The invention discloses a zirconia ceramic slurry, a preparation method thereof, a denture and a preparation method for the denture. The raw materials of the zirconia ceramic slurry include yttria-stabilized zirconia, a dispersant, an ultraviolet absorber, a photoinitiator, a photosensitive resin, a toughening agent, a binding aid, a defoaming agent and a silane coupling agent; the yttria-stabilized zirconia The weight parts of zirconia are 60 parts to 75 parts, the weight parts of dispersants are 2 parts to 4 parts, the weight parts of ultraviolet absorbers are 1 part to 3 parts, and the weight parts of photoinitiators are 3 parts to 5.2 parts, The weight part of the photosensitive resin is 18-26 parts, the weight part of the toughening agent is 3-6 parts, the weight part of the coagulant is 5-11.4 parts, and the weight part of the defoamer is 2-2.6 parts , the weight part of the silane coupling agent is 1 to 3 parts; the particle size of the yttria-stabilized zirconia is 50 nm to 100 nm. The slurry can effectively solve the defect that the traditional zirconia slurry is easy to settle for a long time. |
