Silicon-based ceramic slurry for photocuring 3D printing and preparation method of silicon-based ceramic slurry
The invention relates to silicon-based ceramic slurry for photocuring 3D printing and a preparation method thereof, and the silicon-based ceramic slurry comprises the following components by mass: 65%-80% of modified ceramic powder, 15%-30% of acrylic photosensitive resin, 1%-4% of a photoinitiator and 1%-4% of other auxiliary agents; the modified ceramic powder is prepared from the following components in percentage by mass: 67 to 89 percent of silicon oxide powder, 10 to 30 percent of zirconium silicate powder and 1 to 3 percent of dispersing agent. The method comprises the following steps: adding a dispersing agent into absolute ethyl alcohol, and uniformly stirring to prepare a solution; adding silicon oxide and zirconium silicate ceramic powder into the solution, and carrying out ball milling to obtain a slurry mixture; drying the mixture, and sieving to obtain modified ceramic powder; and adding acrylic photosensitive resin, a photoinitiator, other auxiliaries and the like into the ceramic powder, and homogenizing to obtain the silicon oxide ceramic printing slurry. The method disclosed by the invention is suitable for preparing the silicon-based ceramic slurry for photocuring 3D printing, which is high in solid content, high in stability, small in sintering deformation and good in physical property.
