Problems solved by technology

[0003] Waterproof coating for construction machinery refers to a kind of coating that the coating film formed by the coating can prevent the penetration of water, thereby preventing the erosion of its construction machinery products. Among the waterproof coatings for construction machinery, polyurethane is the main film-forming substance. High, high elongation, good water resistance, easy to use, and a wide range of applications. However, this kind of construction machinery waterproof coating has poor adhesion and wear resistance, and some coating products are added with substances that enhance wear resistance. Significantly reduces adhesion, resulting in poor product performance and cannot be widely used
