LUBRICATING OIL FOR AUTOMOTIVE AND INDUSTRIAL APPLICATIONS, CONTAINING DECORATED GRAPHENE.

摘要

The invention relates to a lubricating oil comprising nanoparticles of decorated graphene, called a nanolubricant. Said nanolubricant has automotive and industrial applications and its main advantages consist in simultaneous improvements in the thermal, theological and tribological properties of the lubricant used as a base fluid. In addition, said nanolubricant exhibits a rheopectic behaviour based on a specific concentration, the same behaviour which provides the capacity to increase the viscosity thereof over time while being subjected to a constant cutting rate. Furthermore, the decorated graphene can include metal, ceramic or polymer nanoparticles, and the concentration thereof can be between 0.5 % weight/weight and 2 % weight/weight without the base lubricant changing the Newtonian fluid behaviour thereof, while for concentrations higher than 2 % weight/weight and up to 3 % weight/weight, the above-mentioned rheopectic behaviour is observed.
