High temperature resistance flaming-retardant silicone rubber cable material for electric power and preparing method thereof

Abstract

The invention discloses a high temperature resistance flaming-retardant silicone rubber cable material for electric power and a preparing method thereof. The high temperature resistance flaming-retardant silicone rubber cable material for the electric power is formed by following raw materials, by weight, 120-140 parts of methyl vinyl silicone rubber, 10-20 parts of chloroprene rubber, 8-12 parts of polyethylene glycol terephthalate, 4-5 parts of tri methylol propane tri methacrylate, 8-10 parts of magnesium hydrate, 40-50 parts of dicyclohexyl terephthalate, 6-7 parts of vinyl trimethoxy silane, 4-6 parts of NDZ-401 titanate coupling agents, 6-8 parts of organic antimony stabilizer, 5-7 parts of antioxygen, 50-60 parts of nano calcium carbonate, 8-10 parts of diisooctyl phenyl phosphate, 11-13 parts of tetrabromo-bisphenol A, 6-9 parts of polyoxyethylene polyoxy hydramine amidogen ether, 6-8 parts of demethyl siloxane, 4-5 parts of antimonous oxide, 7-9 parts of calcium stearate, 7-10 parts of carbon monofluoride and 8-12 parts of nanometer titania. According to the synergistic effect of the added antimonous oxide and chlorine elements of the chloroprene rubber, the flaming retardant property of the methyl vinyl silicone rubber is enhanced, due to the added polyethylene glycol terephthalate, the diisooctyl phenyl phosphate and the tetrabromo-bisphenol A, the high temperature resistant property of the silicon rubber is improved, the wear resistant property and the machining performance are improved at the same time, and the flexibility of the cable is improved.

Description

field of invention [0001] The invention relates to a cable material, in particular to a high-temperature-resistant and flame-retardant silicone rubber cable material for electric power and a preparation method thereof. Background technique [0002] With the continuous and rapid development of China's economy, wires and cables have been widely used in various industries, and it is the second largest industry in China after the automobile industry. Or erosion, causing the cable rubber surface to be damaged or lose its original performance, especially when used in an environment with long-term high temperature and complex geological conditions, its wear-resistant collision, temperature resistance, medium resistance, aging resistance, and flame retardancy cannot reach Demand, frequent electrical accidents, and with the further improvement of the country's electrical safety requirements, the quality of electrical wires and cables will become higher and higher.
