Aluminum oxide ceramic slurry for photocuring 3D printing, preparation method and aluminum oxide ceramic
The invention provides aluminum oxide ceramic slurry for photocuring 3D printing, a preparation method and aluminum oxide ceramic, and aims to effectively solve the technical defects that in the traditional aluminum oxide ceramic slurry preparation process, the solid phase content is low, the curing forming precision is poor, the product mechanical property is not high, and the like. The method comprises the following steps: 1, modifying aluminum oxide powder by adopting a polymeric dispersant containing an acidic group; and 2, mixing the modified aluminum oxide powder obtained in the step 1, a resin monomer composition, a photoinitiator and a diluent to obtain aluminum oxide ceramic slurry, wherein the resin monomer composition is composed of a monofunctional resin monomer, a bifunctional resin monomer and a resin monomer with three or more functional groups, and the mass ratio of the monofunctional resin monomer to the bifunctional resin monomer to the resin monomer with three or more functional groups is 1.8-3: 4-7: 0.5-3.2.
本发明提供一种光固化3D打印用氧化铝陶瓷浆料、制备方法及氧化铝陶瓷，能有效解决传统的氧化铝陶瓷浆料制备过程中固相含量低、固化成型精度差、产品力学性能不高等技术缺陷。该方法包括以下步骤：步骤1、采用含酸性基团的高分子型分散剂对氧化铝粉体进行改性；步骤2、将步骤1得到的改性的氧化铝粉体、树脂单体组合物、光引发剂和稀释剂混合处理即得氧化铝陶瓷浆料，其中，所述树脂单体组合物由单官能团树脂单体、双官能团树脂单体和三官能团以上树脂单体组成，且质量比为1.8～3:4～7:0.5～3.2。
