Beschreibung
Zusammenfassung:	The invention is directed to an aqueous binder composition made of a mixture of i) a phenol-urea-formaldehyde binder (PUF binder), and ii) a protein binder comprising at least one protein and iii) at least one cross-linker selected from phenol containing compounds. The aqueous binder composition is suitable for producing a mineral fibre product by contacting mineral fibres with the aqueous binder composition and curing the binder. L'invention concerne une composition de liant aqueuse constituée d'un mélange de i) un liant phénol-urée-formaldéhyde (liant PUF), et ii) un liant protéique comprenant au moins une protéine et iii) au moins un agent de réticulation choisi parmi les composés contenant du phénol. La composition de liant aqueuse est appropriée pour produire un produit à base de fibres minérales par mise en contact de fibres minérales avec la composition de liant aqueuse et durcissement du liant.
