Abstract

The invention discloses an environment-friendly marine coating. The coating is prepared by mixing and dissolving chlorinated rubber, bisphenol-A epoxy resin and acrylic resin, and adding coupling-agent-coated modified nanometer zinc 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, light resistance and outdoor aging resistance of the coating are increased, and the disadvantages of great brittleness, low toughness, poor adhesion on a substrate material and the like of a chlorinated rubber coating are improved; meanwhile, added metal magnesium 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 is simple to prepare and uses simple and easily-available raw materials; and the prepared coating is friendly to the environment, has a certain antifouling effect, can be extensively applied to ships, wharfs, marine engineering facilities and relative fields, can alleviate pollution to the marine environment to a great extent, and has high economic benefits and social benefits.
