The present invention is directed to the manufacture of mineral wool-based insulation and / or sound insulation insulation products, in particular bound by a sizing composition, mainly of resol type thermosetting resins, aimed at limiting the release of formaldehyde. It is about process. The method is characterized in that after the thermosetting resin is crosslinked, applying to the insulating article an agent capable of reacting with formaldehyde, selected from compounds with active methylene (s). Another subject of the present invention is a device for carrying out the above-described process, and an insulation product based on the obtained mineral fibers. |
