Abstract: A preparation method of a chelated lithium molybdate lubricant additive includes: adding kaolin and HDTMS into deionized water, performing magnetic stirring and ultrasonic treatment, then stirring to perform a reaction, and after the reaction is finished, filtering, washing and drying a reaction product to obtain alkylated kaolin; adding the alkylated kaolin and APTMS into deionized water, performing magnetic stirring and ultrasonic treatment, then stirring to perform a reaction, and after the reaction is finished, centrifuging, washing and drying a reaction product to obtain amino/alkylated kaolin; adding the amino/alkylated kaolin into a chelated lithium molybdate ionic liquid, stirring for a reaction, and after the reaction is finished, filtering, washing and drying a reaction product to obtain the chelated lithium molybdate lubricant additive. The prepared lubricant additive has good dispersibility in base oil, and performs well in friction reduction and anti-wear.
