Method for preparing polished crystal tile

The invention discloses a method for preparing a polished crystal tile, comprising the following steps of: accumulating a mixture of low-temperature clinkers and high-temperature clinkers on a printed tile surface baked at high temperature; baking; and polishing. The polished crystal tile prepared with the preparation process has high high-temperature viscosity and stable glass network structure, the baked clinker has certain height and has stereoscopic impression and artistic feeling. The action of the skeleton of the high-temperature clinker is favorable to the discharge of bubbles, and the obtained enamel layer has few bubbles, high transparency and high enamel quality. By regulating the proportion of the low-temperature clinkers and the high-temperature clinkers, the preparation method is suitable for different baking temperatures, is convenient and flexible and is suitable for different products.
