CA 2586608

An aqueous binder composition for mineral fibers comprises: - a water-soluble binder component obtainable by reacting at least one alkanolamine with at least one carboxylic anhydride and, optionally, treating the reaction product with a base; and - at least one hydrolytic stability-improving agent selected from monoalkanolamines; allylamines; peroxy compounds; epoxy compounds; compounds having at least one long-chain aliphatic moiety and at least one functional group; and SBR latices.

L'invention concerne une composition de liant aqueux destinée à des fibres minérales et comprenant: un composant de liant hydrosoluble pouvant être obtenu par mise à réagir au moins d'une alkanolamine avec au moins un anhydride carboxylique et, éventuellement, par traitement du produit de réaction avec une base; et au moins un agent améliorant la stabilité hydrolytique sélectionné parmi des monoalkanolamines; des allylamines; des composés péroxy; des composés époxy; des composés comprenant au moins une fraction aliphatique à chaîne longue et au moins un groupe fonctionnel; et des micelles SBR.
