Problems solved by technology

[0005] However, the two-color PVD coating method disclosed in the above-mentioned patent uses chemical agents to corrode the second layer of PVD coating and cannot corrode the first layer of PVD coating. Aluminum, tin, which also cannot obtain a variety of metallic colors, such as red and yellow, blue and green, etc., and it needs ink to be printed on the surface, which is not easy to handle complex workpieces

Embodiment 1

[0027] Example 1: A seamless ceramic white and gold faucet

[0028] 1) Spray the ceramic white high-gloss paint layer on the faucet first, and bake at 70°C for 30 minutes.

[0029] 2) Spray the workpiece treated in step 1) with a black peelable paint layer, and bake at 70°C for 20 minutes.

[0030] 3) The workpiece processed in step 2) is subjected to 3D laser laser patterning, and the black peelable paint layer on the surface is removed to expose the lower colored high-gloss paint layer.

[0031] 4) The workpiece treated in step 3) is subjected to PVD arc ion plating of golden titanium nitride, coating conditions: nitrogen gas 150Sccm, current 90A, coating time 3min, vacuum degree 0.1Pa.

[0032] 5) Remove the peelable paint layer on the surface of the workpiece processed in step 4) with 3M adhesive tape.

[0033] 6) The workpiece treated in step 5) is sprayed with a transparent varnish layer, and baked at 70°C for 50 minutes.

Embodiment 2

[0034] Example 2: A seamless sapphire blue and stainless steel shower head

[0035] 1) Spray the pure sapphire blue high-gloss paint layer on the shower head, bake at IR60°C for 5 minutes, and UV energy 800mj / cm 2 .

[0036] 2) The workpiece treated in step 1) is sprayed with a black peelable paint layer, baked at IR60°C for 5min, and UV energy is 1500mj / cm 2 .

[0037] 3) The workpiece processed in step 2) is subjected to 3D laser laser patterning, and the black peelable paint layer on the surface is removed to expose the lower colored high-gloss paint layer.

[0038] 4) The workpiece treated in step 3) is subjected to PVD arc ion plating of stainless steel colored zirconium nitride, coating conditions: nitrogen 50 sccm, argon 100 sccm, current 120A, coating time 2min, vacuum degree 0.2Pa.

[0039] 5) Remove the peelable paint layer on the surface of the workpiece processed in step 4) with 3M adhesive tape.

[0040] 6) The workpiece treated in step 5) is sprayed with a tr...

Abstract

The invention relates to a method for implementing seamless bicolor electroplating to plastic parts, relates to a surface processing technique for plastic parts, and provides a method for implementing seamless bicolor electroplating to plastic parts. Seamless double colors or two appearances can be formed on the surface of a plastic part by the method. The method includes: spraying the surface of the plastic part to form a colored high-gloss paint layer; spraying to form a black strippable paint layer; lasering to remove the black strippable paint layer from the surface of the plastic part so as to expose the colored high-gloss paint layer under; performing PVD (physical vapor deposition) to plate a metallic film; using an adhesive tape to remove the strippable paint layer on the surface; and spraying to form a transparent varnish layer so as to obtain the plastic part subjected to seamless bicolor electroplating.

Description

technical field [0001] The invention relates to a surface treatment process of plastic parts, especially a surface treatment process for obtaining two colors on the surface of a workpiece, and the joints of the two colors are smooth and continuous without joints, such as the combination of metallic color and ceramic white. Background technique [0002] With the development of society, people's pursuit of product appearance is getting higher and higher, and it tends to be diversified, and no longer satisfies a single color or basic principle. [0003] At present, non-ferrous electroplating processes include water electroplating or vacuum coating. Compared with water electroplating, vacuum coating has the advantages of no pollution and rich colors, and has replaced the traditional colored water electroplating process. However, in the production process of vacuum coating, only a certain monochrome effect can be produced on the appearance of the product, and the coating with tw...
