Abstract
Die Erfindung betrifft einen treibmittelfreien Aminoharzschaum, der aus einem Aminoharz und hydrophoben Nanopartikeln aufgebaut ist. Ebenso betrifft die Erfindung ein Verfahren zur Herstellung derartiger Aminoharzschaeume durch Aufschaeumen einer Dispersion eines Aminoharzvorkondensats, den Nanopartikeln und Luft mit anschliessendem Aushaerten. Verwendung finden die erfindungsgemaessen Aminoharzschaeume aufgrund ihrer Material- und Grenzflaecheneigenschaften als Schall- und Energiedaemmstoffe.
EP 1808454 A2 UPAB: 20071002 NOVELTY - Propellant free amino resin foam (I) comprises amino resin and at least a hydrophobic nanoparticle of an inorganic and/or organic material at the surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a prepartion of propellant-free amino resin foam comprising dispersing a mixture of an aqueous solution containing at least an amino resin foam-prepolymer and at least a surface hydrophobic nanoparticle of an inorganic and/or organic material; condensating the amino resin prepolymer by simultaneous intensive interfering of air to produce a ternary dispersion of amino resin/nanoparticles/air; and thermally inducing the dispersion to the amino resin foam. USE - (I) is useful to prepare insulating materials for sound- or thermal insulation (claimed). (I) is also useful in other energy insulation. ADVANTAGE - (I) provides better safety. (I) exhibits non-flammability characteristics even there is no any additional flame protection additive or equipment. (I) is highly flexible, soft and mechanically stable. (I) exhibits improved material and surface characteristics such as water rejecting effect. (I) exhibits thermal stability upto 160degreesC.
