Abstract

The invention belongs to the technical field of lubricating oil and discloses an automobile lubricating oil composition and a preparation method thereof. The composition consists of the following components in percentage by weight: 15 to 20 percent of medium-viscosity-index lubricating oil, 46 to 52 percent of high-viscosity-index lubricating oil, 7 to 12 percent of a viscosity index improver, 10to 13 percent of a complexing agent, 0.3 to 0.6 percent of a pour point reducer, 2 to 4 percent of an anti-abrasive agent and 8 to 12 percent of a special agent. The preparation method comprises the step of mixing the medium-viscosity-index lubricating oil, the high-viscosity-index lubricating oil, the viscosity index improver, the complexing agent, the pour point reducer, the anti-abrasive agentand the special agent uniformly to obtain the automobile lubricating oil. The automobile lubricating oil composition has good balance on lubricating property, extreme pressure wear resistance, temperature control property, corrosion and rust resistance and thermal oxidation stability.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil for vehicles, and in particular relates to a lubricating oil composition for vehicles and a preparation method. 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 role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering (Roab) . As long as it is applied between two relatively moving objects and can reduce the friction and wear of the two objects due to the function of contact, it is a lubricating oil. [0003] Lubricating oil generally consists of two parts: 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, endow some new properties, and...
