摘要: 围绕陶瓷粉体在光敏树脂中的分散,研究了粉体性质、分散剂种类及其掺加量、固含量对光固化ZrO2陶瓷料浆流变性能的影响。结果表明:粉体性质对料浆的流变性能有着显著影响,比表面积小、球形度高的ZrO2陶瓷粉体更有利于配制低粘度、高固含量的料浆;料浆的流变性能以及稳定性主要受分散剂种类及其掺加量的控制,以相对粉体质量4%的X-100分散剂制备的陶瓷料浆的流变性及稳定性更佳;固含量与粘度之间的关系满足Krieger-Dougherty模型。本文对分散剂的作用机理进行了分析探讨,为光固化ZrO2陶瓷料浆高精度固化成型提供了试验基础。

Abstract: This paper focuses on the dispersion of ceramic powder in photosensitive resin. The effects of powder properties, dispersant type and dosage, and solid content on the rheological properties of stereolithography ZrO2 ceramic slurry were studied. The result shows that the properties of the powder have a significant impact on the rheological properties of the slurry, the use of ZrO2 powder with a smaller specific surface area and higher sphericity is more conducive to the preparation of low viscosity and high solid content slurry. The rheological properties and stability of the slurry are mainly controlled by the type and dosage of dispersant, using X-100 with a relative powder mass of 4% as a dispersant, the rheological properties and stability of the prepared ceramic slurry are better. The experimental result of the solid content of the slurry shows that the relationship between the solid content of the slurry and the viscosity satisfies the Krieger-Dougherty model. And the dispersion mechanism of the dispersant has been studied. By the research of this experiment, the foundation has been laid for the high-precision molding of the light-cured ZrO2 ceramic slurry.
