Isocyanurate groups containing polyisocyanate mixtures, process for their preparation and their use in the preparation of polyurethane foams |
| abstract |
Liquid polyisocyanate mixtures containing isocyanurate groups with an NCO content of 15 to 30% by weight, obtainable by trimerization of part of the isocyanate groups of polyisocyanate mixtures of the diphenylmethane series with a content of diisocyanatodiphenylmethane isomers of 80 to 100% by weight and 0 to 20% by weight .-% of higher than difunctional polyisocyanates of the diphenylmethane series, the diisocyanatodiphenylmethane isomers being 40 to 80% by weight of 4,4'-diisocyanatodiphenylmethane, 20 to 60% by weight of 2,4'-diisocyanatodiphenylmethane and 0 to Compose 8% by weight of 2,2'-diisocyanatodiphenylmethane and add the percentages mentioned to 100 by carrying out the trimerization to the desired degree of trimerization in the presence of a catalyst which accelerates the trimerization, if appropriate with the use of hydroxyl group-containing components it then breaks off by adding a catalyst poison. The liquid polyisocyanate mixtures thus obtained are used for the production of polyurethane foams. |
