Abstract

The invention discloses a cable with excellent mechanical properties. The cable comprises a conductor and a sheath layer covering the outer side of the conductor, wherein the sheath layer is prepared from the following raw materials in parts by weight: 15-28 parts of an ethylene-vinyl acetate copolymer, 22-28 parts of nitrile rubber, 5-15 parts of neoprene, 0.2-0.9 part of dioctyl adipate, 1-2 parts of dicyclohexyl phthalate, 1-2 parts of chlorinated paraffin, 0.5-1.2 parts of N,N'-m-phenylene bismaleimide, 1-2 parts of sulphur, 0.15-0.25 part of phenol-formaldehyde resin, 0.1-0.6 part of poly-p-nitrosobenzene, 5-10 parts of modified mulberry leaf powder, 40-60 parts of bentonite, 5-10 parts of active kaolin, 2-6 parts of kieselguhr, 5-12 parts of peanut protein, 1-2 parts of paraffin oil, 1-2 parts of epoxidized soybean oil, 1-2 parts of disproportionated rosin, 0.5-1.5 parts of an antioxidant 264, 0.5-1.5 parts of an anti-aging agent RD and 1-3 parts of zinc stearate.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable with excellent mechanical properties. Background technique [0002] For mobile cables used in water-immersed or wetland environments, traditional cables with ordinary rubber properties are often used in my country at present. According to statistics, in the quality accidents of the common cable used in the water environment, the waterproofing is not up to the standard. Dendritic discharge channels, which become water dendrites if moisture enters these channels. Water branches grow and will cause insulation breakdown and electrical failure. How to prepare a cable with good waterproof performance, compact structure, small pores and excellent mechanical properties has become a technical problem to be solved at present. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a cable with excellent mec...
