Preparation method of barium titanate-based ceramic slurry for photocuring 3D printing
The invention discloses a preparation method of BaTiO3-based ceramic slurry for photocuring 3D printing. The ceramic slurry is prepared from the following raw and auxiliary materials in percentage: 30 to 77 weight percent of BaTiO3 powder, 15 to 45 weight percent of photosensitive resin, 1.5 to 5 weight percent of a photoinitiator, 1.2 to 7.5 weight percent of an anti-settling agent and 0.8 to 8.5 weight percent of a hydroxyl dispersing agent. The obtained BaTiO3-based ceramic slurry has the advantages of being high in solid loading capacity, small in powder particle size, low in viscosity, high in fluidity and low in settling velocity, the preparation mode is simple, 3D printing of products of complex and precise structures can be met, the requirement for direct forming of 3D printing is met, and meanwhile the variety of 3D printing materials is expanded.
本发明公开了一种光固化3D打印用BaTiO3基陶瓷浆料的制备方法，该陶瓷浆料由以下质量分数的原辅料制备而成：BaTiO3粉体30wt％～77wt％、光敏树脂15wt％～45wt％、光引发剂1.5wt％～5wt％、防沉剂1.2wt％～7.5wt％、羟基分散剂0.8wt％～8.5wt％。本发明所得BaTiO3基陶瓷浆料具有固体负载量高、粉体粒径小、粘度低、流动性好和沉降速度慢的优点，并且制备方式简单，能够满足复杂精密结构产品的3D打印，符合3D打印直接成型的需求，同时拓展了3D打印材料的种类。
