摘　　要：润滑油添加剂是一种非常重要的五硫化二磷下游产品,对五硫化二磷行业发展具有重要作用。为了促进五硫化二磷行业发展,开展了五硫化二磷制备润滑油添加剂的研究。研究表明:在五硫化二磷下游产品中,润滑油添加剂是对五硫化二磷需求量较大的高端产品,占五硫化二磷总需求量的比重较大,且对五硫化二磷的产品质量要求较高。以五硫化二磷为原料制备的润滑油添加剂主要具有摩擦改善、黏度指数改进、抗磨、分散和抗氧化等功能,按功能可分为单功能润滑油添加剂和多种功能润滑油添加剂。单功能润滑油添加剂可显著改进润滑油在一定方面功能,但若需改进润滑油多方面功能时,需添加多种具有单功能的添加剂,添加剂使用量大,使用不便,成本较高;多功能润滑油添加剂可以单一添加剂实现对润滑油在多方面功能的改进,添加剂使用量小,使用简便,成本较低。多功能添加剂是润滑油添加剂未来发展的趋势和热点,应着重利用五硫化二磷制备多功能润滑油添加剂的应用开发。The lubricating oil additives which are very important downstream products from phosphorous pentasulfide play a very important role on the development of phosphorous pentasulfide industry.For promoting the development of phosphorous pentasulfide industry,the study on preparation of lubricating oil additives with phosphorous pentasulfide was conducted.It can be shown from the study that lubricating oil additives which are the high-end products in the downstream products of phosphorous pentasulfide have a large consumption of phosphorous pentasulfide which have a large ratio in the total consumption of phosphorous pentasulfide.And the quality of phosphorous pentasulfide used for preparatiing lubricating oil additives must be high.The lubricating oil additives from phosphorous pentasulfide mainly have functions such as friction improvement,viscosity index improvement,wear resistance,dispersion,oxidation resistance and so on,and can be classified to single-function lubricating oil additives and multifunction lubricating oil additives.Although the single-function lubricating oil additives can improve significantly single function of lubricating oil additives,there are disadvantages for the single-function lubricating oil additives,such as many various types and large consumption of single-function lubricating oil additives,inconvenient use and high cost and so on,when multiple functions of lubricating oil need to be conducted.While multiple functions of lubricating oil can be realized using a multifunction lubricating oil additive with smaller consumption of multifunction lubricating oil additive,convenient use and high cost and so on.The multifunction lubricating oil additives are the trend and hotpot of development of lubricating oil additives,Therefore,the more attentions should be put on preparation of multifunction lubricating oil additives with phosphorous pentasulfide.
