METHOD FOR PRODUCING SERICITE WITH HIGH PHOTOCATALYTIC ACTIVITY OF VISIBLE LIGHT, HIGH OPACITY AND ANTIMICROBIAL PROPERTY AND ITS SERICITE

摘要

The present invention relates to a method for preparing sericite with high photokinesis, hiding power, and antimicrobial properties in visible wavelength range where sunlight is not irradiated. The method for preparing sericite comprises the following steps: independently preparing colloidal silver and titanium dioxide source by using a sol-gel method; mixing sericite with the prepared colloidal silver and the titanium dioxide source to produce slurry; and crushing the slurry. Accordingly, the surface of the sericite is coated with silver, silver phosphate, and titanium dioxide. In the method for preparing sericite, a nanosilver solution and silver phosphate are simultaneously obtained during a colloidal silver preparation process, so that the method for preparing sericite can be competitive in a preparation process.
