摘要
润滑油作为机械运行不可缺少的材料,对维持机构的运行及提高机械寿命起到非常关键的作用.随着现代工业的不断进步,对机构运行寿命的要求越来越高,同时运行环境也越来越苛刻,这些均要求所采用的润滑油具有更为优异的综合性能.前期所采用的矿物基润滑油在耐温性、润滑性、抗氧化性、黏温性能等方面已经很难满足使用要求,因此需要采用合成润滑油.由于合成油采用人工合成的方式,其综合性能远高于普通矿物油,但目前合成油种类较多,不同种类的润滑油具有不同的性能及使用要求,因此本文介绍了常见的几种合成润滑油的国内外现状,并对合成润滑油的未来发展趋势进行了讨论和展望.
With the development of science and technology, lubricants with long service life, good degradability, high thermo- stability and ultra - low temperature properties are required in order to meet the demand for harsh working conditions. Meanwhile, the lubricants should have good comprehensive properties which mineral oils can not be possessed. Thus, the synthetic oils play more and more important role in modern industries. The properties, compositions and molecular structures of synthetic oils can be devised according to the requirements. Compared with mineral oils, the synthetic oils have good viscosity -temperature behaviour, good antioxidation, high thermo stability, good radio -resistance and good lubricating properties. In this paper, the preparation method and the properties of some synthetic oils were introduced. Furthermore, the research status and prospect of synthetic oils were also discussed.
