Abstract

The invention discloses a marine coating with high weather resistance. The coating is prepared by mixing and dissolving chlorinated rubber and vinyl acetate resin, and adding coupling-agent-coated modified nanometer magnesium hydroxide and other effective auxiliary agents at the same time; and all the components are uniformly dispersed and draw on each other's strength. Due to the composition of a C-Cl bond with great polarity, weather resistance and flame retardation performance of the coating are increased, and the disadvantages of great brittleness, low toughness, poor adhesion on a substrate and the like of a chlorinated rubber coating are improved; meanwhile, added metal aluminum powder can significantly improve permeability and electrochemical corrosion resistance of the coating so as to effectively enhance durability and weather resistance of ships. The coating provided by the invention has the advantages of simple preparation process, few synthetic steps; and a film obtained after coating of the coating on a ship bottom is smooth and compact, does not fall off, has high glossiness and shows significant resistance reducing performance in water.
