Abstract

The invention relates to ink for ink-jet printing and a preparation method of ink, which belongs to the technical field of ceramic ink. The invention aims at solving the technical problem of providinga preparation method of the ink for the ink-jet printing. The preparation method comprises the following steps: dissolving polymethyl methacrylate in an organic solvent, adding praseodymium oxide nano particles, uniformly stirring, spray drying, and obtaining composite praseodymium oxide nano particles; uniformly mixing the composite praseodymium oxide nano particles, inorganic borate, solid suspension and solvent, grinding into pulp, adding a functional additive, solvent and distilled water, uniformly mixing, filtering, and obtaining the ink for the ink-jet printing. The method is simple, the cost is low, the prepared ink is high in color development capacity and is firmly combined with a substrate material; and moreover, the praseodymium oxide is coated by virtue of the polymethyl methacrylate, so that the dispersity in the ink is improved, the ink is unlikely in blockage in a printing process, and the ink can be widely applied to the ink-jet printing.

Description

technical field [0001] The invention relates to an ink for inkjet printing and a preparation method thereof, belonging to the technical field of ceramic ink. Background technique [0002] Ceramic inkjet printing technology is a kind of ceramic ink made by grinding inorganic ceramic pigments to the nanometer level, and then printed on the surface of ceramic tiles by ceramic inkjet printers to achieve the purpose of decoration. Inkjet printing technology has grown from scratch, and then from existence to near saturation in 2015. In just a few years, inkjet printing technology has developed so rapidly. The real reason is that ceramic inkjet printing technology is more advanced than traditional screen printing technology. , Roller printing technology has incomparable advantages. Ceramic inkjet printing technology is a new type of ceramic tile printing technology without contact, pressure and plate. It has the following advantages: (1) The speed of production change is fast and...
