Abstract

The invention provides a wear-resistant flame-retardant cable sheath compound, which contains the following raw materials in parts by weight: 75-80 parts of PVC resin, 15-22 parts of vinyl chloride-acetate copolymer, 13-18 parts of polyvinylidene fluoride, 8-12 parts of neoprene, 13-15 parts of butadiene-acrylonitrile rubber, 5-8 parts of butadiene styrene rubber, 3-9 parts of butadiene rubber, 10-12 parts of fiberglass, 8-14 parts of carboxymethyl cellulose, 1-3 parts of carbon black, 1-3 parts of white carbon black, 1.5-2 parts of talcum powder, 0.5-1.8 parts of zinc oxide, 1.5-2 parts of magnesium oxide, 5-8 parts of nano calcium carbonate, 5-8 parts of Nano-Si powder, 5-7 parts of Nano-xuancheng stone, 6-12 parts of Insect repellent, 5-10 parts of sulphur, 5-10 parts of Tertiary stearic acid, 6-12 parts of pitch, 14-16 parts of composite flame retardant, 15-19 parts of filler, and 1-3 parts of plasticizer. By taking a mixture of PVC resin, butadiene styrene rubber, butadiene-acrylonitrile rubber, EPDM rubber, neoprene and butadiene rubber as a base material, the wear-resistant flame-retardant cable sheath compound is excellent in flame-retardant performance; by adding other rawmaterials including composite flame retardant and the anti-aging agent, the anti-aging performance and flame-retardant performance of cables can be obviously enhanced, and the service life of the cable can be greatly prolonged.

Description

technical field [0001] The invention relates to cable materials, in particular to a wear-resistant and flame-retardant cable sheath material. Background technique [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. A cable is usually a rope-like cable twisted by several or groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Highly insulating cable jacket. The cable has the characteristics of internal electrification and external insulation. [0003] After entering the modern society, due to the shortage of urban land, heavy traffic pressure, city appearance construction and other reasons, large cities generally adopt underground cable transmission. Compared with overhead cables, underground cables have the advantages of small footprint, reliable power transmission, and strong anti-interference ability. [0004] But ...
