Method for preparing porous quartz ceramic through photo-curing molding
The invention discloses a method for preparing porous quartz ceramic through photo-curing molding, which comprises the following steps: by using fused nano quartz powder as a raw material, epoxy acrylate as photocuring resin, polyethylene glycol 400 as a dispersing agent, solid phase with content of 20-45 wt% and 0.5-1.2 wt% of a dispersing agent, carrying out planetary ball milling and vacuum defoaming to prepare photocuring molding slurry; preparing a porous ceramic biscuit by adopting a photocuring 3D forming technology; after the biscuit is cleaned and dried, grease discharging is conducted at the temperature of 400-600 DEG C, then performing calcination at the temperature of 1300-1500 DEG C, and obtaining the porous quartz ceramic. The porous quartz ceramic prepared by the photocuring3D forming technology is uniform in pore structure size, uniform in distribution and controllable in density.
本发明公开了一种光固化成型制备多孔石英陶瓷的方法，具体内容为：熔融纳米石英粉为原料，环氧丙烯酸酯为光固化树脂，聚乙二醇400为分散剂，固相含量20‑45 wt%，分散剂0.5‑1.2 wt%，通过行星球磨、真空除泡，配置光固化成型浆料；采用光固化3D成型技术，制备多孔陶瓷素坯；素坯清洗、烘干后，先进行400‑600℃排脂，再进行1300‑1500℃煅烧，得到多孔石英陶瓷。本发明运用光固化3D成型技术制备的多孔石英陶瓷，其孔结构大小均一、分布均匀，且密度可控。
