Abstract

The invention discloses a waterproof cable with a compact structure and a small gap. The cable comprises a conductor and a jacket layer covering the outer side of the conductor, wherein the jacket layer is prepared from the following raw materials in parts by weight: 26 to 32 parts of nitrile rubber, 20 to 35 parts of silicone rubber, 10 to 20 parts of chlorinated polyethylene, 1.5 to 2.5 parts of dicumyl peroxide, 1 to 2 aprts of N,N'-m-phenylenedimaleimide, 0.3 to 0.4 part of potassium ammonium dichromate, 0.4 to 0.8 part of poly-p-nitrosobenzene, 0.4 to 1.2 parts of dioctyl phthalate, 2 to 4 parts of bis(2-ethylhexyl) phthalate, 2 to 4 parts of chlorinated paraffin, 45 to 65 parts of white carbon black, 4 to 10 parts of diatomite, 8 to 12 parts of sepiolite, 10 to 18 parts of modified corn fibers, 1.5 to 2.5 parts of 2-ethylhexyl 9,10-epoxyoctadecanoate, 1.5 to 2.5 parts of epoxidized methyl linoleate, 1.5 to 2.5 parts of tributyl citrate, 8 to 16 parts of wheat protein, 1.5 to 3.5 parts of zinc stearate, 1 to 2 parts of antioxidant 264, and 2 to 3 parts of ultraviolet absorbent UV-531.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a waterproof cable with a tight structure and small gaps. 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 existing in the background technology, the present invention proposes a wat...
