| titleOfInvention | Washable visco-elastic soft polyurethane foams |
| abstract | The present invention relates to a process for the preparation of viscoelastic flexible polyurethane foams having an air permeability of at least 1 dm 3 / s, comprising (a) polyisocyanate with (b) polymeric compounds with isocyanate-reactive groups, (c) optionally Kettenverlängerungs- and / or Crosslinking agent, (d) optionally compounds with only one isocyanate-reactive group having a hydroxyl number of 100 to 500 mgKOH / g, (e) catalyst, (f) propellant and optionally (g) additives mixed into a reaction mixture and converted to the flexible polyurethane foam, wherein the polymeric compounds having isocyanate-reactive groups (b) 10 to 40 wt .-% of at least one polyalkylene oxide (b1) having a hydroxyl number of 90 to 300 mgKOH / g, starting from a 3 to 6-functional starter molecule and a Propylenoxydanteil, based on the content of alkylene oxide, from 80 to 100 wt .-%, 5 to 20 wt .-% at least e ines Polyalkylenoxids (b2) having a hydroxyl number of 10 to 60 mgKOH / g, starting from a 2 to 4-functional starter molecule and a propylene oxide, based on the content of alkylene oxide, from 80 to 100 wt .-%, 10 to 50 wt. -% of at least one polyalkylene oxide (b3) having a hydroxyl number of 10 to 55 mgKOH / g, starting from a 2 to 4-functional starter molecule and an ethylene oxide content, based on the content of alkylene oxide, of 70 to 100 wt .-% and 0 to 20 wt .-% of at least one polyalkylene oxide (b4) having a hydroxyl number of 50 to 200 mgKOH / g, starting from a 2-functional initiator molecule and an ethylene oxide, based on the content of alkylene oxide, from 80 to 100 wt .-%, included and wherein the proportion of the compounds b1) to b4), based on the total weight of the polymeric compounds with isocyanate-reactive groups (b), at least 80 wt .-% is. Further, the present invention relates to a viscoelastic polyurethane foam having an air permeability of at least 1 dm 3 / s, which is obtainable by such a method, and the use of such a polyurethane foam for mattresses and pillows. |
