In June 2003, Japan invented a new process for the production of colored mica, which is characterized by the application of a pigment-containing metal oxide gel on the surface of mica or metal oxide-coated mica to form a colored vitreous gel layer. That is, the pigment is dispersed in the metal alkoxide, a polyvinyl alcohol resin dispersant and an alcohol solvent are added to prepare a coating solution, which is coated on the surface of the mica, and is maintained at about 150 degrees Celsius, so that the sol becomes a gel to form a solid coloring gel Film. According to reports, colored mica made by this process is weather resistant, heat-resistant, alkali-resistant, and solvent-resistant, and its degree of freedom of coloring is extremely high, which effectively improves the use effect.
Colored mica as a pearlescent colorant is widely used in coatings, decoration and cosmetics, plastics, inks, ceramics and other industries. At present, colored mica is generally made by a composite process of coating metal oxides on the surface of mica, but its use effect is not very satisfactory.
