Photocuring 3D printing silicon-based ceramic core and preparation method thereof
The invention relates to a photocuring 3D printing silicon-based ceramic core and a preparation method thereof, and relates to the field of additive manufacturing ceramic materials. According to the main technical scheme, the preparation method of the photocuring 3D printing silicon-based ceramic core comprises the following steps: 1) preparing photocuring 3D printing ceramic core slurry; wherein the light-cured 3D printing ceramic core slurry is prepared from the following components in parts by weight: 30 to 50 parts of silicon dioxide skeleton powder, 20 to 50 parts of filler, 10 to 15 parts of through hole agent and 15 to 30 parts of light-cured resin premixed liquid, the through hole agent is formed by coating organic fibers with organic siloxane; 2) performing photocuring 3D printing treatment on the photocuring 3D printing ceramic slurry through photocuring 3D printing equipment to obtain a silicon-based ceramic core biscuit; and 3) degreasing and sintering the silicon-based ceramic core biscuit to obtain the photocuring 3D printing silicon-based ceramic core. The method is mainly used for improving the open porosity of the silicon-based ceramic core on the basis of ensuring that the silicon-based ceramic core has relatively high strength.
