[0105] experiment method

[0106] 1. Peel strength test between the base layer and the bonding layer in the laminated film

[0107] The laminated film was cut into 2.54cm wide and 10cm long strips, and the bonding layer and the base layer were respectively fixed in the upper and lower fixtures of the tensile testing machine, and the peeling test was performed at a speed of 5 inches / min.

[0108] 2. Peel strength test between the bonding layer of the laminated film and the ethylene-vinyl acetate copolymer packaging material Laminate the laminated film (the bonding layer is close to the packaging film), the vinyl acetate copolymer packaging film, and the glass in order, Put it in a laminator for vacuum lamination and cross-linking, and the operating conditions are set at 140° C. for 15 minutes. Then the sample was cut into 2.54cm wide and 10cm long strips, and the laminated film of the backplane and the packaging material / glass layer were respectively fixed in the upper and l...

Abstract

The invention discloses a laminated film which comprises (a) a base layer and (b) a bonding layer on a main surface of the base layer, wherein the bonding layer is selected from (i) ethylene-(methyl) acrylic acid C1-4 alkyl ester copolymer, and ethylene-(methyl) acrylic acid copolymer or ethylene-maleic anhydride copolymer; (ii) multi-copolymer formed by ethylene and at least two comonomers selected from (methyl) acrylic acid C1-4 alkyl ester copolymer and the ethylene-(methyl) acrylic acid copolymer or the ethylene-maleic anhydride copolymer; (iii) copolymer containing glycidyl methacrylate formed by the ethylene, the glycidyl methacrylate and at least one comonomer selected from the (methyl) acrylic acid C1-4 alkyl ester copolymer, the ethylene-(methyl) acrylic acid copolymer or the ethylene-maleic anhydride copolymer; or (iv) blend of two or more of the copolymers, wherein the bonding layer is directly placed on the base plate or a base coating with the thickness of less than 0.99 mu m is arranged between the base layer and the bonding layer.

Description

technical field [0001] The present invention relates to a polymer laminated film having improved bonding strength between layers, which not only has improved bonding strength between its layers, but also is compatible with ethylene-acetic acid as a solar cell module encapsulation material. Vinyl ester copolymers have improved joint strength. The invention also relates to a solar cell panel made with the polymer laminate film. Background technique [0002] With the warming of the global climate, the governments of various countries have higher and higher requirements for energy conservation and emission reduction. Therefore, finding new energy sources to replace fossil fuels has become an urgent problem to be solved. [0003] Solar energy is a clean, pollution-free and inexhaustible source of energy. At present, solar energy is mainly converted into electrical energy through solar panels, which is then used to drive electric water heaters, electric vehicles, satellite comp...
