A preparation method comprises the following steps: firstly preparingmaterials according to the ingredients, uniformly mixing on a mixer by adopting a melting and heat mixing method, and then vulcanizing, so that the silicone rubber-based composite material is obtained. the method provided by the invention has the advantages that the liquid crystal polymers can be fibrillated into a fibrous structure in a processing process, anchoring effect is achieved, mechanicalproperties of the silicone rubber-based composite material are improved, and the development requirement that the future silicone rubber-based composite material gives consideration to flame retardance, heat resistance, low density and high strength at the same time.
