Problems solved by technology

[0002] Ship waterproof coating refers to a kind of coating that the coating film formed by the coating can prevent the penetration of water, thereby preventing the corrosion of its ship products. Among the ship waterproof coatings, polyurethane is the main film-forming substance, and its strength is high. High efficiency, good water resistance, easy to use, and a wide range of applications. However, this kind of marine waterproof coating has poor adhesion and wear resistance, and some coating products are added with substances that enhance wear resistance, which significantly reduces the adhesion. efforts, resulting in poor product performance and cannot be widely used
