High-heat-resistant oil-resistant ethylene-acrylate rubber cable material

Abstract

The invention relates to a cable material, particularly a high-heat-resistant oil-resistant ethylene-acrylate rubber cable material which comprises the following raw materials in parts by weight: 40-45 parts of ethylene-acrylate rubber (AEM), 20-24 parts of N339 carbon black, 12-15 parts of fluororubber, 20-24 parts of polystyrene, 1.5-2.5 parts of triallyl isocyanurate, 1.1-1.3 parts of accelerator CZ, 0.19-0.21 part of accelerator TT, 5-6 parts of zinc stearate, 18-22 parts of N220 carbon black, 20-22 parts of silica white, 2-4 parts of dibutyl maleate, 1-2 parts of imarcaptoacetate dioctyltin, 1-2 parts of dibasic lead phosphite, 1-2 parts of silane coupling agent KH550, 2-3 parts of crosslinking agent TAC, 5-8 parts of diglycol benzoate and 4-5 parts of assistant. The cable material combines the advantages of the AEM, fluororubber, polystyrene and other raw materials, and enhances the properties of the traditional ethylene-acrylate rubber cable material; and thus, the ethylene-acrylate rubber cable material has excellent high temperature resistance and oil resistance, can adapt to specific operating ambient conditions, is especially suitable for a high-temperature high-oil environment, and has wide market application prospects.

Description

technical field [0001] The invention relates to a cable material, in particular to an ethylene-acrylate rubber cable material with high heat resistance and oil resistance 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 s...

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.
