Description
Technical field
The present invention relates to solar-energy photo-voltaic cell field, particularly relate to a kind of solar battery back with high insulating property
Plate.
Background technology
Solar energy, as a kind of environmental protection, the inexhaustible energy, replaces the optimal choosing of tradition thermal power generation beyond doubt
Select, owing to solaode needs to be chronically exposed to outdoor practicality, so the cell piece in photovoltaic module needs to be protected by, come
Prevent impact and the vertical view of the environmental factorss such as the steam in air, oxygen, ultraviolet.Solar energy backboard is whole solaode
One of accessory, act primarily as mechanical support and effect that protection cell piece permeates from environmental factors, how to improve the exhausted of backboard
Edge is always the research emphasis of the sector.
Summary of the invention
The applicant, for above-mentioned existing issue, has carried out Improvement, it is provided that a kind of sun with high insulating property
Energy battery back-sheet, it can improve the insulating properties of solar cell backboard further and extend its service life.
The technical solution adopted in the present invention is as follows:
A kind of solar cell backboard with high insulating property, including mylar, the both sides table of described mylar
Face cover anti-reflection film, in described mylar with anti-reflection film side by tack coat connect weathering layer, described mylar
With the opposite side of anti-reflection film also by tack coat attachment structure enhancement layer, the most bonding weather-proof in the outside of described structure enhancement layer
Tack coat.
Its further technical scheme is:
The thickness of described mylar is 250～300 microns；
The thickness of described weathering layer is 10～50 microns；
The thickness of described structure enhancement layer is 100～300 microns, and the thickness of described tack coat is 2～35 microns；
Described weathering layer is fluorine-containing weathering layer；
The thickness of described weather-proof tack coat is 40～60 microns.
Beneficial effects of the present invention is as follows:
The weathering layer material of solar cell backboard of the present invention is fluorine-containing weathering layer, and it has a low cost, good environmental protection,
Its mechanical property, adhesion strength are also good than conventional backing plate, and back board structure is more stable, and whole solar energy is supported protective effect more
Adding prominent, by arranging anti-reflection film in polyester film surface, it can not only improve the transmittance of thin film, and substantially increases absolutely
Edge performance.The solar cell backboard that the present invention provides is substantially better than existing backboard, and the setting of mylar improves the most absolutely
Edge, aqueous vapor barrier, its wet-heat resisting ageing-resistant performance are high, and the life-span is long, and weatherability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein: 1, weathering layer；2, tack coat；3, mylar；4, structure enhancement layer；5, weather-proof tack coat.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As it is shown in figure 1, a kind of solar cell backboard with high insulating property, including mylar 3, mylar 3
Both side surface cover anti-reflection film, connect weathering layer 1, polyester with the side of anti-reflection film by tack coat 2 in mylar 3
Film 3 with the opposite side of anti-reflection film also by tack coat 2 attachment structure enhancement layer 4, the most bonding resistance in the outside of structure enhancement layer
Wait tack coat 5.The thickness of mylar 3 is 250～300 microns.The thickness of weathering layer 1 is 10～50 microns.Structure enhancement layer
Thickness be 100～300 microns, the thickness of tack coat is 2～35 microns.Weathering layer 1 is fluorine-containing weathering layer.Weather-proof tack coat 5
Thickness be 40～60 microns.
The weathering layer material of solar cell backboard of the present invention is fluorine-containing weathering layer, and it has a low cost, good environmental protection,
Its mechanical property, adhesion strength are also good than conventional backing plate, and back board structure is more stable, and whole solar energy is supported protective effect more
Adding prominent, by arranging anti-reflection film in polyester film surface, it can not only improve the transmittance of thin film, and substantially increases absolutely
Edge performance.The solar cell backboard that the present invention provides is substantially better than existing backboard, and the setting of mylar improves the most absolutely
Edge, aqueous vapor barrier, its wet-heat resisting ageing-resistant performance are high, and the life-span is long, and weatherability is high.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees right
Requirement, in the case of the basic structure of the present invention, the present invention can make any type of amendment.
