Problems solved by technology

However, this solution has exposed many problems when applied to inkjet printing
First of all, the ink used for printing must be a slow-drying solution, and the solvent ethylene glycol methyl ether of the above solution has a low boiling point and vapor pressure, and the ink droplets are often solidified before they can fuse into a whole pattern during printing. ;In addition, the overall viscosity of the solution is low due to the low viscosity of the solvent, and its inkjet state and pattern forming effect are not good when applied to printing

Abstract

The invention discloses an ink-jet printing ink for a zirconia insulating layer and a preparation method thereof. The ink comprises a solute and a solvent. The solute is zirconium oxychloride. The solvent is ethylene glycol methyl ether, glycol, and polyethylene glycol. The ink is prepared by dissolving zirconium oxychloride into the mixed solvent of ethylene glycol methyl ether, glycol, and polyethylene glycol, evenly stirring the solution, and aging the solution. Glycol and polyethylene glycol are introduced into the ink, the boiling point and viscosity of the solution is increased, at the same time, the dissolution of zirconium oxychloride is not influenced, and the prepared system is stable and is more suitable for ink-jet printing.

Description

technical field [0001] The invention belongs to the field of flat panel display, in particular to an ink for inkjet printing zirconia insulating layer and a preparation method thereof. Background technique [0002] Existing solution methods for processing insulating layers mainly include spin coating, inkjet printing, and roll-to-roll. Among them, the spin coating process has been widely used in scientific research because of its simple process and excellent film quality. A solution commonly used in the spin coating process is to dissolve zirconium oxychloride in ethylene glycol methyl ether to form a metal hydroxide as a precursor, use the solution to spin coat and heat to remove the solvent, and at the same time the metal hydroxide is polymerized and oxidized. A metal-oxygen-metal structure is formed, and finally a zirconia film is formed. The above solutions have been successfully applied in the spin-coating process and have been reported in many literatures. However, ...
