Title
(EN) NON-ISOCYANATE POLYURETHANE FOAM COMPOSITION AND METHOD OF MAKING THE SAME
(FR) COMPOSITION DE MOUSSE DE POLYURÉTHANE NON ISOCYANATE ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN)
A thermoset non-isocyanate polyurethane foam (NIPU) composition includes a reaction product of a polycyclic carbonate, a polyamine; and a foaming ingredient including a carbonate-based chemical foaming agent. The reaction product is configured to form a urethane bond. The polycyclic carbonate and the polyamine can be bio-derived. A process for making the NIPU foam includes the steps of: (a) selecting a polycyclic carbonate and a polyamine; (b) mixing the polycyclic carbonate and the polyamine to form a reactant product including a partially cured gel matrix; (c) adding a foaming ingredient comprising a blowing agent including a carbonate; (d) curing the mixture to form the NIPU foam. Optionally, a first catalyst can be added to step (b); and additional foaming ingredients selected from the group consisting of an accelerant, a surfactant, and a combination thereof can be added prior to step (d).

Une composition de mousse de polyuréthane non isocyanate (NIPU) thermodurcie comprend un produit réactionnel d'un carbonate polycyclique et d'une polyamine ; et un ingrédient moussant comprenant un agent moussant chimique à base de carbonate. Le produit réactionnel est conçu pour former une liaison uréthane. Le carbonate polycyclique et la polyamine peuvent être d'origine biologique. La présente invention concerne un procédé de fabrication de la mousse NIPU qui comprend les étapes consistant à : (a) sélectionner un carbonate polycyclique et une polyamine ; (b) mélanger le carbonate polycyclique et la polyamine pour former un produit réactif comprenant une matrice de gel partiellement durcie ; (c) ajouter un ingrédient moussant comprenant un agent d'expansion renfermant un carbonate ; (d) faire durcir le mélange pour former la mousse NIPU. Éventuellement, un premier catalyseur peut être ajouté à l'étape (b) ; et des ingrédients moussants supplémentaires choisis dans le groupe constitué d'un accélérateur, d'un tensioactif et d'une combinaison de ceux-ci peuvent être ajoutés avant l'étape (d).
