NOVELTY - The utility model claims a graphene modified high anti-corrosion zinc-aluminium coating for automobile fastener, comprising a silver plating layer, dacroment plating layer, nickel plating layer, cadmium plating layer, zinc plating layer and graphene aqueous slurry layer. The dacromet plating layer and zinc plating layer or nickel plating layer of the utility model can effectively solve the problem of corrosion caused by the long-term exposure of the automobile fastener in the air; on a certain degree, it can prolong the service life of the fastener, prevent the automobile fastener from being corroded to cause the user to be in the driving process; the traffic accident is caused by the corrosion of the fastening piece; the ink alkene aqueous slurry layer not only can beautify the automobile fastener, but also can prevent the fastening piece fastener oxidation biting condition, so as to be convenient for the later use of the user, through the silver plating layer and cadmium plating layer can realize good connection between each plating layer.
