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.
