Preparation method of zirconium oxide photocuring ceramic slurry
The invention belongs to the technical field of materials, and provides a preparation method of zirconium oxide photocuring ceramic slurry, which comprises the following steps: preparing a liquid phase in advance, mixing a solid phase and the liquid phase, and optimizing the particle size ratio of ceramic particles to improve the rheological property and stability of the slurry. The preparation process comprises the following steps: mixing zirconium oxide powder with the average particle size of 1 mu m and 0.1 mu m according to the optimized proportion and the mass ratio of 3: 1 to prepare a solid phase for later use, uniformly mixing a resin monomer and a photoinitiator in a constant-temperature environment through magnetic stirring to prepare a liquid phase, carrying out ball-milling mixing on the solid phase, the liquid phase and a dispersing agent according to the solid phase content of 60wt%, and carrying out drying to obtain the zirconium oxide resin. The zirconium oxide light-cured ceramic slurry with relatively good rheological property and stability is obtained. According to the method disclosed by the invention, binary particle size matching is optimized, so that relatively good rheological property and stability of the zirconium oxide ceramic slurry are realized, meanwhile, the curing property of the zirconium oxide ceramic slurry is not influenced, and the requirements of photocuring 3D printing ceramic parts can be better met.
