摘要
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.;13 cl, 3 tbl, 6 ex
