Abstract
The invention discloses a surface treatment double-color pattern deplating process (PPVD). The process comprises the following steps that: after being electroplated, a glass surface, a ceramic surface and the like of a plastic shell is sprayed or screen-printed with a photosensitive ink; after film exposure, alkaline solvent development, acid solvent etching, alkaline solvent film stripping and pure water washing, a pattern with metallic surface and high-precision mirror surface effect is formed; a UV or PU middle paint is sprayed on the surface; after the surface is electroplated, a photosensitive ink is sprayed or screen-printed on the surface; after film exposure, alkaline solvent development, acid solvent etching, alkaline solvent film stripping and pure water washing, a metallic surface is formed; and a double-color plating effect is finally formed. According to the invention, an exquisite pattern effect can be realized on the plating surface, the pattern is realized by vacuum film exposure, and the accuracy can reach nanoscale. The plating has two colors so that the product is more beautiful and more spaces are provided for the product design.
Description
Technical field
The present invention relates to plastic shell, glass, surface treatments such as pottery relate in particular to the surface treatment bicolorable graph line withdrawal plating (PPVD) of electronic product plastic shell.
Background technology
Surface treatment is the artificial process that forms one deck top layer different with machinery, physics and the chemical property of matrix on substrate material surface.The surface-treated purpose is to satisfy the corrosion resistance of product, wearability, decoration or other features requirements.For metal casting, we surface treatment method relatively commonly used are, mechanical grinding, chemical treatment, surface heat is handled, sprayed surface, surface treatment exactly to surface of the work clean, cleaning, deburring, degreasing, descale etc.At present, close plastic cement process for treating surface has:
1). electroplate.(shortcoming: effect is single, can't present pattern)
2). the radium carving.(shortcoming: pattern is coarse, and is not meticulous)
3). silk-screen, bat printing (shortcoming: pattern does not have metal-like, no mirror effect).
Summary of the invention
The objective of the invention is in order to overcome disadvantages of background technology; And the surface treatment that a kind of plastic shell is provided reaches electroplated metal texture and mirror effect simultaneously; And radium carving inaccessible precision of institute and smooth pattern effect, and the surface treatment bicolorable graph line withdrawal plating (PPVD) of two kinds of colors can appear in electrodeposited coating simultaneously.
To achieve these goals, the technical scheme of the present invention's employing is:
Surface treatment bicolorable graph line withdrawal plating (PPVD) may further comprise the steps:
1), and the material surface evaporated plating or sputter plating at material surface coated UV priming paint;
2) spraying or silk-screen photosensitive-ink;
3) with the material surface of film placement spraying or photosensitive-ink, locate, and carry out the vacuum exposure;
4) placing basic solvent to soak in material develops;
5) material after developing with the clear water cleaning and dipping and carry out acid flux material and soak etching;
6) clean the material after the etching with clear water and carry out basic solvent and move back film;
7) pure water cleans, the baking box baking, stoving time 10-30 minute, to water examine do till;
8) lacquer and UV priming paint and ultrasonic waves for cleaning material among lacquer or the PU in the coating UV successively;
9) again the material surface is evaporated plating or sputter plating successively; Spraying or silk-screen photosensitive-ink; Film exposure; Basic solvent develops; Clear water cleans; The acid flux material etching; Clear water cleans; Basic solvent moves back film; The baking box baking; Coat with lacquer among the lacquer PU in the coating UV, UV finish paint or rubberbase paint draw finished product.
Further, said material is plastic shell or glass or pottery; Thickness 10-20um during said primer, temperature 45 to 60 degree, stoving time 3-5 minute, UV energy 700-800 joule.
Further, said plating can be evaporation plating or sputter plating; Said evaporation plating is with the plating material, and indium, tin, aluminium etc. place the evaporation source in the vacuum chamber, under high vacuum condition, makes its evaporation through the evaporation source heating, is condensed on the plastic cement surface, forms metal film; Said sputter plating be target under high vacuum condition, collide target material surface through glow discharge, make the sputter of target material surface particle, be deposited on and form metal film on the material.
Further, thickness 5-10um when said spraying or silk-screen photosensitive-ink, temperature 60-70 degree, stoving time 10-20 minute.
Further, soak time 30-40 second when said basic solvent develops, bubbling 5-10 second.
Further, soaked 30 seconds-40 seconds during said acid flux material etching.
Further, paint film thickness 10-20um in when lacquer in the said coating UV, temperature 55 to 65 degree, stoving time 3-5 minute, UV energy 700-900 joule; Paint film thickness 10-20um in when coating with lacquer among the said coating PU, temperature 60-80 degree, stoving time 20-30 minute.
Further, finish paint thickness 10-15um during said coating UV finish paint, temperature 45 to 65 degree, stoving time 3-5 minute, UV energy 800-1200 joule; Paint film thickness 40-50um during said coating rubberbase paint, temperature 70-80 degree, stoving time 30 minutes.
The invention has the beneficial effects as follows at plastic shell, glass, behind the electroplating surfaces such as pottery, spraying or silk-screen photosensitive-ink; Through film exposure, basic solvent develops, the acid flux material etching; Basic solvent moves back film, and pure water cleans the back and forms surface metal texture, the high-precision pattern of mirror effect.Spray again among UV or the PU and coat with lacquer, behind the electroplating surface, spraying or silk-screen photosensitive-ink, through film exposure, basic solvent develops, the acid flux material etching, basic solvent moves back film, and pure water cleans the back and forms surface metal texture, forms double-colored coating effect at last.The present invention can realize exquisite pattern effect at coating surface, and pattern realizes that through the exposure of the film vacuum accuracy can reach nanoscale.Coating has two kinds of colors, makes product more attractive in appearance, to product design more spaces is provided.
