Abstract
The utility model discloses a novel DFPC solar insulating backboard, which is formed by a four-layer structure. The backboard comprises an enhancement layer, and an outer weather-proof layer and an inner weather-proof layer respectively compounded to two sides of the enhancement layer, wherein the enhancement layer is connected with the outer weather-proof layer via a bonding layer, and the outer weather-proof layer is a PVDF (PolyVinylidine DiFluoride) layer which is a single-layer PVDF film. According to the DFPC solar insulating backboard provided by the utility model, the single-layer PVDF film is used in the outer weather-proof layer so that production cost is reduced; adhesive is not required between the enhancement layer and the weather-proof layers under the condition that original equipment is not changed; the inner weather-proof layer employs a direct coating manner; and thus, a compounding process is omitted, the yield is effectively improved, the cost is saved, and the preparation method is simple.

Technical field
The utility model relates to technical field of solar batteries, particularly relates to a kind of novel DFPC solar energy insulating back panel.
Background technology
As is known in the industry, the overall structure of solar-energy photo-voltaic cell roughly but definitely be not limited to and comprise: framework, be installed on solar energy photovoltaic glass on the framework, be positioned at battery sheet (also claiming silicon chip or silicon plate), hot melt adhesive layer, terminal box and the insulating back panel of solar energy photovoltaic glass below.The order of solar cell package is: photovoltaic glass, hot melt adhesive layer, battery sheet, hot melt adhesive layer and insulating back panel.
Solar-energy photo-voltaic cell is positioned at the back side of solar panel with insulating back panel (be called for short solar energy insulating back panel), and the battery sheet is played protection and supporting role, must have reliable insulating properties, water preventing ability and resistance to ag(e)ing.
The solar energy insulating back panel generally has three-decker, and enhancement layer and be compound in outer weathering layer and the interior weathering layer on enhancement layer two sides respectively all is to connect by adhesive usually between enhancement layer and two weathering layers.Present solar energy backboard is important to exist following problem: use adhesive between enhancement layer and the interior weathering layer, but product cost is increased, process loaded down with trivial details.
The utility model content
The technical problem that the utility model mainly solves provides a kind of novel DFPC solar energy insulating back panel, uses adhesive to increase the problem of cost thereby solved between the enhancement layer of solar energy insulating back panel in the prior art and the interior weathering layer.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel DFPC solar energy insulating back panel is provided, combined by four-layer structure, comprise enhancement layer and be compound in outer weathering layer and the interior weathering layer of enhancement layer both sides respectively, be connected by adhesive linkage between described enhancement layer and the outer weathering layer, described outer weathering layer is the PVDF layer, and described PVDF layer is the pvdf membrane of individual layer.
In preferred embodiment of the utility model, described interior weathering layer is the PET protective layer.
In preferred embodiment of the utility model, the thickness of described PET protective layer is 10um.
In preferred embodiment of the utility model, the thickness of described PVDF layer is 25um.
The beneficial effects of the utility model are: novel DFPC solar energy insulating back panel of the present utility model, outer weathering layer uses the pvdf membrane of individual layer, manufacturing cost is lowered, and do not need to use adhesive between enhancement layer and the weathering layer making under the situation that does not change existing equipment, interior weathering layer adopts the directly mode of coating, has reduced once-combined operation, has improved rate of finished products effectively, thereby saved cost, and the preparation method is simple.
Description of drawings
Fig. 1 is the structural representation of the novel DFPC solar energy of the utility model insulating back panel one preferred embodiment;
Fig. 2 is the novel DFPC solar energy of the utility model insulating back panel preparation method's flow chart;
The mark of each parts is as follows in the accompanying drawing: 1, PVDF layer, 2, adhesive linkage, 3, enhancement layer, 4, the PET protective layer.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1, the utility model provides a kind of novel DFPC solar energy insulating back panel, combined by four-layer structure, comprise enhancement layer 3 and be compound in outer weathering layer and the interior weathering layer of enhancement layer 3 both sides respectively, be connected by adhesive linkage 2 between described enhancement layer 3 and the outer weathering layer, described outer weathering layer is PVDF layer 1, and described PVDF layer 1 is the pvdf membrane of individual layer, and manufacturing cost is lowered.
In above-mentioned, described interior weathering layer is PET protective layer 4.PET protective layer 4 in the utility model is to adopt the mode of directly coating to be compound in enhancement layer 3, has reduced the use amount of adhesive, saves cost.
Novel DFPC solar energy insulating back panel in the utility model is superposeed successively by PVDF layer 1, adhesive linkage 2, enhancement layer 3 and PET protective layer 4 and forms.PVDF layer 1 need have good anti-environmental attack ability, and enhancement layer 3 need have the good insulation performance performance, and PET protective layer 4 also need have good adhesive property.Wherein, the thickness of described PVDF layer 1 is 25um; The thickness of described adhesive linkage 2 is 10um; The thickness of described enhancement layer 3 is 250um; The thickness of described PET protective layer 4 is 10um.
As shown in Figure 2; the utility model also provides a kind of preparation method of novel DFPC solar energy insulating back panel; may further comprise the steps: a side that at first described PVDF layer 1 is compound in described enhancement layer 3 by described tack coat 2 hot pressing; the opposite side of enhancement layer 3 carries out surface treatment then, and the treated side that adopts the mode of directly coating to handle well at enhancement layer 3 described PET protective layer 4 forms diaphragm at last.
The novel DFPC solar energy insulating back panel that the utility model discloses, outer weathering layer uses the pvdf membrane of individual layer, manufacturing cost is lowered, and do not need to use adhesive between enhancement layer and the weathering layer making under the situation that does not change existing equipment, interior weathering layer adopts the directly mode of coating, has reduced once-combined operation, has improved rate of finished products effectively, thereby saved cost, and the preparation method is simple.
