Abstract

L'invention a pour objet un procédé de fabrication de mousses rigides renfermant des groupes uréthanne et, éventuellement, urée et isocyanurate, caractérisé en ce qu'une mousse rigide de polyuréthanne est obtenue en faisant réagir a) un polyisocyanate aromatique avec b) un composant polyol présentant en moyenne, au moins 3 atomes d'hydrogène réagissant aux isocyanates, et contenant 1) 30 à 80 % en poids d'un polyéther initié par une amine aromatique, de poids moléculaire 300 à 800, à base de 70 à 100 % en poids d'oxyde de 1,2-propylène et de 0 à 30 % en poids d'oxyde d'éthylène, 2) 10 à 40 % en poids d'un polyéther essentiellement initié par du sucrose, de poids moléculaire 400 à 1000, à base de 70 à 100 % en poids d'oxyde de 1,2-propylène et de 0 à 30 % en poids d'oxyde d'éthylène 3) 5 à 30 % en poids d'un polyéther initié par du propylèneglycol, de poids moléculaire 500 à 1500, à base de 70 à 100 % en poids d'oxyde de 1,2-propylène et de 0 à 30 % en poids d'oxyde d'éthylène, 4) du n-pentane et/ou du i-pentane comme agent d'expansion, 5) de l'eau, 6) éventuellement, des matières auxiliaires et des adjuvants, la somme des pourcentages en poids des composants 1), 2) et 3) étant égale à 100.
