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 bright red ceramic inkjet color-penetrating ink and a preparation method thereof. The bright red ceramic inkjet color-penetrating ink is composed of an organic metal salt and asolvent. The organic metal salt is a mixed salt of 5 to 6% of iron, 1 to 3% of zirconium and 0 to 2.5% of sodium, and the organic metal salt is dissolved in the solvent and can be converted into a bright red metal oxide at high temperature. The bright red ceramic inkjet color-penetrating ink solves the problems that the red color of the color-penetrating ink is dark and not bright enough. The bright red ceramic inkjet color-penetrating ink has bright red color, enriches the color gamut of the color-penetrating ink, and can greatly improve the decorative effect of inkjet polishing bricks.
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 promoted 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 abov...
