High-toughness lubricating oil

Abstract

The invention discloses a high-toughness lubricating oil which is prepared from the following raw materials in parts by weight: 2.5-7.1 parts of glycerin monostearate, 2.5-7.4 parts of chloroform, 1.5-3.3 parts of tetradecyl alcohol, 2.5-4.6 diethanolamine maleic anhydride composite ester, 15-22 parts of trimethylolpropane, 23-30 parts of industrial white oil and 1.3-2.6 parts of hydrofluoric acid. The components in the lubricating oil have the property of being firmly adsorbed to the metal surface, but mineral oil does not have such property; the polar molecules are adsorbed to the metal surface orientationally, and the base oil is stored in the molecular network, thereby forming the high-toughness lubricating film; and the lubricating oil disclosed by the invention can greatly enhance the abrasion resistance and maximum nonseizure load of gears in the service process, can stably perform the functions for a long time, and has favorable maintenance actions on various manual transmission cases and rear axle driven gears.

Description

technical field [0001] The invention relates to a high toughness lubricating oil, which belongs to the field of industrial chemical industry. Background technique [0002] The gear lubricating oil required for the manual transmission and rear drive axle of automobiles is a product with a large amount and a wide range of products. In addition to lubricity under specific conditions of use, it is also required to have excellent extreme pressure properties, oxidation stability, Wear resistance, shear stability, etc. Patent CN1209449 discloses a gear lubrication additive composition, including a certain amount of diluent, sulfur-containing extreme pressure additive, phosphorus-containing anti-wear additive, anti-rust additive, friction modifier, antioxidant or metal deactivator. In the existing gear oil technology, when selecting oily agents and extreme pressure antiwear agents, most of them use the traditional sulfur-phosphorus-chlorine-zinc system for mutual matching. Although...

Problems solved by technology

In the existing gear oil technology, when selecting oily agents and extreme pressure antiwear agents, most of them use the traditional sulfur-phosphorus-chlorine-zinc system for mutual matching. Although the anti-wear ability of gears can be improved to a certain extent, the effect is not good. Not ideal, and oil oxidation will increase rapidly after a period of time, greatly affecting the performance and life of the gearbox or rear drive axle
