[0003] At present, foreign countries have relatively mature antibacterial treatment on the surface of metal products, and the effect is relatively good. There are also many metal antibacterial materials developed and utilized, while domestic development and production in this area are relatively small, and many metal products with high antibacterial performance must be imported. Obtained, even though the country can meet the demand of some antibacterial metal products, there is a big gap between the production of many antibacterial metal products compared with foreign countries, such as: high production cost, not long-lasting antibacterial time, lack of excellent sterilization of various bacteria and fungi Effectiveness, the antibacterial materials used are toxic and unsafe, low heat resistance and wear resistance, and little prospect for promotion and application

Abstract
The invention discloses an antibacterial coating used for a surface of a metal product. The antibacterial coating comprises a bottom layer, an intermediate layer and a surface layer, wherein the bottom layer is a nickel plating layer; the intermediate layer is a chromium plating layer; the surface layer is a copper-containing antibacterial layer; special antibacterial powder materials are dispersed uniformly between the bottom layer and the intermediate layer. The antibacterial coating used for the surface of the metal product, disclosed by the invention, is reasonable in material use, environment-friendly, safe, heat resistant and wear resistant, has a great effect on sterilizing various bacteria, and is stable and everlasting in antibacterial performance, and wide in applicable scope.
Description
technical field [0001] The invention relates to a metal product, in particular to an antibacterial coating for the surface of the metal product, and belongs to the technical field of metal products. Background technique [0002] With the progress of society and the development of science and technology, metal products are more and more widely used in various fields of industry, agriculture and people's life, and at the same time, they have created more and more value for society. At present, metal products are facing many problems, among which the antibacterial problem is a problem that metal products must face and solve. Especially for metal products used in kitchen utensils, food and medical facilities, extremely high antibacterial requirements are put forward. In order to improve the antibacterial performance of metal products, people usually add metal antibacterial materials to the surface of metal products through coating. This kind of metal antibacterial materials can ...
