Abstract

The invention discloses a silicone rubber insulating fluororubber cable material and a preparation method thereof. The silicone rubber insulating fluororubber cable material comprises the following raw materials in parts by weight: 90-100 parts of methyl vinyl silicone rubber, 20-30 parts of magnesium hydroxide, 40-60 parts of SBS (Styrene Butadiene styrene), 50-60 parts of ethylene-vinyl acetate copolymer, 20-30 parts of polytetrafluoroethylene, 1-4 parts of precipitated white carbon black, 60-80 parts of light calcium carbonate, 2-4 parts of 2,4-dichlorobenzoyl, 3-5 parts of accelerant DM, 3-6 parts of 2-thiolbenzimidazole, 1-3 parts of cross-linking agent TAC, 2-4 parts of calcium stearate, 2-4 parts of antioxidant DSTP, 1-5 parts of stearoyl-rac-glycerol, 2-5 parts of stearic acid and 10-20 parts of ammonium polyphosphate. According to the invention, the preparation method is simple, the electric performance is superior, the formula of the raw materials is rational, and the prepared cable material is environment-friendly, has the advantages of softness, wear resistance, watertightness and the like, and passes the A-level fire resistance test in China.

Description

technical field [0001] The invention relates to a silicone rubber insulating fluorine rubber 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, the automobile industry and the computer industry, especially in many occasions such as aviation wires, automobile wires, high-temperature instrument cables, and oil d...
