The invention discloses a PVC baking varnish adhesive tape for a metal baking varnish vehicle. The adhesive tape comprises an original film and glue, the glue is arranged at the bottom of the original film, the glue and the original film are bonded, the area of the bottom surface of the original film is matched with the area of the glue, and the thickness of the original film is greater than that of the glue. By adding a proper amount of antioxidant into the glue and the original film of the adhesive tape, the service life of the adhesive tape can be prolonged, the adhesive tape can be prevented from being oxidized and corroded, the stability of the original film of the adhesive tape can be enhanced by utilizing a liquid barium-zinc stabilizer and a powdery stone powder stabilizer in the original film, meanwhile, the heat resistance of the PVC stoving varnish adhesive tape is also enhanced, the adhesive tape can be used in a high-temperature environment, and the applicability of the adhesive tape is enhanced. Terpene resin, hydrogenated resin and liquid phenolic resin are added, the unwinding force of the adhesive tape can be improved, meanwhile, the diffusivity of glue is reduced, and after the adhesive tape is torn off from an external object, the residual glue on the object is less, and the adhesive tape is convenient to clean.
