Abstract
The utility model discloses a coated solar battery back panel. One surface of a base material is coated by a weather resistant layer; the other surface of the base material is coated by an adhesive layer, a second weather resistant layer and a protective layer, wherein the second weather resistant layer is positioned between the adhesive layer and the protective layer; and the protective layer is positioned at the outer surface of the second weather resistant layer. The defects that stratification occurs between one weather resistant layer and an EVA (Ethylene-Vinyl Acetate) layer along with the prolonging of the use time of a battery, and the weather resistant layers fall off from the base material are overcome, so that the coated solar battery back panel has excellent weather resistance and long-time use stability, and the service life of a solar battery pack is ensured.

Background technology
As the green replacement scheme of traditional production method of electric energy, photovoltaic cell component is used to utilize solar energy to produce electric energy.Photovoltaic cell component is to be assembled by various semiconductor elements, thereby must be protected to reduce environmental activity such as moisture, oxygen and ultraviolet impact and destruction.Photovoltaic cell component generally adopts glass, cell silicon chip, EVA, back veneer material hot pressing to form; therefore, the backboard that has good electric insulating quality, bond strength between layers, weather resisteant, ultraviolet-resistent property and moisture barrier property is being brought into play important protective effect in photovoltaic cell component.
Usually, backboard is compound or be applied on polyester (PET) base material and form by the fluorinated polymer material with weatherability, for application type backboard product, prolongation along with service time of battery, anti-marquis's coating comes off from polyester easily, layering occurs between anti-marquis's coating and the EVA layer, affect the service life of battery.
The utility model content
The technical problems to be solved in the utility model is the weak point that exists for prior art, and a kind of application type solar cell backboard with excellent weather resistance and long-term stability in use is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of application type solar cell backboard; it is at coated on one side first layer of anti-marquis of base material, at the another side of base material successively coat binding layer, the second weathering layer and protective layer, wherein; the second weathering layer is between adhesive layer and protective layer, and protective layer is positioned at the outer surface of the second weathering layer.
In the above-mentioned backboard, described the first weathering layer, the second weathering layer be in polyfluoroethylene resin, polyvinylidene fluoride resin, polyflon, the daiflon one or more mixture coating film-forming and obtain, the thickness of the first weathering layer, the second weathering layer is 0.01-0.03mm; The thickness of described the first weathering layer, the second weathering layer can be identical, also can be different; The layer of anti-marquis has excellent weatherability, the service life of having improved solar cell backboard.
In the above-mentioned backboard, described adhesive layer is macromolecule resin coating film-forming and obtaining, and the thickness of adhesive layer is 0.001-0.02mm; Macromolecule resin can be selected from two-component polyurethane adhesive, acrylic ester adhesive, polyvinyl acetate adhesive or epobond epoxyn.Has simultaneously excellent adhesive fastness between adhesive layer and base material and the second layer of anti-marquis; improved on the one hand the protectiveness of the layer of anti-marquis to base material; overcome on the other hand the disadvantage that anti-marquis's coating comes off from base material easily, improved weatherability and the long-term stability of using of solar cell backboard.
In the above-mentioned backboard; described protective layer is macromolecule resin coating film-forming and obtaining; the thickness of protective layer is 0.05-0.03mm; protective layer is positioned at the outer surface of the second weathering layer; has simultaneously excellent adhesive fastness between it and EVA and the Nai Hou layer; can improve the adhesive fastness between solar energy backboard and the EVA, overcome lamination between anti-marquis's coating of occurring along with the prolongation of service time of battery and the EVA layer, guarantee the service life of solar module.
Compared with prior art; the utility model is because each coating has the adhesive fastness that has simultaneously excellence between the EVA glued membrane in excellent adhesive fastness, protective layer and the battery component each other; overcome lamination between anti-marquis's coating of occurring along with the prolongation of service time of battery and the EVA layer; and the drawback that comes off from base material of anti-marquis's coating; make product have excellent weather resisteant and long-term stability in use, guaranteed the service life of solar module.
