Description
Technical field
The utility model relates to the imitative mirror metal laminated film in a kind of local.
Background technology
Non-ferrous metal, nonmetal plate and non-ferrous metal and composite non-metal sheet material, due to the processing that economizes on resources, is easy to, with low cost, the application in industry and life is more and more general.Particularly the application of thin plate is more extensive, and the furniture and room division board etc. of automobile, refrigerator, washing machine, elevator wallboard and top grade have use.Above-mentioned sheet material is all be processed into fixing shape the earliest, then carries out printing or spray to obtain appearance attractive in appearance, but the appearance that this nonplanar printing and spray process obtain is limited, technology is complicated.In recent years, at white goods industry, rise gradually and substitute the sheet metal with special decoration appearance characteristics at surface of steel plate composite plastic film, can not only protective action be played, also there is decoration function, there is good appearance.Regrettably plastic foil adopts the mode of ink printing to produce multicolour and pattern usually, causes visual fatigue unavoidably 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 plate, comprises steel plate and cover on steel plate being bonded with composite film.Composite film is the composite film that PETG (PET)/two color printing layer/polyvinyl chloride (PVC) forms, and composite film covers bondingly be provided with protective film, is provided with back of the body enamelled coating at steel plate layer back.PET/ two color printing layer/PVC composite film is provided with in steel plate front.User not to need after making product or semi-finished product row again to spray paint or decorate, and the back side of steel plate is provided with back of the body enamelled coating, and steel plate can be protected not weather in transport and use procedure.This VCM two-color clad steel plate is applied to refrigerator door panel, has good mar proof and resistance to soiling, makes refrigerator door panel integration; Thus replace using PVC profile and metallic plate splicing structure, Simplified flowsheet, reduces costs. in the pastBut above-mentioned printed patterns only adopts double-colored, simply dull, can not meet that people increase day by day to product and domestic environment requirement attractive in appearance.
Number of patent application 200910034048 discloses a kind of double-layer PET printing complex plastic steel plate, PET film layer is bonded with in the front of steel plate, PET film layer scribbles gum layer, gum layer is coated with pattern printed layers, pattern printed layers is also bonded with true wire drawing PET film layer, is also provided with back of the body enamelled coating at steel plate layer back.At the surface recombination PET film layer of steel plate, pattern printed layers and PET film layer, not only have environment-protecting asepsis performance, and pattern and color can change as requested, texture is more plentiful.This steel plate can be widely used in various decoration and household appliances.Patent 200910034048 has obvious technological progress compared to patent 200820034482, the composite film of PET/two color printing layer/polyvinyl chloride composition is improved to double-layer PET printing compound by it, but because its pattern adopts ink printing equally, the visual effect of pattern is eye-catching not beautiful, and the effect of thus decorating is still not good enough.
Therefore, this area needs a kind of eye-catching beautiful, contrast is strong, visual effect is outstanding new composite badly.
