| description | The invention relates to a method for the production of moulded bodies, comprising lignocellulose, made from particles such as fibres or cuttings and organic binders. According to the invention, an improvement in the mechanical properties and a possible reduction in the amount of added binder may be achieved, whereby a surface-active additive, based on a modified polydimethylsiloxane, a polyacrylate or polyacrylate copolymer, is added to the binder before the mixing thereof with the particles.
Die Erfindung betrifft ein Verfahren zur Herstellung lignocellulosehaltiger Formkörper aus Partikeln, wie z. B. Fasern oder Spänen, und organischen Bindemitteln. Zur Verbesserung der mechanischen Eigenschaften sowie zu einer möglichen Verringerung der Bindemittelzugabe wird erfindungsgemäß vorgeschlagen, dass dem Bindemittel vor seiner Vermischung mit den Partikeln ein oberflächenaktives Additiv auf Basis eines modifizierten Polydimethylsiloxan, eines Polyacrylats oder Polyacrylat-Copolymers zugegeben wird. |
