High-temperature steam-resistant and ageing resistant modified fluororubber cable material

Abstract

The invention relates to a cable material, and specifically relates to a high-temperature steam-resistant and ageing resistant modified fluororubber cable material. The cable material comprises the following raw materials in parts by weight: 30-35 parts of fluororubber, 15-18 parts of low density polyethylene, 3-4 parts of zinc oxide, 3-4 parts of 2, 5-dimethyl-2, 5-bi(tert-butyl peroxide) hexane, 2-3 parts of triallyl isocyanurate, 18-20 parts of SG-3 polyvinyl chloride, 10-13 parts of natural rubber, 12-15 parts of calcium carbonate powder, 3-4 parts of magnesium oxide, 1-2 parts of ferrocene, 2-3 parts of isocyanate, 5-8 parts of epoxidized soybean oil, 2-3 parts of isobutyl acrylate, 1-2 parts of sulphur, 30-34 parts of N339 carbon black, 24-28 parts of nano diatomite powder, 7-9 parts of linseed alkyd resin, 1-2 parts of an anti-aging agent NBC (Nickelous N,N-dibutyldithiocarbamate) and 4-5 parts of an assistant. The cable material combines the advantages of fluororubber, natural rubber, low density polyethylene, SG-3 polyvinyl chloride and the like, and enhances the performance of a conventional fluororubber cable material, so that the high-temperature steam-resistant and ageing resistant modified fluororubber cable material has good strength and toughness and excellent high-temperature steam corrosion resistance and ageing-resisting function, can be applicable to special using environmental conditions and has a broad market application prospect.

Description

technical field [0001] The invention relates to a cable material, in particular to a high-temperature steam-resistant and aging-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. 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 threaten...
