High temperature resistant and flame retardant nitrile rubber cable material

Abstract

The invention relates to a cable material, and specifically relates to a high temperature resistant and flame retardant nitrile rubber cable material. The cable material comprises the following raw materials in parts by weight: 45-50 parts of nitrile rubber (3445), 14-17 parts of ethylene propylene terpolymer, 4-5 parts of polytetrafluoroethylene, 23-26 parts of low density polyethylene, 1-2 parts of sulphur, 4-6 parts of zinc stearate, 24-28 parts of N339 carbon black, 4-5 parts of soybean oil, 12-15 parts of sepiolite powder, 4-5 parts of antimonous oxide, 18-22 parts of vermiculite powder, 3-5 parts of zinc oxide by an indirect method, 3-5 parts of zinc stearate, 2-4 parts of potassium citrate, 1-2 parts of decabromodiphenylethane, 1-2 parts of acrylonitrile and 4-5 parts of an assistant. The cable material combines the advantages of nitrile rubber, ethylene propylene terpolymer, low density polyethylene and other assistant raw materials, and enhances performance of conventional nitrile rubber cable materials, so that the high temperature resistant and flame retardant nitrile rubber cable material has the advantages of high temperature resistance, flame retardance, aging resistance, storage resistance and the like, can satisfy the using demand of special occasions, and is harmless to the environment and human body and broad in application prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to a high-temperature-resistant and flame-retardant nitrile 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. 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 ...

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.
