Abstract
Provided is a lubricating oil composition including a lubricating oil additive and a lubricating oil, the lubricating oil additive having nanodiamonds, of which a surface is hydrophobically modified by a surface treatment, dispersed in a base oil. The lubricating oil composition retains dispersibility over a long period of time and thus can ensure storage stability. Machines to which the lubricating oil composition is applied may have improved abrasion resistance as well as improved fuel consumption and reduced noise, and high thermal conductivity of the lubricating oil composition may also increase cooling efficiency and the service life of machines.
Claims11
A lubricating oil additive comprising:
- a plurality of nanoparticles;
- and
- base oil in which the plurality of nanoparticles are dispersed,
- wherein each of the plurality of nanoparticles comprises a core and a shell surrounding the core,
- wherein the core comprises a nanodiamond, and the shell comprises at least one of an unsaturated fatty acid and an amine-based compound, and
- wherein a thermal conductivity of the core is greater than a thermal conductivity of the shell, and the thermal conductivity of the shell is greater than a thermal conductivity of the base oil.
