Problems solved by technology

[0002] The marine environment is a very harsh and corrosive environment. The air above the ocean has high humidity and contains a lot of salt. The cabin of the ship has been in such an environment for a long time, and the corrosion is extremely serious, which poses a serious hazard to safe production. At the same time, the hull Changes in temperature between day and night are prone to deformation, which exacerbates the peeling of the coating from the cabin surface. At present, there are many anti-corrosion cabin coatings on the market. However, these coatings are not high in strength and adhesion, and cannot meet the requirements of the cabin coating in the shipbuilding industry. Require
