Abstract

The invention discloses synthetic oil based lubricating oil having high wear resistance. The lubricating oil is prepared from components in parts by mass as follows: 1,200-1,560 parts of base oil, 91-112 parts of an additive, 10-45 parts of graphite, 10-30 parts of bentonite and 10-30 parts of a coupling agent, wherein the base oil is synthetic oil; the additive contains diamond nanoparticles. A little graphite and a little bentonite are contained in the formula, particularly, nitrogen-containing groups are introduced to the additive, the components have synergistic effect, the synthetic oil based lubricating oil has certain dispersing performance, shapes and sizes of paraffin crystals in the lubricating oil can be effectively improved, and the lubricating oil has a better pour point depression effect. Besides, the base oil is synthetic oil, the lubricating oil can be used at low temperature by the aid of the added diamond nanoparticles and the synergistic effect of the components, better wear resistance is kept, and the application range of the lubricating oil with the synthetic oil as the base oil is greatly enlarged.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a lubricating oil. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil products are usually used at very low ambient temperature, especially in winter and cold car conditions, so the lubricating oil used is required to have good low-temperature fluidity, which is not only conducive to the normal start-up and operation of the machine, but also reduces the Wear of the machine during start-up. [0003] However, at low temperatures, the crystals in the lubricating base oil crystallize out, forming a three-dimensional network structure and losing fluidity. In order to maintain the low-tem...
