Abstract[English]
A two-component spray flexible polyurethane foam system includes an isocyanate component including a polymeric isocyanate present in an amount between about 40 percent and about 50 percent by weight and a resin component reactive with and separate from the isocyanate component. The resin component includes a polyether polyol having a weight average molecular weight of between about 4000 and about 7000 grams per mole present in an amount between about 40 and about 55 percent by weight. The resin component also includes a blowing agent and an alkyl triol present in an amount between about 0.1 and about 0.5 percent by weight to delay foaming by at least one second. The resin component further includes a diorganotin dilauryl mercaptide present in an amount between about 0.005 and about 0.05 percent by weight to catalyze foaming within at most five seconds.[French]
Selon l'invention, un système de mousse de polyuréthane souple à pulvérisation à deux composants comprend un composant isocyanate comprenant un isocyanate polymère présent en une quantité comprise entre environ 40 pour cent et environ 50 pour cent en poids et un composant de résine capable de réagir avec le composant isocyanate et séparé de celui-ci. Le composant de résine comprend un polyéther polyol ayant une masse moléculaire moyenne en poids comprise entre environ 4000 et environ 7000 grammes par mole présent en une quantité comprise entre environ 40 et environ 55 pour cent en poids. Le composant de résine comprend également un agent gonflant et un alkyl triol présent en une quantité comprise entre environ 0,1 et environ 0,5 pour cent en poids pour retarder le moussage d'au moins une seconde. Le composant de résine comprend en outre un dilauryl mercaptide de diorganoétain présent en une quantité comprise entre environ 0,005 et environ 0,05 pour cent en poids pour catalyser le moussage en au plus cinq secondes.
