Modified low-temperature-resistant fluorine rubber cable material

Abstract

The invention relates to a cable material, and in particular relates to a modified low-temperature-resistant fluorine rubber cable material. The cable material is prepared from the following raw materials in parts by weight: 55 to 60 parts of fluorine rubber 246, 6 to 8 parts of benzyl triphenyl phosphorus chloride, 18 to 24 parts of ethylene vinyl acetate copolymer, 18 to 23 parts of calcium carbonate, 3 to 4 parts of stearic acid, 5 to 9 parts of naphthenic oil, 3 to 4 parts of colza oil, 4 to 5 parts of dibutyl ester, 2 to 3 parts of calcium oxide, 3 to 4 parts of zinc oxide, 0.1 to 0.5 part of scorch retarder CTP (Cytidine Triphosphate), 2 to 3 parts of sulphur, 1 to 2 parts of accelerant DM, 3 to 5 parts of propanediol sebacate polyester, 6 to 8 parts of inositol hexaphosphate, 10 to 12 parts of iron oxide red, 34 to 38 parts of N339 carbon black, 14 to 18 parts of N550 carbon black, 1 to 2 parts of anti-aging agent RD and 4 to 5 parts of auxiliary agent. The modified cable material has the advantages of low-temperature resistance, aging resistance, good chemical stability and the like by improving the characteristics of the traditional fluorine rubber cable material. Meanwhile, the cost of the cable material is lowered. Thus, the modified cable material can meet the use requirements of a specific occasion. In addition, the modified cable material is harmless to environments and human bodies. The modified cable material provided by the invention has broad market prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to a low temperature-resistant modified fluorine 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, and short service life. It brings a lot of inconvenience and even threatens the safety of people's lives and properties. Therefore, it is ur...

[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. Performance and other indicators have strict requirements. 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, and short service life. It brings a lot of inconvenience 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.
