The electroplating process is developed to the present, is an important processing technology at present, and has a great proportion in the purposes of protection, decoration and the like. In particular, functional electroplating techniques are widely used in the fields of electronic industry, communication, military industry, aerospace, and the like. Although the application of electroplating is very wide, electroplating is one of three polluted industries, and brings great harm to human health.
With the improvement of the requirement of environmental protection, various imitation electroplating technologies are developed in recent years, such as an imitation electroplating processing technology for the surface of a hardware substrate, which sequentially comprises the following steps: spraying a primer, namely uniformly spraying a UV primer on the surface of the substrate and curing the UV primer to form a film; vacuum coating, namely placing the base material sprayed with the primer in a vacuum environment, and uniformly covering a coating layer on the base material in a distillation or sputtering mode; spraying finish paint, namely uniformly spraying high-temperature bright paint on the coating layer; coloring, namely completely soaking the base material in the coloring agent to color the surface of the base material. Although the metal layer imitating electroplating can be obtained, the process comprises vacuum coating, spraying two layers of finish paint and dip dyeing for coloring, the process is complex, the processing cost is high, the paint film layer is not wear-resistant, and the coloring agent used for coloring is toxic organic matter, which can cause certain harm to human body and environment. And the existing product can not block water vapor, so that the corrosion resistance of the product is poor, and the service life of the product is short.

s2, spraying UV paint on the cleaned substrate in the step S1 to form a UV primer layer, so that the bonding force between the substrate bottom layer and the plating layer is enhanced;
s3, sending the base material processed in the step S2 into a PVD furnace chamber for glow processing, and then carrying out PVD metal coating to form a PVD metal coating;
the PVD metal coating comprises a sputtering silicon target and an alloy target to form gradient silicon dioxide and a metal film on the surface of a base material, wherein the alloy target comprises CrSi, TiSi and NiCrSi, and a composite coating is carried out;
the technological conditions for PVD metal coating are radio frequency sputtering, the technological parameters are 10-3-1Pa of air pressure, 400-600V of voltage, 0.08-0.16A of current, 3-8Pa of argon pressure and 40-60mm of target base spacing, the oxygen content is increased at the rate of 20-30SCCM after deposition is carried out for 1-2min, and the deposition is continued for 2-5 min;
s4, heating the mixture containing the MMA monomer to 70-80 ℃ through vacuum heating equipment, and pushing the mixture steam into a PVD furnace chamber by using argon;

Namely, the monomer heated to 70-80 ℃ is introduced from the outside of the furnace immediately after the substrate is plated with the PVD metal film. The monomer is used for rapidly depositing a transparent polymer film on the PVD metal film under the action of plasma in a furnace. The polymer film has high activity and good bonding force with PVD film. The film is compact and flexible, and has good ductility, so the film has a buffer protection effect. The organic polymer film plays a role in avoiding the occurrence of crack in the PVD metal layer under the action of an improper external force. And because the polymer film has good transparency, the appearance and the glossiness of the metal layer are not influenced.

Product performance testing
Performing a cold-hot impact cycle test according to the method of ASME A112.18.1-2005; NSS corrosion resistance test according to ASTM B368-09; the anti-boiling test was performed according to ASTM D870-02, except that the temperature was raised to 80 ℃ and the boiling time was extended to 3 hours; referring to the method of ASTM D3580, but changing the parameters into rated displacement of 5 cm, vibration frequency of 10Hz, rated load of 1 kg, vibrating back and forth 100 times to perform vibration friction test (namely vibrating 100 times and then performing 8 times of cold and hot shock cycle test); the sheet was tested for flexural cracking according to ASTM D430; the paint and plate bonding force test (i.e. bending 200 times and then testing the water vapor transmission rate) was performed according to ASTM D3359, and the test results are shown in Table 1.
The quality requirement is as follows: (1) the hot and cold shock is circulated for 8 times, and no interlayer separation and bubbling are caused; (2) boiling with 80 deg.C hot water for more than 1 hr to obtain a product with no abnormal appearance; (3) through an anti-corrosion test of Neutral Salt Spray (NSS) for more than 96h, the surface has no corrosion points, no bubble separation layer, no coating film falling and other abnormalities; (4) and (3) detecting the water vapor transmission rate and the permeability of the test piece after the test piece passes through 200 times of bending tests, wherein the detection result is not more than 0.5 g/M2 x 24 hr.
The test results are shown in table 1:
TABLE 1 test results
The product performance test results in table 1 show that examples 1 to 5 all have good corrosion resistance and wear resistance, and can block water vapor and prolong the service life of the product.
As can be seen from example 1 and comparative example 1, the bonding force of the PVD metal plating layer can be enhanced by coating the UV primer layer. As can be seen from the examples 1 and the comparative examples 2 to 4, the PVD metal coating comprises a sputtering silicon target and an alloy target to form gradient silica and a metal film on the surface of the substrate, wherein the alloy target comprises CrSi, TiSi and NiCrSi, which can enable MMA monomers to generate polymerization reaction on the surface of the substrate to form an organic film similar to PMMA, and the organic film can form good adhesion with the PVD metal coating, ensure that the product can block water vapor, and can avoid the abnormal condition that the PVD metal layer cracks under the action of improper external force. As can be seen from example 1 and comparative example 5, the mixture containing MMA monomer is pushed into the PVD chamber by argon gas, so that MMA monomer is uniformly dispersed and polymerization reaction occurs on the PVD metal coating, and a uniform and transparent organic film is formed. It is clear from example 1 and comparative example 6 that the use of PMMA polymers directly on PVD metallization does not result in good adhesion.
The invention adopts the PVD coating technology, the appearance with the imitation electroplating effect can be obtained, and the monomer coating on the outermost surface is a transparent layer, so that the appearance texture of the product is not influenced; and the water vapor is blocked to improve the corrosion resistance, so that the traditional water-electroplating raw materials with heavy pollution such as high-concentration acid-base and chromic acid are replaced, and the problems of wastewater treatment and discharge are avoided.
The above additional technical features can be freely combined and used in superposition by those skilled in the art without conflict.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes in the features and embodiments, or equivalent substitutions may be made therein by those skilled in the art without departing from the spirit and scope of the invention.
