    摘要： The invention relates to a method for the manufacture of mineral wool, comprising reacting an aqueous phenolformaldehyde resole with free formaldehyde with a first amount of urea, thereby preparing a prereact; contacting the prereact with a second amount of urea; applying the resulting mixture of prereact and second amount of urea, as part of a binder, optionally with additives, to the surface of mineral fibers; and curing the binder on the surface of the mineral fibers. The total amount of urea used ranges 10-40 wt.% relative to the sum of the dry weight of the phenolformaldehyde resole and the total amount of urea, and the second amount of urea used is at least 40 wt.-% of the total amount of urea. The invention also relates to a mineral wool product with reduced emissions of formaldehyde obtained by the method.

    摘要： The invention relates to a method for the manufacture of mineral wool, comprising reacting an aqueous phenol-formaldehyde resole with free formaldehyde with a first amount of urea, thereby preparing a prereact; contacting the prereact with a second amount of urea; applying the resulting mixture of prereact and second amount of urea, as part of a binder, optionally with additives, to the surface of mineral fibers; and curing the binder on the surface of the mineral fibers. The total amount of urea used ranges 10-60 wt.% relative to the sum of the dry weight of the phenol-formaldehyde resole and the total amount of urea, provided that when Ut is between 10-40 wt. %, the second amount of urea (U2) used in c) is between 10-39 wt.% of the total amount of urea (Ut), and when Ut is between 41-60 wt.%, the second amount of urea (U2) used in c) is at least 10 wt.% of the total amount of urea (Ut). The invention also relates to a mineral wool product with reduced emissions of formaldehyde obtained by the method of the invention.
