The invention discloses an antibacterial PVDC coating material and a preparation method and application thereof.The preparation method of the antibacterial PVDC coating material comprises the steps that MXene aqueous dispersion with the mass fraction being 0.1-10%, an emulsifier, an initiator and methyl acrylate are sequentially added into a reaction kettle, vinylidene chloride monomers are introduced after vacuumizing is conducted, then nitrogen is introduced to the normal pressure, heating polymerization reaction is conducted, and the antibacterial PVDC coating material is obtained. The PVDC emulsion with the antibacterial property is prepared, and the PVDC emulsion is the antibacterial PVDC coating material. Wherein the mass ratio of the MXene to the methyl acrylate is (0.02-0.1): 1, and the mass ratio of the vinylidene chloride monomer to the methyl acrylate is (8-10): 1. According to the invention, the excellent antibacterial activity of Mxene and PVDC are utilized to form a functional coating material,
