Abstract:
(EN) The invention relates to PUR rigid foams which can be obtained by reacting an organic polyisocyanate component B) in a specified viscosity range with a hydrogen-containing component A) which is reactive to isocyanate groups, at least containing a polyol component, water, and optionally stabilizers, catalysts, and other auxiliary agents and additives, in the presence of suitable propellants and to a method for producing same, having the steps of a) providing a mold, b) introducing the foam-forming reaction mixture of component A), the polyisocyanate component B), and propellants T) into the mold, and c) foaming the reaction mixture.
(FR) L'invention concerne des mousses de PUR rigides pouvant être obtenues en faisant réagir un composant polyisocyanate organique B) situé dans une plage de viscosité déterminée avec un composant A) contenant de l'hydrogène réagissant avec les groupes isocyanate, contenant au moins un composant polyol, de l'eau et, le cas échéant, des stabilisateurs, des catalyseurs et autres auxiliaires et additifs, en présence d'agents d'expansion appropriés ainsi qu'un procédé pour leur production comprenant les étapes consistant à a) produire un moule et b) introduire dans le moule le mélange réactionnel expansible constitué du composant A), du composant polyisocyanate B) et de l'agent d'expansion T) et c) expanser le mélange réactionnel.
(DE) Gegenstand der Erfindung sind PUR-Hartschaumstoffe erhältlich durch Umsetzung einer organischen Polyisocyanatkomponente B) in einem bestimmten Viskositätsbereich mit einer gegenüber Isocyanatgruppen reaktiven Wasserstoff enthaltenden Komponente A), mindestens enthaltend eine Polyolkomponente, Wasser sowie gegebenenfalls Stabilisatoren, Katalysatoren, und sonstige Hilfs- und Zusatzmittel, in Gegenwart geeigneter Treibmittel sowie ein Verfahren zu deren Herstellung umfassend die Schritte a) Bereitstellen einer Form und b) Einbringen des schaumbildenden Reaktionsgemisches aus Komponente A), Polyisocyanatkomponente B) und Treibmittel T) in die Form und c) Aufschäumen des Reaktionsgemisches.
