Material zur Wärme- und SchalldämmungMaterial for thermal and sound insulation
Beschreibung:Description:
Die Erfindung betrifft ein Material zur Wärme- und Schalldämmung, insbesondere für Auskleidungen im Motorraum eines Kraftfahrzeuges, für Schalldämpfer-Töpfe in Auspuffanlagen und dergleichen.The invention relates to a material for heat and sound insulation, in particular for linings in the engine compartment of a motor vehicle, for silencer pots in exhaust systems and the like.
In der Praxis besteht das Material zur Wärme- und Schalldämmung für höhere Temperaturen oft aus kurzen, im Schleuderverfahren hergestellten Basaltfasern. Die Basaltfasern sind mit Phenolharz benetzt, das unter einer entsprechenden Polymerisationstemperatur polymerisiert wurde. Durch die Polymerisation erhält das zu einem Formkörper verpresste Material seine Formstabilität. Bei hohen Betriebstemperaturen verflüchtigt sich das Phenolharz, wobei die Zersetzungsprodukte in die Umgebung gelangen. Zurück bleibt eine Matrix aus sehr kurzen, brüchigen Fasern. Die im Schleuderverfahren hergestellten Basaltfasern sind lungengängig und gesundheitlich nicht unbedenklich. Das Material enthält ferner störende Verunreinigungen in Form von Schmelzperlen, die bei der Herstellung von Basaltfasern nach dem Schleuderverfahren unvermeidbar sind.In practice, the material for heat and sound insulation at higher temperatures often consists of short basalt fibers produced using the centrifuge process. The basalt fibers are wetted with phenolic resin that has been polymerized at a corresponding polymerization temperature. The polymerization gives the material, which is pressed into a molded body, its dimensional stability. At high operating temperatures, the phenolic resin evaporates and the decomposition products enter the environment. What remains is a matrix of very short, brittle fibers. The basalt fibers produced using the centrifuge process are respirable and pose a health risk. The material also contains disruptive impurities in the form of melt beads, which are unavoidable when producing basalt fibers using the centrifuge process.
Der Erfindung liegt die Aufgabe zugrunde, ein Material anzugeben, das gute schall- und wärmeisolierende. Eigenschaften aufweist und dessen anorganische Fasern auch bei langer Betriebsdauer nicht ausgeblasen oder abgetragen werden.The invention is based on the object of specifying a material which has good sound and heat insulating properties and whose inorganic fibers are not blown out or worn away even after a long period of operation.
Gegenstand der Erfindung und Lösung dieser Aufgabe ist ein Material zur Wärme- und Schalldämmung, insbesondere für Auskleidungen im Motorraum eines Kraftfahrzeuges, für Schalldämpfer-Töpfe in Auspuffanlagen und dergleichen, bestehend aus einer thermisch verfestigen Mischung aus endlos gezogenen anorganischen Fasern und einem thermoplastischen Hilfsstoff. Als anorganische Fasern eignen sich ™ insbesondere endlos gezogene Basaltfasern, Glasfasern,The subject of the invention and the solution to this problem is a material for heat and sound insulation, in particular for linings in the engine compartment of a motor vehicle, for muffler pots in exhaust systems and the like, consisting of a thermally solidified mixture of endlessly drawn inorganic fibers and a thermoplastic auxiliary material. Suitable inorganic fibers are in particular endlessly drawn basalt fibers, glass fibers,
Al2O3-Fasern, SiO2-Fasern oder Mischungen der genannten, endlos gezogenen Fasern. Die anorganischen Fasern haben dabei eine Länge von einigen Zentimetern. Bewährt haben sich beispielsweise Faserlängen im Bereich zwischen 6 und 10 Zentimetern. Der Durchmesser endlos gezogener Fasern ist in engen Toleranzen einstellbar. Um eine Lungengängigkeit zu vermeiden, werden Fasern verwendet, deren Durchmesser wesentlich größer ist als 3 &mgr;&tgr;&eegr;. Bevorzugt ist ein Faserdurchmesser zwischen 8 und 15 &mgr;&ngr;&agr;. Al 2 O 3 fibers, SiO 2 fibers or mixtures of the above-mentioned endlessly drawn fibers. The inorganic fibers have a length of several centimeters. Fiber lengths in the range between 6 and 10 centimeters have proven to be effective. The diameter of endlessly drawn fibers can be adjusted within narrow tolerances. To avoid lung permeability, fibers with a diameter significantly larger than 3 μm are used. A fiber diameter between 8 and 15 μm is preferred.
