Abstract
The utility model relates to a high strength, high insulation and high reflectivity solar energy composite backplane which is characterized in that the solar energy composite backplane successively comprises, from the top to the bottom, a weather-resistant barrier layer (1), an insulation layer (2) and an adhesion layer (4). The base material of the insulation layer (2) is PO which is provided with a layer of glass fabric (3) internally. With the help of the composite structure of the PO and the glass fabric, the insulation layer is configured to realize the high strength and high insulation performance of the backplane. A lower white EVA layer helps to improve the light reflectivity and a photoelectric converting efficiency of a battery piece. The structure of the PO and the EVA provides the high adhesion performance between the layers so that a peel strength between the layers of the backplane is strengthened. Therefore, the solar energy composite backplane has advantages of being high in strength, high in insulation and high in reflectivity.
Description
Technical field
The utility model relates to a kind of solar energy backboard, relates in particular to the compound backboard of solar energy of a kind of high strength, high insulation, high reflectance, belongs to the photovoltaic technology field.
Background technology
The solar energy backboard is intended to battery sheet and whole assembly are played the effect of support, protection, and is therefore very strict to its every performance requirement.Traditional solar energy backboard generally all is structures such as TPT, TPE, and materials such as fluorine film, PET have but caused the adhesive property between backsheet layer and the layer not good when having guaranteed performance such as backboard is weather-proof, obstruct, cause interlaminar strength a little less than; And the reflectivity that this structure is lower has also limited its application to a certain extent.And occur on the market some be modification PA such as each layer of AAA(), each layer of PET(be PET) the compound backboard of type also all exists defectives such as the weak or weatherability difference of mechanical strength, these all make photovoltaic module can extremely be seriously influenced under severe environmental conditions, even cause scrapping of whole assembly.Therefore the compound backboard of solar energy of seeking a kind of high strength, high insulation, high reflectance is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the compound backboard of solar energy of a kind of high strength, high insulation, high reflectance is provided.
The purpose of this utility model is achieved in that
The compound backboard of solar energy of a kind of high strength, high insulation, high reflectance, its feature is being that it comprises weather-proof barrier layer, insulating barrier and tack coat from top to bottom successively, the base material of described insulating barrier is PO, is provided with layer of glass fiber fabric in the described PO.
As a kind of preferred, the base material of described weather-proof barrier layer is the PET film, and the outer surface of described PET film is coated with one deck PVF, PVDF or fluorocarbon coating.
As a kind of preferred, the preferred 10-300 μ of the thickness of described PO m, the preferred 5-300 μ of the thickness of described glass cloth m.
As a kind of preferred, described tack coat adopts cross-linking type white EVA, and the thickness of described tack coat is preferably 10-600 μ m.
Compared with prior art, the beneficial effects of the utility model are:
Insulating barrier of the present utility model has been realized high strength and the high insulating property of backboard by the composite construction of PO and glass cloth; And the white EVA of lower floor is conducive to improve light reflectance, promotes the electricity conversion of battery sheet, and the structure of PO and EVA is also given the adhesive property of height between layer and the layer, strengthens the interlaminar strength of backboard.Therefore the compound backboard of this solar energy has the advantage of high strength, high insulation, high reflectance.
