Low temperature-resistant insulated fluororubber cable material

Abstract

The invention relates to a cable material and specifically relates to a low temperature-resistant insulated fluororubber cable material. The cable material comprises the following materials in parts by weight: 20-23 parts of butadiene rubber, 12-15 parts of isoprene rubber, 10-12 parts of nylon PA (Polyamide), 20-24 parts of fluororubber, 20-23 parts of white carbon black, 24-28 parts of N330 carbon black, 15-20 parts of nano argil, 4-7 parts of paraffin oil, 2.2-3 parts of stearic acid, 1-2 parts of sulphur, 1-2 parts of dicumyl peroxide, 3-4 parts of epoxy octyl stearate, 3-4 parts of epoxy triglyceride fatty acid, 8-12 parts of N220 carbon black, 2-3 parts of zinc oxide, 1-2 parts of a silane coupling agent KH550, 1-2 parts of an accelerator M and 4-5 parts of auxiliaries. The cable material disclosed by the invention integrates advantages of butadiene rubber, isoprene rubber, fluororubber as well as nylon and the like, so that performance of the conventional fluororubber cable material is improved; the low temperature-resistant insulated fluororubber cable material disclosed by the invention has the advantages of being low temperature resistant, good in tensile property, good in flexibility, good in insulativity and the like, can satisfy using requirements of a specific occasion, and is harmless to environment and human body, and wide in application prospect.

Description

Technical field [0001] The invention relates to a cable material, in particular to a low-temperature resistant insulating fluorine rubber cable material and a preparation method thereof. Background technique [0002] With the development of economy, the demand for cables is broad, which promotes the progress of cable material production technology. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, use temperature, 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 and easy deformation, poor mechanical properties, and short service life. It brings a lot of inconvenience to actual use, and even threatens people's life and property safety. Therefore, it is...

Problems solved by technology

[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, 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.
