Boehmite digital glaze ink and preparation method thereof

The invention discloses boehmite digital glaze ink and a preparation method thereof, and the preparation method comprises the following steps: (1) in a stirring state, mixing a soluble aluminum salt solution, an alkali liquor, a niobium diselenide dispersion liquid and a surfactant, and carrying out a hydrothermal reaction to obtain a finished product slurry; (2) washing and drying the finished product slurry obtained in the step (1) to obtain a finished product solid material; (3) performing heat treatment on the finished product solid material obtained in the step (2), and grinding to obtain boehmite powder; and (4) mixing the boehmite powder obtained in the step (3) with a solvent, and grinding to obtain the boehmite digital glaze ink, the boehmite digital glaze ink prepared by the method has full color development on a glaze surface formed after digital glaze spraying printing, and meanwhile, the boehmite digital glaze ink has relatively strong wear resistance. 本发明公开了一种勃姆石数码釉墨水及其制备方法，其中制备方法包括以下步骤：(1)搅拌状态下
