Abstract

The invention relates to a method for processing surfaces coated with copper layer substrates, and provides a method for processing surfaces of composite antimicrobial coatings coated with copper layer substrates. The method has long time antibacterial and bacteriostatic effects and includes cleaning and activating substrate surfaces plated with acid copper, electroplating semi-bright nickel layers on the processed substrates, electroplating antibacterial nickel layers on the processed substrates, physical vapor deposition (PVD) is performed to the processed substrates to obtain multilayer antibacterial metal film layers.

Description

technical field [0001] The invention relates to a surface treatment method for a substrate coated with a copper layer, in particular to a surface treatment method for a composite antibacterial coating on a substrate coated with a copper layer. Background technique [0002] Antimicrobial chemicals are used in a wide variety of consumer products such as soaps, oral care products, deodorants, personal care products, first aid supplies, kitchen utensils, computer equipment, clothing, children's toys, caulks, and vacuum cleaners. In the above examples, the antibacterial agent can be easily included in the product by adding the antibacterial agent in a certain proportion. In recent years, there has been a growing trend to impart antimicrobial properties to metals and polymeric materials such as plastics. Vacuum sputtering silver plating on stainless steel plate or doping silver in stainless steel plate can make it have antibacterial effect. Furthermore, silver ions are widely us...
