Abstract
The utility model discloses a kind of flat PEVA film of photovoltaic back, including EVA film layer and PE film layer, PE film layer is positioned at the outside of EVA film layer, and the surface of described PE film layer is provided with antioxygen layer, is provided with UV absorbed layer, titanium dioxide layer and UV light stabilized zone between described antioxygen layer and PE film layer.This one photovoltaic back is reasonable in design with flat PEVA film, there is good resistance to oxidation function, economic and environment-friendly, can be used in the E layer in KPE photovoltaic back structure, play the function of backboard and EVA bonding when cell package, compare traditional PE film, itself and EVA, it is more preferable with the adhesive property of PU glue, and weatherability is more preferable, is suitable for being widely popularized.
Description
[technical field]
This utility model relates to a kind of thin film, particularly to a kind of photovoltaic back with flat PEVA film.
[background technology]
At present, the use of PE membrane material is very universal, but, the thin-film material such as traditional PE film in use, resistance to oxidation
Poor-performing, and can not well be used for the E layer in KPE photovoltaic back structure, itself and EVA film, it is viscous with PU glue
Knot poor-performing, uses also the most uneconomical, to this end, it is proposed that a kind of photovoltaic back is with flat PEVA film.
[utility model content]
Main purpose of the present utility model is to provide a kind of flat PEVA film of photovoltaic back, and this one photovoltaic back is with flat
PEVA film is reasonable in design, has good resistance to oxidation function, economic and environment-friendly, it is possible to the E layer in KPE photovoltaic back structure,
Play the function of backboard and EVA bonding when cell package, compare traditional PE film, itself and EVA, itself and the caking property of PU glue
Can more preferably, weatherability is more preferable, is suitable for being widely popularized, can effectively solve the problem in background technology.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of photovoltaic back is with flat PEVA film, and including EVA film layer and PE film layer, PE film layer is positioned at the outside of EVA film layer, institute
The surface stating PE film layer is provided with antioxygen layer, is provided with UV absorbed layer, titanium dioxide layer and UV light between described antioxygen layer and PE film layer
Stabilized zone.
Further, UV absorbed layer is specially UV absorbent, and UV light stabilized zone is specially UV light stabilizer.
Further, described antioxygen layer is antioxidant.
Compared with prior art, this utility model has the advantages that this one photovoltaic back sets with flat PEVA film
Meter is reasonable, by arranging EVA film layer, UV absorbed layer, PE film layer, UV light stabilized zone and antioxygen layer, it is possible to ensure this one photovoltaic
The backboard utilization benefit of flat PEVA film so that this thin film has good resistance to oxidation function, economic and environment-friendly, it is possible to for KPE
E layer in photovoltaic back structure, plays the function of backboard and EVA bonding, compares traditional PE film when cell package, its with
EVA, it is more preferable with the adhesive property of PU glue, and weatherability is more preferable, is suitable for being widely popularized.
[accompanying drawing explanation]
Fig. 1 is a kind of photovoltaic back of this utility model overall structure schematic diagram with flat PEVA film.
In figure: 1, EVA film layer 3, PE film layer；5, antioxygen layer.
[detailed description of the invention]
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below
In conjunction with detailed description of the invention, this utility model is expanded on further.
As it is shown in figure 1, a kind of photovoltaic back is with flat PEVA film, including EVA film layer 1 and PE film layer 3, PE film layer 3 is positioned at EVA
The outside of film layer 1, the surface of described PE film layer 3 is provided with antioxygen layer 5, is provided with UV and absorbs between described antioxygen layer 5 and PE film layer 3
Layer, titanium dioxide layer and UV light stabilized zone.
Wherein, UV absorbed layer is specially UV absorbent, and UV light stabilized zone is specially UV light stabilizer.
Wherein, described antioxygen layer 5 is antioxidant.
It should be noted that this utility model is a kind of flat PEVA film of photovoltaic back, this PEVA thin film by EVA film layer 1,
PE film layer 3, antioxygen layer 5 and UV absorbed layer and UV light stabilized zone composition, it is possible to the E layer in KPE photovoltaic back structure,
Play the function of backboard and EVA bonding during cell package, compare traditional PE film, itself and EVA, itself and the adhesive property of PU glue
More preferably, weatherability is more preferable, and utilization benefit is the highest.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model
Claimed scope is defined by appending claims and equivalent thereof.
