Technical field
The utility model relates to technical field of solar, relates in particular to a kind of solar cell module back veneer.
Background technology
Solar module be a kind of be the equipment of electric energy with conversion of solar energy, receiving much concern aspect the utilization rate of natural resources and the ecological protection, have safety non-pollution, inexhaustible advantage, therefore obtained using widely.
General solar module all is with ethylene-vinyl acetate copolymer (EVA) solar battery sheet to be encapsulated between the transparent glass and backboard, but the cohesion of some backboard and EVA is not strong, cause the backboard delamination, corresponding shortening in the useful life of solar module.The used in the market PET of Mitsubishi combines with EVA, and its peel strength is less than 4N, and unfailing performance is lower, and therefore the needs solar module that a kind of peel strength is big, unfailing performance is high increases its useful life with adaption demand.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome problems such as existing solar module peel strength is little, unfailing performance is low, provide a kind of solar cell module back veneer.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of solar cell module back veneer, have toughened glass layer, EVA, solar cell layer, EVA and backsheet layer, have additional high temperature between EVA and the backsheet layer and cohere polyester layer, described toughened glass layer, EVA, solar cell layer, EVA, high temperature cohere polyester layer and backsheet layer from top to bottom successively lamination arrange, and constitute one by the lamination encapsulation.
The thickness range of described high temperature bond polyester layer is 49～225um.
Described high temperature bond polyester layer is made of pet film coating and the fire retarding epoxide resin glue that is coated in its one or both sides.
The beneficial effects of the utility model are: the layer of this solar cell module back veneer with layer between pulling force big, peel strength is big, particularly EVA and high temperature cohere peel strength between the polyester layer greater than 200N, unfailing performance height, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a three-dimensional exploded view of the present utility model.
Wherein: 1. toughened glass layer, 2.EVA, 3. solar cell layer, 4.EVA, 5. high temperature coheres polyester layer, 6. backsheet layer.
Embodiment
As shown in Figure 1, a kind of solar cell module back veneer, have toughened glass layer 1, EVA2, solar cell layer 3, EVA4 and backsheet layer 6, have additional high temperature between EVA4 and the backsheet layer 6 and cohere polyester layer 5, high temperature bond polyester layer 5 is made of pet film coating and the fire retarding epoxide resin glue that is coated in its one or both sides; Described toughened glass layer 1, EVA2, solar cell layer 3, EVA4, high temperature cohere polyester layer 5 and backsheet layer 6 from top to bottom successively lamination arrange, and constitute one by the lamination encapsulation.
Embodiment:
Equipment: laminating machine.
Material: toughened glass, EVA, the battery sheet, backboard, it is ADH that high temperature coheres polyester layer, ADH thickness is 125um, the product of ADH are by name: GTS 3480-HIGH TEMPERATURE ADHESIVE POLYESTERTAPES, concrete model is 348131 under GTS 3480 series, and the composition of this type is: GTS 3480tapesare constructed from Polyethylene Terephthalate film coated on one orboth sides with a fire retardant epoxy based adhesive system (GTS 3480 types are to be made of with the fire retarding epoxide resin glue that is coated in its one or both sides pet film coating PET).
Processing step is as follows:
One, lamination: carrying toughened glass correct position place to the lamination platform, matte upwards checks that outward appearance has or not bad; Get the EVA of a free from dust that cuts, nothing scuffing, breakage, dirty trace, matte upwards is tiled on the toughened glass; Put into the good battery strings of welding, guarantee that string and string spacing are 3 ± 1mm; Carrying out circuit by the lamination drawing connects; Get another EVA matte and carefully be layered on gently downwards on the battery sheet, require to crack, draw busbar in the relevant position according to stacked graph; Get an ADH being layered on the EVA gently, can not surpass toughened glass edge 5mm, draw busbar along the limit; Put a back veneer material gently, composite surface is downward, draws busbar.
Two, lamination: checkout facility, the change parameter, parameter setting is 142 ℃, pumpdown time 4min, lamination time 15min; Spread two-layer tetrafluoro cloth earlier at feed end, above the assembly that lamination is good is placed on, cover two-layer tetrafluoro cloth in the above again; Assembly is fed to assigned address in the laminating machine, the beginning lamination; After assembly takes the dish out of the pot, cooling earlier five minutes, after with the assembly upset, glass is check upwards; The no abnormal back of assembly chamfered edge.
Three, frame up: with screw long and short section bar is connected into L type section bar, beat behind the glue and frame up in 5 minutes; Get the qualified battery module glass of lamination towards on move on the platform that frames up, carry out surface and the cleaning of edge EVA, simultaneously preceding working procedure is tested; Two L type section bars of having played glue are spliced on the assembly, should possess distance about 1.5mm with frame around the assembly, the aluminium frame is fixed for all the other two jiaos with screw; Assembly is upwards moved to frame loader,, close pneumatic operated valve, be fixed, mend glue at the seam crossing of assembly and section bar with making the glue rifle near on one side; Glue is played in root both sides at busbar, guarantees the root sealing; Glue is played in the terminal box bottom surface, terminal box be pressed onto on the assembly back silica gel must from around overflow; With pack into the bayonet socket of terminal box of busbar, with choosing busbar on the screwdriver to check whether the terminal box busbar clamps.
