The Screening Effect of Ethanol Amines and Cholesteric Liquid Crystal Nanomaterials upon Friction Interaction with Metals in Plastic Lubricants

Abstract

The embedding of ethanol amines and cholestetic liquid crystal nanomaterials is experimentally found to improve the screening effect of general-purpose calcium plastic lubricants. A particular enhancement of this effect is pronounced in plastic lubricants where conventional industrial oils as the dispersion medium are replaced by petroleum refining products, such as petroleum vacuum distillates, which have been exposed to no special purification. This is due to the fact that petroleum vacuum distillates are based on the active naphthenic acids that form the boundary lubricant layers with high screening properties upon interaction with ethanol amines and cholesteric liquid crystal nanomaterials, which ensure the lower friction and wear of conjugated surfaces.
