The invention relates to a method for producing sandwich construction elements for substantially load-bearing and self-supporting building parts. In one embodiment of the invention, a method is provided including a) producing at least one layer of a mechanically bonded fiber nonwoven which is impregnated with a binder based on at least one heat-curable resin system b) curing the heat-curable resin system in order to produce at least one hardened layer of the fiber nonwoven, and fixed thermally, c) bringing a heat-foamable or heat-foamed phenol resin into contact with that surface of at least one hardened layer of the fiber nonwoven which has been modified according to step b), d) possibly annealing the composite produced in a) to c), and e) curing the further binder based on at least one heat-curable resin system.

The invention relates to watery resin dispersions, a process for their manufacture, and a product. To make available resin dispersions that do not pollute the environment during their processing, while simultaneously generating products that have a high glass transition temperature, it is suggested that the watery resin dispersion contain at least components (I), (II) and (III), whereby R: unsubstituted single or polynuclear aromatic rest or with amino groups and/or cyano groups and/or nitrile groups and/or with saturated and/or unsaturated aliphatic Cto Ccarbon chains substituted single or polynuclear aromatic rests R, Rand R: hydrogen, alkyl residue group with up to 15 C atoms or aromatic rest whereby R, Rand Rcan be equal to or different from each other, (II) is a co-dispersion agent based on epoxide resins and/or novolak resins and (II) one surfactant.

The bonding agent composition comprises tannin of pine bark and/or pecan nut, paraformaldehyde and an ammonium salt of a weak acid. It serves inter alia as bonding agent for particle board with high transverse tensile strength, good water resistance and low formaldehyde emission.
