Problems solved by technology

[0002] When a ship travels in the ocean, it needs to face a marine environment with high salinity, many pollutants, and strong impact. If it is in this environment for a long time, it is easy to cause serious damage to the hull. Generally, the method of coating the hull with paint is used to alleviate this. However, it is difficult for ordinary coatings to take into account the adhesion, wear resistance and antifouling properties. At the same time, the hull is prone to deformation with the change of ocean temperature between day and night, which intensifies the peeling off of the coating from the surface of the ship. Therefore, it is necessary to develop a coating that has both High-performance coatings with high adhesion, high wear resistance, and pollution prevention are necessary
