Abstract

The invention discloses a flame-retardant insulating cable material and a preparation method thereof. The flame-retardant insulating cable material is prepared from the following raw materials in parts by weight: 25-40 parts of nitrile rubber, 25-35 parts of polybutadiene rubber, 15-25 parts of a vinyl chloride-acrylate copolymer, 5-10 parts of polyimide fibers, 15-25 parts of a flame retardant, 8-15 parts of a filling agent, 3-8 parts of an anti-aging agent, 10-23 parts of a softener, 1-3 parts of an accelerant and 2-6 parts of a crosslinking agent. The flame-retardant insulating cable material prepared by the method is good in strength and toughness, excellent in high temperature resistance and low temperature resistance, and good in flame retardant property.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant insulating cable material and a preparation method thereof. Background technique [0002] The surface of power cables needs to be covered with cable materials. Cable materials are the technical core and key to form high-voltage and ultra-high-voltage power transmission and transformation equipment and networks. The performance and stability of the cables are directly related to the voltage level and safety of the entire transmission network. The cable material has low strength and poor high and low temperature resistance, which affects the service life of the power cable. [0003] The Chinese patent application with the publication number CN108164878A discloses a kind of anti-corrosion, wear-resistant and flame-retardant cable material, including 20-50 parts of polyvinyl chloride resin, 10-20 parts of EVA resin, 15-30 parts of neoprene rubb...
