Abstract

The invention discloses a salt-contamination-resistant cable material and a preparation method thereof. The salt-contamination-resistant cable material is prepared from the following raw materials in parts by weight: 52-62 parts of ethylene propylene diene monomers, 8-16 parts of butadiene rubber, 6-10 butadiene-acrylonitrile rubber, 3-5 parts of alkylated diphenylamines, 5-7 parts of methylacrylamide, 3-5 parts of butylated hydroxytoluene, 2-4 parts of sodium hexametaphosphate, 3-5 parts of mercaptoethanol, 4-6 parts of tricresyl phosphate, 2-4 parts of methyl salicylate, and tricresyl phosphate which is 4-6 times in parts by weight of the methyl salicylate. The cable material disclosed by the invention has excellent salt-contamination resistance, and is suitable for preparation of marine cables, and long in service life.

Description

technical field [0001] The invention relates to a cable material, in particular to a salt corrosion resistant cable material and a preparation method thereof. Background technique [0002] In marine power stations, cables are indispensable, but the performance of cables for land-use wind power does not take into account the special environment of marine wind power, especially does not have the ability to withstand long-term ocean salt, acid, alkali corrosion, oil corrosion, and seawater wet immersion resistance. When the sea wind power generation is reversed, it is easy to break down, shorten the service life, cause the cost of the project to increase or even be shelved. [0003] The development of salt-resistant cable materials can help improve the service life of marine cables. Contents of the invention [0004] The object of the present invention is to provide a cable material resistant to salt corrosion and a preparation method thereof. [0005] Above-mentioned purpo...
