摘要: 基于光固化3D打印技术需要高固相含量、低黏度的陶瓷浆料以防止烧结陶瓷部件产生裂纹、孔洞、翘曲等缺陷,通过测试流变性能与固化性能,本文优化了树脂单体的选用及配比,采用KH550、KH560、KH570三种硅烷偶联剂对Al2O3粉体表面改性,以改善陶瓷浆料的流变性能和稳定性,探讨了硅烷偶联剂降低Al2O3陶瓷浆料体系黏度的机理,获得了固相含量为75%(质量分数)(体积分数为45.5%)、黏度为4 540 mPa·s的Al2O3陶瓷浆料,并提出了一种光固化Al2O3陶瓷浆料制备的优化方法,这有望对用于制备复杂陶瓷的高固含量、低黏度的3D打印Al2O3陶瓷浆料提供帮助。

Abstract: In order to prevent cracks, holes, warpage and other defects in sintered ceramic parts, ceramic paste with high solid content and low viscosity is needed based on light-curing 3D printing technology. By testing the flow and curing proformances, the selection and ratio of resin monomers were optimized. KH550, KH560 and KH570 were used to modify the surface of Al2O3 powder to improve flow performance and stability of ceramic paste. The mechanism of silane coupling agent reducing the viscosity of Al2O3 ceramic paste was discussed. Al2O3 ceramic paste with a solid content of 75% (mass fraction) (volume fraction of 45.5%) and a viscosity of 4 540 mPa·s was obtained. An optimization method for the preparation of light-curing Al2O3 ceramic paste was proposed, which is expected to be helpful for the preparation of 3D printing Al2O3 ceramic paste with high solid content and low viscosity for complex ceramics.

Key words: light-curing technology, alumina ceramics, paste optimisation, surface modification, silane coupling agent, 3D printing performance
