| titleOfInvention | Process for the production of sound absorbing and energy absorbing polyurethane foams |
| abstract | The invention relates to a process for producing sound-absorbing and energy-absorbing flexible PUR foams by reacting organic and / or modified organic polyisocyanates (a) with a polyether mixture (b) and, if appropriate, further compounds (c) which are reactive toward isocyanates (c) 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 DOLLAR A b1) at least one two to eight-functional polyetherol on the Basis of propylene oxide and / or butylene oxide and ethylene oxide, the proportion of ethylene oxide, based on the total amount of alkylene oxide used, being more than 40% by weight, with an OH number of 20 to 1000 mg KOH / g and a proportion of primary OH Groups larger than 50%, provided that b1) at least one at least two-functional poly contains etherol b1.1) with an OH number of 20 to 100 mg KOH / g, DOLLAR A b2) at least one two- to six-functional polyetherol based on propylene oxide and / or butylene oxide with an OH number of greater than 30 mg KOH / g and DOLLAR A b3) at least one further polyetherol based on ethylene oxide and propylene oxide with a proportion of primary OH groups of more than 25%, DOLLAR A where component b1) in proportions of more than 30% by weight, based on the total weight of the polyether mixture (b), used ... |
