Abstract

The invention discloses an environmental-crack-resistant low-temperature compensation cable material and its preparation method. The cable material comprises the following raw materials, by weight, 80-90 parts of methylvinyl silicone rubber, 35-45 parts of epichlorohydrin rubber, 20-30 parts of a polyolefin elastomer (POE) 8100/American DuPont, 25-35 parts of nano-attapulgite, 2-4 parts of precipitated white carbon black, 80-90 parts of nanometer pottery clay, 3-6 parts of a bisphenol A, 2-4 parts of a vulcanizing agent MOCA, 1-3 parts of an antioxidant MB, 2-5 parts of a silane coupling agent KH550, 1-3 parts of dibasic lead phosphite, 3-4 parts of an antioxidant 1010, 2-5 parts of ethylene bis-stearamide, 1-3 parts of chlorinated paraffin and 10-20 parts of magnesium hydroxide. The cable material has the advantages of simple preparation method, excellent electrical property, and good physical and mechanical performances, and can satisfy a requirement that the temperature changes under different environments.

Description

technical field [0001] The invention relates to an environment-cracking-resistant low-temperature compensation cable material and a preparation method thereof, belonging to the technical field of cable materials. Background technique [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, it releases a large amount of smoke and toxic and corrosive gas, which is a risk factor in a fire. It hinders people's safe evacuation and fire fighting work during a fire, causing serious loss of life and property. At the same time, with the development of the communication industry, automobile industry and computer industry, especially in many occasions such as aviation wires, automobile wires, high-temperature instrument cables,...
