Abstract
The utility model relates to a double-fluoride-film type solar packaging backboard, which comprises a first polyfluoroethylene film layer, a second polyfluoroethylene film layer and a polyethylene terephthalate film layer. The double-fluoride-film type solar packaging backboard is characterized in that the second polyfluoroethylene film layer is arranged between the first polyfluoroethylene film layer and the polyethylene terephthalate film layer, and the second polyfluoroethylene film layer and the polyethylene terephthalate film layer are adhered through glue. The first polyfluoroethylene film layer has excellent weather resistance, has no needle holes on the surface, can block ultraviolet rays in the atmosphere, and can protect parts in a solar module from being damaged by the ultraviolet rays and moisture. Carbon-oxygen keys are formed on the surfaces of fluoride-films of the second polyfluoroethylene film layer at high voltage through ozone oxidation, and thus the surface polarity is increased.
Description
Technical field
The utility model relates to the solar energy module encapsulation field, relates in particular to a kind of high weather-proofly, and easily the plain thin film solars of two fluorine of encapsulation encapsulate backboards.
Background technology
Backboard commonly used can be divided into TPT, TPE, full PET.Wherein T refers to polyvinyl fluoride (PVF) film of du pont company, and its commodity are called Tedlar, and PV2001 (first generation), PV2111 (second generation) difference is arranged.P refers to the poly terephthalic acid ethylene glycol film of biaxial tension.It is the PET film.E refers to ethylene-vinyl acetate resin EVA.
The polyvinyl fluoride of du pont company (PVF) film, it is low that model PV2001 (first generation) follows intensity to ethylene-vinyl acetate resin EVA, and there is macroscopic pin hole on model PV2111 (second generation) surface, and client has doubt on using.
The polyvinyl fluoride of du pont company (PVF) film, the intermolecular structure of model PV2001 (first generation) is comparatively loose, and after ethylene-vinyl acetate resin EVA heat-sealing, it follows the about 20-25N/cm of intensity, and long-time outdoor use has the doubt of peeling off; Its manufacturing of model PV2111 (second generation) is the wet type coating, PVF is resin-coated in peeling off rolling after the drying on the glass cloth, because of its glass cloth is to reuse, there is micro dust particle to attach on the glass cloth easily, cause model PV2111 (second generation) surface to have macroscopic pin hole to exist.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of model first generation polyvinyl fluoride thin film and ethylene-vinyl acetate resin of solving to follow the plain thin film solars of two fluorine of low problem of intensity and model second generation polyvinyl fluoride thin film open defect problem and encapsulate backboards.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of pair of plain thin film solar encapsulation of fluorine backboard, comprise the first polyvinyl fluoride thin film layer, the second polyvinyl fluoride thin film layer, poly terephthalic acid ethylene glycol thin layer, the described second polyvinyl fluoride thin film layer is located between the first polyvinyl fluoride thin film layer and the poly terephthalic acid ethylene glycol thin layer, is fitted and connected by sizing material between the second polyvinyl fluoride thin film layer and the poly terephthalic acid ethylene glycol thin layer.
According to another embodiment of the present utility model, a kind of pair of plain thin film solar encapsulation of fluorine backboard comprises that further described sizing material is an epoxy resin.
The utility model has solved the defective that exists in the background technology, its beneficial effect is: the described first polyvinyl fluoride thin film layer weather resistance excellence, the surface free of pinholes has good barrier for the atmosphere middle-ultraviolet lamp, can protect the solar energy module inner body not injured by ultraviolet ray and aqueous vapor; The second polyvinyl fluoride thin film layer is set up carbon-oxygen bond increase surface polarity through high voltage and ozone oxidation reaction in the plain film of fluorine surface.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, the first polyvinyl fluoride thin film layer, 2, the second polyvinyl fluoride thin film layer, 3, poly terephthalic acid ethylene glycol thin layer, 4, sizing material.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of pair of plain thin film solar encapsulation of fluorine backboard, comprise the first polyvinyl fluoride thin film layer 1, the second polyvinyl fluoride thin film layer 2, poly terephthalic acid ethylene glycol thin layer 3, the described second polyvinyl fluoride thin film layer 2 is located between the first polyvinyl fluoride thin film layer 1 and the poly terephthalic acid ethylene glycol thin layer 3, be fitted and connected by sizing material 4 between the second polyvinyl fluoride thin film layer 2 and the poly terephthalic acid ethylene glycol thin layer 3, described sizing material 4 can be epoxy resin.
The first polyvinyl fluoride thin film layer, 1 its weather resistance excellence, surperficial free of pinholes has good barrier for the atmosphere middle-ultraviolet lamp, can protect the solar energy module inner body not injured by ultraviolet ray and aqueous vapor; The second polyvinyl fluoride thin film layer 2 is at the fluoroplast film that contains vinyl polymerization, the surface physics oxidation processes, utilize the plain film of PVF itself to contain the vinyl of fluorine bond, setting up carbon-oxygen bond through the high voltage ozone oxidation reaction in the plain film of fluorine surface increases surface polarity.
Originally be to be with novel manufacturing process: with the plain film of fluorine two surfaces after too high voltages and ozone Oxidation Treatment, fit with the poly terephthalic acid ethylene glycol film that scribbles sizing material 4, obtain the plain film encapsulation of two fluorine backboard after the applying on two sides, reaching certain proportion in back plate surface formation carbon-to-oxygen ratio simultaneously can do then with ethylene-vinyl acetate copolymer.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
