Abstract
The utility model discloses a high ultraviolet ray blocking type solar packaging backboard comprising a first protection layer disposed on an upper layer, a weather-resistant layer disposed under the first protection layer, a base body disposed under the weather-resistant layer, and a second protection layer disposed under a base layer. The first protection layer is connected with the weather-resistant layer by the bonding agent, the weather-resistant layer is connected with the base body by the boding agent, and the base body is connected with the second protection layer by the bonding agent. By additionally disposing the protection layers on a surface layer and a bottom layer, the service lifetime of the backboard can be greatly improved. In addition, a lower part of the surface layer is provided with the weather-resistant layer, and the double layer waterproof effect can be used to greatly improve the waterproof performance of the backboard, at the same time, the radiation of the ultraviolet ray can be effectively blocked. In addition, the thermosetting adhesive unsaturated polyester resin can be used for the bonding, therefore the packaging performance can be improved.
Description
Technical field
The utility model relates to a kind of solar energy backboard, is specifically related to a kind of high ultraviolet isolating type solar energy packaging back board.
Background technology
Solar module directly is exposed in the atmosphere in use, stand variations in temperature, the erosion of ultraviolet ray irradiation and steam.As not resisting the impact of environment, its opto-electronic conversion performance is easy to decay, lose use value, thereby the research of solar cell package material is very important, receives people's concern.For reaching the enhancing weatherability, intercept ultraviolet ray, the purpose of steam, generally adopt at present two EVA glued membranes that solar cell is wrapped up, and and upper strata glass, back veneer material is hot pressing together, make EVA be melted in cooling, several layer materials are bonded as one, consist of the technique of solar cell, backboard wherein has weathering layer and basic unit's combination usually.This solar cell backboard exists general to the barriering effect of steam, the shortcoming that weathering layer and encapsulating material EVA bonding strength are low.

The purpose of this utility model is to provide a kind of intensity height that blocks water, encapsulation performance is good, ultraviolet isolating is good high ultraviolet isolating type solar energy packaging back board.
The technical solution of the utility model is; a kind of high ultraviolet isolating type solar energy packaging back board; the first protective layer that comprises the upper strata; the weathering layer of the first protective layer below; the second protective layer of the matrix of weathering layer below and basic unit below; described the first protective layer and weathering layer; weathering layer and matrix; be connected by adhesive between matrix and the second protective layer; described the first protective layer is ferroalloy parts; described weathering layer is the UV-531 thin layer; described matrix is polypropylene material; described the second protective layer is the almag layer, and described adhesive is unsaturated polyester resin.
In preferred embodiment of the utility model, the thickness of described the first protective layer and the second protective layer is 5-40um.
In preferred embodiment of the utility model, the thickness of described weathering layer is 20-80um.
In preferred embodiment of the utility model, the thickness of described matrix is 100-160um.
In preferred embodiment of the utility model, the thickness of described adhesive is 10-30um.
Described in the utility model is a kind of high ultraviolet isolating type solar energy packaging back board; by adding respectively protective layer on top layer and bottom; can greatly improve the useful life of backboard; in addition, weathering layer has been installed also below the top layer, double-layer waterproof effect can significantly promote the water resistance of backboard; the simultaneously effectively radiation of shielding of ultraviolet; in addition, undertaken by the resinoid unsaturated polyester resin bonding so that encapsulation performance promotes.
Description of drawings
Fig. 1 is the structural representation in one preferred embodiment of the high ultraviolet isolating type of the utility model solar energy packaging back board;
Each mark is as follows in the accompanying drawing: 1, the first protective layer, 2, weathering layer, 3, matrix, the 4, second protective layer, 5, adhesive.
Embodiment
The below is described in detail preferred embodiment of the present utility model, 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.
Described in the utility model is a kind of high ultraviolet isolating type solar energy packaging back board; referring to shown in Figure 1; the first protective layer 1 that comprises the upper strata; the weathering layer 2 of the first protective layer 1 below; the second protective layer 4 of the matrix 3 of weathering layer 2 belows and basic unit 3 belows; described the first protective layer 1 and weathering layer 2; weathering layer 2 and matrix 3; be connected by adhesive 5 between matrix 3 and the second protective layer 4; described the first protective layer 1 is ferroalloy parts; described weathering layer 2 is the UV-531 thin layer; described matrix 3 is polypropylene material; described the second protective layer 4 is the almag layer, and described adhesive 5 is unsaturated polyester resin.
Further, the thickness of described the first protective layer 1 and the second protective layer 4 is 5-40um.
Further, the thickness of described weathering layer 2 is 20-80um.
