The high-strength anti-oxidation flame-retardant cable material has excellent flame retardance, heat resistance and ageing resistance and good sealing property.

Description

technical field

[0001] The invention relates to the technical field of cable materials, in particular to a high-strength oxidation-resistant and flame-retardant cable material. Background technique

[0002] Chlorinated polyethylene resin is a new type of synthetic material with a series of excellent properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive properties. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, and flame-retardant conveyor belts. , Waterproof membrane, film and various profiled materials and other products. CPE can also be blended with polypropylene, high and low pressure polyethylene, ABS, etc. to improve the flame retardancy, aging resistance and printing performance of these plastics. CPE can be regarded as a random copolymer of ethylene, polyethylene and 1,2-dichloroethylene. Its molecular chain is s...
