Feed material for injection molding of nano zirconium-based ceramic as well as preparation method and application of feed material
The invention relates to the technical field of ceramic injection molding, and provides a feed for nano zirconium-based ceramic injection molding as well as a preparation method and application thereof. The feed is supported by ceramic raw material powder and an organic mixture, the ceramic raw material powder comprises nano zirconium oxide powder, aluminum oxide powder and yttrium oxide powder, and the organic mixture comprises a coupling agent, an adhesive and a dispersing agent. According to the preparation method, a hydrothermal method is originally introduced to pre-treat the ceramic raw material powder, and two coupling agents are combined for modification, so that the dispersity and the flowability of the raw materials are improved, and the yield and the bending strength of the nano zirconium-based ceramic are improved. Meanwhile, a mixed process of solvent degreasing and microwave heating degreasing is adopted, so that the degreasing effect is improved. The feed for injection molding of the nano zirconium-based ceramic, which is high in solid content and good in flowing property, is prepared, and the prepared nano zirconium-based ceramic has the advantages of being low in manufacturing difficulty, high in yield, low in cost and the like.
本发明涉及陶瓷注射成型技术领域，提出一种纳米锆基陶瓷注射成型用喂料及其制备方法和应用。上述喂料包括由陶瓷原料粉末和有机混合料支撑，陶瓷原料粉末包括纳米氧化锆粉末、氧化铝粉末，氧化钇粉末，有机混合料包括偶联剂、粘接剂和分散剂。本发明独创性的引入水热法对陶瓷原料粉末进行预处理，并采用两种偶联剂组合进行改性，提升了原料的分散性和流动性，提升了纳米锆基陶瓷的成品率和弯曲强度。同时，本发明采用溶剂脱脂和微波加热脱脂的混合工艺，提升了脱脂效果。本发明制备了高固相含量且具有良好流动性能的纳米锆基陶瓷注射成型用喂料，制备的纳米锆基陶瓷具有制造难度低，良品率高，成本低等优点。
