植物油基润滑剂的氧化

作为一种环境友好润滑剂，植物油具有良好的生物降解能力、可再生性和优良的润滑性能。然而，植物油在热氧化稳定性、低温性能和粘温性能上的缺陷却制约了其在工业上的应用。从氧化机理的角度，分析和研究了植物油氧化产物，并讨论了氧化产物对植物油润滑性能的潜在影响，以及提高植物油氧化安定性的方法。

Oxidation of Vegetable Oil- based Lubricants

As an environmentally favorable lubricants, vegetable oils are possessed of good biodegradability, renewability and excellent lubricity. However the defects of vegetable oils on thermal - oxidative stability, low - temperature property and viscosity - temperature performance limit their applications in industrial field. Base on the oxidative mechanism, it is analyzed and researched the oxidative products of vegetable oils, and discussed the potential impact of such oxidative products on lubricity, the methods of improving oxidative stability of vegetable oils as well.
