Preparation method of spodumene glass ceramic printing slurry for near-net forming
The invention discloses a preparation method of spodumene glass ceramic printing slurry for near-net shaping. Hydroxyethyl cellulose is used as a dispersing agent, water is used as a solvent to prepare the (spodumene) LAS slurry, and the prepared slurry can meet the forming requirement of direct-writing 3D printing. The method mainly comprises the following steps: adding a dispersing agent into a (spodumene) LAS solution at room temperature, and obtaining printable paste with low paste viscosity and good dispersity within a certain adding amount range. The method belongs to the field of additive manufacturing, the stable printable 3D printing slurry can be prepared through the method, and the method has important application prospects in the aspect of near-net-shape 3D printing of spodumene ceramics.
本发明公开了一种用于近净成型的锂辉石玻璃陶瓷打印料浆的制备方法。利用羟乙基纤维素作为分散剂，水为溶剂制备（锂辉石）LAS浆料，制备的浆料可以满足直写3D打印的成型要求。主要包括以下步骤：室温下，在（锂辉石）LAS溶液中加入分散剂，在一定添加量范围内，可以得到的浆料粘度低分散性好的可印刷浆料。本发明属于增材制造领域，该方法能制备出稳定可印刷的3D打印浆料，在近净成型3D打印锂辉石陶瓷方面具有重要的应用前景。
