摘要:
1. The method of obtaining molded products,! moreover, in the first region, the porous layer is subjected to pressure from ≥ 0 bar to ≤ 150 bar at a temperature from ≥ 0 ° C to ≤ 200 ° C and during the action of pressure in the first region, the porous layer is compressed to a value from ≥ 12.5% to ≤ 100% of its original volume; ! moreover, in the second region, the porous layer is subjected to pressure from ≥ 50 bar to ≤ 150 bar at a temperature from ≤ 100 ° C to ≤ 200 ° C and during pressure in the second region, the porous layer is compressed to a value from ≥ 0% to ≤ 12 5% of its original volume; ! moreover, the porous layer in the first region and in the second region contains polyurethane foam, which is obtained by foaming a composition containing an aqueous dispersion of anionic hydrophilized polyurethane (I), and drying. ! 2. The method according to claim 1, and the molding of the second region is carried out for from ≥ 45 s to ≤ 90 s. ! 3. The method according to claim 1, wherein the composition from which the porous layer polyurethane foam is obtained further comprises additives selected from the group consisting of fatty acid amides, sulfosuccinamides, hydrocarbon sulfonates, hydrocarbon sulfates, fatty acid salts, alkyl polyglycosides and / or block copolymers ethylene oxide / propylene oxide. ! 4. The method according to claim 3, wherein the ethylene oxide / propylene oxide block copolymers have a structure according to the general formula (1):! ! moreover, the coefficient n has values ranging from ≥ 2 to ≤ 200, and the coefficient m has values ranging from ≥ 10 to ≤ 60.! 5. The method according to claim 1, wherein an aqueous dispersion of anionic hydrophilized polyurethane (I) is prepared! A) obtaining isocyanate-functional prepolymers from a reaction mixture containing:! A1) Organic1. Способ получения формованных изделий, ! причем в первой области на пористый слой воздействуют давлением от ≥ 0 бар до ≤ 150 бар при температуре от ≥ 0°С до ≤ 200°С и во
