| titleOfInvention | Preparation method of zirconium silicate coated iron oxide red for ceramic ink-jet printing |
| abstract | The invention discloses a preparation method of a zirconium silicate coated iron oxide pigment for ceramic ink-jet printing. Firstly, slowly dropping a weak alkaline solution into an iron salt solution to form an iron hydroxide sol, heating to form an iron oxide nano core, adding a zirconium oxychloride solution, then dropping a sulfate solution with a molar ratio of 1-4 times, separating out the zirconium sulfate solution on the surface of the iron oxide nano core by utilizing the characteristic of low solubility of the zirconium sulfate to form a compact coating layer, then dropping a carbonate solution to slowly convert the zirconium sulfate coating layer into a zirconium carbonate coating layer, finally adding water glass to form a silicon hydroxide coating layer, and drying and calcining to obtain the zirconium iron red pigment for ceramic ink-jet printing; the dispersant is added to further reduce the granularity of the pigment, and the metal ions are added to improve the bright red degree of the pigment. The invention enables the iron oxide particles to be wrapped in a nano state, the wrapping process is compact and sufficient, the activity of the synthesized semi-finished product is extremely high, the calcining temperature is lower than 800 ℃, the granularity of the obtained pigment is less than 1 micron, the color is bright red, and the requirements of ceramic ink-jet printing are completely met. |
