Abstract

The invention relates to lubricating oil and belongs to the field of chemical industry. The lubricating oil is characterized by being prepared from the following raw materials in parts by weight: 120-180 parts of base oil of the lubricating oil, 8-12 parts of glycol tristearate, 8-20 parts of a viscosity index improving agent, 3-8 parts of octylphenol, 1-3 parts of a fluorinated surfactant, 3-13 parts of a silane coupling agent and 3-6 parts of diisocynate. A lubricating oil additive has relatively good compatibility with the base oil, and the viscosity index improving agent is added, so that the viscosity index of the lubricating oil is remarkably improved and the stability of the lubricating oil is improved; the production cost is relatively low and the service life of the lubricating oil is relatively long; and the lubricating oil has relatively good anti-freezing, anti-rusting, wear-resisting and lubricating performances.

Description

technical field [0001] The invention relates to a lubricating oil and belongs to the field of chemical industry. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is composed of base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil and endow some new properties. An important component of oil. However, the synergistic effect after the addition of additives is poor, while improving a certain performance, it will cause the reduction of another performance, resulting in the lack of a certain performance of the lubricating oil, affecting normal use. Contents of the invention [0003...
