Technical field
The present invention relates to technical field of solar batteries, more particularly to a kind of compound notacoria of solaode and its preparation side
Method.
Background technology
Solar photovoltaic assembly mainly by glass cover-plate, ethylene-vinyl acetate copolymer (EVA), cell piece, backboard, connect
Line box and frame etc. are constituted.Support and protective effect because backboard rises to cell piece, and backboard as direct with extraneous natural ring
The encapsulating material of border bump contact, its performance directly determines the generating efficiency and service life of photovoltaic module, and backboard is necessary
Possess excellent insulating properties, water vapor barrier property and weatherability etc., therefore impact of the backboard performance to solar photovoltaic assembly is very
It is important.Backboard plays a key effect to battery, output, security reliability.The solaode of poor-performing
Backboard uses 8～10 years under ordinary climate environment, uses 5～8 years under special environment (environment such as plateau, island, wetland),
There are the bad phenomenon such as delamination, cracking, foaming, flavescence, so as to cause battery module to come off, cell piece sliding, battery it is effective
Situations such as output is reduced, in addition occur electricity beat arc phenomenon, cause battery component to burn and inspire fire, cause personnel to damage
And property loss.
Existing backboard is mainly with polyethylene terephthalate (PET) as substrate, compound in its single or double
Or coating has functional fluorine material, so that backboard has good barrier, weather-proof and insulating properties, therefore, substrate outside
The performance of fluorine material just seem particularly critical.
Chinese patent 201110188877.4 discloses a kind of solar cell backboard, including gas barrier layer, resist processing layer and
Some outer covering layers, and at least one layer outer covering layer is the composite membrane by made by polyimides and Teflon, the composite membrane can be with
Be fitted by polyimide film and Teflon film constitute, or polyimides and Teflon co-extruded films, choke
Layer can effectively intercept aqueous vapor, and resist processing layer is suitable to laminating processing or provides buffering effect, and polyimide resin has weatherability
Matter, can protect gas barrier layer, Teflon then can further block aqueous vapor and uvioresistant, but the scheme of the prior art is prepared too
It is positive can battery back-sheet weak heat-dissipating, stain resistance is poor, in the service life for a certain degree reducing solaode.
Chinese patent 201310719113.2 discloses a kind of solar cell backboard, including basic unit, and described basic unit is
Plastic layer, the surface of described basic unit both sides is connected with resin bed by adhesive layer respectively, and described resin layer surface is provided with guarantor
Cuticula, described protecting film includes being arranged on the silicon oxide coatings of the resin layer surface, described silicon oxide coatings table
Face is connected with film layer by another layer of adhesive layer, and described plastic layer adopts polyethylene terephthalate, described resin
Layer is polyvinylidene fluoride resin layer, and described adhesive layer is ethyl acetate layer, and described film layer is polyimide film layer.Should
Solar energy backboard tensile strength prepared by prior art is good, water vapor transmittance is high, percent thermal shrinkage is high, but still there is radiating
The problems such as difference, stain resistance difference, these can all affect the electric property of solaode.
In prior art, part solar battery back film (backboard) can occur xanthochromia under the irradiation of ultraviolet light, cause the back of the body
The molecular composition of film layer is partially destroyed, and the overall performance of notacoria declines, while the reflectance reduction of notacoria, affects the whole of component
Body is exported.And, if the heat transfer coefficient of battery sheet material is poor, local temperature is too high to cause material to gasify, so as in the back of the body
There is bulge in film, and bulge can also gradually expand causes the material oxidation of surrounding to go bad, and affects the service life of component.It can be seen that, open
The good solar battery back film of a kind of intensity height, good water vapor rejection performance, uvioresistant, good heat dissipation, anti-soil energy is sent, becomes one
Individual technical problem.
The content of the invention
For above-mentioned technical problem, the invention provides a kind of compound notacoria of solaode.Using the technology of the present invention
Scheme, can prepare good isolation performance, aging resistance, good heat dissipation, corrosion resistant solar battery back film.
The technical scheme is that：A kind of solaode is combined notacoria, successively including the first notacoria, the second notacoria,
3rd notacoria, between the first notacoria and the second notacoria, between the second notacoria and the 3rd notacoria also have tack coat, the first notacoria with
The EVA adhesive film of solaode is adjoined, it is characterised in that：First notacoria is poly tetrafluoroethylene；Second notacoria is
The composite membrane that the adipose membrane of poly terephthalic acid second two is composited with gas-phase silica；3rd notacoria is Merlon-oxidation
The composite membrane of zirconium-politef composition.
Further, the zirconium oxide in the 3rd notacoria is nano zircite.
Further, the zirconium oxide in the 3rd notacoria is by hexafluoropropylene oxide oligomer type surfactant, titanium
The modified nano zircite of acid esters coupling agent, high molecular weight compatibilizer.
Further, the Merlon is coated on the zirconic surface of the type surfactant, and formation is with zirconium oxide
Core, Merlon are the structure of shell.
Further, as a kind of optional embodiment of the present invention, first notacoria can also use Merlon-oxidation
The composite membrane of zirconium-politef composition is substituting poly tetrafluoroethylene.
The invention also discloses the preparation method of the compound notacoria of the solaode, it is characterised in that：Comprise the following steps：
1) modified zirconia is aoxidized：Nano zircite is dried into 30min at 110 DEG C, is then placed in filling the container of toluene solvant
In, after ultrasonic disperse 20min, titanate coupling agent is added, kept for 3 hours in 100 DEG C of water-bath, Temperature fall, sucking filtration,
It is dried, product is placed in standby in exsiccator；
2) zirconium oxide-Merlon compound particle is prepared：Modified zirconium oxide is added into deionized water, acrylic acid high score
