Problems solved by technology

In the actual workplace, gears are often damaged due to factors such as lubrication, anti-wear, and ambient temperature.
[0003] At present, there are few lubricating grease anti-wear additives at home and abroad, the price is also very expensive, the preparation process is complicated, the versatility is poor, and the effect is not good
As the nano-diamond powder used in CN101029264, prepared by negative oxygen balance method and functional group modification method, the steps are cumbersome and expensive, which is not conducive to large-scale industrial production

Abstract

The invention discloses a gear wear-resisting lubricating grease composition and a preparation method thereof. The gear wear-resisting lubricating grease composition comprises the following components in parts by weight: 70-90 parts of base oil, 5-20 parts of a thickening agent, 2-5 parts of an antioxidant, 1-10 parts of an anticorrosive agent, 2-6 parts of carbon black and 1-10 parts of an anti-wearing agent. The lubricating grease disclosed by the invention is very good in wearing resistance, and the friction coefficient of a gear can be effectively reduced and the service life of the gear is prolonged when the lubricating grease is used.

Description

technical field [0001] The invention belongs to the field of lubricants, in particular to a wear-resistant lubricating grease for gears and a preparation method thereof. Background technique [0002] Grease is composed of base oil, thickener and other performance additives. It mainly plays the role of reducing mechanical friction and preventing mechanical wear. It is widely used in gear applications. With the development of modern industry and the continuous emergence of high-end precision equipment, it is necessary for The requirements for gear grease are getting higher and higher. In addition to good wear resistance, it is also required to be applied under conditions such as corrosion, high temperature, and high load. However, in actual workplaces, gears are often damaged due to factors such as lubrication, anti-wear, and ambient temperature. [0003] However, there are few lubricating grease anti-wear additives at home and abroad at present, the price is also very expen...
