Description
Technical field
The present invention relates to the preparation method that a kind of part imitates mirror metal laminated film.
Background technology
Non-ferrous metal, nonmetal plate and non-ferrous metal and composite non-metal sheet material, add due to economizing on resources, being easy to
Work, cost are cheap, and the application in industry and life is more and more common.Particularly thin plate is more widely applied, automobile, ice
Case, washing machine, the furniture and room division board etc. of elevator wallboard and top grade have use.Above-mentioned sheet material is all to incite somebody to action earliest
It is processed into fixed shape, then is printed or sprayed to obtain appearance attractive in appearance, but this nonplanar printing and spray
The obtained appearance of painting processing is limited, technology is complicated.In recent years, in white goods industry, gradually rise in steel plate
Surface recombination plastic foil substitutes the sheet metal with special decoration appearance characteristics, can not only play protective action, also has dress
Decorations act on, and have good appearance.Regrettably the mode of plastic foil generally use ink printing produces multicolour
And pattern, cause visual fatigue unavoidably in the course of time, reduce the esthetic sentiment of people.
Number of patent application 200820034482 discloses a kind of VCM two-color clad steel plates, including steel plate and in steel plate overlying
Lid is bonded with composite film.Composite film is polyethylene terephthalate (PET)/two color printing layer/polyvinyl chloride (PVC)
The composite film of composition, covering bonding is provided with protection film layer on composite film, and back of the body enamelled coating is provided with steel plate layer back.In steel plate
Front is provided with PET/ two color printings layer/PVC composite films.User need not after product or semi-finished product is made again row spray painting or
Decoration, the back side of steel plate are provided with back of the body enamelled coating, steel plate can be protected not weathered during transport and use.The VCM is double-colored compound
Steel plate is applied to refrigerator door panel, has good wear resistance and resistance to soiling, makes refrigerator door panel integrated；So as to replace making in the past
With PVC profile and metallic plate splicing structure, simplify technique, reduce cost.But above-mentioned printed patterns are only with double-colored, simply
It is dull, it is impossible to meet the increasingly increased requirement attractive in appearance to product and domestic environment of people.
Number of patent application 200910034048 discloses a kind of double-layer PET printing complex plastic steel plate, in the front bonding of steel plate
There is PET film layer, gum layer is scribbled on PET film layer, it is also viscous in pattern printed layers covered with pattern printed layers on gum layer
True wire drawing PET film layer is connected to, back of the body enamelled coating is additionally provided with steel plate layer back.Surface recombination PET film layer, pattern printed layers in steel plate
With PET film layer, not only with environment-protecting and non-poisonous performance, and pattern and color can be changed as requested, and texture is more rich
It is full.The steel plate can be widely used for various decorations and household appliances.Patent 200910034048 is compared to patent
200820034482 have obvious technological progress, and it forms PET/two color printing layer/polyvinyl chloride
It is compound that composite film is improved to double-layer PET printing, but because its pattern is equally printed using ink, the visual effect of pattern is not enough waken up
Mesh is beautiful, thus the effect decorated is not still good enough.
Therefore, this area needs a kind of eye-catching new composite beautiful, contrast is strong, visual effect protrudes badly.
The content of the invention
The technical problems to be solved by the invention are the colors in order to overcome the pattern of existing VCM films not distinct beautiful enough
Color dullness, the defects of not strong enough and visual effect and decorative effect difference is contrasted, and provide a kind of imitative mirror metal of part and answer
Close the preparation method of film.Mirror metal laminated film is locally imitated made from the preparation method of the present invention, pattern has minute surface golden
The texture of category, and distinctness is beautiful, contrast is strong, visual effect protrudes, and possesses fairly individual attractive, decorative effect；Meanwhile
With good industrial value and application prospect, and this method is simple to operate, can be used in existing production technology, fits
For industrialized production.
Inventor produces in the application of all kinds of ornaments, clothes from gilding film and gained enlightenment at the beginning of research and development：Courageously contemplate
Aluminizing for vacuum plated aluminum film is processed into specific pattern or decorative pattern, then by its with other Film laminateds into VCM composite membranes, finally
Fitting production VCM clad steel plates, so as to which a kind of composite of the beautiful decorative pattern with simple metal texture be made.Set based on this
Think, inventor is by substantial amounts of experiment and constantly gropes, and finally finds, using specific materials processing technology, with closing spy
Fixed technological parameter and process conditions, a kind of unique and novel VCM clad steel plate ornament materials is finally given, so as to complete this
Invention.
