Abstract

L'invention a pour objet un procédé de préparation de dispersions aqueuses de polyuréthane, exemptes d'émulsifiants, suivant des méthodes connues en soi, à partir de : a. composés dihydroxylés d'un poids moléculaire de 500 à 5 000; b. diisocyanates ; c. sels, solubles dans l'eau, d'acides aminocarboxyliques ou aminosulfoniques aliphatiques, ayant au moins un atome d'hydrogène fixe sur de l'azote; et d. composés exempts de groupes salins, ayant 2 atomes d'hydrogène pouvant réagir avec des groupes isocyanate, et d'un poids molaire inférieur à 300. Dans le procédé de l'invention on utilise comme diisocyanate une combinaison de diisocyanates aromatiques et aliphatiques ou cycloaliphatiques, ayant une proportion de 10 à 50 % en moles de diisocyanates (cyclo)aliphatiques, et on introduit, soit d'abord les diisocyanates aromatiques, puis les diisocyanates (cyclo)aliphatiques, soit les deux en même temps.
