Fluorosilicone rubber cable material for coal mine cable and preparation method of cable material

Abstract

The invention relates to a fluorosilicone rubber cable material for a coal mine cable and a preparation method of the cable material. The cable material comprises the following raw materials: fluorosilicone rubber, methyl vinyl silicone rubber, precipitation-method white carbon black, light calcium carbonate, zinc oxide, magnesium oxide, stearic acid, an accelerator N, N-tetramethylthiuram disulfide, an antiager-2-mercapto benzimidazole, a vulcanizer-2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane, a flame retardant-ammonium polyphosphate, diphenyl silanediol, talcum powder and vaseline. According to the cable material, the advantages of the fluorosilicone rubber and the methyl vinyl silicone rubber as raw materials are combined, the performance of a conventional fluorosilicone rubber cable material is improved, the cable material has excellent performances such as friction and collision resistance, high and low temperature resistance, medium resistance, ageing resistance, flame retardance, waterproof and moistureproof properties, long service life and the like, the requirement of safety use in a coal mine in a special environment is met, and the preparation method of the cable material is simple in process and free of environmental pollution and three-waste emission.

Description

Technical field

[0001] The invention relates to the technical field of cable sheaths, in particular to a fluorosilicone rubber cable material for coal mine cables 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 are the second largest industry in China after the automobile industry. However, ordinary wires and cables are used in different environments due to friction and collision with other objects. Or erosion, leading to damage or loss of the original performance of the cable rubber surface, especially in the long-term wet, complex geological conditions used in coal mines, its wear-resistant collision, temperature, medium, aging, flame retardant performance Electrical accidents occur frequently when the demand is not met. In addition, as the country further improves the safety requirements of the coal mining industry, the quality of the w...
