Lubricating oil specially used for automotive chassis

Abstract

The invention discloses lubricating oil specially used for automotive chassis. The lubricating oil is prepared from the following raw materials in parts by weight: 60-80 parts of high viscosity base oil, 15-25 parts of modified nano-graphite, 3-7 parts of an antioxidant, 1-5 parts of an anti-wear agent, 18-28 parts of a pour point depressant and 14-20 parts of molybdenum thiophosphate. The lubricating oil is specially used for the automotive chassis; by adding additives in to the lubricating oil in a matching way, the lubricating oil can effectively remove thick black carbon mud particles on bearing parts, thus prolonging the service lives of bearings of the automotive chassis and reducing the maintenance cost of equipment; furthermore, the antioxidant is also added into the lubricating oil, so that the oxidation resistance of the oil product is improved, and the storage and service lives of the oil product are prolonged. The prepared lubricating oil shows excellent extreme pressure resistance and high carrying capacity, is good in wear resistance, and also can provide excellent long-acting lubricating property.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a special lubricating oil for automobile chassis. Background technique [0002] Lubricating oil refers to the liquid lubricant used in various types of automobile transmission, mechanical equipment, and precision instruments to reduce friction and protect machinery and processed parts. According to its source, it is divided into four categories: animal oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. , It is mainly used to reduce the friction between the surfaces of moving parts, and at the same time, it has the functions of cooling, sealing, anti-corrosion, anti-rust, insulation, power transmission, and cleaning impurities for machinery and equipment. At present, there are many solid lubricants with good performance, but due to their high density, they cannot be suspended in the oil, and the particle size is too coarse to get into the friction...

AI Technical Summary

Problems solved by technology

At present, there are many solid lubricants with good performance, but due to their high density, they cannot be suspended in the oil, and the particle size is too coarse to get into the friction pair. The agglomeration is serious, and the oil circuit is blocked after a long time, so they cannot be used in lubricating oil.
