Cerium oxide ceramic slurry suitable for photocuring 3D printing, and preparation and forming method thereof
The invention discloses cerium oxide ceramic slurry suitable for photocuring 3D printing and a preparation and forming method, the cerium oxide ceramic slurry comprises surface-modified cerium oxide ceramic powder, a low-absorbance powder filler, a slurry liquid phase and a photoinitiator, and the surface-modified cerium oxide ceramic powder is cerium oxide ceramic powder with a dispersing agent attached to the surface; wherein the total mass of the cerium oxide ceramic powder and the low-absorbance powder filler accounts for 40-50% of the volume of the cerium oxide ceramic slurry, and the ratio of the volume of the cerium oxide ceramic powder to the volume of the low-absorbance powder filler is (1-4): 1; the volume of the slurry liquid phase accounts for 50-60% of the volume of the cerium oxide ceramic slurry; the mass of the dispersing agent accounts for 1-3% of that of the cerium oxide ceramic powder; the mass of the photoinitiator accounts for 1%-3% of the mass of the slurry liquid phase; the slurry liquid phase comprises the following components in percentage by mass: 40%-50% of 4-acryloylmorpholine serving as a photosensitive monomer, 10%-20% of ethyoxyl pentaerythritol tetraacrylate serving as a cross-linking agent and 30%-40% of polypropylene glycol-400 serving as a diluent. According to the method, photocuring 3D printing forming of the cerium oxide ceramic sample piece and preparation of a complex porous structure can be achieved.
