Abstract:
The present invention concerns a method for producing polyurethane foams by reacting an isocyanate component with a component reactive to isocyanates, which comprises at least one polyether carbonate polyol, and wherein the reaction takes place in the presence of urea or derivatives thereof. Furthermore, the invention concerns polyurethane foams produced by the method according to the invention and their application.

Claim (Index 1):
A method for producing polyurethane foams comprising reacting:\n A an isocyanate-reactive component comprising:\n A1 \u226540 to \u2264100 parts by wt. of one or more polyether carbonate polyols having a hydroxyl number according to DIN 53240 of \u226520 mg of KOH/g to \u2264120 mg of KOH/g, \n A2 \u226460 to \u22650 parts by wt. of one or more polyether polyols having a hydroxyl number according to DIN 53240 of \u226520 mg of KOH/g to \u2264250 mg of KOH/g and a content of ethylene oxide of \u22650 to \u226460% w/w, wherein said polyether polyols A2 are free from carbonate units, \n A3 \u226420 to \u22650 parts by wt., relative to the sum of the parts by wt. of components A1 and A2, of one or more polyether polyols having a hydroxyl number according to DIN 53240\u226520 mg of KOH/g to \u2264250 mg of KOH/g, and a content of ethylene oxide of >60% w/w, wherein said polyether polyols A3 are free from carbonate units, \n A4 \u226440 to \u22650 parts by wt., relative to the sum of the parts by wt. of components A1 and A2, of one or more polymer polyols, PHD polyols and/or PIPA polyols, \n and \n A5 \u226440 to \u22650 parts by wt., relative to the sum of the parts by wt. of components A1 and A2, of polyols, which do not fall under the definition of components A1 to A4; \n B a catalyst component comprising:\n B1 \u22650.05 to \u22641.5 parts by wt., relative to the sum of the parts by wt. of components A1 and A2, of urea and/or derivatives of the urea, \n and \n B2 \u22650.03 to \u22641.5 parts by wt., relative to the sum of the parts by wt. of components A1 and A2, of catalysts other than those of component B1, wherein the content of aminic catalysts in component B2 may be no greater than 50% w/w relative to component B1, \n with C di and/or polyisocyanates, D water and/or physical propellants, E excipients and additives as required, wherein said reaction takes place at an isocyanate index of \u226590 to \u2264120, wherein all stated parts by weight of components A1, A2, A3, A4, A5, B1 and B2 are normalised such that the sum of the parts by weight A1+A2 totals 100 in the composition, and wherein neither urea nor its derivatives belong to the \u201caminic catalysts\u201d mentioned in B2.
