The invention relates to the technical field of silicone rubber, in particular to fireproof arc-resistant silicone rubber and a preparation method thereof, and a fireproof arc-resistant adhesive tape. The fireproof arc-resistant silicone rubber comprises the following raw materials in parts by weight: 70-75 parts of methyl vinyl silicone rubber A, 15-25 parts of methyl vinyl silicone rubber B, 0-0.5 part of a platinum complex flame retardant, 35-40 parts of fumed silica, 5-10 parts of vinyl silicone oil, 8-12 parts of a structure control agent, 1-5 parts of a silane coupling agent, 20-30 parts of aluminum hydroxide, 35-55 parts of a filler, 1-5 parts of magnesium oxide and 1-1.5 parts of a cross-linking agent. The fireproof arc-resistant silicone rubber is light and thin, and has good fire resistance, fire resistance, compressive strength and arc resistance; the preparation method is simple; and the fireproof arc-resistant rubber tape prepared from the fireproof arc-resistant silicone rubber has good fire res
