As preferably, described thin layer is pet film, and the thickness of described thin layer is 100-400 micron.
As preferably, described priming coat is class adhesive for polyurethane, and the thickness of described priming coat is 5-30 micron.
As preferably, described coat is that the molecule of polytetrafluoroethylene or Kynoar is dispersed in the coating coating forming in solvent together with base resin.
As preferably, the thickness of described coat is 10-40 micron.
The invention also discloses a kind of method of manufacturing above-mentioned heterogeneous two-sided fluorine-containing type solar cell backboard, comprise the steps:
A. the one side at thin layer is coated with last layer adhesive, after gluing completes, is dried;
B. compound one deck fluorine rete on the adhesive of steps A, carries out rolling after compound, forms semi-finished product;
C. step B gained semi-finished product are carried out to precuring;
D. the another side of the half-finished thin layer after above-mentioned solidify is smeared bottom-coating, forms priming coat, is dried after smearing end;
E. on priming coat, be coated with fluoro-containing coating, coating is dried after finishing, rolling, cutting edge, go to give up, and finally carries out product inspection, packing shipment.
Beneficial effect: the present invention combines traditional compound and application type backboard, and production cost is low, slows down aging speed, has improved the Acceptable life of backboard, has improved the adhesion strength with EVA backboard glued membrane simultaneously.
Accompanying drawing explanation
Fig. 1 is the sectional structure chart of backboard of the present invention.
Fig. 2 is the production technological process of a face of the present invention.
Fig. 3 is the production technological process of another face of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
A kind of heterogeneous two-sided fluorine-containing type solar cell backboard as shown in Figure 1, backboard comprises the fluorine rete 1 connecting successively, adhesive layer 2, thin layer 3, priming coat 4 and coat 5, wherein fluorine rete is polyvinylidene fluoride film or pvf film, the thickness of fluorine rete is 20-30 micron, adhesive layer is polyurethane bicomponent adhesive, the thickness of adhesive layer is 5-30 micron, thin layer is pet film, the thickness of thin layer is 100-400 micron, priming coat is class adhesive for polyurethane, the thickness of priming coat is 5-30 micron, coat is that the molecule of polytetrafluoroethylene or Kynoar is dispersed in the coating coating forming in solvent together with base resin, the thickness of coat is 10-40 micron.
The method of the above-mentioned heterogeneous two-sided fluorine-containing type solar cell backboard of manufacture as shown in Figures 2 and 3, comprises the steps:
A. the one side at thin layer 3 is coated with last layer adhesive, after gluing completes, is dried;
B. compound one deck fluorine rete 1 on the adhesive of steps A, carries out rolling after compound, forms semi-finished product;
C. step B gained semi-finished product are carried out to precuring;
D. the another side of the half-finished thin layer 3 after above-mentioned solidify is smeared bottom-coating, forms priming coat 4, is dried after smearing end;
E. on priming coat, be coated with fluoro-containing coating, coating is dried after finishing, rolling, cutting edge, go to give up, and finally carries out product inspection, packing shipment.
The present invention has following outstanding advantages:
A. PVDF or PVF thin layer are placed on to outside, accept the destruction of external environment, coat is placed on to innermost layer, to improve the adhesion strength with EVA glued membrane;
B. application type layer contains fluorine atom, weatherability aspect is better than PEVA film certainly, in addition coated side has a large amount of tiny pin holes, the interior heat that can guarantee cell panel is outwards discharged, in addition because EVA glued membrane self thermal stability causes after aging again crosslinked and decompose, the little molecule meeting corrosion cell plate producing, gets rid of therefore the larger permeability of coated side can guarantee these little molecules;
C. in order to meet the requirement of 25 years useful life, only have at present KPK type composite back plate energy up to standard, and PEVA film main component is polyethylene in KPE backboard, ultraviolet ageing speed is fast, PET protection duration to internal layer is shorter, this has directly caused the useful life of backboard short, yet the destruction that fluorine-containing coating to a certain extent can block ultraviolet has been slowed down rate of ageing;
D. the whole world constantly reduction storm make the survival ability of photovoltaic industry more and more lower, become for survival basic meeting price under the prerequisite of instructions for use, and coat is lower compared with PVDF film price.
