Abstract

Die Erfindung betrifft ein Verfahren zur kontinuierlichen Herstellung von Polyurethan-Sandwichelementen, enthaltend eine obere Deckschicht und eine untere Deckschicht und eine dazwischen liegende, mit den Deckschichten fest verbundene Schicht aus zelligem Polyurethan, bei dem DOLLAR A a) die beiden Deckschichten kontinuierlich in Längsrichtung gefördert werden, so dass zwischen den Deckschichten ein in Längsrichtung der Deckschichten ausgedehnter Spalt entsteht, und DOLLAR A b) die Polyurethan-Reaktionsmischung von oben auf die Oberseite der unteren Deckschicht und von unten auf die Unterseite der oberen Deckschicht anteilig aufgetragen wird, DOLLAR A c) anschließend die Deckschichten mit dem Polyurethan-Reaktionsgemisch in einer Formstrecke geführt werden, in der die Dicke des Polyurethan-Sandwichelements eingestellt wird und in der das Polyurethan-Reaktionsgemisch ausreagiert, und DOLLAR A d) anschließend das ausreagierte Polyurethan-Sandwichelement abgezogen wird, DOLLAR A dadurch gekennzeichnet, dass das Verhältnis des Massenstroms des auf die obere Deckschicht aufgetragenen Polyurethan-Reaktionsgemisches zu dem Massenstrom des auf die untere Deckschicht aufgetragenen Polyurethan-Reaktionsgemisches zwischen 0,001 und 0,2, bevorzugt zwischen 0,002 und 0,1 und besonders bevorzugt zwischen 0,005 und 0,05, liegt.
