A kind of pigment for ceramic inkjet printing and preparation method thereof

Abstract

The invention discloses a color material for ceramic ink-jet printing and a preparation method thereof. The preparation method comprises the following steps of A, mixing a color material raw material and oxysalt composite fluxing agent with water to prepare a solution; B, uniformly stirring and heating the solution at the temperature of 150 to 500 DEG C, and preserving the heat for 1h to 3h; C, naturally cooling reactant to the room temperature after the heat preservation is completed, adding deionized water for washing and filtering the reactant to obtain solids; D, drying the solids, and calcining the solids to prepare a color material finished product, wherein the drying temperature is 100 to 150 DEG C, and the calcining temperature is 900 to 1100 DEG C. The color material particle is in similar spherical shape, solid, small in granularity and narrow in granularity distribution, and the principal crystalline phase is not deviated in chemometry; after the color material is ground into sub-micrometer, the regular appearance of the color material still can be maintained; the ink prepared by utilizing the color material is good in stability and color development, and the ink is free from abrading and blocking a nozzle in real production.

Description

technical field

[0001] The invention relates to the field of inkjet printing, in particular to a color material for inkjet printing of ceramics and a preparation method thereof. Background technique

[0002] Inkjet printing technology for ceramic decoration is a decoration method in which multi-color ink made of ceramic pigments is printed onto the surface of the medium through a nozzle through a computer control system, and then colored after firing. With the increasing demand for ceramic ink, ceramic ink products have gradually entered the industrialization, but the products on the market often encounter problems such as clogged nozzles, ink hanging, and poor color development during use. In the final analysis, the ceramic inks on the market are generally prepared by the dispersion method. The ink color material needs to be ground to submicron level, it is difficult to control the particle size distribution, and impurities are easily introduced during the grinding process,...
