Die Erfindung betrifft Verfahren zur Herstellung eines flammgeschützten Dämmelementes aus einem Verbundschaumstoff umfassend geschäumtes Polystyrol, in den Partikel oder Stücke eines geschäumten duroplastischen Kunststoffs eingebunden sind. Erfindungsgemäß wird ein schäumbarer oder geschäumter duroplastischer Kunststoff verwendet, der mit einem Flammschutzmittel ausgerüstet ist. Der mit einem Flammschutzmittel ausgerüstete, schäumbare oder geschäumte duroplastische Kunststoff wird geschäumt und/oder in Stücke zerteilt, anschließend mit vorgeschäumten Polystyrol-Partikeln homogen gemischt und die Mischung in einer Form unter Zugabe von Druck und/oder Wärme zu einem Verbundkörper verschweißt. Ferner betrifft die Erfindung ein Dämmelement aus einem Verbundschaumstoff umfassend geschäumtes Polystyrol, in den Partikel oder Stücke eines geschäumten duroplastischen Kunststoffs eingebunden sind. Erfindungsgemäß ist der eingebundene duroplastische Kunststoff mit einem Flammschutzmittel ausgerüstet. Ferner wird die Verwendung eines solchen Dämmelementes zur Schall- und/oder Wärmedämmung einer Gebäudewand oder -decke vorgeschlagen.

摘要:
The present invention provides a method of producing core/shell-type fluorescent dye-containing nanoparticles for immunohistochemical staining or live cell imaging, the method including: the step 1 of polymerizing monomers for thermoplastic resin synthesis in the presence of a fluorescent dye and thereby preparing core particles composed of a thermoplastic resin containing the fluorescent dye; and the step 2 of coating the core particles each with a shell layer composed of a thermosetting resin. By the method of producing fluorescent dye-containing nanoparticles according to the present invention, fluorescent dye-containing nanoparticles having a high brightness, whose dye does not elutes into water, physiological saline, culture medium and the like, can be produced, and the fluorescent dye-containing nanoparticles can be effectively utilized in immunohistochemical staining and live cell imaging.
