Abstract
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.
Description
technical field [0001] The invention relates to the technical field of PVC baking varnish adhesive tapes, more specifically, the invention relates to a PVC baking varnish adhesive tape for metal baking varnish vehicles and a preparation method thereof. Background technique [0002] Adhesive tape is composed of base material and adhesive. Two or more unconnected objects are connected together by bonding. The surface is coated with a layer of adhesive. The earliest adhesive comes from animals and plants. In the ninth century, rubber was the main component of adhesives, but in modern times, various polymers are widely used. Adhesives can stick things because of the bonds formed between their own molecules and the molecules of the objects to be connected. Molecules are firmly bonded together, the composition of the adhesive, according to different brands, different types, there are various polymers, there are many types of tapes, PVC baking varnish tape is one of the many tapes,...
