Rare earth functional ceramic ink as well as preparation method and production method thereof

The invention provides rare earth functional ceramic ink as well as a preparation method and a production method thereof. The preparation method of the rare earth functional ceramic ink comprises the following steps: weighing photochromic rare earth oxide, a solvent and a hyperdispersant in a stirring machine according to a ratio being (15-30) to (71-85) to (0.3-6), mixing and stirring to obtain a mixture; putting the obtained mixture in a sanding machine, and sanding; and carrying out filtering on the obtained sanded mixture for deironing, so that the rare earth functional ceramic ink is obtained. The rare earth functional ceramic ink is prepared by introducing a rare earth element and combining an optimized ceramic powder modification treatment process, so that the prepared rare earth functional ceramic ink has the characteristics of good dispersibility, high stability and simplicity in preparation method and is applicable to ink jet printing. By adopting the rare earth functional ceramic ink provided by the invention, the function of existing printing ink is enriched.
