硫化添加剂综述

Summary of Sulfurized Additives

由于硫元素具有特殊的结构和性能,使得硫化添加剂在润滑油中被广泛使用。不同结构的硫化添加剂具有不同的 功能,在润滑油中起着极压,抗磨,减摩,清净,分散及中和等作用。随着对环境保护的日益重视和润滑油性能升级的需求,硫 化添加剂的使用将会受到越来越严格的限制。从结构、功能、使用中存在的问题以及发展趋势方面对硫化添加剂的状况进行 了综述,希望能对开发先进的多功能硫化添加剂提供帮助。

Because of the special structure and performance of sulfur,sulfurized additives were widely used in lubricating oils.The sulfurized additives with different structures had different functions and played extreme pressure,anti-wear,friction reduction,cleaning,dispersion and neutralization roles in lubricating oils. With the increasing attention to environmental protection and the need for upgrading the performance of lubricants,the use of sulfurized additives would be more and more strictly restricted. The status of sulfurized additives was summarized from the aspects of structure,function,problems that existing in use and development trend. It was hoped that it would be helpful for the development of advanced multi-functional sulfurized additives.
