Lithium-based lubricating grease and method for producing the same
By combining phenolic ester derivatives and lithium-based thickeners, the preparation process of lithium-based grease was optimized, solving the problems of oxidative stability and low-temperature fluidity of vegetable oil base oils. This resulted in the biodegradability and non-toxicity of high-performance lithium-based grease, and improved the overall performance of the grease.

AI Technical Summary
Existing lithium-based greases, when using vegetable oil as a base oil, suffer from insufficient oxidative stability and poor low-temperature fluidity, making it difficult to meet the modern industrial demand for biodegradability and non-toxicity.
Lithium-based greases are prepared by using phenolic ester derivatives as base oil components and through specific synthesis methods, including the synthesis of phenolic ester derivatives and their combined use with lithium-based thickeners, extreme pressure anti-wear agents, and metal deactivators. The saponification and dehydration processes are optimized to improve the grease's antioxidant properties, anti-wear properties, and low-temperature performance.
The prepared lithium-based grease exhibits excellent antioxidant, anti-wear, and anti-corrosion properties, meeting the requirements of modern industry for biodegradability and non-toxicity, and improving the service life and reliability of the grease.
