Abstract

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.

Description

technical field [0001] The invention relates to the technical field of silicone rubber, in particular to a fire-resistant silicone rubber. Background technique [0002] Silicone rubber is an excellent special rubber. It has excellent heat resistance, low temperature resistance, insulation, shock resistance, compression resistance, wear resistance and good biological characteristics, so that it has a wide range of applications. Silicone rubber itself is not refractory. However, in the current fire accidents, there is a problem that wires and cables are not fire-resistant and easy to burn in case of fire. This field lacks a fire-resistant silicone rubber, which is required to play a certain protective role in the fire and reduce the losses brought to people in the fire. , to reduce harm. A kind of fire-resistant silicone rubber is required, which can play a certain protective role in the fire, reduce the loss caused by the fire, and reduce the harm of electricity. Contents...
