Title (EN) CLOSED-CELL FOAM WATERPROOF SHEET WITH ADHESIVE LAYER
(FR) FEUILLE IMPERMÉABLE EN MOUSSE À CELLULES FERMÉES DOTÉE D'UNE COUCHE ADHÉSIVE
(JA) 密着層付き独立気泡発泡体止水シート
Abstract:
(EN) A closed-cell foam waterproof sheet with an adhesive layer, obtained by adhering: an adhesive layer containing a petroleum resin-based tackifier (B) and a rubber component (A) containing a total of at least 80 mass% of a butyl rubber (a1) and an ethylene-propylene-diene rubber (a2), and having a thickness of 0.01-2.0 mm; and a closed-cell foam sheet having a closed-cell ratio of 70% or above, to each other. The closed-cell foam sheet is obtained by foaming a foamable resin composition containing a thermoplastic resin or a rubber-based resin, a weather-resistant agent, and a foaming agent. The weather-resistant agent content is 0.1-8.0 mass parts to 100 mass parts of the thermoplastic resin or the rubber-based resin. The mass ratio of the ethylene-propylene-diene rubber (a2) to the butyl rubber (a1) is 0/100-93/7. The petroleum resin-based tackifier (B) content is 0.5-20 mass parts to 100 mass parts of the rubber component (A). The closed-cell foam waterproof sheet with an adhesive layer has a 25% compressive stress of 10-800 kPa.
(FR) L'invention concerne une feuille imperméable en mousse à cellules fermées dotée d'une couche adhésive, obtenue en faisant adhérer : une couche adhésive contenant un agent poisseux à base de résine de pétrole (B) et un composant caoutchouc (A) contenant un total d'au moins 80 % en masse d'un caoutchouc butylique (a1) et d'un caoutchouc d'éthylène-propylène-diène (a2), et ayant une épaisseur de 0,01 à 2,0 mm; et une feuille en mousse à cellules fermées ayant un rapport de cellules fermées de 70 % ou plus, l'une à l'autre. La feuille en mousse à cellules fermées est obtenue par l'expansion d'une composition de résine expansible contenant une résine thermoplastique ou une résine à base de caoutchouc, un agent résistant aux intempéries et un agent d'expansion. La teneur en agent résistant aux intempéries est de 0,1 à 8,0 partis en masse pour 100 parts en masse de la résine thermoplastique ou de la résine à base de caoutchouc. Le rapport de masse du caoutchouc d'éthylène-propylène-diène (a2) sur le caoutchouc butylique (a1) est de 0/100 à 93/7. La teneur en agent poisseux à base de résine de pétrole (B) est de 0,5-20 parts en masse pour 100 parts en masse du composant de caoutchouc (A). La feuille imperméable en mousse à cellules fermées dotée d'une couche adhésive présente une contrainte de compression à 25 % de 10 à 800 kPa.
(JA) ブチルゴム(a1)及びエチレン-プロピレン-ジエンゴム(a2)の合計含有量が80質量%以上であるゴム成分(A)及び石油樹脂系粘着付与剤(B)を含み、厚さが0.01~2.0mmである密着層と、独立気泡率が70%以上である独立気泡発泡体シートとを密着させてなり、前記独立気泡発泡体シートが、熱可塑性樹脂又はゴム系樹脂と、耐候剤及び発泡剤を含む発泡性樹脂組成物を発泡してなり、前記耐候剤の含有量が、前記熱可塑性樹脂又はゴム系樹脂100質量部に対し0.1~8.0質量部であり、前記ブチルゴム(a1)に対する前記エチレン-プロピレン-ジエンゴム(a2)の質量比が0/100~93/7であり、前記ゴム成分(A)100質量部に対する石油樹脂系粘着付与剤(B)の含有量が0.5~20質量部であり、25%圧縮応力が10~800kPaである、密着層付き独立気泡発泡体止水シート。
