A kind of oil-resistant and chemical-corrosion-resistant modified tetrapropylene fluorine rubber cable material

Abstract

The invention relates to a cable material, and particularly relates to an oil-proof modified terafluoroethylene-propylene rubber cable material with chemical resistance. The cable material comprises the following raw materials in parts by weight: 25-30 parts of terafluoroethylene-propylene rubber, 23-25 parts of (1502-type) butadiene styrene rubber, 20-23 parts of isotactic polystyrene, 10-12 parts of metallocene linear low-density polyethylene, 1-2 parts of sulphur, 12-15 parts of ethylene / methacrylic acid (EMA), 4-6 parts of zinc oxide, 4-6 parts of chlorinated paraffin, 3-5 parts of zinc stearate, 6-8 parts of coumarone, 20-24 parts of nitrile rubber (N41), 24-28 parts of precipitated silica, 23-26 parts of N330 carbon black, 3-4 parts of diphenyl silanediol, 2-3 parts of isopropyl distearin acyloxy aluminic acid ester, 1-2 parts of antioxidant 168, 4-6 parts of epoxy flaxseed oil, 1-2 parts of monobutyltin oxide, and 4-5 parts of assistant. By adopting the cable material, the advantages of the raw materials such as the terafluoroethylene-propylene rubber, the butadiene styrene rubber, the nitrile rubber, the isotactic polystyrene, the metallocene linear low-density polyethylene, and the like are combined; the performance of the traditional terafluoroethylene-propylene rubber cable material is improved, so that the cable material has excellent mechanical property, oil resistance and chemical resistance, simultaneously also has good ageing resistance and long service life, can adapt to a specific use environment condition, and has a wide market application prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to an oil-resistant and chemical-corrosion-resistant modified tetrapropylene fluoro rubber cable material and a preparation method thereof. Background technique [0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, service temperature, and flame retardancy. There are strict requirements on performance and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have problems such as poor flame retardancy, high temperature deformation, poor mechanical properties, and short service life. It brings a lot of inconvenience to the actual use, a...

[0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, service temperature, and flame retardancy. There are strict requirements on performance and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have problems such as poor flame retardancy, high temperature deformation, poor mechanical properties, and short service life. It brings a lot of inconvenience to the actual use, and even threatens the safety of people's lives and property. Therefore, it is urgent to change the original cable material formula and improve the material performance to meet the diverse needs of the cable market.
