Description
Technical field
The present invention relates to technical field of solar batteries, particularly relate to a kind of PEN one side coating back plate and preparation method thereof.
Background technology
Solar energy insulating back panel is generally made up of five-layer structure, enhancement layer and be compound in the outer weathering layer on enhancement layer two sides and interior weathering layer respectively by tack coat, is normally connected by binding agent between enhancement layer and two weathering layers.Usually, the PVDF material of outer time layer to be thickness be 25um, the PET of middle reinforced layer to be thickness be 250um, the thickness of interior time layer is 50 ~ 60um, the polyurethanes glue of tack coat to be thickness be 10um.
There is following major issue in current solar energy backboard: one, in PVDF produces, film itself have pore unavoidably or impurity causes steam from the bad intrusion in the surface of PVDF backboard, and polyurethane adhesive is subject to easily being hydrolyzed after steam is invaded and harassed, thus the pet layer corroded further in the middle of backboard, PET material itself to be easily hydrolyzed water is more responsive, thus greatly reduces the useful life of backboard; Its two, manufacture complex type solar backboard with polyurethanes glue, cost is relatively high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of PEN one side coating back plate and preparation method thereof, can solve the insulating back panel hydrolysis caused because of the water-fast and steam performance that PET is lower in prior art and destroys and use adhesive between enhancement layer and outer time layer thus increase the problems such as cost.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of PEN one side coating back plate, comprise: fluororine-carbon coating, PEN material layer, polyurethane drying adhesive layer and PE film, the 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 a preferred embodiment of the present invention, the thickness of described fluororine-carbon coating is 20 μm.
In a preferred embodiment of the present invention, the thickness of described PEN material layer is 250 μm.
In a preferred embodiment of the present invention, the thickness of described polyurethane drying adhesive layer is 10 μm.
In a preferred embodiment of the present invention, the thickness of described PE film is 50 μm.
For solving the problems of the technologies described above, another technical solution used in the present invention is: the preparation method providing a kind of PEN one side coating back plate, and preparation method is: be directly coated on by described fluororine-carbon coating on a side of surface treated described PEN material layer; Then surface treatment is carried out in another side of PEN material layer, surface coating polyurethane adhesive after treatment also toasts; After glue-line baking-curing, the hot pressing of PE film is compound in the another side of PEN material layer, obtains PEN one side coating back plate.
The invention has the beneficial effects as follows: the preparation method of a kind of PEN of the present invention one side coating back plate is simple and easy to do, is directly coated on by fluororine-carbon coating on PEN material, do not need to use adhesive, make processing more convenient, and efficiency is high, cost is lower.Compared with prior art, prepared PEN one side coating back plate also 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, it is 3.5 ~ 4 times of PET, greatly improve the resistant to hydrolysis ability of solar energy backboard, solar energy insulating back panel is not by moist impact, is particularly suitable for the solar energy project that hot and humid area uses.
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.
