Stable polyol compositions and use thereof in preparation of polyurethane foam |
| abstract |
PRODUCTION OF POLYURETHANE FOAMS BY REACTION OF A POLYISOCYANATE WITH A MIXTURE OF A POLYETHER POLYOL AND STERICALLY HINDERED AROMATIC POLYAMINE IN THE PRESENCE OF A BLOWING AGENT CONSISTING SOLELY OF A HALOGENATED HYDROCARBON, A TERTIARY AMINE CATALYST AND A DIVALENT LEAD CATALYST. THE POLYURETHANE FOAMS ARE PREFERABLY PRODUCED BY A ONE-SHOT METHOD INVOLVING REACTION OF A TWO PACKAGE SYSTEM COMPRISING (1) A POLYISOCYANATE WITH (2) A STORAGE STABLE COMPOSITION OF MATTER COMPRISING (A) A POLYETHER POLYOL; (B) A STERICALLY HINDERED AROMATIC POLYAMINE; (C) A HALOGENATED HYDROCARBON BLOWING AGENT; (D) A TERTIARY AMINE CATALYST; AND (E) A DIVALENT LEAD CATALYST, SAID POLYOL AND SAID DIAMINE BEING PRESENT IN SUCH PROPORTION TO PROVIDE AN AMINE/HYDROXYL GROUP RATIO OF BETWEEN ABOUT 1 AND 4. |
