摘　　要：在氧化锆陶瓷的凝胶注模成型制备中,为了消除空气中坯体表面脱粉现象,试图在常用的丙烯酰胺体系的基础上增加了一种新的水溶性聚合物组分,形成一种新型的聚合物-单体共存的凝胶注模成型体系。这种体系在某种条件下要优于原有单一丙烯酰胺体系,通过研究添加聚乙二醇对氧化锆悬浮体的分散特性、固化特性及其流变行为的影响,结果表明,添加1.5wt%水溶性聚合物聚乙二醇发现可以消除坯体的表面脱粉,同时大大地改善了氧化锆浓悬浮体的分散性和流动性。A new polyethylene glycol/acrylamide-based gelcasting system has been developed,which performs at least as well as, or in some cases better than, the original one. Its development is for the sake of eliminating the surface-exfoliation phenomenon of green body gelcast in air. This study concentrates attention on dispersion, gelation and theological behavior append water-solubility macromolecule polyethylene glycol in the new system. The results show that eliminating the surface-exfoliation phenomenon of green body gelcast and improve dispersion and rheological property of the Concentrated zirconium Suspension via append 1.5wt% Polyethylene Glycol.
