Title: (DE) VERFAHREN ZUR HERSTELLUNG EINES DÄMMSTOFFES
(EN) METHOD FOR PRODUCING AN INSULATING MATERIAL
(FR) PROCÉDÉ POUR PRODUIRE UN MATÉRIAU ISOLANT
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung eines Dämmstoffes, bei dem ein natürliche Hohlräume, insbesondere natürliche Poren umfassendes pflanzliches Ausgangsmaterial mit einem Hydrophobierungsmittel behandelt wird, hiernach das behandelte Ausgangsmaterial trocknet und das getrocknete hydrophobierte Ausgangsmaterial mit einem wässrigen Bindemittel gebunden wird wobei das Bindemittel vor der Vermischung mit dem hydrophobierten, getrockneten Ausgangsmaterial oder aber die aus Bindemittel und hydrophobiertem Ausgangsmaterial vermischte Gesamtmasse durch Unterhebung eines gasförmigen Fluids zu einem Schaum gerührt/geschlagen wird und/oder zur Bildung eines Schaumes dem Bindemittel vor der Vermischung mit dem hydrophobierten, getrockneten Ausgangsmaterial oder aber der vermischten Gesamtmasse ein Porenbildner zugefügt wird, insbesondere ein Gasblasen bildender Zusatz zugefügt wird.
(EN) The invention relates to a method for producing an insulating material, in which a plant-based starting material comprising natural cavities, especially natural pores, is treated with a hydrophobizing agent, then the treated starting material is dried and the dried hydrophobized starting material is bound with an aqueous binder, wherein the binder prior to the mixing with the hydrophobized dried starting material or else the mixed overall composition composed of binder and hydrophobized starting material is stirred/beaten to a foam by folding in a gaseous fluid and/or a foam is formed by adding a pore former, especially an additive that forms gas bubbles, to the binder prior to the mixing with the hydrophobized dried starting material or else to the mixed overall composition.
(FR) L'invention concerne un procédé servant à produire un matériau isolant. Selon ledit procédé, un matériau de départ végétal comprenant des cavités naturelles, en particulier des pores naturels, est traité à l'aide d'un agent d'hydrophobisation. Le matériau de départ traité est par la suite séché, et le matériau de départ séché rendu hydrophobe est lié à un liant aqueux. Le liant, avant d'être mélangé au matériau de départ rendu hydrophobe, séché, ou la masse totale mélangée composée du liant et du matériau de départ rendu hydrophobe est agité(e)/battu(e) en une mousse sous l'action d'un fluide sous forme gazeuse, et/ou un agent porogène, en particulier un additif formant des bulles de gaz, est ajouté au liant avant le mélange au matériau de départ rendu hydrophobe séché ou à la masse totale mélangée afin de former une mousse.
