Room temperature vulcanized silicone rubber composite material and preparation method thereof

The invention provides a preparation method of room temperature vulcanized silicone rubber material and a room temperature vulcanized silicone rubber material prepared by the provided method. The preparation method comprises the following steps: (1) under the crosslinking reaction conditions, subjecting a silicone rubber containing mixture, which comprises silicone rubber basic rubber, a crosslinking agent, and a first catalyst, to a crosslinking reaction so as to obtain a crosslinking product, wherein at least one end of the molecular chain of the silicone rubber basic rubber is an hydroxyl group, an alkoxyl group, or a vinyl group; (2) contacting the crosslinking product with a silicon dioxide precursor and a second catalyst to make at least part of the silicon dioxide precursor and the second catalyst enter the crosslinking product, and finally carrying out hydrolytic condensation reactions under hydrolytic condensation reaction conditions. The room temperature vulcanized silicone rubber composite material
