摘要:
The present invention relates to a process for manufacturing thermal and/or acoustic insulation products based on mineral wool, especially on rock wool or glass wool, bound by a sizing composition based on a thermosetting resin, in particular of resol type, which aims to limit the emissions of formaldehyde.The method is characterized in that it comprises a step that consists in applying a composition of an agent capable of reacting with formaldehyde, chosen from compounds having active methylene(s), to the insulation product, after the thermosetting resin has crosslinked.Another subject of the present invention is the device for carrying out the aforementioned process and the insulating products based on mineral fibers that are obtained.
摘要:
The present invention relates to a sizing composition for mineral fibers, especially glass fibers or rock fibers, containing a liquid phenolic resin having a free formaldehyde content, expressed with respect to the total weight of liquid, of 0.1% or less and a compound capable of reacting with the free formaldehyde.Preferably, the liquid phenolic resin is mainly composed of phenol-formaldehyde and phenol-formaldehyde-amine condensates and has a water dilutability, at 20° C., at least equal to 1000%.Another subject of the present invention is the insulating products based on mineral fibers treated by said sizing composition.
