Abstract

The invention provides a highly wear-resistant, weather-resistant and corrosion-resistant coating for locomotives, a preparation method and application thereof. The high wear-resistant, weather-resistant and corrosion-resistant coating for locomotives includes components A and B, and the component A comprises: hyperbranched modified aspartic acid resin 20-40, polyurethane acrylate 5-10 , polyacrylate 20-30, leveling agent 0.1-1.5, defoamer 0.1-1, the B component includes: isocyanate 50-80, active nano-silica with core-shell structure 10-30, light stabilizer 0.5 -1.5. The preparation method includes steps: (1) Weighing and mixing the materials uniformly according to parts by weight to obtain component A and component B; (2) filling component A and component B into Store in their respective containers, airtight. The high wear-resistant, weather-resistant and corrosion-resistant paint for locomotives of the invention can be used for primers, intermediate paints and top coats of locomotives. The product of the invention reduces the wear and tear on equipment, and also ensures the final protective performance of the coating.

Description

technical field [0001] The invention relates to the field of locomotive paints, in particular to a highly wear-resistant, weather-resistant, and corrosion-resistant paint for locomotives, a preparation method and an application thereof. Background technique [0002] In recent years, cars have become an important part of people's lives. The protective paint on the car mainly protects the surface of the car body and prevents the car body from being corroded by rainwater to prolong the service life of the car. [0003] The role of automotive coatings: (1) Beautify the appearance of the car: the paint film is required to be full and have a good metallic feel; (2) It is convenient for construction: automotive paints are generally multi-layer coatings, because single-layer coatings generally cannot achieve good quality. (3) Excellent mechanical properties: to adapt to the high speed, multiple shocks and strains of automobiles, it is required that the paint film has good adhesion,...
