Problems solved by technology

It is prone to the problem that wires and cables are not fire-resistant and easy to burn in case of fire. 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.
The conductivity of general silicone rubber can meet the requirements, but such as ignition coils, it is required not only to have conductivity, but also to have fire resistance similar to metals. At present, general conductive silicone rubber cannot meet this technical requirement.

Description

technical field [0001] The invention relates to the technical field of silicone rubber, in particular to a fire-resistant conductive silicone rubber composition. 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. It is prone to the problem that wires and cables are not fire-resistant and easy to burn in case of fire. 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. The conductivity of general silicone rubber can meet the requirements, but such as ignition coils, it is required not only to have conductivity, but also to have fire resistance similar to metal.
