Preparation method of photocuring 3D printing silicon carbide porous ceramic membrane
The invention discloses a preparation method of a photocuring 3D printing silicon carbide porous ceramic membrane, which comprises the following steps: preparing silicon carbide slurry by using silicon carbide powder and photosensitive resin as raw materials, obtaining a ceramic membrane green body by using a photocuring 3D printing forming process, and then obtaining the silicon carbide porous ceramic membrane through a glue discharging-sintering process. By regulating and controlling the components of the photosensitive resin and the silicon carbide powder in the slurry, the slurry shows relatively high curing depth and relatively low curing width, and a high-precision ceramic membrane green body is successfully prepared; meanwhile, by changing the solid content of the slurry and the particle size of silicon carbide particles, the pore structure of the silicon carbide porous ceramic membrane is regulated and controlled, and the prepared ceramic membrane is uniform in pore structure. The silicon carbide porous ceramic membrane is prepared through photocuring 3D printing, the problems that silicon carbide slurry is difficult to photocure, low in precision and the like are solved, the preparation process is simple, the forming rate is high, and an effective way is provided for preparing the silicon carbide porous ceramic membrane in a complex shape.
本发明公开了一种光固化3D打印碳化硅多孔陶瓷膜的制备方法，以碳化硅粉体和光敏树脂为原料制备碳化硅浆料，采用光固化3D打印成型工艺得到陶瓷膜生坯，再经过排胶‑烧结过程得到碳化硅多孔陶瓷膜。通过对浆料中光敏树脂和碳化硅粉体的组分调控，使浆料表现出较高的固化深度和较低的固化宽度，成功制备出高精度的陶瓷膜生坯；同时，通过改变浆料固含量和碳化硅颗粒粒径，实现碳化硅多孔陶瓷膜孔结构调控，制备的陶瓷膜孔结构均匀。本发明采用光固化3D打印制备碳化硅多孔陶瓷膜，解决了碳化硅浆料光固化困难、精度低等问题，制备过程简单，成型率高，为制备复杂形状的碳化硅陶瓷膜提供了有效途径。
