Preparation method of photo-cured aluminum oxide ceramic double-solvent slurry
The invention discloses a preparation method of photo-cured aluminum oxide (Al2O3) ceramic double-solvent slurry. The preparation method comprises the following steps: (1) carrying out weighing, namely respectively weighing hexanediol acrylate, polyurethane acrylate, three parts of spherical Al2O3 powder, a dispersing agent sodium polyacrylate, a photoinitiator and a tackifier according to a ratio; (2) preparing single-solvent slurry, namely preparing single-solvent slurry of hexanediol acrylate and Al2O3 and single-solvent slurry of polyurethane acrylate and Al2O3, adding a dispersing agent,adjusting the pH value to be alkaline, performing planetary ball-milling and stirring, and performing vacuum defoaming to obtain the single-solvent slurry; and (3) preparing double-solvent slurry, namely mixing and stirring the two kinds of single-solvent slurry, adding the rest Al2O3, the dispersing agent, the photoinitiator and the tackifier for multiple times, adjusting the pH value to be alkaline, performing planetary ball-milling and stirring, and defoaming in vacuum to obtain the double-solvent slurry. The Al2O3 ceramic slurry prepared by the method is high in dispersion uniformity, hasexcellent flowability and stability, ensures rapid forming of a photo-cured printing ceramic blank, and can be stored for a long time under a dark condition.
本发明公开了一种光固化氧化铝（Al2O3）陶瓷双溶剂浆料的制备方法：①称重：按照比例，分别称取己二醇丙烯酸酯、聚氨酯丙稀酸酯和三份的球形Al2O3粉、分散剂聚丙烯酸钠、光引发剂和增粘剂；②单溶剂浆料配制：配制己二醇丙烯酸酯与Al2O3、聚氨酯丙稀酸酯与Al2O3的单溶剂浆料，加入分散剂，调节pH值至碱性，行星球磨搅拌、真空除泡，得到单溶剂浆料；③双溶剂浆料配制：将2种单溶剂浆料混合搅拌，分多次加入余下的Al2O3、分散剂、光引发剂和增粘剂，调节pH值至碱性，行星球磨搅拌、真空除泡，得到双溶剂浆料。本发明制备的Al2O3陶瓷浆料分散均匀性高，具有优良的流动性和稳定性，保证了光固化打印陶瓷坯体的快速成型，同时在避光条件下可以长期保存。
