Problems solved by technology

[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.

Embodiment Construction

[0027] Below in conjunction with embodiment the present invention is described in further detail.

[0028] Taking the cast steel workpiece as an example to illustrate the imitation copper plating process on the surface of metal parts, it includes the following steps:

[0029] 1) Shot blasting is performed on the surface of the cast steel workpiece to remove burrs and oil stains on the surface. Shot blasting is a conventional method.

[0030] 2) Spray a layer of primer on the treated substrate surface.

[0031] The primer includes a primer composition and a first diluent. Wherein primer composition comprises following quality composition:

[0032]

[0033] The leveling agent can be selected from conventional leveling agents in the prior art as required.

[0034] The mass composition of the first diluent is:

[0035]

[0036] The mixing ratio of the primer composition and the first thinner is 1:0.5-0.6, and the viscosity of the paint is adjusted to 15S by using a Tu 2...

Abstract

The invention relates to an imitation copper plating process on the surface of metal parts, which is characterized in that it comprises the following steps: 1) carrying out shot blasting treatment on the surface of metal parts to remove burrs and oil stains on the surface; 2) spraying a 3) Bake the primer-coated workpiece at 150-160°C for 15-25 minutes to obtain a workpiece with a primer dry film thickness of 20-30μm; 5) Bake the coated workpiece at 150-160° C. for 15-25 minutes to obtain a dry film thickness of 10-15 μm. The metal parts surface treatment method provided by the present invention has simple technological process, low energy consumption, no waste water discharge in the whole process, and avoids pollution to the surrounding environment; moreover, the price of raw materials is low, easy to purchase, and the appearance and performance of the coating are excellent The texture of electroplated copper products has good corrosion resistance and excellent salt spray performance.

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...
