Abstract

The invention discloses a high-strength and wear-resistant cable. The high-strength and wear-resistant cable comprises a conductor, an insulating layer wrapping the conductor, a filling layer wrapping the insulating layer, a shielding layer wrapping the filling layer, an armoring layer wrapping the shielding layer and an outer sheath wrapping the armoring layer. The outer sheath is composed of the following raw materials in parts by weight: 60 to 65 parts of natural rubber; 20 to 23 parts of chloroprene rubber; 17 to 20 parts of butyl rubber; 12 to 15 parts of polytetrafluoroethylene modified aramid pulp material; 1.5 to 1.8 parts of dicumyl peroxide DCP; 2.2 to 2.5 parts of sulfur; 1.6 to 1.9 parts of sodium cinnamate; 1.4 to 1.7 parts of triethanolamine; 18 to 22 parts of barite powder; 7 to 10 parts of magnesium oxide; 5 to 8 parts of sepiolite powder; 6 to 9 parts of hard clay; 1.6 to 2.2 parts of titanate coupling agent KR-TTS; 4 to 8 parts of magnesium hydroxide; 8 to 10 parts of trioctyl trimellitate; 1.5 to 1.8 parts of antioxidant 800-A; and 1.2 to 1.5 parts of antioxidant 4020.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength wear-resistant and fire-resistant cable. Background technique [0002] The safe use of cables is related to the safety of people's production and life. At present, most of the cables on the market, especially the outer sheaths of cables, have mediocre performance, poor strength and wear resistance, which leads to cracks when the cables are subjected to external forces. Therefore, it is necessary to develop a high-strength, wear-resistant cable. At the same time, with the gradual increase of the cable load, it is also necessary to enhance the fire resistance of the cable. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a high-strength wear-resistant and fire-resistant cable with high toughness, excellent shock absorption effect, and excellent wear-resistant and fire-resistant performa...
