Abstract
A heat-insulated composite film comprises a superficial anti-abrasion layer, a pressure sensing adhesive layer, a heat-insulated layer, a coating layer and a bottom polyester layer, wherein the pressure sensing adhesive layer, the heat-insulated layer, the coating layer and the bottom polyester layer are sequentially distributed up to down and positioned below the anti-abrasion layer. The heat-insulated composite film has excellent light reflecting performance and good effects of heat insulation and heat preservation, can insulate more than 90 percent of the sun infrared rays, saves energy, and has the characteristics of air purification, environmental protection, low probability of breakage, long service life and the like.
Description
Technical field
The utility model relates to a kind of thermal isolation film technical field, particularly a kind of heat insulating compound film.
Background technology
Glass heat-proof adopts the methods such as coating film on glass or pad pasting conventionally, and Heat insulation type adhering film high comprehensive performance obtains applying comparatively widely.Current thermal insulation film is mainly divided into 2 kinds:
In a kind of Shi film basic unit, be coated with the absorption-type thermal isolation film of infrared ray heat absorbent.Its principle is can absorb solar spectrum middle infrared (Mid-IR) when shining upon, and makes the IR heat energy passing through reduce the heat insulation effect of playing.Conventionally this class is owing to being to use the chemical substances such as infrared absorbent, under solar light irradiation effect of heat insulation decline very fast, generally at 8 to 10 months, will lose efficacy.
Another kind is the reflection type thermal insulation film that is coated with the metal materials such as fine aluminium, silver, nickel, chromium on film substrate.Its principle is to utilize these metal materials to reduce passing through of visible ray heat energy to the reflectivity of light, thereby reaches heat insulation effect.Conventionally this class is owing to using the materials such as fine aluminium, silver, easily oxidation after being exposed to the sun of sunshine, so that blackout, inefficacy.In addition, after using the materials such as nickel, chromium, visible ray is seen through significantly and reduce, therefore cannot meet the requirement of the high printing opacities of glass such as automobile front windshield, these metal materials have highly reflective simultaneously, have also caused to a certain extent light pollution.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of heat insulating compound film, its long service life, light transmittance is higher, can intercept more comprehensively, widely and sunlight reflection in heat energy light-wave band, thereby there is good effect of heat insulation.
In order to realize above object, the present invention is achieved through the following technical solutions:
A heat insulating compound film, comprises the wearing layer on top layer, pressure sensing adhesive layer, thermal insulation layer, the polyester layer of coat and bottom.Wherein by wearing layer, be followed successively by pressure sensing adhesive layer downwards, thermal insulation layer, the polyester layer of coat and bottom.
Preferably, the number of plies of described thermal insulation layer is 2-5 layer.
Preferably, described thermal insulation layer consists of hole-layer foam and doubling layer.
Preferably, the thickness of described heat insulating compound film is 100-1000 micron.
Preferably, the polyester layer of described bottom is transparent polyester layer.
Preferably, described hole-layer foam is polyethylene foamed layer.
Preferably, the thickness of described hole-layer foam is 5-50 micron.
Preferably, the thickness of described coat is 20-50 micron.
Adopt such scheme, the utlity model has following beneficial effect:
Heat insulating compound film reflective function of the present utility model is excellent, and heat insulation and preservation effect is good, can intercept more than 90% solar infrared, saves the energy, and has concurrently and purify air, environmental protection, the feature such as cracky, long service life not.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model heat insulating compound film.
In figure 1, wearing layer, 2, pressure sensing adhesive layer, 3, thermal insulation layer, 4, coat, 5, polyester layer, 6, hole-layer foam, 7, doubling layer
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Figure 1 shows that the structural representation of the utility model heat insulating compound film.
A kind of heat insulating compound film shown in this figure comprises the wearing layer 1 on top layer, pressure sensing adhesive layer 2, thermal insulation layer 3, the polyester layer 5 of coat 4 and bottom.Wherein by wearing layer 1, be followed successively by pressure sensing adhesive layer 2 downwards, thermal insulation layer 3, the polyester layer 5 of coat 4 and bottom, the thickness of this heat insulating compound film is 100-1000 micron.
Wherein said wearing layer 1 contains alumina particulate.The pressure-sensing glue of said pressure sensing adhesive layer 2 is colloids that polyorganosiloxane resin forms in toluene solvant.The number of plies of said thermal insulation layer 3 can be 2-5 layer, and every layer forms by hole-layer foam 6 and doubling layer 7, and said hole-layer foam 6 can be polyethylene foamed layer.Said coat 4 is the coatings that formed by organic polymer, animal glue, starch, dextrin, haemocyanin, albumin, methylcellulose or polyvinyl alcohol.Said polyester layer 5 is formed by transparent polyester.
Claims (8)
