Synergism of Composition of Nitrogen- and Sulfur-Containing Compounds as a Tribological Active Additive to Lubricants

摘要

A composition containing ammonium salt of alkyldithiophosphoric acid with tetra(2-ethylhexyl) thiuramdisulfide is proposed as an effective tribological additive for lubricants. In addition, it provides a lower amount of sulfate ash, phosphorus, and sulfur in the motor oil. The composition demonstrates synergism if a fixed atomic ratio of sulfur to phosphorus is observed.
