3D printing ceramic slurry and preparation method thereof
The invention is suitable for the technical field of materials, and provides 3D printing ceramic slurry and a preparation method thereof. The method comprises the following steps: performing ball milling and drying pretreatment on silicon dioxide ceramic powder by adopting a coupling agent to obtain pretreated silicon dioxide ceramic powder; and putting resin, a dispersing agent, a photoinitiatorand an ultraviolet stabilizer into a reaction container, carrying out ball milling until all the components are completely dissolved, adding a ceramic pigment and the pretreated silicon dioxide ceramic powder, and carrying out ball milling to obtain the 3D printing ceramic slurry. The silicon dioxide ceramic powder is subjected to ball milling and drying pretreatment by adopting the coupling agent, so that the binding degree with resin can be improved, and the problem of poor binding property between the silicon dioxide ceramic powder and the resin is solved. The ceramic pigment is introducedand subjected to ball milling, so that the ceramic pigment is uniformly distributed in the slurry, a ceramic finished product printed by the ceramic slurry is colored, the color distribution is uniform, and the color forming quality is good. The risk of degreasing and cracking of a green body is reduced by adding the ultraviolet stabilizer.
本发明适用于材料技术领域，提供了一种3D打印陶瓷浆料及其制备方法，该方法包括：采用偶联剂对二氧化硅陶瓷粉体进行球磨、烘干预处理得到预处理后的二氧化硅陶瓷粉体；将树脂、分散剂、光引发剂、紫外稳定剂投入反应容器中进行球磨至各组分完全溶解，再加入陶瓷颜料和预处理后的二氧化硅陶瓷粉体，并球磨得到3D打印陶瓷浆料。通过采用偶联剂对二氧化硅陶瓷粉体进行球磨、烘干预处理，可提高与树脂的结合度，解决了二氧化硅陶瓷粉体与树脂结合性差的问题；且通过引入陶瓷颜料，并进行球磨使得陶瓷颜料均匀分布在浆料中，该陶瓷浆料打印出来的陶瓷成品即有颜色，且颜色分布均匀、成色质量好，且通过添加紫外稳定剂，降低了生坯脱脂开裂的风险。
