摘　　要：　本文研究了应用于陶瓷注射成形技术的聚乙烯醇缩丁醛 (PVB)基粘结剂体系 ,它主要包括PVB、邻苯二甲酸二辛酯 (DOP)、润滑剂和偶联剂。该粘结剂体系与Al2 O3粉末有较强的相互作用 ,可以制备混炼均匀和高固含量的Al2 O3陶瓷注射料 ,并且注射料具有高的生坯强度和良好的注射成形性。根据该粘结剂体系的TGA曲线 ,可以选择合适的热脱脂程序 ,经热脱脂和烧结得到结构致密的陶瓷制件。This paper focused on the binders mainly composed of PVB, DOP, Wax, which can be applied in ceramic injection molding and debinded through thermo debinding process. Al_2O_3 feedstock with comparatively high solid percentage can be prepared with the binders and the strength was high enough to meet the demand of next-step thermo debinding. The rheology of feedstock was studied and the procedure of thermo debinding was designed according to TGA.
