Metal piece surface imitative copper plating technique

Abstract

The invention relates to a metal piece surface imitative copper plating technique which is characterized by comprising the following steps: 1) carrying out shot blasting treatment on the metal piece surface to remove surface burr and oil stains; 2) spraying a purpose-made primer on the treated substrate surface; 3) baking the primer-coated workpiece at 150-160 DEG C for 15-25 minutes to obtain a workpiece of which the primer dry film thickness is 20-30 mu m; 4) spraying a purpose-made imitative electroplating real copper finish paint on the primer dry film surface; and 5) baking the workpiece coated with the finish paint at 150-160 DEG C for 15-25 minutes to obtain the finish paint dry film of which the thickness is 10-15 mu m. The metal piece surface treatment method provided by the invention has the advantages of simple technical process, low energy consumption and no wastewater discharge in the overall process, and avoids polluting the surrounding environment. The raw materials are low in price and easy to purchase. The appearance and properties of the coating has the tactile sensation of the copper plating product. The coating has favorable corrosion resistance and excellent salt mist resistance.

Description

technical field [0001] The invention relates to a green process for imitating copper plating on the surface of metal parts. Background technique [0002] At present, the traditional metal parts copper plating process includes cyanide copper plating, sulfate copper plating, pyrophosphate copper plating and so on. Because the copper plating layer has a good anti-corrosion effect on metal parts and has a good decorative effect, it is widely used in the surface treatment of steel, alloys, etc. [0003] However, cyanide copper plating, sulfate copper plating, pyrophosphate copper plating and other processes volatilize metal salt aerosols, which are harmful to human health and consume high energy. Moreover, the acid-base pollution and heavy metal pollution in the acid-base cleaning process in the traditional copper plating process cannot be ignored. The National Twelfth Five-Year Plan focuses on environmental pollution control, energy conservation and emission reduction as a key...

[0003] However, cyanide copper plating, sulfate copper plating, pyrophosphate copper plating and other processes volatilize metal salt aerosols, which are harmful to human health and consume high energy.

In addition, the acid-base pollution and heavy metal pollution in the acid-base cleaning process in the traditional copper plating process cannot be ignored.
