Abstract

The utility model relates to a reflection film, particularly a sun reflection film for a window. The utility model uses a plastic film as a base material, an adhering layer is coated on a metal coating protective layer, and the adhering layer can product weak adhesiveness when meeting water, which is convenient for construction. Compared with the existing sun films of vehicles, the reflection film has the advantages of simple structure, low cost and no need of a stripping layer and can effectively reflect ultraviolet and infrared rays in sunshine. Simultaneously, visible light can also penetrate, a decorative layer can also be additionally arranged on the film, and the utility model can have decorative performance and is suitable for glass windows of various vehicles and houses.

Description

Reflection film

The utility model relates to a kind of reflective membrane, particularly a kind of window sun reflective membrane.

For preventing that the strong illumination width of cloth from penetrating, people have invented a kind of reflective membrane, and it is pasted on the glass pane of house or automobile, can pass through visible light again simultaneously effectively with the ultraviolet ray in the sunlight, infrared reflection.But this reflective membrane still comes with some shortcomings: it has six layers of structure, be respectively plastic basis material, the coat of metal, plastic basis material, pressure-sensitive adhesive layer, adherent layer and peel ply plastic basis material, it has the three-layer plastic base material, its cost height, anti-ultraviolet property is poor, six layers of structure more complicated, manufacturing procedure is many, the cost height, the counterdie of peeling off that its adherent layer and peel ply plastic basis material are formed promptly discards behind sticking construction, waste is big, and simultaneously, it adopts permanent adhesive-layer, when needs are changed, be difficult to remove from glass fully.

The purpose of this utility model be to provide a kind of simple in structure, cost is low and the reflective membrane of easy construction.

The purpose of this utility model realizes with following technical proposals: it adopts plastic foil to make base material, and evaporation layer of metal coating is coated with layer protective layer on it on the coat of metal, and the protection coat of metal is not oxidized, adhered layer a little less than being coated with one deck again on the protective layer.Protective layer and adhered layer are respectively esters of acrylic acid varnish and the weak adhesive of water-soluble acrylic ester class.Also can be coated with one deck look film or the decorative layer of printed patterns is arranged on plastic foil, this decorative layer or look film also can be coated between the coat of metal and the plastic foil, to strengthen the ornamental of reflective membrane.Plastic foil can be polyester or polypropylene or polyethylene or acetate fiber or polychloroethylene film; The coat of metal can be aluminium or zinc oxide or chromium vacuum-coating.

The utility model adopts four-layer structure, it is simple in structure, cost is low, easy construction, does not need peel ply, and it can reflect away ultraviolet ray and infrared ray in the sunlight effectively, simultaneously can see through visible light again, its adhered layer adopts the weak jelly of water-soluble acrylic ester class, and it can meet the weak adhesiveness of water generates, so that be pasted on glass, its adhesiveness is not almost nil when meeting water, when no longer needing this reflective membrane, monoblock is shut down easily, does not draw the glue phenomenon and can not produce with glass.

Accompanying drawing has provided an embodiment of the present utility model.

Fig. 1 is the utility model structural representation.

The utility model is described in further detail with reference to the accompanying drawings.

With reference to Fig. 1, this reflective membrane is made base material by polyethylene film 1, and its bottom surface evaporation one deck zinc oxide vacuum-coating 2 is at vacuum-coating 2 bottom surfaces coating one deck methacrylate protective layer 3, adhesive 4 a little less than protective layer 3 bottom surfaces are coated with one deck water-soluble acrylic ester class again.For strengthening the ornamental of reflective membrane, the dark brown pigment film 5 of coating one deck on polyethylene film 1, make reflective membrane form the outside and be seen as silver color, inner face is seen as dark brown double-colored solar film, also can on polyethylene film 1, be coated with the printed layers of the fenestrate floral pattern of one deck, make this reflective membrane form the outside and see it is silver color, inner face sees it is the pape-cut shaped solar film that printed patterns is arranged.

Claims

1, a kind of reflective membrane is made base material by plastic foil (1), and evaporation layer of metal coating on it is characterized in that: go up coating layer protective layer (3) at the coat of metal (2), go up the weak adhered layer (4) of coating one deck at protective layer (3) again.

2, according to the described reflective membrane of claim 1, it is characterized in that: protective layer (3) and adhered layer (4) are respectively esters of acrylic acid varnish and the weak adhesive of water-soluble acrylic ester class.

3, according to the described reflective membrane of claim 1, it is characterized in that: plastic foil (1) is gone up coating one deck look film or the decorative layer (5) of printed patterns is arranged.

4, according to the described reflective membrane of claim 3, it is characterized in that: decorative layer (5) or look film can be coated between the coat of metal (2) and the plastic foil (1).

5, according to claim 1 or 2 or 3 or 4 described reflective membranes, it is characterized in that: plastic foil (1) is polyester or polypropylene or polyethylene or acetate fiber or polychloroethylene film.

6, according to claim 1 or 2 or 3 or 4 described reflective membranes, it is characterized in that: the coat of metal (2) is aluminium or zinc oxide or chromium vacuum-coating.
