There are many ways to slow down corrosion, including corrosion resistant alloys, electroplating, cathodic protection, corrosion protection of coatings, etc. Wherein the corrosion prevention of the coating is the most widely economic and convenient corrosion prevention method. Compared with other methods, the coating has the advantages of convenient construction, low recoating and maintenance cost, no influence of the shape and the area of equipment to be protected, easy combination with other anticorrosion methods and the like. About 30% of metal resource loss can be avoided by the coating protection method, which is very considerable. Coating companies and institutions now make a great deal of research both domestically and abroad.
The domestic patent with the application number of CN201610639233.5 discloses a seawater corrosion resistant plastic coating, which comprises the following components in parts by weight: 15-25 parts of carrier, 5-10 parts of vinyl chloride-vinyl acetate copolymer, 0.5-1 part of nano silicon dioxide, 3-8 parts of silane coupling agent, 1-3 parts of fluorine-silicon water repellent, 12-25 parts of organic solvent, 5-25 parts of pigment and filler and 28-48 parts of auxiliary agent. According to the plastic paint disclosed by the invention, the modified acrylic resin is used as a carrier, and the vinyl chloride-vinyl acetate copolymer, the nano silicon dioxide, the silane coupling agent and the fluorine-silicon water repellent are added to modify the acrylic resin according to different addition ratios, so that the product has a better seawater corrosion resistance effect, and the related auxiliary agents and organic solvents are added, so that the permeability of a coating film is effectively reduced, the structure and the corrosion resistance of the coating film are further enhanced, and the plastic paint is suitable for the market demand of seawater corrosion resistance paint.
With the development of the marine related industry, the demand for corrosion resistant coatings is higher and higher, and therefore, it is necessary to develop corrosion resistant coatings with excellent performance.
The graphene has the advantages of large specific surface area, excellent conductivity, ultrahigh strength, toughness, shielding property and the like, so that the graphene has potential application prospects in anticorrosive coatings. The graphene can form a compact physical barrier layer on the metal surface and in the active medium, so that the passing of gas molecules such as water, oxygen and the like can be effectively blocked.

The scholars have applied the graphene/waterborne polyurethane nano composite emulsion and the graphene/polyurethane in-situ polymerized waterborne conductive coating to the field of corrosion prevention, but the graphene/waterborne polyurethane nano composite emulsion and the graphene/polyurethane in-situ polymerized waterborne conductive coating have the common defects that the graphene is prepared by reducing again, the preparation process is complex, and the corrosion prevention property cannot meet the use requirement under the marine condition.
