Abstract
The utility model discloses a heat-insulting film which is low in cost and not easy to oxidize. The heat-insulting film comprises a first PET (Poly Ethylene Terephthalate) layer, a metal ion layer, a second PET layer and a protective film layer, wherein one surface of the first PET layer is an attaching surface; the metal ion layer is sputtered on the attaching surface of the first PET layer; the second PET layer is bonded to the outer surface of the metal ion layer through an adhesive layer; and the protective film layer is bonded to the surface of the second PET layer corresponding to the adhesive layer.
Description
Technical field
The utility model relates to a kind of overlay film, refers to a kind of thermal isolation film especially.
Background technology
Thermal isolation film is exactly to have overlay film heat insulation, the sunshade performance, generally is applied in fields such as building, automobile.Present thermal isolation film has LOW_E, plated film etc., LOW_E film excellent heat insulation property and optical property, but this film cost is higher, and the easy oxidation of the metal ion in the LOW_E film, thereby the result of use of LOW_E and life-span are reduced.
The utility model content
Technical problem to be solved in the utility model is: the thermal isolation film that a kind of cost is low, be difficult for oxidation is provided.
For solving the problems of the technologies described above; the technical solution of the utility model is: a kind of thermal isolation film; comprise first pet layer, metal ion layer, second pet layer, protective film; one of them surface of this first pet layer is attaching surface; this metal ion layer sputter is on the attaching surface of first pet layer; this second pet layer is bonded in by tack coat on the outer surface of metal ion layer, and described protective film adheres on second pet layer and the tack coat facing surfaces.
As a kind of preferred scheme, described metal ion layer is single layer structure, and the metal ion in this metal ion layer is any in sodium ion, copper ion, the silver ion.
As a kind of preferred scheme, described metal ion layer comprises double layer of metal ion unit layer at least, and the species of metal ion in the adjacent metal ion unit layer is inequality.
As a kind of preferred scheme, described the 2nd PET goes up near on the surface of tack coat and also is provided with printed layers.
After having adopted technique scheme; effect of the present utility model is: because a kind of thermal isolation film; comprise first pet layer; the metal ion layer; second pet layer; protective film; one of them surface of this first pet layer is attaching surface; this metal ion layer sputter is on the attaching surface of first pet layer; this second pet layer is bonded on the outer surface of metal ion layer by tack coat; described protective film adheres on second pet layer and the tack coat facing surfaces; therefore; at first; the one PET film is as the attachment of metal ion layer; and second pet layer is bonded in the metal ion laminar surface by tack coat, plays the effect that sealing prevents the metal ion oxidation, pet layer light transmittance height; the metal ion layer can be optionally with the various heat energies in the sunlight; comprise infrared ray; ultraviolet ray and visible light heat energy reflect back, cooperate the absorption of color to sun heat radiation of pet layer again after, secondary outwards discharges again; take away a part of heat along with outdoor air flows, thereby effectively play heat insulation effect.In sum, the metal ion layer in this thermal isolation film is difficult for oxidized, and simple in structure, only needs two-layer pet layer and tack coat, and layer is simple in structure, and heat insulation sunshade filter ultraviolet ray is good, and cost is low.
Because described metal ion layer is single layer structure, the metal ion in this metal ion layer is any in sodium ion, copper ion, the silver ion again; Or described metal ion layer comprises double layer of metal ion unit layer at least, species of metal ion in the adjacent metal ion unit layer is inequality, like this, according to the metal ion difference of selecting and the number of plies difference of metal ion elementary layer, can give thermal isolation film different heat-insulating capabilities.
Owing to also be provided with printed layers near on the surface of tack coat on second pet layer, therefore, this printed layers can be given effects such as thermal isolation film marble grain, wood grain, frosted again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure cutaway view of the utility model embodiment;
In the accompanying drawing: 1. first pet layer; 2. metal ion layer; 3. tack coat; 4. second pet layer; 5. protective film.
The specific embodiment
Below by specific embodiment the utility model is described in further detail.
As shown in Figure 1,
A kind of thermal isolation film; comprise first pet layer 1, metal ion layer 2, second pet layer 4, protective film 5; one of them surface of this first pet layer 1 is attaching surface; these metal ion layer 2 sputters are on the attaching surface of first pet layer 1; this second pet layer 4 is bonded in by tack coat 3 on the outer surface of metal ion layer 2, and described protective film 5 adheres on second pet layer 4 and tack coat 3 facing surfaces.
Wherein, this metal ion layer 2 can be individual layer or sandwich construction, and wherein, during for single layer structure, the metal ion in the metal ion layer 2 is any in sodium ion, copper ion, the silver ion.The performance difference of the obstruct heat energy of each ion can give thermal isolation film different barriering effects.When described metal ion layer 2 was sandwich construction, described metal ion layer 2 comprised double layer of metal ion unit layer at least, and the species of metal ion in the adjacent metal ion unit layer is inequality.Equally, sandwich construction also can make the ability of the obstruct heat energy of thermal isolation film improve, and makes up between each metal ion elementary layer, makes the kind of thermal isolation film more abundanter.
Also be provided with printed layers near on the surface of tack coat 3 on described second pet layer.Utilize printing means can make thermal isolation film have different decorative patterns, texture, pattern, like this, it is on glass for indoor decorative effect to utilize this thermal isolation film to be fitted in, and is that other glass can't analogy, thereby improves the class of glass product.
Thickness between above-mentioned each layer of thermal isolation film requires to formulate according to client's difference.
It is emphasized that; though above-described embodiment has been done more detailed explanation to the utility model; but these explanations are just illustrative to the utility model; rather than to restriction of the present utility model; any substantial utility model that is no more than this utility model is created, and all drops on protection domain of the present utility model.
