Abstract

The invention discloses high-wear-resistance lubricating oil, which is prepared from the following raw materials by weight: 80 to 90 parts of base oil, 2 to 3 parts of nano tungsten disulfide, 0.4 to0.6 part of a surfactant, 0.8 to 1 parts of a defoamer and 1.5 to 2 parts of an antiwear additive. The invention also discloses a preparation method of the lubricating oil. According to the lubricating oil, the nano tungsten disulfide is uniformly dispersed in the lubricating oil through the compounding of the nano tungsten disulfide and the surfactant, and the anti-wear and anti-friction effect of the nano-particles is exerted; by adding the anti-wear additive, a composite protective film is generated at the bearing friction interface and has excellent anti-wear and anti-friction performance;the lubricating oil is processed through special processing equipment, the lubricating oil can be fully, thoroughly and efficiently blended and processed so that components are evenly dispersed in the lubricating oil to exert corresponding effects and to ensure quality of the lubricating oil. The wear-resistant high-quality lubricating oil is obtained and suitable for tapered roller bearings, heavy-duty gear and other fields.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a high wear-resistant lubricating oil and a preparation method thereof. Background technique [0002] Tapered roller bearings, heavy-duty gears, etc. are widely used in various industries in the industrial field because of their remarkable advantages of bearing compound loads (both bearing radial force and axial force). In tapered roller bearings, there is a linear contact between the tapered rollers and the raceway. This contact method can distribute the load over a large area, so that the tapered roller bearing has good load carrying capacity. Heavy-duty gears maintain high-efficiency transmission even under heavy loads. Therefore, the performance requirements of lubricating oils necessary for the use of such bearings or gears are gradually increasing. Lubricating oil is used to reduce friction and protect machinery and processed parts as liquid or semi-so...
