Problems solved by technology

[0003] At present, there are patent reports and related products of ceramic inks of various colors on the market, but there are few white ceramic inks, and there are few researches and reports on ceramic white inks. The main problem is the preparation of nano-scale glazes. After printing ink, because the glaze is finer and the amount of glaze applied is not as much as that of the traditional printing process, the color will become transparent after sintering, and the whiteness of the final color is not enough, so it becomes the ceramic white ink. a technical difficulty

preparation example Construction

[0037] The preparation method of above-mentioned ceramic ink-jet printing white glaze ink, comprises the following steps:

[0038] 1) Mix part of the solvent, resin, dispersant and ceramic glaze, disperse evenly, and make the glaze fully wet;

[0039] 2) Grinding the dispersed glaze, controlling the average particle size of the glaze to be 200-400 nm, and the maximum particle size is less than 900 nm, to obtain glaze slurry;

[0040] 3) Add leveling agent, defoamer, anti-sedimentation agent and remaining solvent to the glaze slurry, and filter to obtain white glaze ink for ceramic inkjet printing.

Abstract

The invention discloses a white glaze printing ink for ceramic ink-jet printing and preparation method thereof, wherein the printing ink comprises, based on the mass percentage, 30-60% of white ceramic glaze, 3-10% of dispersant, 2-8% of resin, 0.1-0.2% of leveling agent, 0.3-0.7% of antifoaming agent, 0.08-0.12% of anti-settling agent, and the balance for the solvent. Wherein the white glaze includes, based on the mass percentage, 40 - 55% of SiO2, 38 - 15% of Al2O, 4 - 8% of (K2O + Na2O), 6 - 10% of (CaO + MgO), 3 -8% of ZrSiO4, 6 - 10% of B2O3, 6- 8% of ZnO, and 9 - 12% of CeO2. The viscosity of the printing ink prepared by the invention is low, and the distribution of particle size is uniform, and the viscosity is between 10.0 - 30.0mPa.s and adjustable, and the surface tension is 28 - 35mN / m, and the average particle diameter is 200 -400nm, and the maximum particle size less than 900 nm. The ceramic white glaze printing ink prepared by the invention has advantages of good quality stability, long-time preservation, and good performance of ink-jet printing, and realizes the preparation of white glaze printing ink for ceramic jet-printing.

Description

Technical field [0001] The present invention belongs to the field of ceramic inkjet technology, involving a white glazed ink and preparation method for ceramic inkjet printing. Background technique [0002] Ceramic inkjet technology is a non -contact digital printing technology. It is made of ceramic color powder into a multi -color ink, spraying small ink droplets from a nozzle of tens of microns to the surface of the building ceramics and burning it into the surface of the building.The decorative technique of the rear, the shape and geometry of the decorative pattern are controlled by the computer.Ceramic inkjetting technology abandons the tediousness of traditional printing methods (such as silk net prints and rolling prints), spray printing directly on the body, improves the precision of printing, and the image produced is more realistic and closer to nature. [0003] At present, there are already various colors of ceramic ink patent reports and related products, but there ar...
