Problems solved by technology

[0003] At present, in many fields, especially the automobile field, the demand for metallic paint is increasing, and the existing metallic paint contains formaldehyde, which will affect human health during use
At the same time, the existing metallic paint is not enough in terms of scratch resistance, so that a slight scratch will leave irreversible scratches on the paint surface
[0004] Chinese patent CN101215438A discloses an anti-fouling and anti-aging stainless steel coating and its preparation method. The coating is formed by mixing acrylic resin, film former, filler, solvent and auxiliary agent, wherein the film former includes fluororesin, water-based polyurethane, Epoxy resin, the filler contains nano-silica, the prepared coating has good aging resistance and UV resistance, but its scratch resistance is not good, which affects its service life and comprehensive performance

Description

technical field [0001] The invention belongs to the field of coating materials, in particular to an aging-resistant steel surface coating material and a preparation method thereof. Background technique [0002] With the wide application of metal materials, the demand for metal surface paint is also increasing. Some of them need to be coated with paint on the surface in order to resist harsh environments, such as high temperature resistance, cold resistance, ultraviolet resistance, corrosion resistance, etc., and some are In order to play a beautiful role. [0003] At present, in many fields, especially the automobile field, the demand for metallic paint is increasing, and the existing metallic paint contains formaldehyde, which will affect human health during use. At the same time, the existing metallic paint is not enough in scratch resistance, so that a slight scratch will leave irreversible scratches on the paint surface. [0004] Chinese patent CN101215438A discloses a...
