DECORATIVE MOLDED FOAMS WITH GOOD FIRE RETARDANT PROPERTIES

This invention relates to a fire-resistant, medium density polyurethane foam. The foam is made up of a) 50 to 90 parts by weight of water blown polyurethane and b) 10 to 50 parts by weight of a solid flame retardant that contains ammonium polyphosphate and zinc borate, and in which the resultant foa...

Zusammenfassung:	This invention relates to a fire-resistant, medium density polyurethane foam. The foam is made up of a) 50 to 90 parts by weight of water blown polyurethane and b) 10 to 50 parts by weight of a solid flame retardant that contains ammonium polyphosphate and zinc borate, and in which the resultant foam contains at least 5% by weight of zinc borate. The present invention also relates to a process for the preparation of these fire-resistant, medium density polyurethane foams. La présente invention concerne une mousse de polyuréthanne moyenne densité ignifuge. La mousse est réalisée à partir a) de 50 à 90 parties en poids de polyuréthanne gonflé à l'eau et b) de 10 à 50 parties en poids d'un ignifuge solide contenant du polyphosphate d'ammonium et du borate de zinc; la mousse ainsi obtenue contenant au moins 5% en poids de borate de zinc. La présente invention concerne également un procédé permettant de préparer ces mousses de polyuréthanne moyenne densité ignifuges.
