Abstract
A composite film of a back plate comprises an ETFE (ethyl tetra fluoro ethylene) film, a first glue layer, a PET (polyethylene terephthalate) plate, a second glue layer and a PE (polyethylene) film. The composite film is characterized in that the ETFE film is adhered with the PET plate through the first glue layer, and the PE film is adhered with the PET plate through the second glue layer. The composite film of the back plate for a solar battery has the advantages that the weather resistance and the chemical corrosion resistance of the composite film of the back plate for the solar battery are enhanced by the aid of the ETFE film and the PE film, battery pieces can be more effectively protected, and the service life of a solar module is prolonged.
Description
Technical field
The utility model relates to a kind of rear panel compound film.
Background technology
The generating of solar module source is the battery sheet in the assembly, will decay rapidly if the battery sheet is not carried out its generated output of packaging protection, thereby the use value of losing, so the life-span of encapsulating material directly influence the life-span of battery component.Develop a series of encapsulating material for reaching permanent instructions for use people, using more at present is compound film for solar battery rear board, though can satisfy the instructions for use of solar cell, its complicated process of preparation, cost is higher.
Compound film for solar battery rear board is big owing to hot strength, modulus of elasticity is high, impact strength is big, cold-resistant good heat resistance, electrical insulating property are good etc. is widely used in many fields such as industry, civilian, agricultural, and electron trade is higher to its requirement, requires it to have higher hardness; More wear-resistant, scratch resistance is hindered; Pollution resistance is stronger, and now the compound film for solar battery rear board on the market to exist hardness lower, easy to wear; Be prone to scratch, shortcomings such as pollution resistance difference.
The utility model content
The utility model technical problem to be solved be to provide a kind of barrier property good, prolong the solar module rear panel compound film in useful life.
1, a kind of rear panel compound film is characterized in that: comprise ETFE film, first glue layer, PET plate, second glue layer and PE film, ETFE film and PET plate are bonding through first glue layer, and PE film and PET plate are bonding through second glue layer.
Preferably, described ETFE film thickness is 0.05mm-0.25mm.
Preferably, the described first glue layer thickness is 0.005mm-0.02mm.
Preferably, described PET plate thickness is 0.5mm-2.5mm.
Preferably, the described second glue layer thickness is 0.005mm-0.02mm.
Preferably, described PE film thickness is 0.05mm-0.25mm.
A kind of compound film for solar battery rear board beneficial effect of the utility model is:
Being provided with ETFE film and PE film strengthens the weatherability of compound film for solar battery rear board and chemical corrosivity; Can better protect the battery sheet, prolong the useful life of solar module.
Description of drawings
Fig. 1 is the sectional view of the utility model.
Among the figure: 1-the one ETFE film, 2-first glue layer, 3-PET plate, 4-second glue layer, 5-PE film.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further, but the protection range of the utility model is not limited to this.
