Description
Technical field
The present invention relates to field of optical films, there is the optical thin film low-launch-rate to be shifted by radiation with reducing heat energy, and the fenestrated membrane has protectiveness anti-dazzle and electromagnetic interference shield function.
Background technology
With social development and the raising of people's quality of life, requirement higher is proposed to environmental quality, for example at home and office etc. needs that translucency is good, moderate temperature, therefore, the exterior wall of building largely uses glass, under irradiation by sunlight, amount of heat is entered within doors by radiating, and causes temperature significantly to raise.Glass freezes under cold environment, easily or the icing or frosting of frosting, particularly automotive glass can influence sight line.In order to reduce influence of the heat radiation to heating indoor, and solve the problems, such as that glass freezes or frosting in cold environments, people generally eliminate these influences using the windowpane with low transmitting.
The glass of so-called low transmitting refers to that the optics for allowing specific wavelength passes through the glass, it can be common that low transmitting glass allows that visible ray (wave-length coverage is 380~780nm) passes through, while the optics beyond high reflection visible ray, such as infrared ray.Due to this low transmitting glass to infrared ray etc. with reflectivity high, therefore, can improve building, the window of vehicle it is heat-insulated, the thermal energy radiation that outside can be reduced in hot weather passes through window, interior is heated, and under arctic weather, the air that can reduce interior passes through glass to external radiation by heat radiation, so as to keep indoor temperature constant, prevent glass from freezing in cold weather or frosting.On the other hand, the low transmitting composite membrane of this patent description has heating function, and the glass of frosting or icing can be electrically heated, and frost is eliminated with this.Therefore, using the glass of low transmitting, comfortable living environment can be effectively provided, improves capacity usage ratio.
Generally, people prepare the glass of low transmitting by the direct sputter on glass or the laminated film of the low transmitting of coating, are then directly arranged on window in glass pane form.If the low compound film rupture of transmitting, or corroded under natural environment and failed, then must be changed whole window, such replacing not only high cost, and also its color appearance is uncoordinated with surrounding glass.Based on this, people employ a kind of actual and more economical method, that is, use the flexible low transmitting laminated film that may adhere on glass.This low transmitting laminated film of flexibility is easy to use and changes, and production efficiency is high.
The low transmitting laminated film of this flexibility is mainly using metal level come infrared reflecting, but this metal is in use, contact with air, steam etc. and easily corroded, and flexible substrate is easily scratched damage, the properties of infrared reflection of the reduction laminated film.A kind of effective ways for preventing the low transmitting diaphragm failure are that film plating layer is affixed with glass, flexible PET substrate and air contact, to a certain extent obstruct laminated film and air, the contact of steam.However, this installation method can cause the film with reflection very high, cause the generation of dazzle.When apply make low emission layer on glass pane, automobile wind shield glass, large-scale outdoor electrical equipment surface when, due to the generation of dazzle, the dimness of vision can be caused.How while low transmitting laminated film performance is ensured, the generation of oxidation and the reduction dazzle of metal level is prevented, obtained further extensively using the problem to be solved in fenestrated membrane field as the low transmitting laminated film of flexibility.Patent of the present invention is intended addressing above mentioned problem from film layer structure design; i.e. in the face sputter infrared external reflection composite beds of flexible PET mono-; in the another side sputter antireflection layer of PET; the antireflection layer is a kind of protectiveness antireflection layer; with double action; completely cut off infrared reflecting layer and air contact, increase the hardness of PET to prevent scratch.
In addition to control infra-red radiation and reduction dazzle, in addition it is also necessary to electromagnetic radiation is controlled, particularly in sensitive military working environment, and on electronic display unit.To the control measure of electromagnetic radiation, it is typically with copper or other conductive materials is shielded, and for glass pane, these shielding measures can have a strong impact on the transmitance of light.Laminated film described in this patent, not only with low emission characteristics, with protectiveness antireflective function, and has electromagnetic action to a certain extent.
