Abstract

The invention discloses a bio-based extreme pressure lubricant and a preparation method thereof. The preparation method comprises the following steps: step 1, mixing fatty acid, a compound containingterminal double bonds, a quaternary ammonium salt catalyst and hydroquinone, and reacting to obtain fatty acid containing terminal double bonds; step 2, carrying out polymerization reaction on the fatty acid containing the terminal double bond obtained in the step 1 and garlic oil in an inert organic solvent containing an initiator; and then evaporating under reduced pressure to remove the inert organic solvent to obtain a fatty acid-based extreme-pressure lubricating additive; and 3, dissolving the fatty acid-based extreme pressure lubricant additive obtained in the step 2 in vegetable oil toobtain the bio-based extreme pressure lubricant.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to a bio-based extreme pressure lubricant and a preparation method thereof. Background technique [0002] Lubricating oil is an indispensable part in the operation of machinery, which plays the role of reducing friction and wear, protecting machinery, cooling, cleaning, sealing, and prolonging service life. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oils have poor biodegradability, and some are ecologically toxic and pollute the environment. Biological base o...
