Description

本発明は、太陽電池用カプセル封入用粘着フィルム及びその調製方法並びに応用に関する。 The present invention relates to an adhesive film for encapsulating a solar cell capsule, a method for preparing the same, and an application thereof.

白色粘着フィルムは、モジュール下層に使用可能であり、可視光及び近赤外光を反射することにより、モジュールパワーを向上させる目的を達成し、シングルガラスモジュール及びダブルガラスモジュールに応用することができる。モジュールの外観に対する要求は比較的に厳しいが、白色粘着フィルムについて、電池シート、バスバー、はんだテープまでオーバーフローしないとともに、しわ等の欠陥がないことが要求される。 The white adhesive film can be used in the lower layer of the module, achieves the purpose of improving the module power by reflecting visible light and near-infrared light, and can be applied to the single glass module and the double glass module. Although the requirements for the appearance of the module are relatively strict, it is required that the white adhesive film does not overflow to the battery sheet, the bus bar, and the solder tape, and is free from defects such as wrinkles.

従来技術においては、通常、以下のような技術案を採用して白色粘着フィルムの白色のオーバーフロー問題を解決する。 In the prior art, the following technical proposals are usually adopted to solve the white overflow problem of the white adhesive film.

1、予め架橋により粘着フィルム部分を架橋させ、白色のオーバーフローを制御する目
的を達成する予め架橋プロセス。その欠点は、剥離性が劣り、モジュールがベーク熱に弱いという点である。 1. A pre-crosslinking process that achieves the purpose of controlling white overflow by pre-crosslinking the adhesive film portion by cross-linking. Its drawbacks are poor peelability and the module is vulnerable to baking heat.

2、樹脂のメルトフローレートを低下させることにより白色のオーバーフロー発生の可
能性を低下させる低メルトフローレートプロセス。その欠点は、オーバーフローを制御する能力が最適ではなく、モジュールのフランジングが存在することである。 2. A low melt flow rate process that reduces the possibility of white overflow by reducing the melt flow rate of the resin. The disadvantage is that the ability to control overflow is not optimal and there is flanging of the module.

3、1層の不織布を複合することにより、白色の制限を達成する。 Achieve the white limit by combining three or one layer of non-woven fabric.

Added. However, the wavelength of UVA is 320-400 nm, and when the material to be cured is a UV light blocking material, specifically, the pigment / filler (for example, titanium dioxide) in the core layer has a barrier effect on UVA. Therefore, when UVA is used to irradiate the core layer containing the pigment / filler, UVA is blocked, the permeation capacity is limited, the progress of the cross-linking reaction is affected, the cross-linking effect is deteriorated, and at the same time, many uncross-linked small molecules are present. It remains in a free state and affects the performance of the module such as PID resistance and prevention of Snail Trail. In addition, UVA causes great damage to the human body and is prone to carcinogenesis when exposed to UVA for a long period of time, which is disadvantageous for the safe operation of the user.
