Preparation method of 3D ceramic printing raw material
The invention provides a preparation method of a 3D ceramic printing raw material. The preparation method comprises the following steps: uniformly grinding raw loess in a mortar, calcining in a high-temperature furnace, cooling, carrying out ball milling, and sieving with a 90-mesh sieve to obtain cooked loess; mixing the mineral powder, the raw loess, the cooked loess and the feldspar powder, adding sodium tripolyphosphate and sodium carboxymethyl cellulose, uniformly mixing, and finely grinding to 280 meshes; adding aluminum oxide micro powder and titanium dioxide micro powder, modifying and finely grinding to 280 meshes; adding hydrogel for optimization; and adding the hydrogel to obtain the 3D ceramic printing raw material. According to the invention, the mineral powder rich in various metal elements is utilized, formula modulation and optimization are carried out on the basis of traditional ceramic raw materials, and the hardness of the raw materials is enhanced by utilizing the characteristics of metal ions; on the basis, a certain amount of hydrosol is added according to the characteristic of fast discharging of a third-generation lute card coordinate type 3D ceramic printer so that the discharging stability is improved, and the produced ceramic is not easy to crack. The problems of difficult grain forming and low reduction degree caused by insufficient precision, strength and viscosity are effectively solved.
一种3D陶瓷打印原料的制备方法，将生黄土在研钵中研磨均匀，置于高温炉中煅烧，待冷却后球磨，过90目筛得熟黄土；将矿石粉、生黄土、熟黄土和长石粉混合，再加入三聚磷酸钠和羧甲基纤维素钠混合均匀，细磨至280目；加入铝氧化物微粉和二氧化钛微粉进行改性细磨至280目；加入水凝胶进行优化：加入水凝胶得到3D陶瓷打印原料。本发明利用富含多种金属元素的矿石粉，在传统陶瓷原料的基础上进行配方调制和优化，利用金属离子的特性增强原料的硬度；在此基础上，针对第三代笛尔卡坐标式3D陶瓷打印机出料快的特点，加入了一定量的水溶胶，不但提高了出料的稳定性，而且也使得生产出的陶瓷不易开裂。有效解决了因精度、强度、粘粘度不足导致的成纹难、还原度低的问题。
