Abstract—

The article notes that the use of electric contact grease is one of the effective methods for improving the reliability of connections in electrical engineering, which is relevant due to the rapid development of electric transport and increasing requirements for the environmental friendliness of lubricants. Тhe production of grease, which, in addition to tribological efficiency, has electrically conductive properties in a tribosystem, can be achieved by providing a stable dispersed system with a high content of solid lubricants and electrically conductive components. The effect of introducing the electroconductive particles into the grease composition to provide electrically conductive properties was studied. Technological methods for obtaining the electric contact grease have been developed. It has been established that with an increase in the content of electroconductive filler in grease, the wear index and colloidal stability decrease with an increase in the dropping point and shear strength. The optimal content of the electroconductive filler was determined while maintaining the required tribological and physicomechanical characteristics of the electric contact grease. The prospects of using biodegradable oils as the basis for greases are noted.

电接触脂的功能特性

摘要:本文指出，随着电力运输的快速发展和对润滑剂环保性要求的不断提高，使用电接触脂是提高电气工程连接可靠性的有效方法之一。Тhe润滑脂的生产，除了具有摩擦学效率外，在摩擦系统中还具有导电性能，可以通过提供具有高含量固体润滑剂和导电成分的稳定分散系统来实现。研究了在润滑脂组合物中引入导电颗粒对润滑脂导电性能的影响。开发了制备电接触脂的工艺方法。结果表明，随着润滑脂中导电填料含量的增加，润滑脂的磨损指数和胶体稳定性随滴点和抗剪强度的增加而降低。在保持电接触脂所需的摩擦学和物理力学特性的同时，确定了导电填料的最佳含量。指出了生物可降解油作为油脂基础的发展前景。
