The invention discloses an improved anti-pollution flashover composite paint and a manufacturing method thereof. The method comprises the following steps: acquiring a paint compound used for manufacturing the improved anti-pollution flashover composite paint, wherein the paint compound comprises fluorinated silicone rubber, fumed silica and an ablation-resistant compound; dissolving the paint compound with a solvent so as to obtain a dissolved solution; adding a leveling agent into the dissolved solution for a pre-reaction so as to obtain a pre-reacted compound; and adding a vulcanizing agent into the pre-reacted compound so as to obtain the improved anti-pollution flashover composite paint. The improved anti-pollution flashover composite paint and the manufacturing method thereof provided by the invention overcome the technical problems of poor cold resistance and short service life of traditional anti-pollution flashover composite paints.
