Abstract:
1. A method for producing bonded mineral wool, in which a phenol-formaldehyde-binder is applied onto the still hot fibers after the fiberization of a mineral melt, a binder, which is essentially free of ammonia, and contains hydroxylamine or an amino alcohol with the following general formula: wherein R1 and R2 are the same or different from each other, and independently are hydrogen, a linear or branched, saturated or unsaturated alipathic 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 straight chain or branched alkylether with 1-50 alkoxy units or a straight chain 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 straight chain or branched alkylether with 1-50 alkoxy units or a straight chain or branched alkylamine with 1-50 alkylamine units; and wherein a sugar-containing preparation is added.
