润滑油结构组成与黏度及黏温特性的相关性分析

摘要

根据润滑油的不同分类及实际使用状况,结合国内外相关研究现状,主要从烃类和酯类润滑油的链结构以及取代基和官能团的类型、数量、位置等角度出发,对油品分子结构与黏度及黏温特性的相关性进行了综述.%According to the different classification and actual use of lubricating oil, combined with the research status at home and abroad, the correlation between the molecular structure and viscosity, viscosity-temperature characteristics of oil products was discussed from the aspects of chain structure of hydrocarbon and ester lubricants, and type, location and quantity of substituents and functional groups.
