Title
(EN) LAMINATED SHEET AND SOLAR CELL BACKSHEET USING SAME
(FR) FEUILLE STRATIFIÉE ET FEUILLE DE DOS DE CELLULE SOLAIRE L'UTILISANT
(JA) 積層シートおよびこれを用いてなる太陽電池バックシート
Abstract
(EN)
Disclosed are a laminated sheet and a solar cell backsheet using the same, the laminated sheet comprising a two-layer sheet 30 formed by bringing an L1 layer 10 and an L2 layer 20 into contact with each other, the L1 layer 10 comprising 50-99 parts by mass of an ethylene-based polymer (E1) having a density of 0.890-970 kg/m3 and 1-50 parts by mass of a propylene-based polymer (P1), and the L2 layer 20 comprising 50-100 parts by mass of a propylene-based polymer (P2) and 0-50 parts by mass of an ethylene-based elastomer (E2) having a density of 850 kg/m3 or more and less than 890 kg/m3. The laminated sheet is characterized in that the propylene-based polymer (P1) comprises a propylene-based elastomer (P1a) which contains a propylene-derived structural unit and an ethylene-derived structural unit and/or an α-olefin-derived structural unit with 4 to 20 carbon atoms, and which has a melting point (Tm) that is lower than 120°C or not observable.

L'invention concerne une feuille stratifiée et une feuille de dos de cellule solaire l'utilisant, la feuille stratifiée comportant un feuille 30 à deux couches formée en amenant une couche L1 10 et une couche L2 20 en contact mutuel, la couche L1 10 comportant 50 à 99 parties en masse d'un polymère (E1) à base d'éthylène présentant une masse volumique de 0,890 à 970 kg/m3 et 1 à 50 parties en masse d'un polymère (P1) à base de propylène, et la couche L2 20 comportant 50 à 100 parties en masse d'un polymère (P2) à base de propylène et 0 à 50 parties en masse d'un élastomère (E2) à base d'éthylène présentant une masse volumique au moins égale à 850 kg/m3 et inférieure à 890 kg/m3. La feuille stratifiée est caractérisée en ce que le polymère (P1) à base de propylène comporte un élastomère (P1a) à base de propylène qui contient une unité structurale dérivée du propylène et une unité structurale dérivée de l'éthylène et/ou une unité structurale dérivée d'une α-oléfine comportant 4 à 20 atomes de carbone, et qui présente un point de fusion (Tm) inférieur à 120°C ou non observable.
