Alumina slurry suitable for photocuring 3D printing and preparation method thereof
The invention discloses an aluminum oxide slurry suitable for photocuring 3D printing, and belongs to the field of additive manufacturing, the aluminum oxide slurry comprises the following components by mass: 57 wt%-82 wt% of modified gamma-Al2O3, 15 wt%-42 wt% of photosensitive resin, 0.2 wt%-0.8 wt% of a coloring agent, and 0.3 wt%-0.9 wt% of a dispersant. Wherein the modified gamma-Al2O3 is obtained by modifying gamma-Al2O3 through a surface active agent. The modified gamma-Al2O3, the resin and other related auxiliaries are matched to obtain the aluminum oxide ceramic slurry which is high in solid content, low in viscosity and good in rheological property, the preparation method of the aluminum oxide ceramic slurry is provided, and the problem of cracking of aluminum oxide ceramic in the subsequent degreasing and sintering process is solved.
本发明公开一种适用于光固化3D打印的氧化铝浆料，属于增材制造领域，所述氧化铝浆料包括后述质量份数的成分，改性γ‑Al2O3：57wt％‑82wt％，光敏树脂：15wt％‑42wt％，染色剂：0.2wt％‑0.8wt％，分散剂：0.3wt％‑0.9wt％。其中，改性γ‑Al2O3由γ‑Al2O3经表面活性剂改性获得。本发明采用改性γ‑Al2O3、树脂和其他相关助剂配伍得到了一种高固含量、粘度低且流变性好的氧化铝陶瓷浆料，并提供了其制备方法，解决了后续脱脂烧结过程中氧化铝陶瓷的开裂问题。
