Description
Technical Field
The invention relates to the technical field of coatings, in particular to an underwater coated ship antifouling coating and a preparation method thereof.
Background
With the continuous development of economy, more and more underwater processes, the continuous development of marine oil, port and wharf, hydroelectric power stations and ship industries, the projects such as dikes, reservoirs, water gates, underwater pipelines and the like, and wet places such as mines, tunnels, bathing pools, hot springs, swimming pools, water storage tanks and underground storehouses and the like all need the heavy anticorrosive coating solidified in water, in addition, 18000 varieties of organisms in various sea areas in the world are attached animals, and 600 varieties of organisms are attached plants. After marine organisms attach to the bottom of the ship, resistance is increased, the speed is reduced, the fuel consumption is increased, and the mechanical abrasion is increased. The adhesion of marine life also damages paint film, accelerates the corrosion and damage of steel plate or hydraulic concrete structure, not only increases the maintenance times and time of the ship, but also reduces the aviation rate of the ship. For naval vessels, marine life greatly affects the speed of flight.
At present, antifouling paint is coated on ships and ocean engineering during construction, but the antifouling effect is generally 3-5 years, the maintenance period of large ships is 7-10 years, the design life of harbor engineering is 50-100 years, mechanical damage and failure of an antifouling coating cause local fouling in the use process, the balance and stability of the ships and ocean engineering are influenced, the attachment of fouling marine organisms not only increases the weight of a construction, but also causes the damage of a protective coating and accelerates the local corrosion of a base material, and the structure and safety of the ships and ocean engineering are influenced by the fouling organisms. The existing mature methods for preventing marine biofouling except the antifouling coating are electrolytic chlorine antifouling, underwater mechanical treatment and external protection sleeve treatment, but the electrolytic chlorine antifouling matching equipment is expensive and low in cost performance, so that the method is only suitable for special parts; the underwater mechanical treatment has high working strength and can not prevent the regrowth of marine organisms after the treatment; the additional protective sleeve is only suitable for a few steel pipe piles with regular appearances, only can prevent marine organisms at the tidal range area from growing, and the corrosion-resistant coating can be damaged under the action of friction to cause corrosion of a steel structure.
In order to prevent and remove marine organisms, the application of antifouling paint is the only economically and efficiently important way to solve the fouling problem and widely apply. However, the various coatings for underwater application have been prepared by using epoxy resins as a base material and using the epoxy resins as a solvent-free or high-solid coating. A plurality of common epoxy resin curing agents are available on the market, but epoxy coatings prepared by using the common epoxy resin curing agents react with carbon dioxide in water or air to generate carbonate when meeting water or a humid environment, so that a bonding layer is isolated by the carbonate, the adhesion force of the coating is extremely reduced, the coating is easy to fall off, and the corrosion resistance is poor.
