Description
Technical field
The present invention relates to photovoltaic glued membrane technical field, particularly a kind of eutectic refers to the compound white photovoltaic glued membranes of tri- layers of EVA
Preparation method.
Background technology
Nearly ten years, because technological progress and cost are cheap, the development of China's photovoltaic industry is very swift and violent, from 2008 with
Come, yield and the output value exceed the photovoltaics such as Germany, Japan power and occupy the first in the world.But solar cell photoelectric converts at present
Effect is difficult to improve, and between maintaining 18%~19% always, how to improve the photoelectric transformation efficiency of photovoltaic cell turns into the world
The important references of photovoltaic industry focus of attention and national governments' New Energy Industry layout.Present photoelectric transformation efficiency is from theory
Also there is a big difference for the generating efficiency 26.8%~30% of calculating, and the source of these losses is many, including battery
The blank at interval and cell piece and module edge between piece.
Solar photovoltaic assembly basic structure is formed by 5 layers from top to bottom：Upper strata high-transparency Guang volt Bo Li ﹑ upper stratas EVA glue
Mo ﹑ electricity Chi Pian ﹑ lower floor's EVA Jiao Mo ﹑ photovoltaic backs or lower floor's photovoltaic glass.Due to this structure, sunshine is incident from glass, warp
Upper strata EVA adhesive film is crossed, cell piece is reached and realizes opto-electronic conversion, interval and cell piece and component side of the sunshine between cell piece
There is greater loss in the blank space of edge, if bottom is photovoltaic glass, then sunshine can be projected directly, if photovoltaic back
Plate, because backboard reflectivity is not high, about 70-80%, the sunshine for thus having 20-30% is lost.Therefore, high reflecting rate
White EVA adhesive film preparation and application just turn into solar energy industry circle research focus.But go deep into research, gas
Pao ﹑ folds and the problem of white of overflowing, gradually display.Because photovoltaic module needs high temperature lamination ability curing molding, and it was laminated
In order to solve the generation of bubble, it is necessary to vacuumize in journey, under the double action of air pressure and internal stress, white EVA adhesive film occurs
Fold, and easily overflow in vain on cell piece and busbar, the attractive in appearance of photovoltaic module is so not only have impact on, and reduce work(
Rate.So solve the problems, such as Qi Pao ﹑ folds and overflow white just to turn into the task of top priority.
The content of the invention
The technical problem to be solved in the invention is that a kind of hot melt mobility is low and the eutectic of corrugationless and white risk of overflowing refers to
The preparation method of the compound white photovoltaic glued membranes of tri- layers of EVA.
In order to solve the above technical problems, the eutectic of the present invention refers to the preparation method of the compound white photovoltaic glued membranes of tri- layers of EVA, will
Eutectic refers to ethylene-vinyl acetate copolymer, white filler, antioxidant and crosslinking agent and silane coupler be sufficiently mixed after add and squeeze
Go out machine hopper and prepare white EVA layer；Eutectic is referred into ethylene-vinyl acetate copolymer, antioxidant and crosslinking agent and silane coupler
Extruder hopper is added after being sufficiently mixed and prepares upper and lower transparent EVA layer；Melting coextrusion is carried out, each region of extruder, die head
80~90 DEG C of temperature humidity, is extruded through co-extrusion die head, is cooled down by way of casting roller, then is shaped after thickness measuring, embossing procedure, most
Trimming, winding again afterwards, packaging and storage.
Further, the antioxidant includes primary antioxidant and auxiliary anti-oxidant, wherein, the main antioxygen base is β-(3,5-
Di-tert-butyl-hydroxy phenyl) propionic acid octadecanol ester；The auxiliary anti-oxidant is three (4- nonyl phenols) phosphite esters and/or Asia
Tricresyl phosphate (2,4- di-tert-butyl-phenyls) ester.
Further, the auxiliary anti-oxidant is three (4- nonyl phenols) phosphite esters and (2, the 4- di-t-butyls of phosphorous acid three
Phenyl) ester compound.
Further, the crosslinking agent includes crosslinking and curing agent and assistant crosslinking agent, wherein, the crosslinking and curing agent includes
Machine peroxide and/or azo-compound, the organic peroxide are included for dicumyl peroxide, di-tert-butyl peroxide
Thing, di-isopropylbenzene hydroperoxide, the di-t-butyl hexane peroxide of 2,5- dimethyl -2,5,4,4- bis- (t-amyl peroxy) valeric acid are just
Butyl ester, the one or more in the peroxidating 2- ethylhexyl carbonates tert-butyl ester, 3,3- bis- (t-butyl peroxy) ethyl butyrate；Institute
State assistant crosslinking agent include Triallyl isocyanurate, TAC, trimethylol-propane trimethacrylate,
One or more mixing in diethyleneglycol dimethacrylate.
Further, the silane coupler is VTES, vinyltrimethoxy silane, vinyl
In three tert-butyl peroxide silane, vinyltriacetoxy silane, vinyl three ('beta '-methoxy ethyoxyl) silane at least
It is a kind of.
Further, the white filler, is titanium dioxide, white carbon, the white inorganic particle of barium sulfate.
Further, the white filler surface is handled by Coated with Organic Matter, is processed into the EVA of 30-70% concentration
Used after white master batch.
Further, the gross thickness that the eutectic refers to the compound white photovoltaic glued membranes of EVA is 350-750 μm.
Using above-mentioned rear method, products application produced by the present invention is in extensive range, and reflecting rate reaches more than 90%, Neng Gouti
The photoelectric transformation efficiency of high photovoltaic module, and can eliminate simultaneously bubble and it is hidden split, fold and the white phenomenon of overflowing.In addition, tool
There are following characteristics：
1st, EVA adhesive film hot melt viscosity can be greatly improved by referring to EVA micelles from eutectic, reduced it and heated mobility, reduce
Its fold and white risk of overflowing in vacuum is laminated.
2nd, EVA compound cutans are produced from three-layer co-extruded method, upper and lower two layers is transparent EVA layer, and intermediate layer is white
EVA layer.Because tunica albuginea is by two layers of transparent plastic mulching, its fold and the white wind that overflows in vacuum is laminated further is reduced
Danger, while the thickness of tunica albuginea is also reduced, the dosage of titanium dioxide is reduced on the basis of reflecting rate is ensured, reduces and is manufactured into
This.Tunica albuginea, which is caught in the middle, simultaneously is not involved in bonding with glass or backboard, and hyaline membrane is again without filling white filler, so guarantor
Hold higher cohesive force.
