Abstract

The present invention relates to a kind of metal surface lacquer with flip-flop effect and its preparation process. The metal surface lacquer with flip-flop effect is prepared with dispersive nanometer particle slurry with flip-flop effect together with polyester resin, amino resin, closed isocyanate modified resin, metal aluminum powder, pigment and stuffing, solvent and assistant, and through certain technological process. The present invention has nanometer particle dispersed homogeneously in paint, and the prepared metal surface lacquer has high brightness, low haze value, obvious flip-flop effect, excellent decoration effect, high scrape resistance, high stone attack resistance, high wear resistance and good ageing resistance. The lacquer is used for car surface, outer metal decoration, 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...
