Abstract
The utility model discloses a double fluororesin thin-film-type solar energy packaging rear panel which includes a protective layer on the surface, a polyvinylidene fluoride thin layer under the protective layer, a polyethylene terephthalate glycol thin layer under the polyvinylidene fluoride thin layer, and a polyvinyl fluoride layer under the polyethylene terephthalate glycol thin layer. The two adjacent layers of the polyvinylidene fluoride thin layer, the polyethylene terephthalate glycol thin layer and the polyvinyl fluoride layer are stick to each other through an adhesive. The protective layer is 2-hydroxy-4-methoxybenzophenone thin layer, and the adhesive is unsaturated polyester. The adhesive strength between each layer of the real penal is enhanced through the unsaturated polyester resin adhesive, thus the ultraviolet radiation in the air can be withstood by the protective layer effectively, the corrosion to the rear penal is reduced, and the service life of the rear penal is prolonged.
Description
Technical field
The utility model relates to a kind of optical cement material membrane, is specifically related to a kind of for LCD computer, the two fluorine resin film type solar energy packaging back boards of liquid crystal mobile phone.
Background technology
Backboard commonly used can be divided into TPT, TPE, full PET.Wherein T refers to poly-fluorine ethylene film, and P refers to the polyethylene terephthalate film, E the refers to second rare resin EVA of rare-acetic acid second.Poly-fluorine ethylene film production process is to peel off rolling after the slaking on fluororesin-coated and the glass-fiber-fabric, because of its glass-fiber-fabric for reusing, easily have on dust particale adhesion and the glass-fiber-fabric, cause the surface to have macroscopic pin hole to exist, client has doubt on using, because poly-fluorine ethylene film is that rolling after the slaking on fluororesin-coated and the glass-fiber-fabric is formed, comparatively loose in intermolecular structure, long-time outdoor use has the doubt of peeling off.
The utility model content
The purpose of this utility model be to provide a kind of adhesion strength high, protect, two fluorine resin film type solar energy packaging back boards of long service life.
The technical solution of the utility model is; a kind of pair of fluorine resin film type solar energy packaging back board; the protective layer that comprises the top layer; the polyvinylidene difluoride film layer of protective layer below; the polyvinyl fluoride layer of the polyethylene terephthalate thin layer of polyvinylidene difluoride film layer below and polyethylene terephthalate thin layer below; described polyvinylidene difluoride film layer; be pasted together by adhesive between polyethylene terephthalate thin layer and the polyvinyl fluoride layer adjacent two layers; described protective layer is the ESCALOL 567 thin layer, and described adhesive is unsaturated polyester (UP).
In preferred embodiment of the utility model, the thickness of described protective layer is 20-45um.
In preferred embodiment of the utility model, the thickness of described polyvinylidene difluoride film layer is 35-60um.
In preferred embodiment of the utility model, the thickness of described polyethylene terephthalate thin layer is 25-50um.
In preferred embodiment of the utility model, the thickness of described polyvinyl fluoride layer is 45-75um.
In preferred embodiment of the utility model, the thickness of described adhesive is 15-30um.
Described in the utility model is a kind of pair of fluorine resin film type solar energy packaging back board, increase the adhesive strength of each layer of backboard by the unsaturated-resin adhesive, overcoat can effectively be kept out airborne ultraviolet radiation, reduces the erosion to backboard, increases the service life of backboard.
Description of drawings
Fig. 1 is the structural representation in two fluorine resin film type solar energy packaging back board one preferred embodiments of the utility model;
Each mark is as follows in the accompanying drawing: 1, protective layer, 2, the polyvinylidene difluoride film layer, 3, the polyethylene terephthalate thin layer, 4, the polyvinyl fluoride layer, 5, adhesive.
The specific embodiment
The below is described in detail preferred embodiment of the present utility model, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Described in the utility model is a kind of pair of fluorine resin film type solar energy packaging back board; referring to shown in Figure 1; the protective layer 1 that comprises the top layer; the polyvinylidene difluoride film layer 2 of protective layer 1 below; the polyvinyl fluoride layer 4 of the polyethylene terephthalate thin layer 3 of polyvinylidene difluoride film layer 2 below and polyethylene terephthalate thin layer 3 belows; described polyvinylidene difluoride film layer 2; be pasted together by adhesive 5 between polyethylene terephthalate thin layer 3 and polyvinyl fluoride layer 4 adjacent two layers; described protective layer 1 is the ESCALOL 567 thin layer, and described adhesive 5 is unsaturated polyester (UP).
Further, the thickness of described protective layer 1 is 20-45um.
Further, the thickness of described polyvinylidene difluoride film layer 2 is 35-60um.
Further, the thickness of described polyethylene terephthalate thin layer 3 is 25-50um.
Further, the thickness of described polyvinyl fluoride layer 4 is 45-75um.
Further, the thickness of described adhesive 5 is 15-30um.
At first at polyvinylidene difluoride film layer 2 surperficial armor coated 12-hydroxyl-4-methoxy benzophenone thin layer; then carry out hot-pressing processing; the semi-finished product that obtain are being carried out hot pressing applying processing formation integrative-structure with polyethylene terephthalate thin layer 3, polyvinyl fluoride layer 4; follow processing with ethylene-vinyl acetate copolymer more afterwards, obtain at last finishing product.
Described in the utility model is a kind of pair of fluorine resin film type solar energy packaging back board, increase the adhesive strength of each layer of backboard by the unsaturated-resin adhesive, overcoat can effectively be kept out airborne ultraviolet radiation, reduces the erosion to backboard, increases the service life of backboard.
The above only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
