Abstract
The utility model provides a coating back plate which belongs to the technical field of a solar panel back plate and comprises a PET (polyethylene terephthalate) basement layer and hydrolysis endurable treatment layers symmetrically arranged on the two surfaces of the PET basement layer, wherein a PVDF (polyvinylidene fluoride) fluorine film formed by means of compounding is arranged outside the hydrolysis endurable treatment layer on one surface, and a high-fluorine crystal fluorine coating is coated outside the hydrolysis endurable treatment layer on the other surface. PET is short for polyethylene terephthalate and PVDF is short for polyvinylidene fluoride. The hydrolysis endurable treatment layers made of polyester-contained polyamine resin materials are coated on the two surfaces of the PET basement layer, the PVDF fluorine film formed by means of compounding is arranged outside the hydrolysis endurable treatment layer on one surface and the fluorine content is increased, so that the ultraviolent resisting capability is enhanced and the hydrolysis enduring property and adhesion of the whole back plate are greatly improved; when the back plate is applied to a photovoltaic assembly, a PET protective layer has the functions of resisting hydrolysis and oxidation; therefore, the service life is prolonged and the cost is saved.

Technical field
The utility model belongs to solar panel backplane technology field, and being specifically related to a kind of ultra-violet resistance can be strong, the coating backboard of heatproof, excellent in durability.
Background technology
At present, the coating backboard is widely used in the solar cell board industry.Most coating backboard anti-hydrolytic performance is poor, and the uvioresistant ability is low, leads weak point service time, thereby increases economic loss.
The utility model content
At the above-mentioned problems in the prior art, the purpose of this utility model be to provide a kind of ultra-violet resistance can be strong, the coating backboard of heatproof, excellent in durability.
Described a kind of coating backboard, comprise PET basic unit, be symmetricly set on the hydrolysis processing layer on PET basic unit two surfaces, it is characterized in that the wherein outer PVDF fluorine film that is composited that is provided with of hydrolysis processing layer of one side, the hydrolysis processing layer of another side scribbles high fluorine synthetic type fluorine coating outward, described PET is the abbreviation of PETG, and PVDF is the abbreviation of Kynoar.
Described a kind of coating backboard is characterized in that described PET groundwork thickness is 150-300 μ m.
Described a kind of coating backboard is characterized in that described hydrolysis processing layer is anti-hydrolysis, the anti-oxidation protection layer that contains polyester-type polyurethane resin material, and its thickness is 2-3 μ m.
Described a kind of coating backboard is characterized in that described PVDF fluorine film is 59% fluorine film for fluorine content.
Described a kind of coating backboard is characterized in that described high fluorine synthetic type fluorine coating thickness is 15-35 μ m.
Above-mentioned a kind of coating backboard, comprise PET basic unit, be symmetricly set on the hydrolysis processing layer on PET basic unit two surfaces, wherein Yi Mian hydrolysis processing layer is provided with the PVDF fluorine film that is composited outward, the hydrolysis processing layer of another side scribbles high fluorine synthetic type fluorine coating outward, described PET is the abbreviation of PETG, the abbreviation of PVDF Kynoar.The utility model is by scribbling the hydrolysis processing layer that contains polyester-type polyurethane resin material on PET base material two sides; the PVDF fluorine film that is composited is set outside the hydrolysis processing layer of one side; increase fluorine content; thereby improve the uvioresistant ability; whole backboard hydrolytic resistance and adhesive force are improved greatly, make backboard should be in photovoltaic module the time, the PET protective layer has anti-hydrolysis, anti-oxidation function; prolong service life, save financial cost.
