[0002] Since the production process of glazed tiles is glazed on the green body layer and then fired, better raw materials are often used for the decorative effect of the glazed layer. In order to reduce costs, manufacturers mostly use cheap raw materials for the green body layer. The difference in the quality of the raw materials of the body layer leads to the difference in hue between the bottom and the face of the finished body, especially the obvious difference in whiteness and oxidation degree, which makes the color tone of the bottom surface of the finished ceramic tile different from that of the side and top surface, which gives Customers have a feeling of "two skins, different appearances", which affects product sales

[0028] A method for preparing ceramic high-whiteness glazed tiles, comprising the following steps:
[0029] A. Prepare the whitening glaze according to the ratio of whitening glaze raw materials, wherein the raw material of the whitening glaze includes titanium frit, and the cohesive force of the whitening glaze is ≥0.1MPa;
[0030] B. Put the surface glaze raw materials into the ball mill according to the ratio and ball mill to obtain the surface glaze;
[0031] C. Apply the top glaze of step B to the upper surface of the ceramic brick body 2 to form a top glaze layer 3;
[0032] D. Apply the whitening glaze in step A to the bottom surface and / or side of the ceramic tile body in step C to form a whitening glaze layer 1, wherein the melting temperature of the whitening glaze is the same as that of the ceramic tile body 2 The difference between the melting temperature of the whitening glaze is ≤3°C, and the difference between the expansion coefficient of the whitening glaze an...

Abstract
The invention discloses a preparation method of a ceramic high-whiteness glazed tile, and the prepared ceramic high-whiteness glazed tile. The preparation method of the ceramic high-whiteness glazed tile comprises the following steps: A, preparing whitening glaze from whitening glaze raw materials in proportion; B, obtaining surface glaze; C, applying the cover glaze obtained in step B to the upper surface of a ceramic tile blank to form a cover glaze layer; D, applying the whitening glaze obtained in step A to the bottom surface and / or the side surface of the ceramic tile blank obtained in step C to form a whitening glaze layer; and E, drying and firing the ceramic tile blank obtained in step D to form the ceramic high-whiteness glazed tile. The preparation method of the ceramic high-whiteness glazed tile is beneficial to preventing the whitening glaze from falling off. According to the ceramic high-whiteness glazed tile prepared by the preparation method of the ceramic high-whitenessglazed tile, the whitening glaze is applied to the tile body, so that the bottom surface hue of the glazed tile finished product is consistent with the hue of the side surface and / or the top surfaceof the glazed tile finished product, and the improvement of the green brick whiteness of the glazed tile is facilitated.
