Technical field
This utility model is related to a kind of high reflectance poe packaging adhesive film, belongs to packaging adhesive film for solar cell and its preparation
Field.
Background technology
Solar energy has the advantages that safe and reliable, noise-less pollution, no atmospheric pollution, renewable, broad covered area, is current
One of important new forms of energy, main application form is solar cell power generation.Now with solaode be continually changing and
Development, by improving encapsulating material and packaging technology, thus improving the service life of solaode, reduces solar electrical energy generation
Cost becomes one of key issue.Solar module includes the knot such as crystal-silicon battery slice, packaging adhesive film, backboard and glass and constitutes
Point, wherein encapsulating material plays very important effect in assembly, and it is the crucial material of bonding cell piece and backboard and glass
Material, not only requires it to have good caking property, to ensure the stability of solar module structure, prevents harmful substance from oozing
Enter, also will have good ageing-resistant performance, to improve the service life of assembly.
For solar module, the packaging adhesive film between cell piece and backboard does not need very high printing opacity
Rate, but need preferable adhesive property, there is excellent weatherability simultaneously, big multicompartment factory uses up and down in cell piece at present
Identical transparent enclosure glued membrane, the utilization ratio that this may result in sunlight is not high, if made between backboard and cell piece
With white packaging adhesive film it is possible to increase the reflectance of backboard side, thus improving sun light utilization efficiency, and then improve sending out of battery
Electrical efficiency.
Packaging adhesive film for solar cell mainly uses eva(ethylene-vinyl acetate copolymer at present) glued membrane, but
Eva is susceptible to light-heat aging, thus leading to eva degraded aging, producing xanthochromia, hydraulic performance decline, and then having a strong impact on assembly
Generating efficiency and service life.
Content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of excellent weather resistance, can improve the sun simultaneously
The high reflectance poe packaging adhesive film of energy battery component generating efficiency.
The purpose of this utility model is achieved in that
A kind of high reflectance poe packaging adhesive film, it includes the poe layer arranged up and down and the 2nd poe layer, and described
One poe layer is transparent poe, and described 2nd poe layer is white poe.
As one kind preferably, the thickness range of a described poe layer is 100～500 microns.
As one kind preferably, the thickness range of described 2nd poe layer is 50～500 microns.
As one kind preferably, the upper and lower surface of this high reflectance poe packaging adhesive film has stamping.
It is terrace with edge structure as a kind of preferred, above-mentioned decorative pattern, between adjacent terrace with edge and terrace with edge, have gap.
As one kind preferably, this terrace with edge structure can be Rhizoma Sparganii platform, truncated rectangular pyramids, five terrace with edges, six terrace with edges or eight terrace with edges knot
Structure.
Compared with prior art, the beneficial effects of the utility model are:
The poe adopting in this utility model is the copolymer of ethylene and octene, has saturated fat chain structure, has good
Weatherability, ultraviolet aging resistance, excellent heat-resisting and resistance to low temperature, using wide temperature range, and cost performance is high, Yi Jia
Work.This high reflectance poe packaging adhesive film is used between cell piece and backboard, will not pollute cell piece after heat lamination, and the of white
Two poe layers can increase the reflectance of sunlight, and gained assembly, while increasing the service life, can also improve sending out of assembly
Electrical efficiency.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 adopts the structural representation of six terrace with edge decorative patterns for this utility model surface.
Wherein:
First poe layer 1
2nd poe layer 2.
Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of high reflectance poe packaging adhesive film that this utility model is related to, it includes arranging up and down
First poe layer 1 and the 2nd poe layer 2, a described poe layer 1 is transparent poe, and described 2nd poe layer 2 is white poe.
The thickness range of a described poe layer 1 is 100～500 microns.
The thickness range of described 2nd poe layer 2 is 50～500 microns.
As one kind preferably, the upper and lower surface of this high reflectance poe packaging adhesive film has stamping.
It is terrace with edge structure as a kind of preferred, above-mentioned decorative pattern, between adjacent terrace with edge and terrace with edge, have gap.Gap is in layer
During pressure be beneficial to aerofluxuss it is ensured that lamination density.
As one kind preferably, this terrace with edge structure can be Rhizoma Sparganii platform, truncated rectangular pyramids, five terrace with edges, six terrace with edges or eight terrace with edges knot
Structure.
Wherein the first poe layer 1 plays the effect of bonding cell piece, and the 2nd poe layer 2 plays the effect of bonding backboard, simultaneously
The reflectance of sunlight can be increased, improve the output of cell piece.
This utility model high reflectance poe packaging adhesive film adopts double-layer coextrusion technology one-step shaping, is increasing reflectance
Ensure that poe has good caking property with backboard and cell piece simultaneously, make gained assembly have preferable ageing-resistant performance, can
Improve the output of assembly with the life-span improving assembly simultaneously.First poe layer 1 and the 2nd poe layer 2 are respectively by corresponding resin
Particle and auxiliary agent melt extrude in different extruders, are converged in same die head by respective runner, be then passed through extrusion,
Curtain coating, pressing, cooling shaping make the poe packaging adhesive film of above-mentioned high reflectance.
Add various auxiliary agents in process of production the first poe layer 1 and the 2nd poe layer 2 are modified, improve its aging resistance
Etc. combination property.
2nd poe layer 2, as high reflection layer, is interpolation white filler in transparent poe, such as: titanyl compound, the oxygen of silicon
The oxide of compound, the oxide of aluminum and/or stannum, it is possible to use one of which and/or several mixture, preferably uses titanium
Oxide, more preferably using titanium dioxide (Du Pont), has no particular limits to the source of described additive, can purchase from the market
Buy gained.Because the additive that the 2nd poe layer 2 is used has opaqueness, sunlight can be reflexed to cell piece simultaneously
On, it is possible to use the reflectance increasing sunlight effectively to lift the output of solar module；In addition, the 2nd poe
The acceptable effectively shielding of ultraviolet of layer 2, prevents ultraviolet from entering backboard, such that it is able to be effectively protected backboard, prevents ultraviolet
The destruction to pet base material for the line, and then increase the weatherability of backboard, extend the service life of backboard, also just indirectly extend group
The service life of part.
