Zirconia ceramic powder for photocuring 3D printing and preparation method thereof
The invention discloses zirconium oxide ceramic powder for photocuring 3D printing, which is prepared from the following components in parts by weight: 10 to 300 parts of zirconium oxide, 0.5 to 10 parts of silane coupling agent, 80 to 100 parts of absolute ethyl alcohol, 5 to 20 parts of deionized water, 0.01 to 0.1 part of photoinitiator and 1 to 5 parts of photosensitive resin. The zirconium oxide is dried zirconium oxide powder. The silane coupling agent is a silane coupling agent with a C = C double bond. According to the invention, a two-step modification method is adopted to carry out surface modification treatment on zirconium oxide powder, i.e., the surface of the zirconium oxide powder is pre-modified through a silane coupling agent, so that the hydrophilic and oleophylic characteristics of the zirconium oxide powder are changed; then, the dispersion stability of the zirconium oxide powder in the photosensitive resin is further improved through secondary modification of the photosensitive resin, and the zirconium oxide powder subjected to secondary modification has the characteristics of reducing viscosity and improving the storage stability of the slurry. The invention also provides a preparation method of the zirconia ceramic powder for photocuring 3D printing.
本发明公开了一种光固化3D打印用氧化锆陶瓷粉体，按重量份数，包括以下组分：氧化锆10‑300份，硅烷偶联剂0.5‑10份，无水乙醇80‑100份，去离子水5‑20份，光引发剂0.01‑0.1份，光敏树脂1‑5份。所述氧化锆为干燥后的氧化锆粉末。所述硅烷偶联剂为带有C＝C双键的硅烷偶联剂。本发明采用两步改性法对氧化锆粉体进行表面改性处理，即先通过硅烷偶联剂对氧化锆粉体表面进行预改性，从而改变氧化锆粉体的亲水亲油特性；之后，通过光敏树脂的二次改性来进一步的提高氧化锆粉体在光敏树脂中的分散稳定性，二次改性后的氧化锆粉体具有降粘和提升浆料储存稳定性的特点。本发明还提供了上述光固化3D打印用氧化锆陶瓷粉体的制备方法。
