Description
Technical field
The present invention relates to a kind of parts to imitate mirror metal laminated film.
Background technology
Non-ferrous metal, nonmetal plate and non-ferrous metal and composite non-metal plank add due to economizing on resources, being easy to
Work, of low cost, the application in industry and life is more and more common.Especially thin plate is more widely applied, automobile, ice
Case, washing machine, elevator wallboard and high-grade furniture and room isolation board etc. have use.Above-mentioned plank is all to incite somebody to action earliest
It is processed into fixed shape, then is printed or sprayed with the beautiful appearance of acquisition, but this nonplanar printing and spray
The obtained appearance of painting processing is limited, technology is complicated.In recent years, it in white goods industry, gradually rises 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, inevitably cause visual fatigue in the course of time, reduces the esthetic sentiment of people.
Number of patent application 200820034482 discloses a kind of VCM two-color clad steel plates, including steel plate and covers on the steel plate
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 equipped with protection film layer on composite film, and back of the body enamelled coating is equipped at steel plate layer back.In steel plate
Front is equipped 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
The back side of decoration, steel plate is equipped with back of the body enamelled coating, and steel plate can be protected not weather 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, keeps refrigerator door panel integrated；To replace making in the past
With PVC profile and metallic plate splicing structure, simplifies technique, reduce cost.But above-mentioned printed patterns are only with double-colored, simply
Dullness cannot meet the increasingly increased requirement to product and domestic environment beauty 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, is coated with gum layer on PET film layer, pattern printed layers are covered on gum layer, it is also viscous in pattern printed layers
It is connected to true wire drawing PET film layer, back of the body enamelled coating is additionally provided at steel plate layer back.In the surface recombination PET film layer of steel plate, pattern printed layers
With PET film layer, not only there is environment-protecting and non-poisonous performance, but also pattern and color can be according to requiring to be changed, 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 apparent technological progress, by polyethylene terephthalate/two color printing layer/polyvinyl chloride composition
It is compound that composite film is improved to double-layer PET printing, but because its pattern equally uses ink to print, the visual effect of pattern is not enough waken up
Mesh is beautiful, thus the effect decorated is not still good enough.
Therefore, this field there is an urgent need for it is a kind of it is eye-catching it is beautiful, comparison is strong, visual effect new composite outstanding.
Invention content
The technical problem to be solved by the present invention is in order to overcome the pattern of existing VCM films not distinct beautiful enough, color
Color not strong and visual effect and decorative effect difference enough the defect of dull, comparison, and it is multiple to provide a kind of imitative mirror metal in part
Close film.Mirror metal laminated film is imitated in the part of the present invention, and pattern has the texture of mirror metal, and distinct beautiful, right
It is protruded than strong, visual effect, has fairly individual attractive, decorative effect；Meanwhile there is good industrial value and application
Foreground.
