Ocean antifouling paint used on surfaces of ships

Abstract

The invention discloses ocean antifouling paint used on surfaces of ships. The ocean antifouling paint is prepared from the following raw materials in parts by weight: 10-20 parts of epoxy resin, 10-30 parts of UV curing resin, 10-30 parts of UV cured monomer mixture I, 5-20 parts of curing agent, 1-10 parts of curing accelerator, 3-10 parts of flexibilizer, 2-5 parts of photoinitiator, 30-50 parts of mixed solvent I, 2-9 parts of additive and 0.9-5 parts of adhesion promoter. The ocean antifouling paint is free of pollution, short in construction time and high in paint film fullness degree, can be cured in a cross-linking manner, and is very high in cross-linking strength, high in hardness, good in scratching resistance, good in surface stability and excellent in resistance. The paint film can be used on surfaces of high / low speed ships and has a long-lasting antifouling effect.

Description

technical field [0001] The invention relates to a marine antifouling paint used on the surface of ships. Background technique [0002] The fouling of marine organisms on the surface of ships often increases navigation resistance, reduces navigation speed, and increases fuel consumption. Therefore, reducing the adhesion of fouling on the surface of ships has become a hot spot in the research of coating materials. The antifouling mechanism of traditional fluorocarbon antifouling coatings is based on the low surface energy physical effect on the surface of the coating. It is difficult for marine organisms to adhere, and even if they adhere, they are not firm. When the ship is running at high speed, it is easy to be washed off by the water flow. , avoiding the release of toxic substances from traditional toxic coatings. The current research and development of marine fluorocarbon antifouling coatings, or the development of some photocurable fluorocarbon acrylate monomers or res...

AI Technical Summary

Problems solved by technology

However, the currently developed fluorocarbon antifouling coatings are mostly used in high-speed docks, and they need to be cleaned regularly, otherwise the fouling bioadhesion will grow and it will be difficult to remove

At present, the existing research only focuses on the low surface energy antifouling effect of fluorocarbon coatings, and it is difficult to fundamentally solve the problem of ship surface fouling

In addition, cleaning, scratching and damage of the coating surface often lead to the reduction of antifouling effect; and for fluorocarbon polymer series coatings, the poor compactness of the coating and the molecular reconstruction of the coating surface induced during the adhesion process also lead to the reduction of the antifouling effect of the coating. These problems restrict the application of fluorocarbon coatings in the field of marine antifouling

Therefore, the preparation of efficient and broad-spectrum fluorocarbon marine antifouling coatings is extremely challenging
