The present invention relates to a binder for the production of bonded mineral wool, wherein a phenol-formaldehyde-binder is applied onto the still hot fibers after the fiberization of a mineral wool, using a binder that comprises hydroxylamine or an amino alcohol with the following general formula (I) wherein R1 and R2 are the same or different from each other, and independently are hydrogen, a linear or branched, saturated or unsaturated aliphatic hydrocarbon with 1 -12 carbon atoms, a saturated or unsaturated alicyclic or heterocyclic hydrocarbon with 5-8 carbon atoms, a carbocyclic or heterocyclic aromatic hydrocarbon with 5 - 1 2 ring members or a chain-like or branched alyklether with 1 -50 alkoxy units or a chain-like or branched alkylamine with 1 -50 alkylamine units; and R3 is a linear or branched, saturated or unsaturated aliphatic hydrocarbon with 1-12 carbon atoms, a saturated or unsaturated alicyclic or heterocyclic hydrocarbon with 5-8 carbon atoms, a carbocyclic or heterocyclic aromatic hydrocarbon with 5-12 ring members or a chain-like or branched alkylether with 1 -50 alkoxy units or a chain-like or branched alkylamine with 1-50 alkylamine units. |
