METODO PARA PRODUCIR PRODUCTOS AISLANTES A BASE DE FIBRAS MINERALES O FIBRAS ORGANICAS DE ORIGEN NATURAL.
The present invention relates to a method for producing an insulation product comprising mineral fibres or organic fibres of natural origin bound by an organic binder, the method comprising the following steps: (a) applying a bonding composition to the mineral fibres or organic fibres of natural origin; (b) forming an assembly of said mineral fibres or organic fibres of natural origin; (c) heating the assembly of the mineral fibres or organic fibres of natural origin until the bonding composition has cured, characterised in that the bonding composition comprises: at least one lignin, which is potentially oxidised, and at least one non-polymeric polycarboxylic organic acid. The invention also relates to the insulating products that can be obtained by means of such a method.
