NOVELTY - Lubricating oil friction modifier comprises base oil, nano-graphene, and nano-ceramic coupling agent. USE - Lubricating oil friction modifier used in methanol gasoline and diesel engine lubricating oil. ADVANTAGE - The lubricating oil friction modifier greatly improves the non-seizure loads (PB values) and weld load (PD value) of the gasoline engine four-ball machine test, effectively improves the anti-friction performance of the lubricating oil used by the engine, repairs wear and solves the problem of burning oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing lubricating oil friction modifier, which involves stirring the base oil, nano-graphene and nano-ceramic coupling agent uniformly at 60-70degrees Celsius, and then filtering and cooling the mixture with a 400-mesh filter screen.
