Title:
PRODUCTION OF FLAME-RESISTANT SOFT POLYURETHANE FOAM OF REDUCED SMOKE DENSITY AND MELAMINE/EXPANDABLE GRAPHITE/POLYETHER-POLYOL DISPERSION FOR THIS PURPOSE
Document Type and Number:
Japanese Patent JP3164614
Kind Code:
B2
Abstract:
PURPOSE: To produce and provide flame-resistant soft polyurethane foam reduced in the generation of smoke at a time of fire.
CONSTITUTION: A process for producing flame-resistant soft polyurethane foam reduced in the generation of smoke at a time of fire involves reacting (a) an org. polyisocyanate and/or a modified org. polyisocyanate with (b) a high- molecular wt. compd. containing at least two reactive hydrogen atoms and, if desired, (c) a low-molecular wt. chain extender and/or crosslinking agent in the presence of (d) a mixture of flameproofing agents, which contains melamine, expandable graphite and, if desired, at least one further flameproofing agent, pref., a modified or unmodified ammonium polyphosphate, (e) a blowing agent, (f) a catalyst and, if desired, (g) assistants and/or additives, and a melamine/expandable graphite/polyether-polyol dispersion.
