High-precision photocuring 3D printing ceramic slurry and preparation method thereof
The invention discloses high-precision photocuring 3D printing ceramic slurry and a preparation method thereof.The high-precision photocuring 3D printing ceramic slurry comprises ceramic powder, ethyl alcohol, epoxy resin and a curing agent, the volume of the ceramic powder is equal to that of the ethyl alcohol, the volume of the epoxy resin is 1/40-1/20 of that of the ethyl alcohol, and the proportion of the curing agent to the epoxy resin is 1: 1. S2, stirring in a water bath; s3, performing heat preservation in a drying oven; s4, crushing by a grinding machine; s5, performing heat preservation in a vacuum oven; s6, fully and mechanically stirring the powder obtained in the step S5, a UV monomer and a photoinitiator; s7, putting the slurry into a horizontal ball mill for low-speed ball milling; and S8, carrying out defoaming treatment on the slurry. The invention relates to the technical field of photocuring 3D printing materials. According to the high-precision photocuring 3D printing ceramic slurry and the preparation method, the curing precision of the slurry is improved, the strength of a ceramic green body is improved, heavy metal and alkali metal elements are not introduced, and high solid content can be achieved without additionally adding a dispersing agent or a wetting agent.
本发明公开了一种高精度光固化3D打印陶瓷浆料及制备方法，包括陶瓷粉体、乙醇、环氧树脂和固化剂，其中陶瓷粉体与乙醇的体积相等，环氧树脂为乙醇体积的1/40‑1/20，且固化剂与环氧树脂比例为1：1，其制备方法为：S1、混合；S2、水浴搅拌；S3、置于烘箱中保温；S4、研磨机打碎；S5、置入真空烘箱保温；S6、将步骤S5得到的粉体与UV单体、光引发剂充分机械搅拌；S7、将浆料置入卧式球磨机进行慢速球磨；S8、将浆料进行脱泡处理，本发明涉及光固化3D打印材料技术领域。该高精度光固化3D打印陶瓷浆料及制备方法，提高浆料的固化精度，提高陶瓷生坯的强度，不引入重金属及碱金属元素，并且不用额外添加分散剂或润湿剂就能实现较高固含量。
