Description
Technical field
The present invention relates to photovoltaic module technical field, be specifically related to a kind of novel solar battery notacoria.
Background technology
Solar photovoltaic assembly is the important component part of photovoltaic module, plays protection, insulate, intercepts the effect such as steam,
Therefore the quality of photovoltaic component back plate performance directly influences service life and the transform ratio of power generation of photovoltaic module, and backboard is to battery
Sheet plays protection and supporting role, it is desirable to have reliable insulating properties, water preventing ability, resistance to ag(e)ing；At present, the compound photovoltaic module back of the body
Plate structure mostly is fluorine material layer/pet layer/PE layer or PEVA tack coat, and layers of material is bonding by adhesive, and gross thickness is
250～400 μm, office side's voltage of this traditional structure backboard can only achieve 1000～1200V in this thickness range, if wanted
Meeting the application of supertension assembly, can only take the mode of thickened material, cost rises significantly, and blocked up application inconvenience.
Solar energy backboard typically has three-decker, and outer protective layer is fluoropolymer layer, has good environment resistant
Erosiveness, intermediate layer be can the polyester film layer of biaxial tension, there is good insulating properties and mechanical property, internal layer
For fluoropolymer layer or EVA copolymer layer, with encapsulating material EVA, there is good caking property.?
In prior art, PET film all can not be bondd by hot composition process with fluorine film, this not only production to PET composite membrane make
Become the biggest restriction, also the performance of Related product is produced harmful effect.The preparation method of back veneer material the most both at home and abroad, greatly
All to smear polyurethane adhesive respectively on two surfaces of PET Obstruct membrane, be combined the most respectively fluorine film and fluorine film, fluorine film and
EVA film, fluorine film and PE film, this preparation method mainly solves fluorine film and PET film, the caking property of PET film and EVA (PE) film is asked
Topic, but still existing defects: use stage composite means, i.e. first after a surface coating a compound tunic of PET film, then
At another surface coating another tunic compound of PET film, operation is more complicated；Domestic polyurethane adhesive is required for import,
The production cost making solar energy backboard is too high；Owing to polyurethane adhesive is solvent based adhesive, needing to use substantial amounts of has
Machine solvent, and environment can be caused certain pollution by these organic solvents, and the health of operator also can be produced bad
Impact, easily causes the problem in terms of safety and environmental protection；Described polyurethane glue-line can drop during life-time service
Solve, cause interlaminar separation and the phenomenon come off, and then solar module can be made to be scrapped because losing protection；There is factory at present
Family produces fluoropolymer membrane, PET film and olefines co-extrusion film, and its constituent is defective, thus its permeability rate is too high, barrier property
Difference, hot strength is the strongest.
Summary of the invention
It is an object of the invention to provide a kind of novel solar battery notacoria, solve in above-mentioned prior art problem
Or it is multiple.
According to a kind of novel solar battery notacoria of the present invention, a kind of novel solar battery notacoria, including: contain
Fluorine film layer, polyethylene terephthalate film layer and olefines co-extrusion film layer, described fluoropolymer membrane layer and described poly-terephthaldehyde
Connected by the first adhesive layer between acid glycol ester film layer, described polyethylene terephthalate film layer and described olefines
Connected by the second adhesive layer between co-extrusion film layer；Described olefines co-extrusion film layer is made up of following component, homopolymerisation polyethylene, altogether
One or more of poly-polyethylene, HOPP, COPP, block copolymerization polypropylene and silane grafted polyethylene.
In some embodiments, described olefines co-extrusion film layer also includes catalyst, antioxidant, ultraviolet (UV) resistant agent, steady
Determine agent and implant.By adding catalyst, antioxidant, ultraviolet (UV) resistant agent, stabilizer and implant so that olefines is total to
Extruded film layer barrier property is more preferable, and permeability rate reduces, and electrical insulation capability promotes.
In some embodiments, described catalyst is dibutyl tin laurate, stannous octoate, dibutyltin diacetate
With one or more in tin dilaurate dioctyl tin.The reaction being easy between each component.
In some embodiments, described antioxidant include antioxidant be four [β-(3 ', 5 '-di-t-butyl-4 '-hydroxy benzenes
Base) propanoic acid] pentaerythritol ester and tricresyl phosphite (2,4-di-tert-butyl-phenyl) ester.Antioxidant can suppress polymer effectively
Thermo-oxidative ageing.
In some embodiments, described ultraviolet (UV) resistant agent is Octabenzone, three (Isosorbide-5-Nitraes one or two
Tert-butyl-phenyl) one or more in phosphorous acid and double (octadecyl) tetramethylolmethane two phosphorous fat.It is effectively prevented material
Xanthochromia and blocker rationality loss of energy, suppress or weaken photodegradation, improve light aging resisting property.
In some embodiments, described stabilizer is the mixture of lead sulfate tribasic and dibasic lead phosphite, group
Amount part is as follows, lead sulfate tribasic: dibasic lead phosphite is 90 parts: 10～16 parts.Lead sulfate tribasic and dibasic phosphorous
Lead plumbate is excellent stabilizer, but individually uses, and there is certain defect in effect, therefore, under above-mentioned mixing match,
Its stablizing effect is greatly increased, and after making backboard molding, barrier property is more preferable.
In some embodiments, described implant selected from titanium dioxide, glass fibre, carbon fiber, Pulvis Talci, calcium carbonate,
One or more in wollastonite and white carbon black.
In some embodiments, described olefines co-extrusion film layer is total to by component A film layer, B component film layer and C component film layer
Squeeze composition, wherein, the accounting of component A, B component and the C component of component A film layer, B component film layer and C component film layer be respectively 1～
99:20～80:20～80；Described component A includes that homopolymerisation polyethylene and block copolymerization polypropylene, described B component include that homopolymerization gathers
Ethylene, polyethylene copolymer and silane grafted polyethylene, described C component includes HOPP block copolymerization polypropylene.
