Abstract

The invention discloses an ink for ceramic ink-jet printing and a method for preparing the same, wherein the ink comprises the following components by mass percent: 20-50% of ceramic pigment, 3-8% of resin, 2-10% of dispersant, 0.1-0.2% of flatting agent, 0.3-0.7% of defoamer, 0.08-0.12% of anti-settling agent and the balance of solvent; and the dispersant is a high-molecular-weight polyurethane type dispersant or a high-molecular-weight polyacrylate type dispersant. The ink for ceramic ink-jet printing provided by the invention is good in quality stability and thereby can be stored for a long time; the ink is excellent in ink-jet printing performance, low in ink viscosity and even in particle size distribution; the viscosity of the ink is between 10.0 and 40.0 mPa.s and is controllable; and the surface tension of the ink is 28-38 mN/m, while the average particle size is 200-300 nm and the maximum particle size is less than 800 nm. The method for preparing the ink for ceramic ink-jet printing provided by the invention is simple and efficient; and a one-step mill base grinding process and an ink performance regulation process are carried out, so that the production cost is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of ceramic inkjet, and relates to an ink for ceramic inkjet printing and a preparation method thereof. Background technique [0002] Ceramic inkjet technology is a non-contact digital printing technology. It is ink made of ceramic pigment powder, and small ink droplets are sprayed from a nozzle with a diameter of tens of microns onto the surface of architectural ceramics. After firing The coloring decoration method, the shape and geometric size of the decorative pattern are controlled by the computer. Ceramic inkjet technology abandons the cumbersome traditional printing methods (such as screen printing and roller printing), and directly sprays printing on the green body, which improves the printing accuracy and realizes changeable pattern shapes. Therefore, the tiles produced The image is more realistic and closer to nature. [0003] Since the introduction of the first ceramic inkjet machine in my country...
