Sulfate-based composite binder for 3D printing ceramic material
The invention relates to a sulfate-based composite binder for a 3D printing ceramic material. The composite binder is composed of a component A and a component B, wherein the component A comprises a main component, a cosolvent and a diluent; and in percentage by weight, the main component of the component A is 45-84.9%, the cosolvent is 10-20%, the diluents is 5-20%, and the component B is 0.1-15%. The composite binder comprises a silicate or phosphate binder. The related technical problems of material updating, process improvement and the like in the prior art are solved. According to the preparation method of a composite binder of a 3D forming ceramic material, zirconia, alumina, silicon carbide, silicon nitride and other structural ceramic powders are quickly hardened and formed, the scheme simplifies the preparation process, the problems of long forming period, low workpiece precision, unstable mechanical properties, large size shrinkage and the like in the traditional process aresolved, and the non-molding production is realized.
本发明涉及一种3D打印陶瓷材料用硫酸盐基复合粘结剂。所述复合粘结剂由A、B组份组成；所述A组分包括主成分、助溶剂和稀释剂；按重量比计算A组分的主成分45～84.9％、助溶剂10～20％、稀释剂5～20％以及B组分0.1～15％；所述复合粘结剂包括硅酸盐或磷酸盐系粘结剂。本发明克服了现有技术针对材料更新和工艺改进等相关技术问题，本发明提供了一种3D成型陶瓷材料的复合粘结剂制备方法，能够将氧化锆、氧化铝、碳化硅、氮化硅等结构陶瓷粉末快速硬化成型，本发明方案简化了制备流程，解决了传统工艺存在的成型周期长、制件精度低、力学性能不稳定和尺寸收缩大等问题，实现了无模化生产。
