The invention belongs to the technical field of ceramics, and particularly relates to an anion easy-cleaning functional
ceramic additive and a preparation method thereof, a
ceramic prepared by using the additive and a preparation method thereof. The additive is prepared from the following raw materials in percentage by
mass: 10-16% of Chongguang stones with a particle size of 5-20 microns, 16-25% of
tourmaline with a particle size of 5-15 microns, 5-15% of
copper pectolite with a particle size of 5-20 microns, 8-12% of nano
titanium dioxide, 6-8% of
nano zinc oxide, 5-10% of lead-free frits, 7-20% of
rare earth materials, 8-10% of superfine
alumina, 8-15% of superfine
quartz powder and 5-10% of
sodium carbonate. The preparation method of the additive comprises the following steps of carrying out mixed ball-milling on the lead-free frits, the
rare earth materials, the superfine
alumina, the superfine
quartz powder and the
sodium carbonate firstly; and then, adding the Chongguang stones, the
tourmaline, the
copper pectolite, the nano
titanium dioxide and the
nano zinc oxide into the obtained product, and ball-milling the obtained mixture, so that the additive with a particle size of 1-10 microns is obtained. The additive disclosed by the invention has a self-polarizing performance, and has strong adsorption and
decomposition functions, so that negative ions are produced; and after the additive is added into a
ceramic, the ceramic is extremely easy to clean and not stained, and has no hidden
dirt, therefore, the ceramic has a strong affinity to water.
