The invention relates to the technical field of coating, in particular to a coating process of a waterproof antibacterial film layer, which adopts a vacuum coating process and comprises a coated workpiece, at least one base layer, an antibacterial layer A and an antibacterial layer B. The coating process comprises the following steps: firstly, putting the coated workpiece into a vacuum cavity of avacuum coating machine, closing a door and vacuumizing to reach a preset temperature; and performing ion bombardment with a cleaning effect on the surface of the coated workpiece, evaporating the base layers to the surface of the coated workpiece, evaporating the antibacterial layer A to the surface of the base layer, evaporating the antibacterial layer B to the surface of the antibacterial layerA if one base layer is used, and evaporating the antibacterial layer B to the surface of the base layer at the upper part after the other base layer is added on the surface of the antibacterial layerA to form the waterproof a
