▎ 摘  要

NOVELTY - Composite plating layer comprises a silver layer, a silver-graphene layer and a surfactant molecular layer, which are sequentially deposited on a base material surface layer. The thickness of the silver layer is 5-20 microm, the thickness of the silver-graphene layer is 10-30 microm, and the thickness of the surfactant molecular layer is 2-10 nm.The surfactant molecular layer comprises surfactants containing mercapto and/or silicon, imidazoline amphoteric surfactants, sodium lauroyl sarcosinate and/or sodium lauryl sulfate. USE - Composite plating layer for high voltage isolating switch used in power plant and transformer substation electric system. Can also be used in electrical material. ADVANTAGE - The composite coating has excellent corrosion resistance and corrosion resistance, and can form a compact composite plating layer surface the metal base material insulating corrosive gas in the air, and improves the corrosion resistance base material. The plating solution obtained by preparation is stable and the management and maintenance are simple, it is environment-friendly, and has higher electrostatic repulsive force, which is more beneficial for the dispersion of the graphite. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method plating layer.
