Abstract

The invention relates to a water-based ceramic ink for inkjet printing and its preparation method and application. The preparation method comprises: mixing ceramic colorant particles, a dispersant and a solvent, and stirring to obtain a slurry with a solid content of 32-35wt.%. , put the slurry in the grinding chamber; perform ultrafine grinding on the slurry to obtain d 50 =320‑394nm, d 90 =854‑954nm suspension; add wetting agent, resin, anti-sedimentation agent and solvent to the suspension, emulsify ultrasonically, and disperse at high speed to obtain water-based ceramic ink; the dispersant is based on methyl methacrylate, methyl Acrylic acid, 2‑acrylamido‑2‑methylpropanesulfonic acid and glycerol monomethacrylate as monomers, deionized water as solvent, thioglycolic acid as chain transfer agent, potassium persulfate as initiator . The water-based ceramic ink fully meets the requirements of inkjet printing, can decorate the surface of a ceramic plate, has good color rendering effect after decoration, and has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of ceramic ink and inkjet printing, and in particular relates to a water-based ceramic ink for inkjet printing and its preparation method and application. Background technique [0002] In the surface decoration industry of architectural ceramics (such as ceramic plates), the surface decoration technology of ceramics mainly includes inkjet printing, screen printing, roller printing and heat transfer film. At present, ceramic inkjet printing technology has partially replaced traditional decoration methods such as screen printing and roller printing. This ceramic surface decoration technology is a non-contact digital printing technology. Compared with traditional ceramic surface decoration technologies (such as screen printing and roller printing, etc.), ceramic inkjet printing technology has the characteristics of high degree of automation, simple process, and low energy consumption, which can effectively impr...