Der thermoplastische Hilfsstoff kann pulverförmig oder A 2 0 flüssig in ein aus den anorganischen Fasern bestehendes v- Vlies eingebracht werden. Vorzugsweise werden thermoplastische Fasern als Hilfsstoff verwendet. Die thermoplastischen Fasern sind in homogener Mischung enthalten und dienen der thermischen Verfestigung des Materials. Durch thermische Plastifizierung mit nachfolgender Abkühlung bildet sich eine feste Matrix, die dem Material eine ausreichende Formstabilität verleiht. Als thermoplastische Fasern eignen sich besonders Polyethylen, Polypropylen, Polyamid oder Mischungen aus diesen Fasern. Der Anteil der 0 thermoplastischen Fasern in der Fasermischung beträgt vorzugsweise 10 bis 20 Gew.%.The thermoplastic auxiliary material can be introduced in powder form or in liquid form into a nonwoven fabric made of inorganic fibers. Thermoplastic fibers are preferably used as auxiliary material. The thermoplastic fibers are contained in a homogeneous mixture and serve to thermally solidify the material. Thermal plasticization with subsequent cooling forms a solid matrix that gives the material sufficient dimensional stability. Polyethylene, polypropylene, polyamide or mixtures of these fibers are particularly suitable as thermoplastic fibers. The proportion of thermoplastic fibers in the fiber mixture is preferably 10 to 20% by weight.
Zur Herstellung des erfindungsgemäßen Materials wird aus einer Fasermischung aus anorganischen, endlos gezogenen Fasern unter Verwendung eines thermoplastischen Hilfsstoffes ein Vlies gebildet, das anschließend im wesentlichen ohne Verdichtung durch Erwärmung thermisch zu einer voluminösen Matte verfestigt wird. Ein Zuschnitt der Matte wird anschließend in einer Pressform durch Druck und Wärme zu einem Formkörper umgeformt. Bei dem Formkörper mag es sich um ein Verkleidungsteil für den Motorraum eines Kraftfahrzeuges oder zum Beispiel um einen Schallabsorber für einen Auspufftopf handeln.To produce the material according to the invention, a nonwoven fabric is formed from a fiber mixture of inorganic, continuously drawn fibers using a thermoplastic auxiliary material, which is then thermally solidified to form a voluminous mat by heating, essentially without compression. A cut of the mat is then formed into a molded body using pressure and heat in a press mold. The molded body may be a panel for the engine compartment of a motor vehicle or, for example, a sound absorber for an exhaust muffler.
Der thermoplastische Hilfsstoff kann pulverförmig oder flüssig auf das Vlies aufgegeben werden. Vorzugsweise wird das Vlies jedoch aus einer Mischung aus anorganischen und thermoplastischen Fasern hergestellt.The thermoplastic auxiliary material can be applied to the fleece in powder or liquid form. However, the fleece is preferably made from a mixture of inorganic and thermoplastic fibers.
Das Vlies wird aerodynamisch oder durch Krempeln gebildet 0 und kann eine Dicke bis zu etwa 3 00 mm aufweisen. Bei der anschließenden Formgebung durch Verpressen werden Bereiche partiell mehr oder weniger stark verdichtet, wobei allerdings auch die etwas stärker verdichteten Abschnitte des Formkörpers eine für die Schallabsorption und Wärmeisolation ausreichende Porosität behalten.The fleece is formed aerodynamically or by carding 0 and can have a thickness of up to about 3 00 mm. During the subsequent shaping by pressing, areas are partially compressed to a greater or lesser extent, although even the more strongly compressed sections of the molded body retain a porosity sufficient for sound absorption and heat insulation.
