preparation example Construction

[0021] In this embodiment, the preparation method of the lubricant includes the following steps: after uniformly mixing the components according to the set weight percentage, heating to a temperature of 60-80°C, and then stirring and dissolving; this preparation method operates Simple, less process, and the prepared lubricant has excellent extreme pressure, wear resistance and stability, and high temperature resistance, which is suitable for wide application. The use of this heating temperature range is conducive to properly reducing the viscosity of raw materials, and It does not affect the performance of the final lubricant. Properly raising the temperature and reducing the viscosity is beneficial to shorten the stirring and dissolving time. The stirring and dissolving is sufficient and the mixing is uniform, so that a lubricant with excellent performance can be finally prepared.

Abstract

In the extreme pressure anti-wear lubricant for large bush shafts and gears provided by the present invention, the raw materials of the lubricant include the following components by weight percentage: PAO100 oil 23%-27%, 150BS oil 55%-65%, chlorine Paraffin wax 4%~6%, drawing agent 0.2%~0.4%, gear oil compounding agent 1.5%~2.5%, polyester 4%~6%, benzotriazole 0.6%~0.8% and T701 1.5%~2.5%, The total amount of the above-mentioned raw material components is 100%. The present invention provides the determined raw material components and the determined ratio relationship between the raw material components. The lubricant prepared by using the above raw material components has excellent extreme pressure and wear resistance and stability, and has a long service life, and is very suitable for use in Lubrication of large bearing shafts and gears; in the prepared lubricant, each raw material component does not function in isolation, nor does it play a single role. In addition to its own excellent performance, each raw material component There is also a very good mutual synergy between them, and they can play a good role in synergy.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to an extreme-pressure anti-wear lubricant for large tile shafts and gears. Background technique [0002] Lubricant is a lubricating medium used to reduce the frictional resistance of the friction pair and slow down its wear. With the development of modern mechanical equipment in the direction of high speed, high load, and high temperature, the lubrication conditions of equipment become more and more harsh. When selecting a lubricant, it is generally necessary to consider many factors such as the movement of the friction pair, the material, the surface roughness, the working environment and working conditions, and the performance of the lubricant. Gears and large tile shafts are relatively common parts in modern mechanical equipment, and they are usually subject to greater friction during use, but the existing lubricants for large tile shafts and gears are extremely pressure-resistant The...
