Abstract

The invention relates to a lubricating oil additive, comprising base oil, a solid lubricating material, a far-infrared ceramic material, a detergent, an oxidation and corrosion inhibitor, a stabilization dispersant, and an antioxidant anti-friction agent. The invention further relates to a preparation method of the lubricating oil additive. The lubricating oil additive provided by the invention contains the ceramic powder material capable of emitting far-infrared ray, can uniformly disperse the solid lubricating material in the base oil, and thus the stabilization dispersibility of the solid material is significantly raised, the lubrication effect of the lubricating oil is enhanced, the phenomenon that the lubricating oil viscosity is decreased under service conditions is improved, the service life of the lubricating oil is raised, and the lubricating oil additive can be widely used in internal combustion engine oil and engine oil with substantial effect. The preparation method has the advantage of simple process and is easy to operate.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil additive and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in my country has increased significantly, and the problems of automobile energy consumption and environmental protection have attracted great attention from the whole society. The fuel combustion efficiency and lubrication and wear conditions of the automobile engine under the service conditions have the most significant impact on the energy consumption and environmental protection of the automobile, and put forward higher requirements for the lubricating performance and long-term stability of the lubricating oil. [0003] Chinese invention patent application 200810013237.8 discloses a self-repairing superfine ore powder lubricating oil additive, which is composed of quartzite superfine powder and surfactant, wh...
