摘要:
光固化3D打印陶瓷技术与传统陶瓷成形工艺相比，具有成形精度高、生产周期短、成本低等优点，为复杂结构陶瓷型芯的制备提供了一种可靠的成形工艺。该工艺制备高性能陶瓷的关键在制备低粘度、高固含量、均匀稳定的陶瓷浆料，小尺寸陶瓷颗粒的加入在提高陶瓷构件性能的同时，带来浆料分散性差、粘度大、固化性能差等问题。针对该问题，目前最有效的解决措施是在陶瓷浆料中添加分散剂，利用分散剂空间位阻和静电排斥机制，改善氧化物陶瓷颗粒与油性光敏树脂不相容的问题，增强陶瓷颗粒间排斥作用，减少陶瓷颗粒间的团聚从而实现低粘度、高固含量、均匀稳定陶瓷浆料的制备。总结了目前国内外利用分散剂改善光固化3D打印陶瓷浆料的研究进展，对陶瓷浆料的分散剂选用规则进行了概述，为制备均匀稳定的高固含量3D打印陶瓷浆料提供了理论基础。
Abstract:
Compared with the traditional ceramic preparation technology, the stereolithography 3D printing technology has the advantages of high molding accuracy, short production cycle and low cost, which provides a reliable forming process for the preparation of complex structural ceramic components. The key to high-performance ceramic core via the stereolithography 3D printing lies in the prepare ceramic slurry with high solid loading, low viscosity and uniform stability. The addition of small size ceramic particles can improve the performance of ceramic components, but it also causes the poor dispersion, high viscosity and insufficient curing depth of the slurry. To solve these problems, the most effective method is to add dispersant in ceramic slurry, utilizing steric hindrance and electrostatic repulsion mechanism of dispersant, the incompatibility between oxide ceramic particles and oily photosensitive resin can be alleviated, the repulsion between ceramic particles can be increased, and the agglomeration between ceramic particles can be reduced, so as to realize the preparation of ceramic slurry with low viscosity, high solid loading and uniform stability. In this paper, the domestic and international research progress of using dispersant to improve the stereolithography 3D printing ceramic slurry status was summarized, and the selection rules of dispersants for preparation of ceramic slurry were summarized, which provided a theoretical basis for the preparation of uniform and stable 3D printing ceramic slurry with high solid loading.
