Abstract

The invention discloses a high heat-resistant anti-aging cable material. The high heat-resistant anti-aging cable material is prepared from the following raw materials in parts by weight: Buna-N rubber, ethylene propylene rubber, linear low density polyethylene, fluorocarbon resin, hydroxyl silicone oil, modified attapulgite, graphene, ammonium polyphosphate, glass fibre, vermiculite, sodium silicate, nickel, chromium, calcium carbonate, nano-silicon dioxide, ethylene glycol, nano-silicon nitride, sulphur, a stabilizer, a plasticizer, a fire retardant and silicone oil. The invention further discloses a preparation method for the cable material. The cable material is wide in raw material source, simple in preparation process, low in production cost, and suitable for large-scale industrial production; according to the cable material, the Buna-N rubber, the ethylene propylene rubber and the fluorocarbon resin are matched for use, so that the compatibility is high; moreover, the sulphur is adopted to serve as a vulcanizing agent and is matched with the modified attapulgite, the silicone oil, the stabilizer, the plasticizer and the fire retardant, so that the heat resistance, the wear resistance, the oil resistance, the tear resistance and the compressive deformation property of the prepared cable material are excellent; the service life is long; the application range is wide.

Description

technical field [0001] The invention relates to a cable material, in particular to a high heat-resistant and aging-resistant cable material. Background technique [0002] With the development of economy and society and the continuous expansion of production, people's requirements for material living standards are also getting higher and higher, among which, the demand for electricity is also increasing. Electric power is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. 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 prom...
