The invention discloses a kind of rare earth lubricating oil and preparation method thereof, the rare earth lubricating oil specifically includes 1%~2% nano-graphene, yttrium oxide/lanthana nanoparticle of 3%~10% polymethyl methacrylate cladding, 5.7%~10% borate, 2%~8% surfactant, 3%~10% friction improver, 2%~10% dimethyl succinate, 0.3%~10% dimethyl glutarate, 45%~65% lubricating base oils, it is organically-modified by having been carried out to the rare earth compound of addition, improve the dispersibility in base oil, rare earth compound has " friction catalytic cracking " effect to the decomposition of boride simultaneously, increase friction surface activated boron atoms, to improve the surface hardness and wear-resisting property of material, and then generate the effect of collaboration lubrication, it is prepared by the present invention dilute Native lubricating oil is due to containing rare earth element, and the not corrosive substances such as sulfur-bearing, phosphorus, does not damage to parts itself, and generation environment does not pollute, and can be widely applied to industrial production. |
