Abstract
The invention discloses an EVA adhesive film for solar module packaging. The EVA adhesive film is characterized by being prepared by mixing an EVA copolymer and a crosslinking curing agent according to a certain proportion; a tackifier, an ultraviolet stabilizer, an ultraviolet absorber and an age resister are further mixed in the EVA adhesive film. By means of a back plate, the process of laying an EVA adhesive film on the back side of a battery piece can be omitted; besides, the back plate has higher ultraviolet absorption capacity compared with a traditional back plate, and yellowing of the back plate of a module and delaminating of the back plate and EVA can be reduced.
Description
Technical field
The present invention relates to solar components field, particularly solar components packaging EVA (vinyl-vinyl acetate copolymer) glued membrane and backboard.
Background technology
One of main appeal point in photovoltaic customer complaint: the backboard jaundice of assembly, backboard and EVA delamination.Can there is xanthochromia in some backboard, cause the molecular composition part of backsheet layer to be destroyed under the UV-irradiation of 300nm-380nm, and the overall performance of backboard declines, simultaneously the reflectance reduction of backboard, and the entirety affecting assembly exports.Backboard and EVA easily produce electrostatic, can be adsorbed on above it by wisp, cause the stripping strength of EVA and backboard to diminish, even produce delamination.Turn to be yellow very urgent with delamination problems so solve backboard.
Summary of the invention
The object of the invention is to for the problems of the prior art, a kind of solar components encapsulation material is provided, reduce the backboard jaundice of generation component, the phenomenon of backboard and EVA delamination.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of solar components packaging EVA adhesive film, is characterized in that, mixed by a certain percentage by ethylene-vinyl acetate copolymer and crosslinking and curing agent, tackifier, UV light stabilizing agent and antiager.
In described EVA adhesive film, crosslinking and curing agent, tackifier, UV light stabilizing agent and siccative addition is separately 0.05wt%-0.5wt%.
VA (vinyl acetate between to for plastic) content of the ethylene-vinyl acetate copolymer in described EVA adhesive film is 20mol% ~ 35mol%.
Described UV light stabilizing agent is two (2,2,6,6 tetramethyl--4 piperidyl) SA esters.
Described crosslinking and curing agent is tert-butyl hydroperoxide carbonic acid-2-ethylhexyl.
Described tackifier are γ-methacryloxypropyl trimethoxy silane.
Present invention also offers a kind of solar components backboard, it comprises above-mentioned EVA adhesive film, intermediate support and outer protective membrane, and middle support between EVA adhesive film and outer protective membrane, and is bonded into one with EVA adhesive film and outer protective membrane.
Described intermediate support is PET material, and described outer protective membrane is fluoropolymer membrane, and described fluoropolymer membrane is fluorinated ethylene propylene, polyvinylidene difluoride (PVDF), poly(vinylidene fluoride) or THV.
Use backboard of the present invention to save and lay EVA adhesive film at the cell piece back side, and this backboard has the ability of stronger uv-absorbing relative to conventional backing plate, the backboard jaundice of assembly can be reduced, the phenomenon of backboard and EVA delamination.
Accompanying drawing explanation
Fig. 1 is the structural representation of solar components backboard of the present invention.
Fig. 2 is the structural representation of solar components backboard of the present invention for solar components.
Embodiment
Provide present pre-ferred embodiments below in conjunction with accompanying drawing, the preparation method of this solar components packaging EVA adhesive film be described in detail:
Embodiment:
Be that the ethylene-vinyl acetate copolymer of 20mol% ~ 35mol% mixes with 0.05%-5% crosslinking and curing agent, 0.05%-0.5% tackifier, 0.05%-0.5% UV light stabilizing agent, 0.05%-0.5% siccative by VA (vinyl acetate between to for plastic) content, extrudate, through curtain coating, cooling, traction, coiling technique, obtains EVA adhesive film.
EVA adhesive film of the present invention is used for backboard preparation as shown in Figure 1; it comprises EVA adhesive film 2, intermediate support 6 and outer protective membrane 7; middle support 6 between EVA adhesive film 2 and outer protective membrane 7, and is bonded into one by backboard sizing agent with EVA adhesive film 2 and outer protective membrane 7.Intermediate support 6 in the present embodiment is PET material, and outer protective membrane 7 is fluorinated ethylene propylene, polyvinylidene difluoride (PVDF), poly(vinylidene fluoride) or THV.Between fluoropolymer membrane and PET and EVA adhesive film, apply backboard sizing agent, be glued together by the form rolled, namely obtain the desired novel backboard of the present invention.
Be the schematic diagram of backboard 4 of the present invention for solar components shown in Fig. 2, comprise the panel 1, EVA adhesive film 2, cell piece 3 and the backboard of the present invention 4 that stack gradually.This backboard is apart from outside normal backboard encapsulation ability, also can in traditional components lamination process, can save and lay EVA adhesive film at the cell piece back side, this backboard of direct use, and this backboard is owing to having ultraviolet cut-on filler, relative conventional backing plate has the ability of stronger uv-absorbing, reduces the backboard jaundice of assembly, the phenomenon of backboard and EVA delamination.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.
