Abstract

The invention discloses a cable with good toughness and excellent thermal stability. The cable comprises a conductor and a protective sheath layer, wherein the protective sheath layer coats the conductor; the protective sheath layer is prepared from the following raw materials in parts by weight: 15 to 25 parts of ethylene propylene diene monomer, 60 to 90 parts of chloroprene rubber, 20 to 30 parts of nitrile rubber, 15 to 25 parts of light-weight calcium carbonate, 14 to 22 parts of glass fiber, 20 to 40 parts of nerchinskite, 25 to 35 parts of modified clay, 1 to 2 parts of epoxidized soybean oil, 2 to 4 parts of coal tar, 0.4 to 0.8 part of polyethylene wax, 0.4 to 1 part of stearic acid, 0.4 to 1 part of bis(2,4-dichlorobenzoyl peroxide), 1.5 to 2.5 parts of succinic acid peroxide, 0.3 to 0.7 part of 2-ethyl-4-methylimidazole, 0.8 to 1.4 parts of bispheno1-A diglycidyl ether and 2 to 4 parts of anti-aging agent. The cable has the advantages that the hydrophobic and tear-resistant properties are good, the toughness is excellent, and the heat stability is stronger.

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] During the use of the cable, if the outer sheath layer of the cable is damaged or melted at high temperature and the conductor in the center of the cable leaks, it will cause a safety hazard. The safety of the cable sheath layer is extremely important to prevent other people from causing irreparable harm. At present, with the development of social economy, my country's demand for cable market continues to expand and investment in cable research continues to deepen, and the quality requirements for cables are constantly improving. It will not be damaged by strong impact, and it also needs to have strong thermal stability. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a cable with good toughness and excellent ...
