The invention discloses a multi-particle synergistic water-soluble titanium alloy hot rolling lubricant and a preparation method thereof, and belongs to the field of rolling lubrication. The lubricantcomprises the following main components: a phosphate, graphene, oxide nano-powder, polyvinylpyrrolidone and deionized water. The preparation method comprises the steps that firstly, the phosphate isadded to the deionized water, and a magnetic stirrer is used for stirring; and graphene aqueous dispersion is added to a formed solution in a mode of adding while stirring under the environment of 80DEG C, then polyvinylpyrrolidone is added, stirring is performed, then mixed liquid is cooled to 35 DEG C, then nanopowder is added, the mixture is stirred, and finally mixed liquid is subjected to ultrasonic processing, and the lubricant is obtained. A lubricant preparation scheme for titanium alloy hot rolling is provided, and the lubricant has good applicability and stability and excellent anti-friction and anti-wear properties, can maintain the lubrication performance for a long time during the rolling process, and is excellent in lubrication performance during the hot rolling process.
