Abstract

The protective properties and temperature resistance of sulfonate greases based on petroleum oil KS-19 have been assessed. Highly alkaline calcium sulfonates of Russian and foreign production are used as thickeners for such greases. Sulfonate greases have been shown to have good protective properties. It has been established that the ability of sulfonate greases to prevent corrosion depends on the protective properties of calcium sulfonate used as a thickener. Based on the totality of the indicators obtained, the grease based on the Russian-made K-314 thickener has the best properties; in temperature resistance, it is superior to the sample on the foreign thickener Lubrizol 86 GR, and in terms of protective properties, it is on the same level with it.

磺酸盐润滑脂的防护和摩擦学特性

摘要

对基于石油 KS-19 的磺酸盐润滑脂的防护性能和耐温性进行了评估。俄罗斯和国外生产的高碱性磺酸钙用作此类润滑脂的增稠剂。磺酸盐润滑脂已被证明具有良好的保护性能。已经确定，磺酸盐润滑脂的防腐蚀能力取决于用作增稠剂的磺酸钙的保护性能。综合所得指标，以俄制K-314稠化剂为基础的润滑脂性能最好；耐温性能优于国外增稠剂Lubrizol 86 GR样品，防护性能与其处于同一水平。
