Abstract
A steam-proof coating rear panel belongs to the technical field of rear panels of solar-cell panels. The steam-proof coating rear panel comprises a base layer aluminum plate, a first polyethylene terephthalate (PET) layer and a second PET layer, wherein the first PET layer and the second PET layer are respectively arranged on both sides of the base aluminum plate in matched mode, the first PET layer and the second PET layer are formed by compositing, and outer surfaces of the first PET layer and the second PET layer are coated with coatings containing fluorine. Two sides of the base aluminum plate is provided with PET layers which are coated with coatings containing fluorine, thereby effectively reducing steam transmissivity of products, enhancing loading capacity and heat conduction performance of the products, and enabling an assembly to be safe to use.
Description
Technical field
The utility model belongs to the solar module technical field, is specifically related to the anti-aqueous vapor coating backboard of a kind of low moisture permeability, scope of application length.
Background technology
At present, the coating backboard is widely used in the solar module industry.A lot of solar module coating or overlay film type backboard moisture permeability influence the serviceability and the useful life of black box up to about 20% on the market.
The utility model content
At the above-mentioned problems in the prior art, the purpose of this utility model is to provide the anti-aqueous vapor coating backboard of a kind of low moisture permeability, scope of application length.
Described a kind of anti-aqueous vapor coating backboard, it is characterized in that comprising basic unit's aluminium sheet, and be equipped with respectively on basic unit aluminium sheet two sides that the outer surface of described first pet layer and second pet layer scribbles one deck fluorine-containing coat respectively by first pet layer and second pet layer that is composited.
Described a kind of anti-aqueous vapor coating backboard is characterized in that described basic unit aluminium plate thickness is 20-30 μ m.
Described a kind of anti-aqueous vapor coating backboard is characterized in that the described first pet layer thickness is 120-130 μ m.
Described a kind of anti-aqueous vapor coating backboard is characterized in that the described second pet layer thickness is 70-80 μ m.
Described a kind of anti-aqueous vapor coating backboard is characterized in that described fluoro-containing coating layer thickness is 20-25 μ m.
Described a kind of anti-aqueous vapor coating backboard is characterized in that described basic unit aluminium plate thickness is 25 μ m.
Described a kind of anti-aqueous vapor coating backboard is characterized in that the described first pet layer thickness is 125 μ m.
Described a kind of anti-aqueous vapor coating backboard is characterized in that the described second pet layer degree is 75 μ m.
Above-mentioned a kind of anti-aqueous vapor coating backboard comprises basic unit's aluminium sheet, and is equipped with respectively on basic unit aluminium sheet two sides by first pet layer and second pet layer that is composited, and the outer surface of described first pet layer and second pet layer scribbles one deck fluorine-containing coat respectively.The utility model can effectively reduce the moisture permeability of product by scribble the pet layer of fluorine-containing coat in the two surface recombination settings of basic unit's aluminium sheet, strengthens the bearing capacity and the heat-conductive characteristic of product, thereby guarantees the safe in utilization of assembly.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-basic unit aluminium sheet, 2-first pet layer, 3-second pet layer, 4-fluoro-containing coating layer.
Embodiment
The utility model will be further described below in conjunction with Figure of description:
A kind of anti-aqueous vapor coating backboard as shown in Figure 1, comprise basic unit's aluminium sheet 1, and be equipped with respectively on basic unit's aluminium sheet 1 two sides that the outer surface of described first pet layer 2 and second pet layer 3 scribbles one deck fluorine-containing coat 4 respectively by first pet layer 2 and second pet layer 3 that is composited.
Described basic unit aluminium sheet 1 thickness is 20-30 μ m, and preferred thickness is 25 μ m.
Described first pet layer, 2 thickness are 120-130 μ m, and preferred thickness is 125 μ m.
Described second pet layer, 3 thickness are 70-80 μ m, and preferred thickness is 75 μ m.
Described fluoro-containing coating layer 4 thickness are 20-25 μ m.
The utility model is by scribbling the pet layer of fluorine-containing coat in the two surface recombination settings of basic unit's aluminium sheet, can prevent effectively that aqueous vapor from seeing through enters, strengthen the bearing capacity and the heat-conductive characteristic of product, thereby guarantee the safe in utilization of assembly, scribble fluoro-containing coating, have uvioresistant function at outermost layer, thereby make backboard should be in photovoltaic module the time, generating efficiency is good, prolongs service life, saves Financial cost.
