Abstract
The utility model relates to a kind of high-reflectivity EVA packaging adhesive film, it is characterized in that it comprises to comprise successively from top to bottom upper strata transparent EVA layer (1), middle white EVA layer (2) and lower floor's transparent EVA layer (3).This high-reflectivity EVA packaging adhesive film has bondingly firmly increases reflectivity, and cell piece part can not be blocked, and assurance can increase the advantage of assembly output rating.
Description
Technical field
The utility model relates to a kind of EVA packaging adhesive film, relates in particular to a kind of high-reflectivity EVA packaging adhesive film, mainly uses between solar cell device and back veneer material, belongs to solar module encapsulation field.
Background technology
Sun power is a kind of green non-pollution and the inexhaustible energy, mainly utilizes at present solar module to convert thereof into electric energy, and then as other purposes, as: lighting circuit, water-heater, power tool etc.Because solar cell is in outdoor application, environment is severe, therefore need to be protected.Conventionally use glass, packaging adhesive film, backboard to be encapsulated.
Wherein, the effect of packaging adhesive film is in encapsulation solar cell, and glass and backboard are coupled together, and applying maximum is EVA glued membrane, is generally to use in the middle of two identical EVA glued membranes are enclosed in solar cell.This glued membrane is crosslinked in lamination of solar battery components process, in the time of by solar cell package, glass and backboard is coupled together.In use, tend to because the aging output rating of solar cell that causes of EVA reduces.
For solar module, the packaging adhesive film between cell piece and backboard does not need very high transmittance, but needs good adhesiveproperties, will have excellent weathering resistance simultaneously.Current multicompartment factory is greatly at the identical EVA glued membrane using up and down of cell piece, this may reduce the reflectivity of backboard side, and then the output rating of reduction cell piece, in order to address this problem, on market, there is now the white EVA packaging adhesive film of production to replace original transparent EVA packaging adhesive film, it is bonding not firm that but pure white EVA packaging adhesive film easily occurs with backboard in lamination process, the problem of backboard and EVA layering; In addition, in lamination process, EVA melt-flow, has part white EVA and overflows to cell piece front, can cause like this cell piece to be partly blocked, and can reduce equally the output rating of assembly.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of bonding firm, and cell piece part can not be blocked, the high-reflectivity EVA packaging adhesive film of Assurance component output rating.
The purpose of this utility model is achieved in that
A high-reflectivity EVA packaging adhesive film, is characterized in that it comprises and comprises successively from top to bottom upper strata transparent EVA layer, middle white EVA layer and lower floor's transparent EVA layer.
As a kind of preferred, the thickness of described upper strata transparent EVA layer and lower floor's transparent EVA layer is 100 ~ 300 microns.
As a kind of preferred, the thickness of described middle white EVA layer is 50 ~ 500 microns.
As a kind of preferred, the upper and lower surface stamping of high-reflectivity EVA packaging adhesive film.
As a kind of preferred, decorative pattern is six terrace with edge structures, gapped between six adjacent terrace with edges and six terrace with edges.
Compared with prior art, the beneficial effects of the utility model are:
In the use procedure of the utility model high-reflectivity EVA packaging adhesive film, not only can improve reflectivity, increase the generating efficiency of solar module; Can also intercept ultraviolet ray, protection backboard, thereby the work-ing life of prolongation assembly; In addition, due to the upper and lower two-layer transparent EVA that is of this glued membrane, can avoid white glued membrane to pollute cell piece, when increasing generating efficiency, can not affect the outward appearance of assembly.Therefore this high-reflectivity EVA packaging adhesive film has bondingly firmly increases reflectivity, and cell piece part can not be blocked, and assurance can increase the advantage of assembly output rating.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high-reflectivity EVA packaging adhesive film.
Fig. 2 is the utility model high-reflectivity EVA packaging adhesive film surface imprint decorative pattern schematic diagram.
Wherein:
Upper strata transparent EVA layer 1, middle white EVA layer 2, lower floor's transparent EVA layer 3.
Embodiment
Referring to Fig. 1, a kind of high-reflectivity EVA packaging adhesive film that the utility model relates to, it comprises and comprises successively from top to bottom upper strata transparent EVA layer 1, middle white EVA layer 2 and lower floor's transparent EVA layer 3.
Upper strata transparent EVA layer 1 and lower floor's transparent EVA layer 3 play respectively the effect of bonding cell piece and bonding backboard, and middle white EVA layer 2 can increase reflectivity, improve the output rating of cell piece.
The thickness of described upper strata transparent EVA layer 1 and lower floor's transparent EVA layer 3 is 100 ~ 300 microns;
The thickness of described middle white EVA layer 2 is 50 ~ 500 microns.
The utility model high-reflectivity EVA packaging adhesive film adopts three-layer co-extruded technology one-step moulding, when increasing reflectivity, can guarantee there is good cementability between EVA and cell piece and backboard.Upper strata transparent EVA layer 1, middle white EVA layer 2 and lower floor's transparent EVA layer 3 this three layers of materials are melt extruded in different forcing machines by corresponding resin particle and auxiliary agent respectively, runner by separately converges in same die head, then through extruding, curtain coating, pressing, coolingly make above-mentioned high-reflectivity EVA packaging adhesive film.
In the present embodiment, add various auxiliary agents each layer of EVA carried out to modification, improve the over-all propertieies such as its ageing resistance.
In the present embodiment, middle white EVA layer 2 is as high reflection layer, in transparent EVA, to add white filler, as: the oxide compound of the oxide compound of titanyl compound, aluminium, the oxide compound of silicon and/or tin, can use wherein a kind of and/or several mixtures, preferably use titanyl compound, more preferably use titanium dioxide (Du Pont).The utility model has no particular limits the source of described additive, can buy from the market gained.Because the additive using in middle white EVA layer 2 has opaqueness, sunlight can be reflexed on cell piece, can utilize and increase the power that sunlight reflectivity promotes solar module; In addition, middle white EVA layer 2 is shielding of ultraviolet effectively, prevents that ultraviolet ray from entering backboard; thereby can protect backboard, prevent the destruction of ultraviolet ray to PET base material, and then increase the weathering resistance of backboard; extend the work-ing life of backboard, also indirectly extended the work-ing life of assembly.The thickness of described middle white EVA layer 2 is 50 ~ 500 microns, preferably 200 ~ 300 microns, and more preferably 200 ~ 250 microns.
Referring to Fig. 2, in the present embodiment, as required can be at the upper and lower surface stamping of high-reflectivity EVA packaging adhesive film.This decorative pattern is six terrace with edge structures, gapped between six adjacent terrace with edges and six terrace with edges.Gap is beneficial to exhaust in lamination process, guarantees the density of lamination.This high-reflectivity EVA packaging adhesive film, between cell piece and backboard, can not pollute cell piece, and white size rete can increase reflectivity after heat lamination, and then improves the generating efficiency of assembly.
