Embodiment 1

[0047] 1. Drug and reagent preparation

[0048] Raw material preparation for solution preparation: zirconium oxychloride octahydrate, analytically pure, content ≥99.0%, Shanghai Runjie Chemical Reagent Co., Ltd.; ethylene glycol methyl ether, analytically pure, content ≥99.0%, Tianjin Fuyu Fine Chemical Co., Ltd. ; polyvinylpyrrolidone (PVP) K30, Shanghai Boao Biotechnology Co., Ltd.; ethylene glycol, analytically pure, content ≥ 99.0%, Shanghai Runjie Chemical Reagent Co., Ltd.

[0049] 2. Substrate and container cleaning

[0050] Finger bottle cleaning: unscrew the bottle cap of the finger bottle to be washed, sink it into a large beaker filled with isopropanol, and put the bottle cap together. It should be noted that the bottle must be completely filled with isopropanol, and no Bubbles, then ultrasonic (53kHz) vibration for 15min, then deionized water and the same ultrasonic (53kHz) vibration for 15min. Care should be taken to avoid contacting the inner wall of the bottle...

Abstract

The invention discloses an ink for inkjet printing and a preparation method as well as a zirconia film printed by the ink for the inkjet printing. The preparation method for the ink for the inkjet printing comprises the steps: (1) dissolving zirconium oxychloride in a mixed solvent to obtain a mixed solution, wherein the mixed solvent is prepared from ethylene glycol monomethyl ether and ethylene glycol in a volume ratio of (0.5 to 2) to (2 to 1)1; (2) adding PVP to the mixed solution obtained in the step (1), dissolving and standing to aging, and obtaining the ink for the inkjet printing. According to the ink for inkjet printing and the preparation method as well as the zirconia film printed by the ink for the inkjet printing, the polymer PVP is introduced in the process of preparing the ink for the inkjet printing, the viscosity and the dispersion of the solution are adjusted by due to the existence of the polymer, the system is more likely to generate gelatinization, and the flow of the liquid phase is restricted and the coffee-ring effect is weakened, so that the flatness of the surface of the zirconia film printed by the ink is improved.

Description

technical field [0001] The invention belongs to the field of flat panel display, and in particular relates to an ink for inkjet printing, a preparation method and a zirconia film printed by the same. Background technique [0002] The existing ways of preparing metal oxide thin films by inkjet printing mainly include sol-gel method (Sol-Gel) and nanoparticle blending method. The nanoparticle blending method is to uniformly disperse nanoscale particles of metal oxides in a solvent, apply the solution on the surface of the substrate, heat to remove the solvent and calcinate at a high temperature to prepare an oxide film; the Sol-Gel method is through solvation And hydrolysis reaction, the metal salt is dissolved in the solvent to form a stable sol, the solvent is removed by heating, the sols are polymerized to form a three-dimensional network gel structure, and finally the molecular and even nano-substructure materials are solidified by drying and sintering . Since the Sol-Ge...
