Temperature-resistant damp-proof and insulating methyl vinyl silicone rubber cable material

Abstract

The invention relates to a cable material, and in particular relates to a temperature-resistant damp-proof and insulating methyl vinyl silicone rubber cable material. The cable material comprises the following raw materials in parts by weight: 30-34 parts of methyl vinyl silicone rubber, 23-26 parts of precipitated silica, 10-12 parts of polyvinylidene chloride, 20-23 parts of linear low density polyethylene, 2-3 parts of anti-aging agent KY-405, 1-2 parts of anti-aging agent MB, 3-4 parts of magnesium oxide, 4-5 parts of stearic acid, 1-2 parts of dibenzothiazyl disulfide DM, 2-3 parts of paraffin, 3-5 parts of vaseline, 30-34 parts of spraying carbon black, 14-18 parts of nano bauxite, 20-25 parts of butyl rubber (CBK139), 5-7 parts of tributyl citrate, 2-3 parts of sulphur, 2-3 parts of zinc oxide and 4-5 parts of auxiliary. The cable material integrates the advantages of the raw materials such as the methyl vinyl silicone rubber, the butyl rubber, the polyvinylidene chloride and the linear low density polyethylene; the performance of the traditional silicone rubber cable material is improved; the temperature-resistant damp-proof and insulating methyl vinyl silicone rubber cable material provided by the invention has excellent high-temperature and low-temperature resistance and water-proof and damp-proof performance, as well as good insulation performance, can be adapted to a specific application environment condition, and therefore is wide in market prospect.

Description

Technical field [0001] The invention relates to a cable material, in particular to a temperature-resistant and moisture-proof insulating methyl vinyl silicone 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 prope...

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.
