Abstract
The utility model relates to a low-cost and high-performance solar energy composite back plate which is characterized in that the back plate comprises, from the top to the bottom in turn, a first thermoplastic polymer layer (1), a glass fiber cloth layer (2), a second thermoplastic polymer layer (3) and an adhesion layer (4). A composite structure of the two thermoplastic polymer layers and the glass fiber cloth is adopted by the back plate so that a cost is reduced, and high-strength, high heat resistance and high insulation performances are given to the solar energy back plate. In order to improve an adhesion performance of the thermoplastic polymer and the glass fiber cloth, the glass fiber cloth is pretreated by the thermoplastic polymer in an infiltration way. The adhesion layer adopts a transparent or white EVA or PE so that the adhesion to the upper layer is improved, and a light reflectivity can be improved and a photoelectric conversion efficiency of an assembly is strengthened with the existence of the white EVA. Therefore, the solar energy composite back plate has advantages of being high in mechanical strength, great in weather resistance, great in adhesion performance between the layers and low in cost.
Description
Technical field
The utility model relates to a kind of solar energy backboard, relates in particular to a kind of low cost, the compound backboard of high performance solar energy, 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.Tradition solar energy backboard generally adopts fluorine material and PET(PETG) composite construction, when guaranteeing solar energy backboard weatherability, but exist cost height, layer with layer between problems such as caking property is not good.And on the market the new compound backboard of releasing of some novel solar energy also in various degree have that mechanical strength is low, weatherability difference or the too high defective of cost.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and preferable low cost, the compound backboard of high performance solar energy of caking property between a kind of mechanical strength height, good weatherability, layer and the layer is provided.
The purpose of this utility model is achieved in that
A kind of low cost, the compound backboard of high performance solar energy is characterized in that it comprises first thermoplastic polymer layer, glass layer of cloth, second thermoplastic polymer layer and tack coat from top to bottom successively.
As a kind of preferred, described first thermoplastic polymer layer and second thermoplastic polymer layer's material is the plastic alloy of PP, PE, PC, PA, PET, PBT, PPE, PPS, above two kinds or two or more materials.
As a kind of preferred, described first thermoplastic polymer layer and second thermoplastic polymer layer's thickness is 1 ~ 500 μ m.
As a kind of preferred, the thickness of described glass layer of cloth is 1 ~ 500 μ m.
As a kind of preferred, the glass cloth of described glass layer of cloth is that alkali-free glass is made.
As a kind of preferred, described tack coat adopts cross-linking type EVA or PE to make
As a kind of preferred, the color of described cross-linking type EVA or PE is white or transparent.
As a kind of preferred, the thickness of described tack coat is 1 ~ 1000 μ m.
Compared with prior art, the beneficial effects of the utility model are:
The utility model when reducing cost, is given solar energy backboard high strength, high-fire resistance and high-insulativity owing to adopt the composite construction of two layers of thermoplastic polymer and glass cloth.In order to improve the caking property of thermoplastic polymer and glass cloth, glass cloth adopts thermoplastic polymer to soak in advance, and tack coat adopts transparent or white EVA or PE, is promoting and the close-burning while of upper strata, the existence of white EVA can improve light reflectance, strengthens the electricity conversion of assembly.Therefore the compound backboard of this solar energy have mechanical strength height, good weatherability, layer with layer between advantage such as preferable, the low cost of caking property.
