可生物降解液压油的研究进展

介绍了可生物降解液压油概念,它的组成包括基础油和添加剂。可生物降解液压油主要研究方向集中在筛选和开发新基础油方面,添加剂的研究还处于起步阶段。文中详细总结了以植物油、改进植物油、合成酯、聚醇醚、聚甲基烯烃及其多种混合物作为基础油的可生物降解液压油研究进展。研制开发性能好、成本低的可生物降解基础油与可生物降解添加剂是今后的发展趋势。

Research Progress of Biodegradable Hydraulic Oils

The biodegradable hydraulic oils are comprised of base oils and additives.The major attentions of research are focused on the selection and development of new base oils,while the research of biodegradable additives is still in primary stage.The base oils can select vegetable oils,modified vegetable oils,synthetic polyol esters,polyol ethers,polymethyl alkenes,etc.as well as their mixtures.In this paper,the research progress of biodegradable hydraulic oils based on these base oils is summarized in detail.It ...
