Abstract
The invention discloses the flexible mirror film of a kind of solar light reflecting mirror; in multilayered film material composite structure; this mirror film is seen along in sunlight incident direction, is followed successively by transparent flexible Inorganic material carrier film, metal material reflective film, metal material protective film, Performance of Pressure Sensitive Adhesive agent film and pressure sensitive adhesive and peels off protective film.The preferred ultrathin flexible glass film of transparent flexible Inorganic material carrier film or graphene transparent film.Adopt the solar light reflecting mirror that this mirror film is made, both there is the high transmission performance to sunshine, resistance to ultraviolet radiation energy, do not feared the performance of tanning by the sun permanent weathering, there is again the characteristic of softness, ultra-thin, light weight, its make simple, convenient transportation, installation easily, working stability, long service life.Meanwhile, after transparent flexible inorganic material surface composite nano materials hydrophobic film or the self-cleaning protective film of uvioresistant, also can make to be placed in outdoor solar light reflecting mirror and there is self-cleaning function, not binding dust, resistance to greasy dirt, acid and alkali-resistance, UV resistant, easy to clean.
Description
Technical field
The present invention relates to sunshine reflection technology, refer to the flexible mirror film of a kind of solar light reflecting mirror particularly.
Background technology
At present, in mirror equipment, the catoptron based on glass is most widely used.Particularly in solar light-heat power-generation field; existing paraboloid trough type catoptron, hyperbolic paraboloid dish-style catoptron, spheric curvature dish-style catoptron and sphere micro-curvature settled date catoptron etc.; most employing hot bending becomes the glass carrier of certain curve form to make; its machining profile is: first sheet glass use mould hot bending to become the bend glass carrier of setting curvature; then bend glass carrier is cleaned up; then on bend glass carrier, plate one deck silver metal reflective film; plate one deck copper metal coating film again, finally apply one deck protective layer.
These catoptron advantages generally of tanning by the sun lower work for outdoor sunshine are that reflectivity is high, to the full spectral reflectivity of sunshine up to more than 98%.And, due to the potpourri that glass carrier is inorganic salts, the adhesion of locating between material molecule lattice is not by the impact of ultraviolet light, namely it is insensitive to the ultraviolet in sunshine, on glass carrier there is not the phenomenon of damaging by UV-irradiation in institute's silver plated metals reflective film yet, and therefore its weathering performance is good, ultraviolet light erosional competency is strong, working stability is reliable, normal service life is high.Practice shows, first is used for the glass solar light reflection mirror continuous working nearly 30 years (except shock damage) of slot type generating in outdoor.But the shortcoming that glass solar light reflection mirror exists is also fairly obvious: need mold hot roll forming, complex manufacturing technology; Installation and Debugging are wasted time and energy, and are affected by the external environment comparatively large in use procedure, cracky under the weather extremes such as blast, heavy rain, hail.
In order to solve the problem, application number be 200680052293.1 Chinese invention patent application Publication Specification propose a kind of ultraviolet-resistant silver of the improvement be used in solar mirror, its designing points uses the organic polymer polyester material film of sandwich construction to substitute above-mentioned sheet glass.Its film layer structure is from top to bottom mainly: be mixed with the acylate film (PMMA is commonly called as organic glass) of ultraviolet light absorber, adhesive phase, poly-to stupid dioctyl phthalate ethylene glycol membrane of lipoprotein (PET), silver metal film, copper metal film and pressure-sensitive adhesive mixture layer.
The advantage of above-mentioned improvement silver mirror is: PMMA film, PET film are all very soft, overlayed just can be formed on rigidity sheet material various complex-curved, the processing in enormous quantities of solar light reflecting mirror, manufacture, transport, installation, debugging is made all to become easily convenient, thus can cost of manufacture be saved.Its shortcoming mainly contains two: the first, the combination process more complicated of layer high molecule polyester material film.The second, in macromolecule organic polymer molecules, the chemical bond C=H between carbon hydrogen element is very sensitive to the ultraviolet light in solar spectrum, and the long-term UV-irradiation that is subject to easily causes this chemical bond to disconnect, and macro manifestations is the aging damage of macromolecule organic polymer.Although this silver mirror takes the measure of ultraviolet light, still can there is degradation and decomposition phenomenon, thus cause its reflectivity to decline to a great extent in long-term insolation under sunshine.Described in its instructions, this silver mirror is in weather resisteant test (about 5 times to the insolation intensity of natural daylight), and the reflectivity being equivalent to retain in the weather resisteant test of 9 years is only 90%.Going through sunshine insolation in nearly 30 years with traditional glass carrier catoptron also retains compared with the reflectivity up to 97%, also has sizable gap, causes significantly shorten its serviceable life.
How to make full use of above-mentioned two kinds of catoptrons advantage separately, and overcome above-mentioned two kinds of catoptrons shortcoming separately, be those skilled in the art's difficult problems urgently to be resolved hurrily always.
Summary of the invention
An object of the present invention will provide a kind of both had high sunlight reflectivity, excellent anti-uv-ray and anti-tanned by the sun weathering performance, have again soft frivolous, make easily, install and the flexible mirror film of solar light reflecting mirror of convenient transportation.
Two of object of the present invention the flexible mirror film of provided solar light reflecting mirror is also had be placed in for a long time outdoor not easily laying dust, easy cleaning, working stability, remains performance to sunshine high reflectance.
For achieving the above object; the flexible mirror film of solar light reflecting mirror designed by the present invention; in multilayered film material composite structure; its special character is: this flexible mirror film is seen along in sunlight incident direction, is followed successively by layer of transparent flexible inorganic material support film, layer of metal material reflects film, layer of metal material protection film, one deck Performance of Pressure Sensitive Adhesive agent film and one deck pressure sensitive adhesive and peels off protective film.
Further, described transparent flexible Inorganic material carrier film is ultrathin flexible glass film or graphene transparent film.Wherein:
