High-toughness 3D printing ceramic powder slurry
The invention discloses high-toughness 3D printing ceramic powder slurry which comprises main materials and auxiliary materials, and the mass ratio of the main materials to the auxiliary materials is10-15: 1.5-2; the main material formula of the high-toughness 3D printing ceramic powder slurry comprises the following components in parts by mass: 200-400 parts of 3Y zirconium oxide, 400-600 partsof whisker silicon, 200-600 parts of spodumene, 150-450 parts of andalusite and 100-150 parts of neutral alumina sol; the auxiliary material formula of the high-toughness 3D printing ceramic powder slurry comprises the following components in parts by mass: 1-5 parts of a thixotropic agent, 8-12 parts of a dispersing agent, 15-35 parts of a thickener, 1-10 parts of a leveling agent and 200-450 parts of water. Compared with existing ceramic powder slurry, the high-toughness 3D printing ceramic powder slurry has the advantages that the 3Y zirconium oxide, spodumene and andalusite are added intothe formula of the 3D printing ceramic powder slurry, and the 3Y zirconium oxide, spodumene and andalusite are compounded with whisker silicon, so that performance parameters of the powder material can be greatly improved, the fracture toughness and bending strength of the powder material are improved, and the thermal shock resistance and toughness of the powder material are improved.
本发明公开了一种高韧性3D打印陶瓷粉体浆料，包括主料和辅料，所述主料与辅料之间的质量比为：主料∶辅料＝10‑15∶1.5‑2；按质量份数计，该高韧性3D打印陶瓷粉体浆料的主料配方包括：3Y氧化锆200‑400份、晶须硅400‑600份、锂辉石200‑600份、红柱石150‑450份、中性铝溶胶100‑150份；按质量份数计，该高韧性3D打印陶瓷粉体浆料的辅料配方包括：触变剂1‑5份、分散剂8‑12份、增稠剂15‑35份、流平剂1‑10份、水200‑450份。本发明通过在3D打印陶瓷粉体浆料的配方中添加3Y氧化锆、锂辉石和红柱石在与现有的陶瓷粉体浆料相比，通过3Y氧化锆、锂辉石和红柱石与晶须硅复合可以极大地提高粉末材料的性能参数，提高其断裂韧性、抗弯强度，提高其抗热振性以及韧性。
