摘　　要：以T400,T110,200DN 3种环烷基油及MVI500,150BS,PAO8为基础油、超微化前后有机膨润土为稠化剂制备膨润土润滑脂,考察所制润滑脂的稠度、剪切安定性、胶体安定性、抗水淋性能和抗磨减摩性能。结果表明,超微化后膨润土制备的润滑脂的主要性能较传统膨润土润滑脂有明显改善,且不同基础油对超微化膨润土润滑脂的性能影响较大,以T110为基础油制备的超微化膨润土润滑脂具有较好的剪切安定性、抗水淋性能和抗磨性。The bentonite greases were prepared with six kinds of oil, T400, Tl10, 200DN, MVIS00, 150BS and PAO8 as the base oil, with bentonite powders before and after ball-milling as thickening agent. Their thickness, shear stability, colloid invariability, water resistance, anti-wear and antifriction properties were researched. The results show that the ultrafine bentonite grease has improved in most performances compared with the traditional one. And the base oils have huge influences on the performance of ultrafine bentonite greases. The ultrafine bentonite grease prepared with the base oil of Tl10 has good shear stability, water resistance and anti-wear property.
