Cable with fluorine-modified polyacrylate sheath layer

Abstract

The invention discloses a cable with a fluorine-modified polyacrylate sheath layer. The cable comprises a cable core and a sheath layer which coats the cable core. Raw materials of the sheath layer comprise, by weight, 32-35 parts of nitrile rubber 2707, 24-27 parts of fluorine-modified polyacrylate, 23-26 parts of ethylene propylene diene monomer, 13-16 parts of para-aramid fibers, 11-14 parts of furnace black, 17-20 parts of mica, 8-11 parts of sepiolite, 3-5 parts of a mono-alkoxy titanate coupling agent, 2.3-3.5 parts of sulphur, 1.5-1.8 parts of an accelerant TT, 2.2-2.5 parts of an accelerant DM, 1.1-1.4 parts of an anti-aging agent SP, 2.3-2.6 parts of an anti-aging agent RD, 0.7-1.1 parts of stearic acid, 7-11 parts of phenyl petroleum sulfonate and 1-3 parts of castor oil. The cable has good waterproofness and oil-proof performance, and has excellent weather fastness and corrosion resistance. The preparation process is simple and easy to operate, and reaction conditions are mild. The cable is convenient for industrial production.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable with a fluorine-modified polyacrylate sheath layer. Background technique [0002] Cables are often exposed to the water environment in nature when they are in use. Traditional cables often do not have protective measures to cause moisture intrusion, damage the molecular structure of the outer surface of the cable, and cause the cable to disintegrate in severe cases, which seriously affects the safe service life of the cable. Especially some cables laid on the bottom of rivers, lakes and seas have to face this problem. At the same time, natural water often contains a large amount of salt, microorganisms and some pollutants, which can also cause serious corrosion to the cables laid therein. [0003] Studies have found that adding some materials with extremely low surface energy to the cable material can greatly reduce the surface energy of the cable and improve the waterpro...

[0002] Cables are often exposed to the water environment in nature during use. Traditional cables often do not have protective measures to cause moisture intrusion, damage the molecular structure of the outer surface of the cable, and cause the cable to disintegrate in severe cases, which seriously affects the safe service life of the cable. Especially some cables laid on the bottom of rivers, lakes and seas have to face this problem

At the same time, natural water often contains a large amount of salt, microorganisms and some pollutants, which can also cause serious corrosion to the cables laid therein.

[0003] Studies have found that adding some materials with extremely low surface energy to the cable material can greatly reduce the surface energy of the cable and improve the waterproof and oil-proof performance. However, how to further improve the weather resistance and corrosion resistance of these materials to strengthen the cable performance has not been studied
