The invention relates to the technical field of zippers, in particular to an anti-oxidation treatment process for the surfaces of metal zippers (red metal, yellow metal and the like). The process comprises the following steps of: polishing arranged zippers (made of red metal, yellow metal and the like) in various models to remove burrs, cleaning by using metal cleaning agent, soaking in antirust aqueous solution for 1 to 2 minutes to ensure that an antirust protective layer is generated on the surfaces of zipper teeth, wherein the antirust aqueous solution is prepared by adding water into 1,2,3-benzotriazole; and sealing a lacquer adhesive layer on the surfaces of the zipper teeth and pullers to realize the function of double protection, wherein the lacquer adhesive is prepared by mixing LY-02A lacquer, an LY-03B hardening agent and a mixed solvent. Through various tests, the product can resist yeast washing water, dry cleaning, acids and alkalis, high temperature, oxidation and otherwashing water, and solves the long-term problem that the conventional metal zippers are easy to decolor, oxidize, discolor, stain and the like after the zippers are subjected to washing water or damped.
