Abstract
The utility model relates to a heat insulation film. The heat insulation film has a layer structure, is formed by compounding a plurality of layers of heat insulation films together, comprises a transparent film substrate layer, and is characterized in that a tin indium oxide film layer, a tin antimony oxide film layer, an aluminum zinc oxide film layer, a gold film layer and an environment-friendly glue layer are plated on the film substrate layer in sequence. Compared with the prior art, the heat insulation film perfectly fuses reflection-type and absorption-type heat insulation films, can obstruct sunray heat energy most comprehensively and widely, has a good heat insulation effect, and meets the requirement for high transparency of front windshield glass of an automobile.
Description
Technical field
The utility model relates to a kind of thermal isolation film, particularly a kind of energy-saving heat-insulating film that is applied to above windshield glass of automobile, the building glass etc.
Background technology
For reaching the purpose of heat insulation sun, also be energy-conservation simultaneously, reduce the purpose of use automobile or architectural refrigeration plant, means commonly used are pasted thermal insulation film at materials such as glass exactly.
Existing thermal insulation film mainly is divided into 2 kinds:
A kind of is the absorption-type thermal isolation film that is coated with the infrared ray heat absorbent in film basic unit.Its principle is can absorb the solar spectrum middle infrared (Mid-IR) when shining upon, and makes the IR heat energy that passes through reduce the heat insulation effect of playing.Usually this class is owing to be to use the chemical substance such as infrared absorbent, under solar light irradiation the effect of heat insulation decline very fast, generally will lose efficacy at 8 to 10 months.
Another kind is the reflection type thermal insulation film that is coated with the metal materials such as fine aluminium, silver, nickel, chromium at film substrate.Its principle is to utilize these metal materials that the reflectivity of light is reduced passing through of visible light heat energy, thereby reaches heat insulation effect.Usually this class is owing to use 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 light is seen through significantly reduce, therefore can't satisfy 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.
Also have, these 2 kinds of thermal isolation film all only possess separately to the heat-blocking action of sunray section single wave band at present, are difficult to sunray wave band is widely intercepted and reflects, and effect of heat insulation is not satisfactory, therefore has significant limitation.
The utility model content
Deficiency for the prior art existence, the purpose of this utility model has provided a kind of thermal insulation film, this kind thermal isolation film long service life, and light transmittance is higher, can be more comprehensively, widely intercept and sunlight reflection in the heat energy light-wave band, thereby have good effect of heat insulation.
The technical solution of the utility model is:
A kind of thermal insulation film, this thermal insulation film has layer structure, for the multilayer insulation rete is composited, comprise transparent film substrate layer, it is characterized in that: be coated with successively tin indium oxide rete, tin-antiomony oxide rete, aluminum zinc oxide rete, gold rete and environmental protection glue layer on the described film substrate layer.Described tin indium oxide rete is the ITO rete, and described tin-antiomony oxide rete is the ATO rete.Wherein ITO, ATO, aluminum zinc oxide, gold adopt nanometer technology, make its particle less, do not affect sight line.
The beneficial effects of the utility model are:
Tin indium oxide (ITO), to the infrared ray of 800-4000nm wave band intercept and reflection strong, can intercept in a large number the sunray heat energy of this wave band, and ultraviolet ray is also had good iris action.Tin-antiomony oxide (ATO), to the infrared ray of 780-2500nm wave band intercept and reflection strong, can intercept in a large number the sunray heat energy of this wave band.These 2 kinds of obstructs occupy the infrared ray of sunray 53% heat energy, and simultaneously, these materials itself have up to the light transmission more than 80% and reach the characteristic that did not lose efficacy in 20 years.
Aluminum zinc oxide and gold to the reflection of the luminous ray of 380-780nm wave band better, can intercept the sunray heat energy of this wave band in a large number.Aluminum zinc oxide has overcome the shortcoming of fine aluminium because of oxidized turning black and changing color, mixes the zinc of a certain amount of (about 10%) simultaneously in aluminium oxide, and chemical characteristic tends towards stability, thereby is difficult to oxidized again.The gold characteristic good, effect is lasting, plays good action to intercepting visible light heat energy
Compared with prior art, thermal insulation film of the present utility model is reflection-type and the perfect fusion of absorptive-type two kinds of thermal isolation film, can intercept the most comprehensive, widely sunray heat energy, effect of heat insulation is fine, has also satisfied the requirement of windshield glass of automobile high transmission rate simultaneously.

The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to accompanying drawing 1, specific embodiment of the utility model is proposed, as shown in the figure, a kind of thermal insulation film, this thermal insulation film has layer structure, for the multilayer insulation rete is composited, comprise transparent film substrate layer 1, comprise plating successively on the film substrate layer 1 being provided with tin indium oxide rete 2, tin-antiomony oxide rete 3, aluminum zinc oxide rete 4, gold rete 5 and environmental protection glue layer 6.Described tin indium oxide rete is the ITO rete, and described tin-antiomony oxide rete is the ATO rete.Wherein ITO, ATO, aluminum zinc oxide, gold adopt nanometer technology, make its particle less, do not affect sight line.
The above only is preferred embodiment of the present utility model; be not therefore to limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
