Abstract

The invention relates to automobile lubricating oil, which is prepared from the following ingredients of basic oil, molybdenum disulfide, lead isocaprylate, 2 to 5 parts of internal combustion engine compounding agents, anti-rust agents, nanometer graphite, nanometer zirconium oxide and the like. The automobile lubricating oil has the characteristics of good dispersing performance, good stability and good anti-friction and wear-resistant performance. The additive of zirconium oxide is enriched on the metal surface defect position, so that a layer of self-restoring lubricating film is built on the surface of a friction pair; the characteristics of good wear reduction performance and good self restoration performance are realized; the graphite is added, so that the mechanical friction is effectively reduced, machinery and processing components are protected; mechanical impurities, residue carbon, ash and sulphated ash cannot remain; the effect on a mechanical automobile is very obvious; the use is convenient; the manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to the technical field of automobile lubricating oil. Background technique [0002] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. However, there are many types of mechanical transmission, and the requirements for lubricating oil are also different. [0003] However, domestic automotive lubricating oil production technology focuses on the maintenance of automotive engines, focusing on the anti-friction and anti-wear properties of lubricating oil, quietness and dispersion, and high-temperature anti-oxidation performance. However, the development trend of lubricating oil technology in the world is to minimize friction, reduce energy loss, and thus reduce fuel consumption. According to estimate...
