The invention relates to the technical field of grease preparation, especially to a preparation method of a low noise compound titanium-based grease. The method includes adding fatty acid, aromatic acid and a certain amount of base oil to a reaction kettle, heating the mixture to 90-180 DEG C to dissolve, introducing nitrogen gas to expel air, adding tetraisopropyl titanate and a certain amount of metatitanic acid, continuing reaction for 1-7 h, slowly heating the mixture to 200-250 DEG C and performing high temperature refining for 5-10 min, then adding a certain amount of base oil for cooling, adding a certain amount of distilled water and uniformly stirring when the system is cooled to room temperature, heating to 120 DEG C, grinding, and homogenizing to obtain the low noise compound titanium-based grease.
