| titleOfInvention | Polyurethane foams based on polyethercarbonate polyols |
| abstract | The invention relates to a method for producing polyurethane foams by reacting the following components A a polyol component, containing A1 40 to 100 parts by weight of polyether carbonate polyol with a hydroxyl number according to DIN 53240-1 June 2013 of 20 mg KOH/g to 120 mg KOH/g, A2 0 to 60 parts by weight of polyether polyol with a hydroxyl number according to DIN 53240-1 June 2013 of 20 mg KOH/g to 250 mg KOH/g and an ethylene oxide content of 0 to 60 wt. %, wherein the polyether polyol A2 is free from carbonate units, B B1 a catalyst and B2 optionally auxiliary and additional materials, C water and/or physical blowing agents with D di- and/or polyisocyanates, wherein the production occurs at a characteristic value of 90 to 120 and in the presence of a component K, characterised in that the component K is selected from at least one compound of the following formulas (R 1 )(R 2 )X—C(O)—(Y) m —Z (1) [(R 1 )(R 2 )X—C(O)—N(H)—N(H)—C(O)—R 3 —] 2 (2) [(R 1 )(R 2 )X—R 3 —C(O)—N(H)—] 2 (3), wherein m represents 0 or 1, X represents a hydroxyphenyl group, Y represents —N(H)—, —O—, —O—R 4 — or C 1 - to C 6 -alkyls, Z represents H, a substituted or unsubstituted aryl group or a substituted or unsubstituted heteroaryl group, wherein Z does not represent H when Y represents —O—, R 1 , R 2 respectively represent H, hydroxyl, a substituted or unsubstituted C 1 - to C 6 -alkyl group or —O—R 5 , R 3 represents a substituted or unsubstituted to C 12 -alkylene group, a substituted or unsubstituted C 1 - to C 12 -alkenylene group, R 4 represents a substituted or unsubstituted C 1 - to C 6 -alkylene group, R 5 represents a substituted or unsubstituted C 1 - to C 12 -alkylene group, and the component K is used in a quantity of 0.05 to 10.00 parts by weight, in relation to the sum of the parts by weight of the components A1+A2=100 parts by weight. |
