Abstract:
(EN) Provided is a sealant sheet which is for a solar cell module and which can sufficiently benefit from an excellent weather resistance improvement effect provided by addition of a "copolymer-type ultra-high molecular weight HALS" while maintaining sufficient transparency. This sealant composition for a solar cell module contains a low-density polyethylene as a base resin, a crosslinking agent, and a hindered amine light-resistant stabilizer, wherein the hindered amine light-resistant stabilizer is a copolymer between a cyclic aminovinyl compound and ethylene, and has a molecular weight of 30,000 or more and a density of 0.930 g/cm3 or more, the content ratio of the cyclic aminovinyl compound to the base resin is 0.1-0.2 mass%, the base resin has a density of 0.900 g/cm3 or less, and the difference in density between the base resin and the hindered amine light-resistant stabilizer is less than 0.050 g/cm3.
(FR) L'invention concerne une feuille d'étanchéité qui est destinée à un module de cellules solaires et qui peut bénéficier suffisamment d'un excellent effet d'amélioration de la résistance aux intempéries, obtenu par l'ajout d'un « HALS de masse moléculaire ultra-élevée de type copolymère » tout en conservant une transparence suffisante. Cette composition d'étanchéité pour module de cellule solaire contient un polyéthylène basse densité en tant que résine de base, un agent de réticulation et un stabilisant résistant à la lumière à amine encombrée (HALS), le stabilisant résistant à la lumière à amine encombrée étant un copolymère entre un composé aminovinyle cyclique et de l'éthylène, et ayant une masse moléculaire de 30 000 ou plus et une masse volumique de 0,930 g/cm3 ou plus, le rapport de teneur du composé d'aminovinyle cyclique à la résine de base étant de 0,1 à 0,2 % en masse, la résine de base ayant une masse volumique de 0,900 g/cm3 ou moins, et la différence de masse volumique entre la résine de base et le stabilisant résistant à la lumière à amine encombrée est inférieure à 0,050 g/cm3 .
(JA) 十分な透明性を保持したまま、「共重合体型超高分子量タイプのHALS」の添加による優れた耐候性向上効果を十分に享受することができる太陽電池モジュール用の封止材シートを提供すること。 低密度ポリエチレンをベース樹脂とし、架橋剤と、ヒンダードアミン系耐光安定剤を、含有する太陽電池モジュール用の封止材組成物であって、前記ヒンダードアミン系耐光安定剤は、環状アミノビニル化合物とエチレンとの共重合体であって、分子量が30000以上、密度が0.930g/cm以上であり、前記ベース樹脂に対する前記環状アミノビニル化合物の含有量比が0.1質量%以上0.2質量%以下であって、前記ベース樹脂の密度は、0.900g/cm以下であって、且つ、前記ベース樹脂の密度と前記ヒンダードアミン系耐光安定剤の密度との差が0.050g/cm未満である、封止材組成物を用いる。
