Abstract
The utility model discloses a photochromic dimming heat-insulation film which comprises a stripping layer, a bonding layer, a first PET layer, a second PET layer, an anti-scratching layer and a functional film layer, wherein the functional film layer has a photochromic dimming function and is capable of blocking infrared rays and ultraviolet rays; the stripping layer, the bonding layer, the first PET layer, the functional film layer, the second PET layer and the anti-scratching layer are sequentially stacked from top to bottom. Therefore, through the functional film layer sandwiched between the first PET layer and the second PET layer, infrared rays and ultraviolet rays are absorbed by functional particles added to the functional film layer so as to achieve a heat-insulation effect; meanwhile, the visible light transmittance is adjusted according to the characteristic that the film is photochromic under the irradiation of the sunlight via the functional particles added to the functional film layer, thus achieving sun-shielding and heat-insulation effects; furthermore, the photochromic dimming heat-insulation film also has the characteristics of high light transmittance and good using performance, and can be widely applicable to the field of films for buildings, automobile windshields and the like.
Description
Technical field
Heat insulation, sun shading material art that the utility model relates to, refers in particular to a kind of photochromic light modulation thermal isolation film.
Background technology
Light modulation thermal isolation film is exactly a kind of heat insulation and overlay film shading performance that has, and it is generally applied in the fields such as building, automobile.Thermal insulation, sun-shade film is in the market made multilayer to close high heat insulating metal rete by vacuum evaporating or magnetron sputtering technique by metals such as aluminium, gold, copper, silver often, it is by surface protecting layer, plastic film substrate, hologram etch layer, metal deposition layer, pressure-sensitive adhesion layer and adherent layer are composited in sequence.
Above-mentioned existing thermal insulation, sun-shade membrane structure, though there is certain sunshade and heat insulation effect, really there is progressive, but in the time that being used, reality but finds still to have many deficiencies in himself structure and serviceability, cause existing Sunshade film in practical application, fail to reach best result of use and task performance, now its shortcoming is summarized as follows: 1) definition is not high, affects visual field comfortableness; 2) reflective higher, the height that is similar to minute surface is reflective, easily causes light pollution.Some product is reflective for reducing, and is mixed with coloring agent in the glue in film, easily weather stain; 3) can not there is along with the variation of sunlight intensity the change of light transmittance in existing thermal insulation, sun-shade film, thereby make the sunshade of current thermal insulation, sun-shade film and effect of heat insulation can not meet the diversified demand of the function of the market.
Utility model content
In view of this, the utility model is for the defect of prior art existence, and its main purpose is to provide a kind of photochromic light modulation thermal isolation film, and it can effectively solve sunshade and the limited problem of effect of heat insulation function of existing thermal insulation, sun-shade film.
For achieving the above object, the utility model adopts following technical scheme:
A kind of photochromic light modulation thermal isolation film, includes peel ply, adhered layer, the first pet layer, the second pet layer, scratch resistant layer and can photochromic light modulation also can stop infrared ray and ultraviolet functional film layer; This peel ply, adhered layer, the first pet layer, functional film layer, the second pet layer and scratch resistant layer are from lower to upper successively together with folded being located at.
As a kind of preferred version, described functional film layer is colored transparent or water white transparency material.
As a kind of preferred version, described functional film layer is PVB, EVA or acrylic acid crosslinked resin.
As a kind of preferred version, the thickness of described functional film layer is 30 μ m～100 μ m.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:
By sandwiched functional film layer between the first pet layer and the second pet layer, utilize the functional particles realization that is added on this functional film layer to reach effect of heat insulation to infrared ray and ultraviolet absorption; Meanwhile, utilize the functional particles that is added on this functional film layer to realize this film and can photochromic feature be adjusted by visible light transmissivity under solar light irradiation, reach further sunshade and effect of heat insulation.This product also has the feature of high transmission rate, and serviceability is better, can be widely used in the fields such as building pad pasting and automotive windshield, meets the diversified demand of the function of the market.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.
Brief description of the drawings
