Patent

CA 2489817

A formaldehyde-free aqueous binder composition comprises a binder component (A) obtainable by reacting at least one alkanolamine with at least one carboxylic anhydride and, optionally, treating the reaction product with a base; and a binder component (B) which comprises at least one carbohydrate. The binder composition is particularly useful for bonding mineral fiber products.

La présente invention concerne une composition de liant aqueuse sans formaldéhyde qui comprend : un composant liant (A) que l'on obtient en faisant réagir au moins une alcanolamine avec au moins un anhydride carboxylique et, facultativement, en traitant le produit réactionnel avec une base ; et un composant liant (B) qui comprend au moins un hydrate de carbone. La composition de liant de l'invention est particulièrement utile pour lier des produits de fibres minérales.
