Abstract

The invention discloses a heat-resistant anti-aging cable sheath material, comprising the following raw materials in parts by weight: 30-40 parts of poly-stabilizer-nitrile butadiene rubber, 20-30 parts of hydrogenated butadiene-acrylonitrile rubber, 5-8 parts of magnesium oxide, 8-13 parts of calcined clay, 8-10 parts of calcium carbonate, 2-5 parts of chlorinated paraffin, 0.2-0.3 part of phthalocyanine blue, 14-17 parts of white carbon black, 13-18 parts of organic montmorillonite, 1.5-3 parts of DOP (Dioctyl-Phthalate) softener, 0.7-1.3 parts of accelerant DM, 0.5-1.2 parts of accelerant TMTD and 0.5-0.9 part of sulphur. The heat-resistant anti-aging cable sheath material disclosed by the invention is excellent in heat resistance, abrasive resistance, oil resistance, tear resistance and compression deformation performance, and can be applied to a relatively harsh environment, and the service life is obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of sheath materials, in particular to a heat-resistant and anti-aging cable sheath material and a preparation method thereof. Background technique [0002] Wires and cables are widely used in various fields as electric energy and information transmission bodies. Most wires and cables use plastic and rubber as insulation and sheath materials. Such polymer materials will produce flammable gases after being heated, melted and decomposed. At high temperature, these gases will react with oxygen and burn, which will generate a lot of heat, and the heat will promote the further melting, decomposition and continuous burning of the polymer, which will expand the fire and cause huge losses. In my country, the fire loss caused by cables alone is as high as several billion yuan per year. As the flame retardant of wires and cables has attracted more and more attention, people have begun to study various flame retardant ...
