Problems solved by technology

The use of nano-color enhancers achieves stable color development of the ink and increases the color strength. However, most of the red bleed inks prepared using organometallic iron salts have a brownish and darker color, and it is still difficult to achieve bright red. Reach, thereby reducing the decorative effect of ceramic products, and restricting the application of bleeding ink

Abstract

The invention discloses a bright red ceramic ink-jet bleeding ink and a preparation method thereof. The bleeding ink is composed of an organic metal salt and a solvent. The organic metal salt is a mixed salt of iron, calcium and sodium. The content is 5-6%, the content of zirconium is 1-3%, and the content of sodium is 0-2.5%. The organic metal salt is soluble in solvent and can be converted into bright red metal oxide at high temperature. The ink of the invention solves the problem that the red color of the bleed ink is dark and not bright enough, has a bright red color, enriches the color gamut of the bleed ink, and can greatly improve the decorative effect of the inkjet polished tile.

Description

technical field [0001] The invention relates to the technical field of ceramic inkjet printing, in particular to a bright red ceramic inkjet bleeding ink and a preparation method thereof. Background technique [0002] The ceramic ink prepared by dissolving soluble metal salts in organic solvents is called ceramic bleed ink. Because the preparation method is simple, and the coloring metal is stored in the ink in the form of ions, it will not block the nozzle. Therefore, bleed ink started in 2015 Appeared in 2010, it has been popularized and applied very quickly. The color bodies used in bleeding ink are metal ions. These metal ions are easy to chemically react with the relevant components in the polished tile fabric. It is difficult to emit bright colors at high temperatures, which is a technical difficulty in the application of bleeding ink. At present, the colors used in the production line are mainly red (Fe), blue (Co), yellow (Ti and Cr), black (Fe and Co). Among the a...
