Abstract

L'invention concerne une composition pour former un polyuréthane ignifuge, de la peau et un aérostat. La composition comprend du polyuréthane, de l'hypophosphite d'aluminium, du phosphate de diphényl crésyle et du trioxyde d'antimoine. Dans la préparation d'un matériau de polyuréthane ignifuge à l'aide du matériau de polyuréthane, de l'hypophosphite d'aluminium, du phosphate de diphényl crésyle et du trioxyde d'antimoine en tant que matières premières, les trois agents ignifuges de celui-ci peuvent être dispersés dans le polyuréthane dans une structure spéciale, qui, en combinaison avec l'effet synergique des composants, permet au matériau de polyuréthane modifié préparé à l'aide des matériaux de départ ci-dessus d'avoir d'excellentes propriétés ignifuges et anti-vieillissement.
