Abstract

The invention discloses alkaline graphene zinc-iron alloy electroplating liquid, a preparation method and an electroplating technology. Each liter of the electroplating liquid comprises main salt including 80-100g of zinc chloride and 5-12g of ferrous sulfate, 200-250g of conducting salt namely ammonia chloride, 200-300ml of an ammonia solution, 20-100mg of graphene quantum dots, 25-40g of a buffering agent namely boric acid, 8-16g of a brightener namely benzotriazole, 1-2g of a reducing agent, 10-22g of a complexing agent, 3-5g of a coordination agent namely stannous pyrophosphate, 0.2-1g ofsodium dodecyl sulfate, 1-3g of alkalization tetra-isopropyl amine and the balance of water, wherein the temperature of the electroplating liquid is 20-55 DEG C, and the pH of the electroplating liquid is 9-14. According to an electroplated product obtained through the formula of the electroplating liquid disclosed by the invention, a graphene-zinc ferrum composite plating layer can be formed through a simple electrodeposition technology, the plating layer is 10-20 microns, and through a cupric sulphate maceration and corrosion test, the plating layer shows excellent corrosion resistance and has excellent combination properties.

Description

technical field [0001] The invention relates to an electroplating solution, a preparation method and an electroplating process, in particular to an alkaline graphene zinc-iron alloy electroplating solution, a preparation method and an electroplating process. Background technique [0002] In the field of surface technology, with the development of the times, the protection performance requirements of many products are more stringent, and single-metal plating can no longer meet the requirements, and the performance of alloy plating is better than that of single-metal plating. Since the zinc coating is a good protective layer for the steel substrate, the alloy coating in the field of protective electroplating is still based on zinc. For example, zinc-iron alloy electroplating, zinc-nickel alloy electroplating and zinc-cobalt alloy electroplating and other technologies are more and more widely used due to their excellent corrosion resistance. Among them, the properties of zinc-...
