Abstract

L'invention concerne des mousses rigides de polyuréthanne à suppression de fumée. Ces mousses sont préparées à partir d'un mélange réactionnel comprenant, en tant qu'additif inhibiteur de la formation de fumée, un sel métallique d'un dialkyldithiocarbamate, d'un mercaptobenzothiazole, d'un 2,5-dimercapto-1,3,4-thiadazole, d'une mercaptotriazone, d'un hydroxythiophénol ou d'un composé dimercapto aliphatique contenant 2 à 10 atomes de carbone. Ces additifs permettent de diminuer la quantité de fumée dans une proportion pouvant atteindre 50 %, lors de la combustion de la mousse de polyuréthanne.
