INSULATING PRODUCT BASED ON MINERAL WOOL SIZED WITH A BINDER BASED ON A PHENOL-FORMALDEHYDE RESIN, SIZING COMPOSITION THEREOF, METHOD OF USING THE SIZING COMPOSITION AND METHOD OF MANUFACTURING THE INSULATING PRODUCT

摘要

The invention Phenol relates to formaldehyde, a binder sizing mineral wool a resin as a raw material in the raw material protection products, the binder is 25% by weight or less with respect to the dry weight of the free formaldehyde content of the resin, the free phenol the content is more than 2.5% by weight based on the dry weight of the resin, diluted in water of F / P is the molar ratio of about 2.5 to 4 phenol (P) and formaldehyde (F) the condensation product neutralized with sulfuric acid in basic medium at a sex and exceeds 500%, obtained by condensing phenol until no more than 1500% - comprises a resole formaldehyde (resol) 60 to 90 parts by weight of the mixture to 10 to 40 parts by weight of the element. The sizing composition is useful for preparing blocked product of reducing the emission of ammonia on the production line.
