CN105238156A - Low-roughness marine coating and manufacturing method thereof - Google Patents

Abstract

The invention discloses a low-roughness marine coating. The coating is prepared by mixing and dissolving chlorinated rubber and rosin, and adding coupling-agent-coated modified nanometer germanium oxide and other effective auxiliary agents at the same time; and all the components are uniformly dispersed, which enables the coating to have further reduced surface roughness and the characteristics of a smooth surface and low friction, and the components draw on each other's strength. Due to the composition of a C-Cl bond with great polarity, resistance to ozone and chemical mediums of the coating is 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 low-roughness marine coating provided by the invention can be applied to newly built and repaired offshore and ocean vessels, etc., and has good application prospects.
