Preparation method and application of ceramic slurry with high photocuring performance
The invention discloses a preparation method and application of ceramic slurry with high photocuring performance, and the preparation method of the ceramic slurry with high photocuring performance comprises the following steps: firstly, mixing nano powder with an auxiliary agent A, dispersing the nano powder through pretreatment, then forming micron-sized spherical nano agglomerated powder particles through spray granulation, and drying the micron-sized spherical nano agglomerated powder particles to obtain the ceramic slurry with high photocuring performance. The preparation method comprises the following steps: preparing nano powder particles, calcining to further improve the binding force among the nano powder particles, forming coated powder by utilizing a hot fluid water bath coating mode, mixing and dispersing the coated powder and an auxiliary B to obtain the high-light curing performance ceramic slurry, and reducing the refractive index of the powder by utilizing an organic polymer coating agent film layer in the core-shell structure powder contained in the slurry, so that the high-light curing performance ceramic slurry is obtained. Therefore, the slurry which can be directly applied to photocuring 3D printing can be prepared from the ceramic material with high refractive index and high absorbance, the vacancy of the material in photocuring 3D printing can be filled, and the range of materials used for photocuring printing can be expanded.
