Abstract

The invention discloses a metallic paint coating and a preparation method thereof. The preparation method comprises the following steps that a base material is coated with a primer layer; the primer layer is coated with a metallic paint layer, wherein the components of the metallic paint are waterborne polyurethane and metallic copper powder; the metallic paint layer is dried; the metallic paint layer is subjected to polishing treatment; the polished metallic paint layer is subjected to blackening treatment; oxidation treatment is performed on the metallic paint layer subjected to blackening treatment; and the oxidized metallic paint layer is coated with a transparent protective paint layer. According to the preparation method of the metallic paint coating, the coating is uniform and stable through reasonable proportion blending; then, through multi-layer polishing treatment, the core metallic paint layer presents perfect metallic texture; through chemical treatment, the metallic texture shows various changes to meet different requirements; and finally, the protective layer is used for protection, so that the service life is prolonged while the appearance purpose is achieved.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a metal paint coating and a preparation method thereof. Background technique [0002] Most building materials do not have corrosion resistance, so they need to be protected with coatings, but due to the material limitations of the coating itself, its appearance does not show much change. However, as the aesthetic level of Chinese people continues to improve, and the globalization of art under the background of economic globalization, the demand for new materials and technologies continues to increase. It has become a trend for materials to cross-border and integrate with each other; Consumption, conservation and environmental protection are also common difficulties faced by human beings. The application of efficient integration of new materials is the common goal of current enterprises. [0003] The metal appearance is very popular, because the metal appearance has a high orn...
