The invention provides fire-resistant silicone rubber. The fire-resistant silicone rubber comprises the following raw materials: silicone rubber, white carbon black, glass fiber, glass beads, aluminumhydroxide, magnesium hydroxide, copper oxide, a heat stabilize, refractory fillers, a vulcanizing agent, a catalyst and hydroxyl silicone oil, wherein the catalyst takes carbon black as a carrier andtakes palladium, tungsten and platinum as active components, and the mass ratio of the palladium to the tungsten to the platinum to the carbon black is 1:2:5:100; the refractory fillers comprise quartz sand, mica powder, talcum powder and basalt; and the heat stabilizer comprises calcium carbonate, magnesium stearate, calcium stearate, zinc oxide and phosphite ester. The sources of the raw materials are wide, the preparation method is simple, the cost is low, and the prepared silicone rubber has high fire-resistant and flame-retardant properties and can be widely applied.
