Description
Technical field
The present invention relates to solar module field, particularly relates to a kind of solar energy backboard with high barrier.
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, current existing structure is too
Sun energy backboard unstable properties, reflectance, ageing resistace, block-water performance are poor, and structure complexity causes processed complex, makes production become
This increase.The polyester molecule chain of the most existing mylar is submissiveer, in order to avoid interatomic row in banking process
Repulsion, is susceptible to relative motion so that occur more space in accumulation body, and the little molecular melting such as oxygen, steam is at PET
In, owing to mylar is medium barrier material, limited to the barrier of steam and oxygen, cause whole solar energy backboard
Intercept impacted, be unfavorable for life-time service.
Summary of the invention
The applicant, for above-mentioned existing issue, has carried out Improvement, it is provided that a kind of have high barrier too
Sun can backboard, it has, and steam, oxygen-barrier property be good, the advantage of good mechanical performance, effectively meets the life of solar energy backboard
Produce requirement.
The technical solution adopted in the present invention is as follows:
A kind of solar energy backboard with high barrier, including mylar, in the side of described mylar, order is logical
Crossing high reflection layer, the bonding weathering layer of tack coat, the opposite side order of described mylar is by high reflection layer, barrier layer, bonding
The bonding weather-proof tack coat of layer；Described barrier layer includes oxygen barrier layer and aqueous vapor separation layer.
Its further technical scheme is:
Described oxygen obstruction layer thickness is 10～110 microns, and the thickness of described aqueous vapor separation layer is 5～160 nanometers；
The thickness of described mylar is 80～400 microns；
The thickness of described tack coat is 0.5～40 micron；
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, 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 is high, and it is long that it has the life-span, weatherability height, high reflectance and outstanding resisting
Ageing properties, the present invention use gelatin materials be oxygen barrier layer, employing inorganic material be aqueous vapor separation layer, make solar energy backboard
Low cost, steam can be intercepted respectively with oxygen by aqueous vapor separation layer with oxygen barrier layer, and beneficially the barrier of backboard, makes
Steam and the OTR oxygen transmission rate of solar energy backboard substantially reduce.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein: 1, weathering layer；2, tack coat；3, mylar；4, weather-proof tack coat；5, high reflection layer；6, barrier layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
A kind of solar energy backboard with high barrier includes mylar 3, in the side of mylar 3 order by height
Reflecting layer 5, the bonding weathering layer of tack coat 21, the opposite side order of mylar 3 is by high reflection layer 5, barrier layer 6, tack coat 2
Bonding weather-proof tack coat 4；Barrier layer 6 includes that oxygen barrier layer and aqueous vapor separation layer, oxygen obstruction layer thickness are 10～110 micro-
Rice, the thickness of aqueous vapor separation layer is 5～160 nanometers, and above-mentioned oxygen barrier layer uses gelatin materials to make, above-mentioned aqueous vapor separation layer
Employing inorganic material is made.
The thickness of mylar 3 is 80～400 microns.The thickness of tack coat 2 is 0.5～40 micron.Weather-proof tack coat 4
Thickness is 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, 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 is high, and it is long that it has the life-span, weatherability height, high reflectance and outstanding resisting
Ageing properties, the present invention use gelatin materials be oxygen barrier layer, employing inorganic material be aqueous vapor separation layer, make solar energy backboard
Low cost, steam can be intercepted respectively with oxygen by aqueous vapor separation layer with oxygen barrier layer, and beneficially the barrier of backboard, makes
Steam and the OTR oxygen transmission rate of solar energy backboard substantially reduce.
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.
