinyl chloride plastic or U-PVC, there are ordinary and flame-retardant types, the price is cheaper than metal pipes, the construction is convenient, and it will not rust. Most of the wire threading sheath tubes are made of plastic tubes. [0003] In order to protect the cables, protective tubes should be installed on the parts that are vulnerable to external force damage when the cables ...
