摘要:
表面修饰对于纳米二氧化硅润滑脂的成脂能力和使用性能影响较大,以KH570、正辛醇、六甲基二硅胺烷为改性剂对纳米二氧化硅进行了表面修饰,制备了改性纳米二氧化硅润滑脂。结果表明,与未改性的纳米二氧化硅润滑脂相比,改性后抗老化硬化、抗水性及机械安定性等性能更优,每种改性剂有最适宜改性条件,KH570改性的纳米二氧化硅润滑脂综合性能最好。
关键词: 纳米二氧化硅, 表面修饰, 润滑脂, 正交试验
Abstract:
Surface modification has a great influence on the preparation and performance of nano silica lubrication grease. This study examined nano silica lubrication grease made with four nano silica, with and without surface modification by KH570, 1-octanol, hexamethyldisilizane. Results show that nano silica lubrication grease with surface modification can overcome the shortage of excessive age-hardening, poor water resistance, poor mechanical stability, each modifier has a suitable modification condition, the nano silica lubrication grease modified with KH570 shows the best performance.
Key words: nano silica, surface modification, lubricationg grease, orthogonal experiment
