Abstract

The invention discloses a cable with good toughness and excellent thermal stability. The cable comprises a conductor and a protective jacket layer which covers the outer side of the conductor, wherein the protective jacket layer is prepared from the following raw materials in parts by weight: 20 to 40 parts of EVA (Ethylene Vinyl Acetate) resin, 5 to 15 parts of hydrogenated nitrile butadiene rubber, 12 to 15 parts of ABS (Acrylonitrile Butadiene Styrene) high-glue powder, 2 to 6 parts of microcrystalline cellulose, 5 to 15 parts of composite microsphere, 1 to 5 parts of nano hydroxyapatite powder, 5 to 12 parts of talcum powder, 2 to 6 parts of medical stone, 10 to 20 parts of oil shale, 12 to 15 parts of asbestos ash, 2 to 3 parts of ammonium polyphosphate, 1 to 2 parts of yttrium oxide, 1 to 3 parts of bis-2,4-dichlorobenzoyl peroxide, 1 to 2 parts of zinc dimethyldithioformate, 1 to 2 parts of butyl stearate, 1 to 3 parts of tetrabutylammonium bromide, 1 to 2 parts of zinc oxide, 2 to 3 parts of magnesium oxide, 24 to 28 parts of triethyl citrate, 8 to 10 parts of dimethyltin bis(isooctylmercaptoacetate), 25 to 30 parts of triethyl citrate, 1 to 2 parts of an anti-ageing agent AW and 0.8 to 1.2 parts of an anti-ageing agent A.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable with good toughness and excellent thermal stability. Background technique [0002] Cables are often used in some harsh environments, so the performance requirements of the cable sheath are high, and many modifications are needed to improve performance and increase the service life of the cable sheath material. The cable sheath that has appeared on the market at present The raw materials of sheathing materials include LDPE, LLDPE, HDPE, EVA, etc., but other modifiers need to be added for sheathing materials. Ethylene-vinyl acetate copolymer resin has good flexibility, impact resistance, environmental stress crack resistance, optics and low temperature resistance, and can be widely used in cable sheathing, but its toughness, thermal stability and aging resistance Still can't meet the demand. Contents of the invention [0003] Based on the technical problems existing in t...
