Method for preparing high-porosity h-BN-based ceramic material based on photocuring molding technology
The invention relates to the technical field of ceramic materials, and discloses a method for preparing a high-porosity h-BN-based ceramic material based on a photocuring molding technology, which comprises the following steps of: firstly, weighing HDDA, THFA, UDPA, PUA, n-octyl alcohol and ceramic raw materials according to the volume fraction, and mixing the raw materials to obtain ceramic slurry; secondly, placing the ceramic slurry on a 3D printer platform, forming a slurry film after the ceramic slurry passes through a scraper, and carrying out ultraviolet light curing treatment to obtaina single-layer ceramic green body; thirdly, repeating the step 2 to obtain a required ceramic green body; fourthly, taking down the ceramic green body and heating the ceramic green body for degreasing; and fifthly, carrying out air pressure sintering to obtain the high-porosity h-BN-based ceramic material. Ceramic green bodies with different raw material compositions and different shapes can be prepared by adopting photocuring and 3D printing forming technologies, the h-BN-based ceramic material with a complex shape and high porosity can be obtained through degreasing and sintering, and the high-porosity h-BN-based ceramic material with a complex shape can be prepared by utilizing a digital processing technology in a photocuring process.
