Description

Verwendung einer Mischung aus anorganischen Füllstoffen mit Bindemitteln zur Herstellung von Schallschluck-,Platten oder -Formteilen I Es ist bekannt, Schallschluckplatten oder -Formteile aus Porenbeton, Asbest, Zement, Faserplatten, Glaswolle, Gesteinswolle oder porigen Kunststoffschaumstoffen herzustellen.Use of a mixture of inorganic fillers with binders for the production of sound-absorbing, plates or molded parts I It is known, sound-absorbing plates or molded parts made of aerated concrete, asbestos, cement, fiberboard, glass wool, rock wool or to produce porous plastic foams.

Es wurde gefunden, daß es möglich ist, Mischungen mit hervorragenden Schallschluckwerten so herzustellen, daß man zu anorganischen Füllstoffen, z. B. Sand, Quarzmehl, Quarzsand mit optimalen Korngrößen, Bindemittel aus Kunststoffen organischer Polymere, wie Phenolformaldehydharz, Polyäthylen, Acetylcellulose, Polystyrol, Polyesterisocyanat zugibt und diese Mischung zur Herstellung von Platten oder Formteilen verwendet, die eine feinporige luftdurchlässige Struktur besitzen. Die so hergestellten Platten zeichnen weh durch hohe Schallschluckwerte aus, es können -sogar Frequenzen oberhalb 5o Hz geschluckt werden.It has been found that it is possible to produce mixtures with excellent To produce sound absorption values in such a way that inorganic fillers such. B. Sand, quartz powder, quartz sand with optimal grain sizes, binders made from plastics organic polymers such as phenol formaldehyde resin, polyethylene, acetyl cellulose, polystyrene, Polyester isocyanate is added and this mixture is used for the production of sheets or molded parts used, which have a fine-pored, air-permeable structure. The so produced Panels are characterized by high sound absorption values, they can even have frequencies be swallowed above 50 Hz.

Die so erzeugten Schallschluckstoffe können als Platten oder Form le in der Weise hergestellt werden, daß im Verhältnizum Füllstoff eine Zugabe von 3 bis 60/, Bindemittel, nach inniger Durchmischung das schüttbare Gut in Rahmen und Profile oder andere Formen eingebracht wird und im Ofen mit einer dem Bindemittel entsprechenden Temperatur gebunden wird. Die so erhaltenen Formteile können oberflächlich durch Schleifen geglättet werden. Es ist auch möglich, den Platten beliAbige Farbtönungen zu geben. Die Festigkeit der so hergestellten Akustikplatten ist für Bauzecke ausreichend. Die Platten können vornehmlich für die Entschallung von Sälen, Bauten, Heizungskanälen usw. Anwendung finden.The sound-absorbing materials produced in this way can be produced as plates or form le in such a way that in proportion to the filler an addition of 3 to 60 /, binder, after thorough mixing, the pourable material is introduced into frames and profiles or other shapes and in the oven with a the binder corresponding temperature is bound. The molded parts obtained in this way can be smoothed on the surface by grinding. It is also possible to give the panels any color shade. The strength of the acoustic panels produced in this way is sufficient for building purposes. The panels can primarily be used for de-sounding halls, buildings, heating ducts, etc.
