The invention relates to the technical field of leather, in particular to temperature-resistant silica gel leather and a preparation method thereof. The temperature-resistant silica gel leather comprises textile base cloth and a coating layer coating the textile base cloth, wherein the coating layer is made of a silica gel material, and the silica gel material comprises the following raw materials of, in parts by weight, 0-35 parts of vinyl MQ silicon resin, 0.1-0.5 part of a platinum complex catalyst, 2-6 parts of modified aluminum hydroxide, 0-5 parts of polymethyl silicate, 2-6 parts of a silanization reagent, 0.2-0.6 part of butyl titanate, 8-16 parts of a filling agent, 100-130 parts of basic gel, 1-3 parts of distilled water, 0-10 parts of a cross-linking agent, 0.1-0.5 part of a stabilizer and 0.5-1.5 parts of a coupling agent. According to the silica gel leather, under the condition that a flame retardant is not needed, a leather product can have very good flame retardance and fire resistance, has goo
