The invention relates to multifunctional lubricating grease and a preparation method thereof, and belongs to the technical field of lubricating grease. The multifunctional lubricating grease comprises the following components in percentage by weight: 12-18 wt% of a thickening agent, 6.5-9 wt% of a composite functional additive, 0.9-1.1 wt% of a dispersing aid, 0.3-0.5 wt% of a cleaning agent, 0.1-0.2 wt% of an antioxidant and the balance of base oil, according to the composite functional additive, dimercaptothiadiazole is used as a raw material, branched hydroxyl is introduced for modification through a butenediol click reaction, then esterification with boric acid is carried out, and finally action with amino silicon oil is carried out, so that boron-containing sulfur-nitrogen heterocyclic rings are introduced into a long chain of the amino silicon oil, and the composite functional additive has good thermal stability and thermal migration resistance; the prepared lubricating grease has ...
