Abstract
The utility model relates to solar energy utilization, and specially relates to an improved solar cell back membrane, which belongs to the field of a new energy technology. The technology problem of unreasonable design in the prior art and other technology problems are solved. The improved solar cell back membrane comprises a sheet-shaped intermediate member layer, the improved solar cell back membrane is characterized in that two surfaces of the intermediate member layer are respectively provided with an acrylic acid layer formed by coating acrylic acid paint. Compared to the prior art, the improved solar cell back membrane is provided with the advantages as following: 1, the design is reasonable, little manufacture material is employed, and each performance index is greatly lifted; 2, good anti-ultraviolet performance, high weatherability, chemically-resistant performance, a good electrical insulating property, strong waterproof and fat-proof performance and high heat stability are provided; and 3, process and manufacture are easy, and the production cost is low.
Description
Technical field
The utility model belongs to technical field of new energies, relates to the solar energy utilization, especially relates to a kind of modified form solar battery back film.
Background technology
Solar panel is a laminated construction normally, mainly comprises surface layer of glass, EVA sealant, solar battery sheet, EVA sealant and solar battery back film.Wherein solar battery sheet is by two-layer EVA sealant sealed envelope.The main effect of solar battery back film is the overall mechanical strength that improves solar panel, can prevent that in addition water vapor permeable from sealant, influencing the useful life of battery sheet.
In order to improve the overall performance of notacoria, occurred in the prior art carrying out improved plan at notacoria in a large number.For example, Chinese patent literature discloses a kind of notacoria [application number: 200820133533] that is used for solar cell, it is characterized in that: it is five-layer structure, comprises the silicon titanizing film forming layer, basic unit, silicon titanizing film forming layer, fluorine-based rete and the silicon titanizing film forming layer that are laminated with successively together.This scheme has high-adhesion and has high-weatherability, chemical resistance, high electrical insulation properties, high water proofing property.
Although such scheme increases on the performance in every respect, the number of plies of whole notacoria is more, and structure is comparatively complicated, and manufacture difficulty is bigger, and becomes to produce the cost height.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, is easy to processing and manufacturing, and is stable and reliable for performance, the modified form solar battery back film of long service life.
For achieving the above object, the utility model has adopted following technical proposal: this modified form solar battery back film, comprise middle rete in the form of sheets, it is characterized in that the two sides of described middle rete is provided with and is respectively equipped with the acrylate layer that is formed by the acrylic coating coating.
Play the adhesion that increases PET and EVA when reaching 1 μ m after the acrylate layer thickness drying; It has effects such as good anti-UV, anti-water, anti-solvent, anti-weather when reaching 5 μ m after the acrylate layer thickness drying; It had good anti-UV when acrylate layer surpassed 10 μ m in coating, effects such as anti-water, anti-solvent, anti-weather.
In above-mentioned modified form solar battery back film, described middle rete is made by the PET material.
In above-mentioned modified form solar battery back film, the thickness of described acrylate layer is not less than 10 μ m.
Compared with prior art, the advantage of this modified form solar battery back film is: 1, reasonable in design, adopt less manufactured materials, and but significantly promoted every performance index.2, have good ultraviolet-resistent property, high-weatherability, chemical resistance, electrical insulation properties is good, water and oil-resistant is strong, the thermal stability height.3, be easy to processing and manufacturing, production cost is low.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, middle rete 1, acrylate layer 2.
Embodiment
As shown in Figure 1, the modified form solar battery back film comprises middle rete 1 in the form of sheets, it is characterized in that, the two sides of described middle rete 1 is provided with and is respectively equipped with the acrylate layer 2 that is formed by the acrylic coating coating.Middle rete 1 is made by the PET material.The thickness of acrylate layer 2 is not less than 10 μ m.
Play the adhesion that increases PET and EVA when reaching 1 μ m after the acrylate layer thickness drying; It has effects such as good anti-UV, anti-water, anti-solvent, anti-weather when reaching 5 μ m after the acrylate layer thickness drying; It had good anti-UV when acrylate layer surpassed 10 μ m in coating, effects such as anti-water, anti-solvent, anti-weather.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as middle rete 1, acrylate layer 2 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
Claims (3)
