Modified heat-proof anti-oxidation nitrile rubber cable material

Abstract

The invention relates to a cable material, and in particular relates to a modified heat-proof anti-oxidation nitrile rubber cable material which is prepared from the following raw materials in parts by weight: 30 to 34 parts of nitrile rubber (N41), 10 to 12 parts of granulated cork, 20 to 24 parts of epichloro-hydrin rubber, 10 to 12 parts of SG-3 polyvinyl chloride, 10 to 12 parts of low-density polyethylene, 24 to 27 parts of N550 carbon black, 30 to 34 parts of N220 carbon black, 7 to 9 parts of adipic acid diester, 4 to 5 parts of N-cyclohexylthiophthalimide, 2 to 3 parts of titanate coupling agent TMC-TTS, 2 to 4 parts of stearic acid, 1 to 2 parts of accelerant Na-22, 12 to 14 parts of nano silicon dioxide, 2 to 3 parts of epoxy flaxseed oil, 1 to 2 parts of sulphur, 3 to 4 parts of zinc oxide, 3 to 4 parts of magnesium oxide and 4 to 5 parts of auxiliary agent. The performance of the traditional nitrile rubber cable material is improved by combining the advantages of the nitrile rubber, the epichloro-hydrin rubber, the SG-3 polyvinyl chloride, the low-density polyethylene and the other raw materials. Thus, the modified heat-proof anti-oxidation nitrile rubber cable material is superior in processability and usability, and has the characteristics of heat resistance, oxidation resistance, aging resistance and the like. Therefore, the modified heat-proof anti-oxidation nitrile rubber cable material can adapt to specific application environment conditions, thereby having broad market application prospect.

Description

Technical field [0001] The invention relates to a cable material, in particular to a heat-resistant and oxidation-resistant modified nitrile 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. Theref...

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.
