METAL-CLADDING MULTIFUNCTIONAL COMPOSITION FOR ENGINE, TRANSMISSION AND INDUSTRIAL OILS Russian patent published in 2023 - IPC C10M141/06 C10M129/26 C10M133/12 C10M133/16 C10N10/00 C10N30/00 

FIELD: oils.

SUBSTANCE: invention relates to lubricants based on mineral and synthetic oils containing a metal-cladding multifunctional composition made to enhance anti-friction, anti-scuffing, antioxidant, detergent and dispersing properties, and can be used in internal combustion engines (ICE) of trucks and light motor vehicles, locomotives, river and marine fleets, as well as in transmission and industrial oils. Proposed is a metal-cladding oil-soluble additive consisting of the following components wt.%: organic acid metal salt produced through the reaction of industrial oleic acid constituting a mixture of carboxylic unsaturated acids C₁₅-C₁₈ with monovalent copper oxide 3 to 10; aromatic amine 15 to 35; derivative of succinimide 45 to 65; oil-soluble organic acid in the form of oleic acid 5 to 15.

EFFECT: possibility of preventing damage to oil channels of the lubrication system of internal combustion engines and improving the anti-wear properties, ensuring long-term performance capacity of the friction pair at a sliding speed of up to 2.46 m/s.
