The cable comprises a conductor and a sheath layer which coats the outer side of the conductor, wherein the sheath layer comprises the following raw materials in parts by weight: 25-45 parts of ethylene-propylene-diene-terpolymer rubber, 16-22 parts of EVA (ethylene-vinyl acetate copolymer) resin, 10-20 parts of natural rubber, 3-7 parts of nanometer hydroxyapatite micromist, 8-16 parts of kieselguhr, 15-25 parts of saw dust powder, 4-6 parts of ammonium polyphosphate, 16-20 parts of turf powder, 4-8 parts of sea-foam stone powder, 2-4 parts of yttrium oxide, 10-20 parts of composite microsphere, 4-8 parts of microcrystalline fiber, 4-6 parts of magnesium oxide, 2-4 parts of zinc oxide, 2-6 parts of tetrabutylammonium bromide, 2-4 parts of pentaerythritol ester, 12-16 parts of dimethyl mercaptopropionic acid isooctyl ester tin, 30-35 parts of tricresyl phosphate, 2-4 parts of zinc-ethylphenyl dithiocarbamate, 2-5 parts of dicumyl peroxide, 1.5-2.5 parts of antiager H and 1-1.8 parts of antiager D.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aging-resistant cable with excellent toughness. 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 in the background techn...
