摘　　要：综合分析了各种润滑油的生物降解性能与其结构及组成的关系。通过研究植物油的物性及其润滑机理 ,指出植物油作为润滑油的基础油料是一种可再生资源。由于植物油分子中含有酯基和不饱和的双键结构 ,其氧化安定性和水解稳定性较差 ,是其用作润滑油的瓶颈 ,但可以通过简单的化学处理如氢化和酯交换来提高其氧化安定性。考虑添加剂在基础油中的感受性及其对生态环境的影响也是非常重要的。The relationship between biodegradability of varied lubricants and their structures and compositions is analyzed. Vegetable oil, which is a renewable resource, is recommended as an alternative basic oil of lubricant by investigating plant oil properties and its lubricating mechanism. Vegetable oil oxidation stability is poor, which is the bottleneck of being lubricant, due to containing ester and unsaturated olefinic bond. Some chemical treatment as hydrogenation and ester exchange are utilized to increase its oxidation stability. Consideration of the sensitivity of additives in basic oil and its effect on ecological environment is also very important.
