Nano ceramic slurry for photocuring forming and preparation method thereof
The invention relates to the technical field of ceramic slurry, in particular to nano ceramic slurry for photocuring forming and a preparation method of the nano ceramic slurry. The invention provides the nano ceramic slurry with high solid content and low viscosity, the ceramic slurry comprises 35-90 wt% of ceramic powder, 10-65 wt% of photosensitive resin, a dispersant accounting for 2-5% of the mass of the ceramic powder and a sintering aid accounting for 1-5% of the mass of the photosensitive resin, and the solid content of the prepared ceramic slurry reaches up to 60.21 vol% through a mode of combining mechanical mixing and ball milling. The viscosity is as low as 24778 mPa.s, the low viscosity is beneficial to flattening of the slurry in the printing process, the final printing quality is improved, the high solid content can reduce the cracking problem of a ceramic blank in the subsequent degreasing and sintering link, and the ceramic density is improved.
本发明涉及陶瓷浆料技术领域，更具体的说是一种用于光固化成型的纳米陶瓷浆料及其制备方法。提供一种高固含量且粘度低的纳米陶瓷浆料，该陶瓷浆料包括35wt％‑90wt％陶瓷粉末、10wt％‑65wt％光敏树脂、陶瓷粉末质量2％‑5％的分散剂和光敏树脂质量1％‑5％的烧结助剂，通过机械混合与球磨结合的方式，制备出的陶瓷浆料固含量高达60.21vol％，粘度低至24778mPa.s，低粘度有利于浆料在打印过程中的铺平，提高最终打印质量，高固含量可以减少陶瓷胚体在后续的脱脂烧结环节中的开裂问题，提高陶瓷致密度。
