Abstract

The invention provides low-temperature lubricating grease and a preparation method thereof. The low-temperature lubricating grease comprises mineral oil, synthesized oil, fatty acid soap, an antioxidant and an antirust agent. Compared with the prior art, the low-temperature lubricating grease is characterized in that semi-synthesized oil obtained by mixing III-type oil and ester oil and / or PAO (poly alpha olefin) oil is used as basic oil; the III-type oil has a high viscosity index and is high in high-temperature and low-temperature performance, oxidation stability, heat stability and evaporation performance; the ester oil and the PAO oil also have high viscosity indexes and are high in low-temperature performance; moreover, a mixture of lithium stearate and 12-hydroxy lithium stearate is used as a thickening agent for thickening the semi-synthesized oil, so that the low-temperature lubricating grease is high in low-temperature performance, and a used component can be normally lubricated under low temperature; the applicable temperature range is large; furthermore, the thickening agent is easy to synthesize.

Description

technical field

[0001] The invention belongs to the technical field of lubricating grease, and in particular relates to a low-temperature lubricating grease and a preparation method thereof. Background technique

[0002] When the aircraft is flying in various attitudes in the air, it can be manipulated flexibly and smoothly to achieve its specific technical performance. It is compatible with the ad hoc systems equipped in the airframe, such as the motors of each power system, various instruments indicating the flight status, The electric mechanism of each transmission system and the instruments, micro-motors, electrical appliances, etc. in various electronic instruments, which are collectively referred to as "airborne products" in the aviation industry, are closely related to the technical performance. The performance of the lubricating grease selected for the lubrication parts of the components in these systems directly affects the safety and reliability of the aircraft, an...
