Abstract
The utility model discloses a solar energy cell packaging glue film with patterns. The glue film is an EVA glue film, and upper and lower surfaces of the EVA glue film are irregular straight-stripe or oblique-stripe pressure patterns, thickness of the EVA glue film is preferably selected to be 0.3mm-1.0mm, the thickness of the EVA glue film is furtherly and preferably selected to be 0.5mm, and depth of the straight-stripe or oblique-stripe pressure patterns is preferably selected to be 20mum -100mum. According to the solar energy cell packaging glue film with patterns, the EVA film enables each assembly of a solar energy cell to not easily generate bubbles in a laminating process and have relatively good vacuum effects, moreover, peeling among the glue films is easily carried out after rolling of the glue films, a bonding effect among each assembly of the solar energy cell is not influenced.
Description
Technical field
The utility model relates to a kind of solar module, specifically is a kind of scored packaging adhesive film for solar cell.
Background technology
Each assembly stacks gradually laying from top to bottom by the order of glass, packaging adhesive film, cell piece, packaging adhesive film, backboard in the solar cell, then to its heating and vacuumize, packaging adhesive film wherein makes each assembly of stacked laying be bonded to and is integrated as PUR, after melting.
Packaging adhesive film for solar cell mostly is the EVA glued membrane at present, EVA is ethylene-vinyl acetate copolymer, conventional EVA glued membrane be take vinyl acetate (being VA) content at the EVA resin more than 25% as primary raw material, add simultaneously the auxiliary agents such as crosslinking agent, the smooth film shape glued membrane that melt blending obtains by casting apparatus machine-shaping.
This type of EVA glued membrane smooth surface, frictional force is less between glued membrane and the cell piece, and in order in the stacked process of deployment, cell piece easily is shifted with each assembly of solar cell, also be unfavorable for the exhaust of assembly in lamination process, affect vacuumizing effect and end product quality.
And the softening point of EVA glued membrane is about 60 ℃, make the film surface have high adhesion strength, the fusing point of EVA glued membrane descends along with the rising of vinyl acetate content, this high adhesion strength is highly beneficial for the bonding between each assembly of solar cell, but also can cause sticking together easily, being difficult for peeling off between EVA glued membrane rolling caudacoria and the film, bring inconvenience to production; The problem that adopts the method for adding between layers lining paper at the EVA glued membrane to solve prevent adhesion is also arranged, but this not only increases production cost, also so that technique is more loaded down with trivial details, reduce production efficiency.
The utility model content
Technical problem to be solved in the utility model is the defective that overcomes prior art, a kind of scored packaging adhesive film for solar cell is provided, this glued membrane so that be difficult for to produce bubble in each component lamination process of solar cell, vacuumizing effect is better, and peel off easily between this glued membrane rolling caudacoria and the film, can not affect the bond effect between each assembly of solar cell yet.
For solving the problems of the technologies described above, scored packaging adhesive film for solar cell of the present utility model is the EVA glued membrane, and described EVA glued membrane upper and lower surface is the striated embossing of rule, and described striated embossing is vertical bar line or slanted bar line.
As preferably, the thickness of described EVA glued membrane is 0.3mm-1.0mm.
As further preferred, the thickness of described EVA glued membrane is 0.5mm.
As preferably, the degree of depth of described striated embossing is 20 μ m-100 μ m.
In the scored packaging adhesive film for solar cell of the present utility model, described striated embossing is extruded in the EVA of flow casting molding glued membrane upper and lower surface by knurling rolls, and this glued membrane compared with prior art has the following advantages:
1, described striated embossing has improved frictional force, prevent that cell piece is shifted when each assembly lamination order is laid, and when lamination vacuumizes, can form the exhaust passage, the air in the assembly is discharged smoothly, be difficult for producing bubble, improved vacuumizing effect and product quality;
2, EVA glued membrane surface is roughness, thereby so that be detained more air between rolling caudacoria and the film, prevent adhesion, raising peel strength between the glued membrane, nor it is softening rear to the bond effect between each assembly of solar cell to affect the melting of EVA glued membrane.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in figures 1 and 3, scored packaging adhesive film for solar cell of the present utility model is EVA glued membrane 1, and described EVA glued membrane upper and lower surface is the striated embossing 2 of rule, and described striated embossing 2 is the vertical bar line.
In the present embodiment, the thickness of described EVA glued membrane can be preferably 0.3mm-1.0mm.
In the present embodiment, the thickness of described EVA glued membrane is 0.5mm more preferably.
In the present embodiment, the degree of depth of described striated embossing can be preferably 20 μ m-100 μ m.
The striated embossing 2 of present embodiment is extruded in the EVA of flow casting molding glued membrane 1 upper and lower surface by the metal knurling rolls that roller surface is provided with even cannelure or even vertical bar groove.
As shown in Figures 2 and 3, scored packaging adhesive film for solar cell of the present utility model is EVA glued membrane 1, and described EVA glued membrane upper and lower surface is the striated embossing 2 of rule, and described striated embossing 2 is the slanted bar line.
In the present embodiment, the thickness of described EVA glued membrane can be preferably 0.3mm-1.0mm.
In the present embodiment, the thickness of described EVA glued membrane is 0.5mm more preferably.
In the present embodiment, the degree of depth of described striated embossing can be preferably 20 μ m-100 μ m.
The striated embossing 2 of present embodiment is provided with even spiral fluted metal knurling rolls by roller surface and extrudes in the EVA of flow casting molding glued membrane 1 upper and lower surface.
In the scored solar energy packaging adhesive film of above embodiment, described striated embossing 2 has improved frictional force, prevent that cell piece is shifted when each assembly lamination order is laid, and when vacuumizing, lamination can form the exhaust passage, air in the assembly is discharged smoothly, be difficult for producing bubble, improved vacuumizing effect and product quality.
Described EVA glued membrane 1 surface is roughness, thus so that be detained more air between rolling caudacoria and the film, prevent between the glued membrane adhesion, improve peel strength, nor can affect after the glued membrane melting the bond effect between each assembly of solar cell.
