CN105238152A - Marine coating with excellent coating adaptability and manufacturing method thereof - Google Patents

Abstract

The invention discloses a marine coating with excellent coating adaptability. The coating is prepared by mixing and dissolving chlorinated rubber, rosin and terpene resin, and adding coupling-agent-coated modified nanometer cerium oxide 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, oxidation resistance and adhesion of the coating are increased and disadvantages like large brittleness and low toughness of a chlorinated rubber coating are improved; and added boron powder can significantly improve permeability of the coating so as to effectively enhance durability and weather resistance of ships. The coating prepared by using the method provided by the invention has excellent coating adaptability and is to paint; a coating film has high strength and a smooth surface and is hard to fall off; meanwhile, a ship shell coated with the coating can consistently remain bright and clean for many years on the voyage; and significant economic benefits are obtained.
