LUBRICATING OIL FOR AUTOMOTIVE AND INDUSTRIAL APPLICATIONS, CONTAINING DECORATED GRAPHENE

摘要

This patent relates to a lubricating oil with added decorated graphene nanoparticles, which is called nanolubricant. This nanolubricant has automotive and industrial applications and offers as major benefits, simultaneous improvements in the thermal, rheological and tribological properties of the lubricant used as base fluid. Additionally, this nanolubricant offers a rheopectic behavior from a specific concentration, the same behavior that gives it the ability to increase its viscosity over time provided it is subjected to a constant cutting rate. Finally, the decorated graphene may include metallic, ceramic or polymeric nanoparticles, in a concentration range of 0.5% weight/weight to 2% w/w without changing the newtonian fluid behavior of the base lubricant, whereas for concentrations greater than 2% weight/weight and up to 3% weight/weight, the aforementioned rheopectic behavior will be observed.
