Abstract

Compositions of ashless thio compounds in mixtures with mineral oil and metal-containing detergents were tested as antiwear additives representing variants of model engine oil compositions. The tribological activity for both fresh and oxidized mixtures, in comparison with the efficiency of the industrial additive zinc dialkyldithiophosphate, was investigated using different tribometers that realize different wear conditions for friction pairs. Synergy is noted in the antiwear action of amine salt compositions of dialkyldithiophosphoric acid and methylene-bis-dibutyldithiocarbamate, which in turn ensures the ecological safety of lubricants—low sulfate ash and phosphorous contents.

在无灰含硫化合物作为润滑剂的抗磨添加剂组成的组合物中的协同作用

摘要

测试了与矿物油和含金属清净剂的混合物中的无灰硫代化合物的组成，作为抗磨添加剂，代表了模型发动机油组成的变体。与工业添加剂二烷基二硫代磷酸锌锌的效率相比，使用不同的摩擦计研究了新鲜混合物和氧化混合物的摩擦学活性，所述摩擦计实现了摩擦副的不同磨损条件。在二烷基二硫代磷酸和亚甲基双二丁基二硫代氨基甲酸酯的胺盐组合物的抗磨作用中注意到了协同作用，这反过来又确保了润滑剂的生态安全性—低硫酸盐灰分和磷含量。
