摘要：

通过聚氨酯发泡法制备了ZrO2多孔陶瓷，研究了ZrO2粉体表面改性对多孔陶瓷综合性能的影响。结果表明：ZrO2粉体表面进行硬脂酸改性不仅可以阻止颗粒团聚，有效降低浆料黏度，并显著提高粉体表面的亲油性，增加粉体与有机聚氨酯原料的相容性，还可增加粉体与聚氨酯官能团的相互作用，促进聚氨酯交联网络形成，进而解决坯体及多孔陶瓷的分层问题，提高ZrO2多孔陶瓷的力学性能。当使用0.75%硬脂酸改性的ZrO2粉体时，所得多孔陶瓷无分层，孔结构完整，其抗压强度明显增加，为未改性ZrO2粉体所得多孔陶瓷的3倍。

This paper was to investigate the preparation of porous ZrO2 ceramic via the expansion of a ceramic suspension by polyurethane (PU) foam system. The effect of stearic acid modification on the properties of porous ceramic was investigated. The results show that the compatibility of the system is improved due to the enhancement of hydrophobicity, the agglomeration of particles is restrained, the viscosity of the slurry is decreased and the formation of network is promoted due to the interaction between ceramic powders and functional groups of polyurethane after the modification. The addition of stearic acid can solve the delamination problem of green body and improve the mechanical properties of ZrO2 ceramic. When the addition of stearic acid is 0.75%, ZrO2 ceramic has good mechanical properties due to the complete pore structure with no delamination. The compressive strength of modified ZrO2 ceramic is three times greater than that of unmodified ZrO2 ceramic.
