Abstract
The utility model discloses a PEN single-sided coating backplane. The PEN single-sided coating backplane includes a fluorocarbon coating, a PEN material layer, a polyurethane dry glue layer and a PE membrane; one side of the PEN material layer is bonded with the PE membrane through the polyurethane dry glue layer; and the other side of the PEN material layer is directly bonded with the fluorocarbon coating. According to the PEN single-sided coating backplane of the utility model, PEN materials are adopted, and therefore, hydrolysis resistance capability and mechanical strength of the solar backplane can be greatly enhanced, and a service life of 25 years can be guaranteed for a solar assembly; at the same time, the fluorocarbon coating is directly coated on the PEN materials without an adhesive required, and therefore, processing can be more convenient, and efficiency is high, and cost is lower.
Description
Technical field
The utility model relates to technical field of solar batteries, particularly relates to a kind of PEN one side coating back plate.
Background technology
Solar energy insulating back panel is generally comprised of five-layer structure, and enhancement layer and be compound in respectively outer weathering layer and the interior weathering layer on enhancement layer two sides by tack coat normally connects by binding agent between enhancement layer and two weathering layers.Conventionally, outer time layer is that thickness is the PVDF material of 25um, and middle reinforced layer is that thickness is the PET of 250um, and the thickness of interior time layer is 50～60um, and tack coat is that thickness is the polyurethanes glue of 10um.
There is following major issue in solar energy backboard at present: one, in PVDF produces, film itself have unavoidably pore or impurity causes steam from the bad intrusion in the surface backboard of PVDF, and polyurethane adhesive is subject to after steam is invaded and harassed being easily hydrolyzed, thereby further corrode the pet layer in the middle of backboard, PET material itself is to more responsive easy hydrolysis of water, thus the useful life of greatly reducing backboard; Its two, with polyurethanes glue, manufacture complex type solar backboard, cost is relatively high.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of PEN one side coating back plate, thereby can solve in prior art, because the lower insulating back panel water-fast and that steam performance causes of PET is hydrolyzed between destruction and enhancement layer and outer time layer, uses adhesive to increase the problems such as cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of PEN one side coating back plate is provided, it is characterized in that, comprise: fluororine-carbon coating, PEN material layer, polyurethane drying adhesive layer and PE film, a side of described PEN material layer is bonded together by polyurethane drying adhesive layer and PE film; The opposite side of described PEN material layer directly bonds with described fluororine-carbon coating.
In preferred embodiment of the utility model, the thickness of described fluororine-carbon coating is 20 μ m.
In preferred embodiment of the utility model, the thickness of described PEN material layer is 250 μ m.
In preferred embodiment of the utility model, the thickness of described polyurethane drying adhesive layer is 10 μ m.
In preferred embodiment of the utility model, the thickness of described PE film is 50 μ m.
The beneficial effects of the utility model are: a kind of PEN one side of the utility model coating back plate, and compared with prior art, tool has the following advantages:
1) thermal endurance of PEN material, barrier properties for gases, radiation hardness ability, resistance to water and water-fast barrier are better, especially resistance to water and water-fast barrier, 3.5～4 times of PET, greatly promoted the resistant to hydrolysis ability of solar energy backboard, solar energy insulating back panel is not subject to moist impact, is particularly suitable for the solar energy project that hot and humid area is used.
2) PEN material also has good chemical stability, UV resistant and physical property, and solar energy insulating back panel prepared therefrom can prevent ultraviolet irradiation, and mechanical strength is also much improved, and can guarantee solar power generation assembly useful life of 25 years.
3) outer weathering layer adopts fluororine-carbon coating, plays the effect of protection backboard, shielding of ultraviolet and isolation steam.
4) fluororine-carbon coating is directly coated on PEN material, does not need to use adhesive, makes to process more convenient, and efficiency is high, cost is lower.
