FLAME RESISTANT POLYURETHANE MATERIALS CONTAINING MELAMINE-DERIVED ADDITIVES

摘要

Polyurethane foam is disclosed having improved flame retardancy, charring, and intumescent properties. The foam is prepared from a reaction mixture comprising at least one isocyanate or diisocyanate, one blowing agent, one surfactant, one catalyst, and one reactive hydroxyl-terminated oligomeric liquid melamine derivative. The resulting foam provides substantial resistance to burning. A melamine-derived compound having at least alkyl or alkoxy groups, with hydroxy (-OH) termination(s) have proved to be particularly useful in connection with polyurethane foam.
