NOVELTY - Silver/graphene composite plating solution comprises 3-80g/L silver nitrate, 30-400g/L potassium iodide, 6-300g/L Na2S2O3, 1-20g/L nitric acid, 0.1-10g/L dispersant, 0.1-10g/L adjuvant, 0.01-3g/L defoamer, 0.5-5g/L graphene flakes and water. USE - Silver/graphene composite plating solution. ADVANTAGE - The silver/graphene composite plating solution prevents the vulcanization of the silver layer, realizes the isolation of silver and harmful gases, and improves the vulcanization resistance of the composite coating, and sulfur resistance far exceeds the requirements of the navigation standard QJ485-198. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using silver/graphene composite plating solution, which involves pre-plating substrate with silver to obtain pre-plated silver substrate, electroplating pre-plated silver substrate obtained in silver/graphene composite plating solution to obtain silver/graphene composite plating layer.
