摘要: 随着增材制造技术在陶瓷材料制备领域的快速应用,开发具有高固相含量、低黏度的光固化陶瓷浆料成为多种陶瓷材料复杂结构增材制造的关键内容。以Si3N4基陶瓷复合材料为对象,系统研究高固/低粘多元复相陶瓷浆料的制备与性能优化。概述了浆料体系的设计思路,包括树脂基体配方、颗粒级配策略和添加剂优化:设计HDDA、TMPTA、ACMO与EA混合树脂(质量比1:1:1:1);采用陶瓷颗粒粒径级配策略(颗粒质量比1 μm:0.5 μm:50 nm=0.17:0.67:0.16);优化硅烷偶联剂KH560含量(质量分数为陶瓷颗粒总质量的5%)、分散剂BYK110含量(质量分数为陶瓷颗粒总质量的4%)、稀释剂NMP含量(质量分数为树脂质量的20%)。最终实现浆料流变性和可打印性全面提升,在55.56%固相含量下浆料黏度0.79 Pa·s、触变性553.1 Pa/s、屈服应力28.9 Pa;KH560、BYK110和NMP的添加,使浆料固相含量达到74%时,黏度降至3.87 Pa·s。本研究为高性能陶瓷零件增材制造适用浆料的制备提供了理论与技术支撑。

Abstract: With the rapid application of additive manufacturing technology in the field of ceramic material fabrication, the development of light cured ceramic slurries with high solid content and low viscosity has become a key content in the complex structure additive manufacturing of various ceramic materials. This article focuses on Si3N4 based ceramic composite materials and studies high solid content/low viscosity multiphase ceramic slurries that meet the requirements of photopolymerization additive manufacturing, providing theoretical and technical support for the additive manufacturing of high-performance ceramic parts. The design concept of the slurry system is outlined, including the resin matrix formulation, particle grading strategy, and additive optimization. A composite resin matrix is designed and prepared by mixing the monomer resins HDDA, TMPTA, ACMO, and EA in a mass ratio of 1:1:1:1. A ceramic particle size grading strategy is adopted (particle mass ratio of 1 μm : 0.5 μm : 50 nm = 0.17 : 0.67 : 0.16). The contents of the silane coupling agent KH560 (5% of the total ceramic particle mass), dispersant BYK110 (4% of the total ceramic particle mass), and diluent NMP (20% of the resin mass) are optimized. This ultimately achieved comprehensive improvement in the slurry's rheological properties and printability. At a solid loading of 55.56%, the slurry exhibited a viscosity of 0.79 Pa·s, thixotropy of 553.1 Pa/s, and yield stress of 28.9 Pa. The addition of KH560, BYK110, and NMP reduced the slurry viscosity to 3.87 Pa·s even when the solid loading reached 74 wt%. This study provides theoretical and technical support for the preparation of applicable slurries used in additive manufacturing of high-performance ceramic components.
