according to the detection results of the embodiments 1 to 3, the comparison shows that the coating obtained according to the formula proportion of the embodiment 1 has the most excellent performance, the chlorosulfonated polyethylene, the chlorinated rubber and the styrene elastomer are mixed and modified, the sealing protection effect and the adhesive force are improved, the corrosion resistance of the coating is effectively improved in the ceramic whisker, the carbon nanotube, the ceramic powder and the ceramic whisker, the toughness, the hardness and the scratch resistance of the coating are improved, the weather resistance of the coating is effectively improved by the aluminum silver paste, and the sealing protection coating with excellent comprehensive performance is formed.
