PHENOL-FORMALDEHYDE RESIN-CONTAINING GLUING COMPOSITION FOR MINERAL FIBRES AND OBTAINED MATERIALS Russian patent published in 2012 - IPC C08G14/08 C03C25/34 C08J5/24 D06M15/41 

FIELD: chemistry.

SUBSTANCE: gluing composition for mineral fibres contains phenol-formaldehyde resin, urea, a cross-linking catalyst and, if necessary, additives. The catalyst is a mixture of ammonium sulphamate and ammonium sulphate. Heat-insulating and/or sound-insulating material based on mineral fibres is obtained by gluing fibres using said composition.

EFFECT: obtaining a gluing composition for mineral fibres, which is capable of cross-linking at low temperature, making materials based on said composition, which include thin fibres, having improved insulation properties.
