Description
Technical field
This utility model belongs to area of solar cell, is related to a kind of packaging adhesive film used for solar batteries, and in particular to one
Plant the packaging adhesive film without white flange.
Background technology
Since being born from life on earth, the just main infrared radiant energy existence provided with the sun, and also understand from ancient human
With sun dry part, and the method as food is made, such as salt manufacturing and solarization cured fish etc..In the situation that Fossil fuel is reduced increasingly
Under, solar energy has become the important component part that the mankind use the energy, and is constantly developed.
As solaode is in outdoor application, bad environments, it is therefore desirable to protected.Be usually used glass,
The structure such as packaging adhesive film and backboard is encapsulated.The effect of packaging adhesive film is, while solaode is encapsulated, to incite somebody to action
Glass and backboard are coupled together, and the glued membrane is crosslinked during lamination of solar battery components, by the same of solar cell package
When glass and backboard are coupled together.For solar module, packaging adhesive film between cell piece and backboard is simultaneously not required to
Light transmittance that will be very high, but preferable adhesive property is needed, while excellent weatherability will be had.Big multicompartment factory exists at present
The transparent EVA glued membrane for using up and down of cell piece, this may reduce the reflectance of backboard side, and then reduce the output of cell piece
Power.In order to solve the problem, there are production white EVA packaging adhesive films currently on the market to replace original transparent EVA packaging plastic
Film, but easily appearance is bonding with backboard loosely in lamination process for pure white EVA packaging adhesive films, and backboard is layered with EVA
Problem；In addition, in lamination process, EVA melt-flows have partial white EVA and overflow to cell piece front, can so lead
Cause cell piece part to be blocked, can equally reduce the output of component.
The content of the invention
This utility model purpose is to provide a kind of packaging adhesive film without white flange to overcome the deficiencies in the prior art.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of packaging adhesive film without white flange, institute
Stating packaging adhesive film includes that at least one of which clear layer and at least one of which non transparent layer, the clear layer and non transparent layer alternating set
Put, in the two-layer outermost layer of the packaging adhesive film, at least one layer is the clear layer.
Optimally, the packaging adhesive film is made up of with the non transparent layer for being formed in the clear layer any surface clear layer.
Further, another surface of the non transparent layer is furnished with and the multiple projections of the clear layer material identical, institute
State raised to form the block of array or being in strip.
Optimally, when two surfaces of the non transparent layer are respectively formed the clear layer, the non transparent layer is by nontransparent
Substrate layer and at least one of which transparent substrate layer composition being arranged in the nontransparent substrate layer；The transparent substrate layer is prolonged
Stretch direction parallel with the bearing of trend of the clear layer.
Further, when the transparent substrate layer is multilamellar, their interval settings in the nontransparent substrate layer.
Optimally, the material of the clear layer and the non transparent layer is independently of one another EVA or POE.
As above-mentioned technical proposal is used, this utility model has following advantages compared with prior art：This utility model
Packaging adhesive film without white flange is by being arranged to include at least one of which clear layer and at least one of which non transparent layer and transparent
Layer and non transparent layer are arranged alternately so that in the two-layer outermost layer of packaging adhesive film, at least one layer is clear layer, so can be by
The clear layer and glassy layer are bondd and another outermost layer is bondd with backboard, can so avoid polluting cell piece and
Ensure its presentation quality；And ultraviolet can be intercepted, backboard is protected, so as to extend the service life of component.

Specific embodiment
This utility model is further described below in conjunction with embodiment.
Embodiment 1
The present embodiment provides a kind of packaging adhesive film without white flange, including clear layer 11 and non transparent layer 12.
Wherein, at least a layer of clear layer 11 and non transparent layer 12, they are arranged alternately so that non transparent layer 12 is formed
On the surface of clear layer 11.But, in the two-layer outermost layer of packaging adhesive film at least one layer be clear layer 11, so as to by it with
Glassy layer is bondd so that it is guaranteed that the light impingement rate of whole solaode.The material of clear layer 11 and non transparent layer 12 is mutual
EVA or POE independently is, non transparent layer 12 is because titanium dioxide, aluminium dioxide, dioxy are added in the matrix of EVA or POE
The inorganic filler powder such as SiClx, carbon black.In the present embodiment, as shown in figure 1, packaging adhesive film only by layer of transparent layer 11 and is formed in
One layer of non transparent layer 12 of 11 any surface of clear layer is constituted；The thickness of clear layer 11 and non transparent layer 12 can enter as needed
Row is selected, within being 1mm with being generally independent of one another.
Embodiment 2
As shown in Fig. 2 the packaging adhesive film without white flange, including clear layer 11 ' and non transparent layer 12 '.Wherein, clear layer
11 ' are two-layer, and non transparent layer 12 ' is formed between two-layer clear layer 11 '.As two surfaces of non transparent layer 12 ' are respectively formed
During bright layer 11 ', the non transparent layer 12 ' by nontransparent substrate layer 121 ' and be arranged in nontransparent substrate layer 121 ' at least one
