Abstract

The invention relates to a metal topcoat with an angle-dependent color effect and a preparation method thereof. The present invention adopts stable and transparent nano-particle dispersion slurry with color-dependent effect, and polyester resin, amino resin, blocked isocyanate modified resin, metal aluminum powder, other pigments and fillers, solvents, and additives In combination, a certain preparation process is used to prepare a metal topcoat with a color-dependent effect. By adopting the method provided by the invention, the nanoparticles are evenly dispersed in the paint, and the prepared metal topcoat has high gloss and low haze value, and has obvious color flop effect and good decoration, scratch resistance and stone chip resistance Resistance, abrasion resistance and aging resistance. Used in car topcoat, metal exterior decoration paint, etc.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a metal topcoat with an angle-dependent color effect and a preparation method thereof. Background of the invention [0002] The high-grade and high-performance requirements of automobiles force the development of automobile coatings to continuously improve their protection and decoration performance. The main focus is to improve the decoration of the car surface, improve the scratch resistance and anti-corrosion ability, and better protect the environment, especially the surface protection and decoration layer of the car body, which directly affects the appearance and appreciation of the whole car. [0003] The research and development and industrialization of nano-materials for modified automotive coatings started earlier in the United States and Germany, and the research and development of nano-modified automotive coatings started relatively late in China. CN1189522A, a patent fo...
