Procedure for the manufacture of flame retardant polyurethane foam materials with good long-term use properties

摘要

Process for the manufacture of flame retardant polyurethane foam materials from Component A: A1 100 parts by weight of one or more polyether containing charge (A1.1), the charge being a reaction product of a diisocyanate or polyisocyanate with a compound that it has hydrogen reactive atoms against isocyanates, or a mixture of A1.1 a polyether containing charge, the charge being a reaction product of a diisocyanate opoliisocyanate with a compound having hydrogen atoms reactive against isocyanates and, A1.2 other compounds having hydrogen atoms reactive against isocyanates with a pesomolecular of 400-18000, A2 from 0 to 10 parts by weight (with respect to component A1) of compounds having hydrogen atoms reactive against isocyanates with a molecular weight of 62- 399, A3 from 0.5 to 25 parts by weight (with respect to component A1) of water and / or physical foaming agents, A4 from 1 to 9 parts by weight (with respect or to component A1) of red phosphorus, A5 of 0 to 15 parts by weight (with respect to component A1) of adjuvants and additives such as a) catalysts, b) surfactant additives, c) one or more additives selected from the group consisting of reaction retardants, cell regulators, pigments, dyes, flame retardants other than component A4, stabilizers against aging and the effect of atmospheric agents, plasticizers, substances having fungistatic and bacteriostatic activity, fillers and release agents, and Component B: B diisocyanates or polyisocyanates, no ammonium polyphosphate or melamine being used, and the preparation being carried out with an index of 50 to 250.
