Abstract
The utility model discloses a solar battery packaging glue film comprising upper and lower layers of ethylene-nikasol layers and a polyolefins resinol layer between two layers of the ethylene-nikasol layers. The solar battery packaging glue film is used for packaging the back of the battery piece of the solar battery pack, being able to increase the color aesthetics of the assembly, specifically the double-glass assembly and the curtain assembly applied to the photovoltaic buildings; the color layer of the packaging glue film is arranged in middle part; when the assembly is in laminatedly used, the packing elements in the middle layer does not permeate to the upper ethylene-nikasol layer, and does not influence the light-admitting quality of the upper ethylene-nikasol layer; the added various reflecting material can increase the reflection effect of the light and improves the photoelectric conversion efficiency of the assembly; and the polyolefins resinol layer of the packaging glue film can use the cohesive resin with lower cost, thus reducing the cost.
Description
Technical field
The utility model relates to a kind of glued membrane that is used for solar cell package, and especially the encapsulating material of solar module cell back face specifically is meant a kind of packaging adhesive film with three-layer co-extruded composite construction.
Background technology
In the solar module field; Adopt the encapsulating material of ethylene-vinyl acetate packaging adhesive film at present mostly as assembly; Be about to glass, battery sheet and backboard and be packaged together, and the double-edged two-layer ethylene-vinyl acetate glued membrane use of battery sheet all is the material of the same architectural characteristic with two-layer ethylene-vinyl acetate glued membrane.For guaranteeing the high-photoelectric transformation efficiency of assembly, be affixed on the positive ethylene-vinyl acetate glued membrane of battery sheet and must possess the very high transparency, and need not possess the requirement of high transparent for the ethylene-vinyl acetate glued membrane of cell back face.The ethylene-vinyl acetate of high transmission rate must increase production cost, and the bright ethylene-vinyl acetate glued membrane of full impregnated also has limitation in the application facet of assembly.
Provide a kind of among Chinese patent CN 102140314 A and prepared inorganic reflectorized materials such as directly adding titanium white powder in the process at the ethylene-vinyl acetate glued membrane; Through reflecting rate that improves the ethylene-vinyl acetate glued membrane and then the generating efficiency that improves assembly; But there is following defective in the method in practical application: when assembly carries out lamination; Battery sheet up and down two-layer ethylene-vinyl acetate intersects fusion each other; Lower floor's ethylene-vinyl acetate can infiltrate into the upper strata ethylene-vinyl acetate and light transmission is descended, thereby influences the photoelectric conversion efficiency of assembly.
The utility model content
The purpose of the utility model is to provide that a kind of adhesive property is good, ageing-resistant, rich color and the low packaging adhesive film for solar cell of cost.
The technical scheme of the utility model is: a kind of packaging adhesive film for solar cell, described packaging adhesive film for solar cell comprise two-layer ethylene-vinyl acetate layer up and down and are arranged at the polyolefin resin alcohol layer in the middle of the two-layer ethylene-vinyl acetate layer.
In preferred embodiment of the utility model, the thickness range of described ethylene-vinyl acetate layer is 0.1～1mm.
In preferred embodiment of the utility model, described polyolefin type resin layer thickness range is 0.02～0.5mm.
The utility model is said to be a kind of packaging adhesive film for solar cell; This packaging adhesive film for solar cell is used for the encapsulation of solar module cell back face; Can increase the colorful aesthetic property of assembly, especially be applied to the two glass assemblies and the curtain wall component of photovoltaic building; The color layers of packaging adhesive film is in the centre; The filler composition in intermediate layer can not infiltrate into upper strata ethylene-vinyl acetate layer when component lamination was used; Do not influence the light transmission of upper strata ethylene-vinyl acetate layer; And the various reflectorized materials that add can increase the reflection of light effect, the lifting subassembly photoelectric conversion efficiency; But the low adhesion resin of polyolefin type resin layer use cost of packaging adhesive film reduces cost.
Description of drawings
Accompanying drawing 1 is the structural representation of this lining in one preferred embodiment of the utility model packaging adhesive film for solar cell;
Each annex mark is following in the accompanying drawing: 1, ethylene-vinyl acetate layer, 2, polyolefin type resin layer.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection range of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
The utility model is said to be a kind of packaging adhesive film for solar cell, as shown in Figure 1: packaging adhesive film for solar cell comprises two-layer ethylene-vinyl acetate layer 1 up and down and is arranged at the polyolefin resin alcohol layer 2 in the middle of the two-layer ethylene-vinyl acetate layer 1.Ethylene-vinyl acetate layer 1 employing vinyl acetate content is 20～40% ethylene-vinyl acetate resin, wherein adds modified additives such as UV absorbers, oxidation inhibitor, crosslinking agent, and the thickness range of this ethylene-vinyl acetate layer 1 is 0.1～1mm.Polyolefin type resin layer 2 adopts the TPO adhesion resin; Add one or more of pigment, titanium white powder, calcium carbonate, mica powder, wollastonite in powder, quartz sand, nano-oxide, hollow ceramic microballon, the thickness range of this polyolefin type resin layer 2 is 0.02～0.5mm.This packaging adhesive film for solar cell prolongs the method for co-extrusion through adopting three laminar flows; Its ground floor is used ethylene-vinyl acetate resin; The second layer uses polyolefin resin, and the 3rd layer is used ethylene-vinyl acetate resin, can make through twin-screw is three-layer co-extruded.
The utility model is said to be a kind of packaging adhesive film for solar cell; This packaging adhesive film for solar cell is used for the encapsulation of solar module cell back face; Can increase the colorful aesthetic property of assembly, especially be applied to the two glass assemblies and the curtain wall component of photovoltaic building; The color layers of packaging adhesive film is in the centre; The filler composition in intermediate layer can not infiltrate into upper strata ethylene-vinyl acetate layer when component lamination was used; Do not influence the light transmission of upper strata ethylene-vinyl acetate layer; And the various reflectorized materials that add can increase the reflection of light effect, the lifting subassembly photoelectric conversion efficiency; But the low adhesion resin of polyolefin type resin layer use cost of packaging adhesive film reduces cost.
The above is merely the embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed; Variation or the replacement that can expect without creative work all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range that claims were limited.
