CERAMIC PLATE HAVING ANTI-COUNTERFEITING VISUAL EFFECT AND PREPARATION METHOD THEREFOR
The present invention discloses a ceramic plate having an anti-counterfeiting visual effect and preparation method therefor. The preparation method comprises the following steps: preparing a green body using green body powder; applying an overglaze on the surface of the green body; ink-jet printing a pattern on the surface of green body after being applied the overglaze; applying a protective glaze on the surface of the green body after being ink-jet printed the pattern; applying an anti-counterfeiting material on the surface of the green body after being applied the protective glaze; the raw material composition of the anti-counterfeiting material includes: in percentage by mass, 20% to 30% of titanite, 3% to 5% of high-refractive-index oxide, and 60% to 80% of a low-temperature glaze powder; firing the green body after being applied the anti-counterfeiting material, the titanite and the high-refractive-index oxide are wetted and wrapped by a molten liquid produced by melting the low-temperature glaze powder in a firing environment, and sunken into the protective glaze without generating opacification; and then polishing to obtain a ceramic plate having an anti-counterfeiting visual effect. The anti-counterfeiting visual effect is a visual effect in which a high-intensity refraction effect is achieved when the sight line direction is consistent with the path of reflected light, but no refraction effect is achieved when the sight line direction deviates from the path of reflected light.
