摘要：NOVELTY - The fluorine-containing rare earth nanometre-sized lube oil additive and its process for preparing. The invention comprises adopting organic surface to cover in the preparing nanoparticle course, recognizing the modifying agent as a part of the reaction system while synthesizing the particles, when the particles are formed, the particle surface adsorbs the modifying agent through the interface to form chelate polymer, then the modifying agent is covered on the particle surface evenly and tightly. The grain diameter of the nanoparticle prepared by backward microemulsification in this invention is of 12-17 nm, the rare earth nanoparticle covered by the organic surface can evenly steadily disperse in the base oil and the compounded synergistic effect with lube oil or other additives is good.
