The invention relates to the technical field of silicone rubber, in particular to temperature-resistant insulating silicone rubber, a preparation method thereof and a temperature-resistant insulating adhesive tape. The temperature-resistant insulating silicone rubber comprises the following raw materials in parts by weight: 50 parts of methyl vinyl silicone rubber A, 35-45 parts of methyl vinyl silicone rubber B, 10-15 parts of methyl silicone resin, 45-50 parts of fumed silica, 12.5-15.5 parts of a structure control agent, 1.8-2.2 parts of a cross-linking agent, 10-45 parts of aluminum hydroxide, 45-70 parts of a filling agent, 3-5 parts of nano titanium dioxide and 2.5-4 parts of a vulcanizing agent. The temperature-resistant insulating silicone rubber disclosed by the invention has good mechanical properties, thermal stability and tracking resistance, good insulativity and long service life; the preparation method of the temperature-resistant insulating silicone rubber is simple, convenient to operate and
