Wear-resistant liquid silica gel composite material and preparation method thereof

The invention relates to the technical field of silica gel materials, and particularly provides a wear-resistant liquid silica gel composite material and a preparation method thereof. The liquid silica gel composite material is prepared from the following components in parts by weight: 40 to 60 parts of dimethyl siloxane, 10 to 20 parts of methyl vinyl silicone rubber, 5 to 8 parts of vinyl trimethoxy silane, 2 to 5 parts of biomass graphene, 1 to 3 parts of polytetrafluoroethylene micro powder, 1 to 3 parts of silicon quantum dots, 0.5 to 2 parts of nano titanium dioxide and 1 to 3 parts of heat stabilizer. According to the invention, nano materials such as biomass graphene, polytetrafluoroethylene micro powder, silicon quantum dots and nano titanium dioxide are introduced into a traditional liquid silica gel material, and a plurality of nano materials have a synergistic effect, so that the wear resistance and mechanical strength of the composite material are remarkably improved while the flexibility and tra
