Sterilizing and environment-friendly composite plating layer, preparation method thereof and sterilizing and environment-friendly product

Abstract

A sterilizing and environment-friendly composite plating layer, a preparation method therefor, and a sterilizing and environment-friendly product. The sterilizing and environment-friendly composite plating layer comprises: a semi-bright nickel layer, a high sulfur nickel layer, and an environment-friendly white chromium composite sterilizing layer; the semi-bright nickel layer is disposed on a substrate that has a sterilizing requirement; the high sulfur nickel layer is disposed on a surface of the side of the semi-bright nickel layer away from the substrate; the environment-friendly white chromium composite sterilizing layer is disposed on a surface of the side of the high sulfur nickel layer away from the substrate; the environment-friendly white chromium composite sterilizing layer has a nano-needle structure and is formed by a sterilizing ammonium salt-containing composite raw material; and the concentration of the sterilizing ammonium salt in the composite raw material is 50 g/L to 100 g/L.
