The invention discloses a photochromic
ceramic tile and a preparation method thereof. The preparation method comprises the steps of: A, preparation of ground
glaze: by
mass percentage, mixing 30-35% of
frit, 3-7% of a functional agent, 20-28% of
lithium porcelain stone, 5-10% of
zirconium silicate, 20-25% of kaolin and 10-12% of
quartz evenly, conducting wet ball-milling, and performing sieving to obtain
slurry ground
glaze; B, preparation of surface
glaze: by
mass percentage, mixing 70-80% of
frit, 1-4% of conductive
powder, 10-20% of kaolin, 5-8% of
alumina, 1-2% of
zinc oxide and 1-5% of
zirconium silicate evenly, performing wet ball-milling, and conducting sieving so as to obtain
slurry surface glaze; and C, applying the ground glaze and surface glaze prepared by step A and step B respectively to a tile blank in order, and performing firing so as to obtain the
ceramic tile. Compared with the existing
ceramic tiles, the ceramic tile prepared by the method provided by the invention has the characteristics of scientific compounding, reasonable preparation and stable performance. Also through reasonable
collocation with conductive
powder, photochromic compounds and antibacterial
powder, the ceramic tile has excellent antibacterial, antistatic and photochromic properties, thus further broadening the application scope of
ceramic tiles.
