The invention discloses a high-performance anti-tracking silicone rubber and a preparation method thereof. In parts by mass, the raw material composition of the anti-tracking silicone rubber is: 100 parts of methyl vinyl silicone rubber, 20-45 parts of fumed silica, 4-15 parts of hydroxyl silicone oil, 0.3-1 part of hydrogen-containing silicone oil, 0.5-5 parts of nitrogen-containing silane, 0.1-2 parts of platinum compound and 0.5-4 parts of 2,5-dimethyl-2,5-di-tert-butylperoxyhexane. During preparation, mix methyl vinyl silicone rubber, fumed silica, hydroxyl silicone oil, and hydrogen-containing silicone oil in a kneader at room temperature, and heat-treat to obtain a silicone rubber base rubber; mix the base rubber and other components of the formula Mix evenly on the open mill, and then vulcanize in stages. The silicone rubber of the invention has excellent tracking resistance and mechanical properties, and can be applied in the field of high-voltage insulation; and the raw materials are easy to obtain, the processing technology is simple, and it is convenient for large-scale production.
