[0002] Water-based aluminum pigments can be evenly dispersed in water-based coating systems. They also have certain corrosion resistance and are not prone to "gassing".

[0003] With the development of the times, a single silver-white aluminum pigment cannot meet people's demand for aluminum pigments. Colored aluminum pigments not only maintain the metallic texture of the aluminum pigment itself, but also present brilliant colors. By coating one or more layers of inorganic substances on the surface of the aluminum pigment, a firmly colored colored aluminum pigment is obtained under chemical bonding.

[0004] The traditional method for preparing colored aluminum pigments is to simply physically blend aluminum pigments with organic pigments and then add them to resin to make a color paste for use. However, the colored aluminum pigments prepared in this way will inevitably face the problems of poor color and powder falling due to uneven mixing or low adhesion. In order to improve the adhesion of the pigment, a colored aluminum pigment with metallic luster and strong coloring is prepared. Utility Model Content
