Description
Technical field
The utility model is related to a kind of complex type solar backboard.
Background technology
Backboard is the encapsulation and insulating materials applied to photovoltaic module, and important branch is provided for the component service life of 25 years
Hold.It is arranged at the back side of component, therefore is called " backboard " or " notacoria ".The outside of backboard and air contact, it is long in use
Phase is subjected to oxygen and water vapour in ultraviolet, dust storm, air, damp and hot and wet freeze etc. corrodes and impacted.Pass through on the inside of backboard
The EVA layer of crosslinking curing is bonded with cell piece, alleviates external shock power, plays a part of protecting component generator unit.Due to silicon
The temperature effect of solar cell, the peak power of photovoltaic module is reduced with the rise of module operating temperature.Meanwhile, component table
The rise of face temperature has the effect of aggravation aging to the encapsulating material of component internal, influences the service life of component.In order to drop
The operating temperature of low component is, it is necessary to improve the light reflectivity of backboard.
The Chinese utility model patent of Application No. 201620484627.3 discloses a kind of high reflection type solar energy backboard,
The backboard is 5 layers " sandwich " formula structure.Although the reflectivity of backboard can be improved, layers cementing is used due to two-sided
Mode weathering layer is set, complex process, cost of manufacture is higher.
Utility model content
Problem to be solved in the utility model is to provide that a kind of manufacturing cost is low, is integrated with ply adhesion type backboard and coating
The complex type solar backboard of the advantage of type backboard.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：Complex type solar backboard, the back of the body
Plate includes fluorine film weathering layer, adhesive linkage, substrate layer and high reflection weathering layer, the fluorine film weathering layer and air contact, institute successively
High reflection weathering layer is stated for fluorine resin coat film, the thickness of the thickness of the fluorine film weathering layer and the high reflection weathering layer is big
Cause suitable.
The fluorine film weathering layer is polyvinyl fluoride thin film or polyvinylidene difluoride film.
The thickness of the fluorine film weathering layer is 5~40 μm.
The thickness of the adhesive linkage is 5~15 μm.
The thickness of the substrate layer is 0.05~0.35mm.
The fluorine resin is following one or more kinds of mixing：Polyvinyl fluoride, Kynoar, polytetrafluoroethyl-ne
Alkene, perfluoroethylene-propylene, fluorubber, CTFE-alkyl vinyl ether co-polymer.
The thickness of the high reflection weathering layer is 5~30 μm.
The utility model provides a kind of 4 Rotating fields backboard, and the side of air surface is provided with adhesive linkage in substrate layer
With fluorine film weathering layer, the side of EVA faces (photovoltaic cell packaging adhesive film) is being provided with high reflection weathering layer.Cost of manufacture
Low, backboard, up to more than 85%, and possesses good resistance to UV aging in reflectivity interval 400nm-1100nm.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model complex type solar backboard
Embodiment
Complex type solar backboard as shown in Figure 1, the backboard includes fluorine film weathering layer 1, adhesive linkage 2, substrate layer 3 successively
With high reflection weathering layer 4, the fluorine film weathering layer and air contact, the high reflection weathering layer is the coat film of fluorine resin,
Transparent weathering layer is covered on transparent substrate layer using methods such as dipping, spraying, roller coat or showerings, the fluorine film is weather-proof
The thickness of the thickness and the high reflection weathering layer of layer is roughly the same.
Fluorine film weathering layer 1 is polyvinyl fluoride (PVF) or Kynoar (PVDF) film, and thickness is 5~40 μm.
Adhesive linkage 2 is gluing oxidant layer, and thickness is 5~15 μm.
Substrate layer 3 be polyethylene terephthalate (PET) film, polybutylene terephthalate (PBT) (PBT) film,
Any one in PTT (PTT) film, PEN (PEN) film, thickness is
0.05~0.35mm.
High reflection weathering layer 4 is the coat film of fluorine resin, and thickness is 5~30 μm, and fluorine resin is following one kind or two
Plant the mixing of the above：Polyvinyl fluoride, Kynoar, polytetrafluoroethylene (PTFE), perfluoroethylene-propylene, fluorubber, CTFE-alkane
Base vinyl ether co-polymer.
The utility model backboard is integrated with the advantage of ply adhesion type backboard and application type backboard, and air surface is viscous using interlayer
The mode connect sets weathering layer so that backboard has good adhesion strength, and processing characteristics is good；EVA faces use and are applied as
The mode of film sets weathering layer, and process is simplified on the basis of performance is ensured；The application of high reflection weathering layer, is improved
The light reflective properties and resistance to UV aging of backboard, can effectively reduce the operating temperature of component, extend the service life of component.
