Description
Technical field
The present invention relates to film applications, more particularly to a kind of solar energy backboard Obstruct membrane and preparation method thereof.
Background technology
Solar energy backboard with Obstruct membrane (abbreviation solar energy backboard membrane) be located at solar panel the back side, play support and
The effect of cell piece is protected, this requires that backboard membrane has reliable insulating properties, water vapor barrier property and hydrolysis aging.At present
The common backboard of in the market is usually TPT or TPE composite constructions, and wherein P layers refers to the PET film layer played a supporting role, and PET
It is a kind of medium barrier material, the barrier to steam and oxygen is not good, therefore, develop a kind of solar energy back of the body of high barrier
Plate film has important realistic meaning to the life-span for improving solar cell.
The content of the invention
Poor in order to solve the problems, such as existing solar energy backboard membrane water vapor barrier property, the present invention provides a kind of solar energy backboard
With Obstruct membrane and preparation method thereof.The solar energy backboard that the present invention is provided Obstruct membrane has water vapor barrier property higher and water-fast
Xie Xing.The preparation method process is simple of the solar energy backboard Obstruct membrane that the present invention is provided, it is adaptable to mass produce.
In order to solve the above-mentioned technical problem, the present invention uses following technical proposals：
The present invention provides a kind of solar energy backboard Obstruct membrane, and the Obstruct membrane is ABA three-deckers, in the Obstruct membrane
A layers material be PEN (PEN)；The raw material of described B layers by polyester resin, nanometer inorganic filler,
