| titleOfInvention | Process for preparing polyurethane soft foams |
| abstract | b1) mindestens einem mindestens zweifunktionellen Polyesterol aufnder Basis von Adipinsäure und mehrfunktionellen Alkoholen mitneiner OH-Zahl von 40 bis 100 mg KOH/g in Anteilen von mehrnals 50 Gew.-%, bezogen auf das Gesamtgewicht der Komponentenb), b2) mindestens einem mindestens zweifunktionellen Polyetherol aufnder Basis von Propylenoxid und/oder Butylenoxid bei einer OH-Zahlnvon größer als 25 mg KOH/g in Anteilen von weniger alsn25 Gew.-%, bezogen auf das Gesamtgewicht der Komponente b), nund gegebenenfalls b3) mindestens einem weiteren Polyetherol auf der Basis vonnEthylenoxid und Propylenoxid und/oder Butylenoxid mit einemnAnteil an primären OH-Gruppen von mehr als 30 % in Anteilennvon 0 bis 25 Gew.-%, bezogen auf das Gesamtgewicht dernKomponente b). The invention relates to a process for the production of flexible polyurethane foams by reacting organic and / or modified organic polyisocyanates (a) with a polyol mixture (b) and optionally further compounds (c) which are reactive toward isocyanates in the presence of water and / or other blowing agents (d), catalysts (e) and optionally further auxiliaries and additives (f), which is characterized in that the polyether mixture (b) consists of b1) at least one at least two-functional polyesterol based on adipic acid and polyfunctional alcohols with an OH number of 40 to 100 mg KOH / g in proportions of more than 50% by weight, based on the total weight of component b), b2) at least one at least two-functional polyetherol based on propylene oxide and / or butylene oxide with an OH number of greater than 25 mg KOH / g in proportions of less than 25% by weight, based on the total weight of component b), and if necessary b3) at least one further polyetherol based on ethylene oxide and propylene oxide and / or butylene oxide with a proportion of primary OH groups of more than 30% in proportions of 0 to 25% by weight, based on the total weight of component b). n n n The invention furthermore relates to those using this methodnmanufactured flexible polyurethane foams themselves as wellntheir use for upholstery purposes, in vehicle construction and innmedical field, in particular for the production of flame-laminatablenor high frequency weldable composites. |
