Abstract
Description
"Verfahren zum Herstellen von Material mit hohen"Method of producing material with high
Schall- und Wärmedämmeigenschaften aus Altpapier und/oder Pappe" Die Erfindung betrifft ein Verfahren zum Herstellen von Material mit hohen Schall- und Wärmedämmeigenschaften aus Altpapier und/oder Pappe, wobei dieses Ausgangsmaterial -zuerst in wässrige Faserform aufgearbeitet und nach weiterer Verarbeitung geformt und getrocknet wird. Sound and thermal insulation properties from waste paper and / or cardboard " The invention relates to a method for producing material with high sound and thermal insulation properties of waste paper and / or cardboard, this starting material -first worked up in aqueous fiber form and shaped after further processing and is dried.
Ein derartiges Verfahren läßt sich dem japanischen Patent Nr. 55-149183 entnehmen. Hier wird das Ausgangsmaterial nach üblicher Methode naß zerfasert, wobei das Zerschneiden der Papierfasern weitgehend vermieden werden soll. Der so erhaltenen wässrigen Faserdispersion werden anorganische blasige Materialien wie z.B. Perlit zugesetzt. Nach einer Entwässerung und Trocknung des so erhaltenen Gemisches erhält man eine aus miteinander verfilzten Papierfasern und blasigen Mineralien bestehende Masse, die sich ohne Verwendung von Bindemitteln in eine gewünschte Form bringen läßt. Wird das Gemisch in Platten-, Zylinder- oder andere Formen eingespritzt und darin entwässert und getrocknet, so erhält man Schall- und Wärmeisoliermaterialien der jeweils gewünschten Form. Dieses Material besitzt hohe Schall- und Wärmedämmeigenschaften bei niedrigem Gewicht.Such a method can be found in Japanese Patent No. 55-149183 remove. Here the starting material is fiberized wet by the usual method, whereby the cutting of the paper fibers should be largely avoided. The thus obtained aqueous fiber dispersion, inorganic vesicular materials such as perlite are used added. Obtained after dehydration and drying of the mixture thus obtained one made of felted paper fibers and vesicular minerals Masses that can be brought into a desired shape without the use of binders leaves. The mixture is injected into plate, cylinder or other shapes and dehydrated and dried therein, sound and heat insulating materials are obtained the desired shape. This material owns high sound and thermal insulation properties with low weight.
I Der Erfindung liegt die Aufgabe zugrunde, ausgehend von dem eingangs erläuterten Verfahren ein Material herzustellen, mit dem sich die bisher im Bereich des Verpackungswesens eingesetzten Materialien sowie Füll-, Dämm- und Isolierstoffe wie z.B. Papier, Pappen, Styropor, Wellpappe, Glaswolle, Holzwolles Schaumstoffe uOdergl. ersetzen lassen. Denn diese Materialien sind in ihrer Herstellung teuer, meist auch frachtintensiv und lassen eine vielseitige Wiederverwendung bzw. Aufarbeitung meistnicht zu Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die nasse Fasermasse mit Emulgatoren versehen und/oder mechanisch verschäumt und nach einer Vorformung mit einem Konservierungsmittel in Struktur und Form stabilisiert wird. I The invention is based on the object, based on the initially explained process to produce a material with which the previously in the area materials used in packaging, as well as filling, insulating and insulating materials such as paper, cardboard, styrofoam, corrugated cardboard, glass wool, wood wool foams uOdergl. have it replaced. Because these materials are expensive to produce, mostly also freight-intensive and can be reused or reconditioned in a variety of ways mostly not to This object is achieved according to the invention in that the wet Fiber mass provided with emulsifiers and / or mechanically foamed and after a Preforming is stabilized in structure and shape with a preservative.
Dabei kann es zweckmäßig sein, wenn die aufgearbeitete Fasermasse vor ihrer Stabilisierung bei Unterdruck getrocknet wird. It can be useful if the processed fiber mass is dried under reduced pressure before it is stabilized.
Nach dem Sortieren, Vermahlen und Aufweichen des Ausgangsmaterials nach herkömmlichen Methoden wird die homogene Fasermasse im noch nassen Zustand mit Emulgatoren,wie z.B.bei PVC-Scht versehen oder aber mechanisch verschäumt. Die aufgeschäumte Mastse wird dann in Vorformen portioniert und je nach weiterer Ver-Iwendung in einer Unterdruckkammer getrocknet. Durch den an-|schließenden plötzlichen Druckausgleich entstehen schwammartige, leichte und weiche Flocken o.dergl ., die durch Aufsprühen von Oberflächenleim o.dergl. in der angenommenen Struktur und Form stabilisiert werden. Dabei lassen sich durch gezielte Steuerung und Vorformung verschiedene Formen mit unterschiedlichen Härtegraden herstellen.After sorting, grinding and softening the raw material according to conventional methods, the homogeneous fiber mass is obtained when it is still wet with emulsifiers, e.g. provided with PVC-Scht or mechanically foamed. the Foamed masts are then portioned in preforms and depending on their further use dried in a vacuum chamber. Through the subsequent sudden pressure equalization sponge-like, light and soft flakes or the like are created by spraying of surface glue or the like. stabilized in the assumed structure and shape will. Through targeted control and pre-forming, different shapes can be created Manufacture with different degrees of hardness.
Die nach dem erfindungsgemäßen Verfahren hergestellten Formteiles Papierfiocken9 Papp-Maschee-Flocken, Platten, Wände, Behälter o.dergl. sind je nach Verfahrenssteuerung sehr leicht und elastisch, bieten dem zu verpackenden Gut sicheren Schutz und haben zudem hohe Isolier-, Schall- und Wärmedämmeigenschaften. The molded part produced by the process according to the invention Papierfiocken9 Cardboard-Maschee-flakes, plates, walls, containers or the like are very light and elastic, depending on the process control, offer the packaging Good, safe protection and also have high insulation, sound and heat insulation properties.
Außerdem läßt sich das so gewonnene Material stets wieder verwenden; es ist fast staubfrei und daher sehr umweltfreundlich.In addition, the material obtained in this way can always be reused; it is almost dust-free and therefore very environmentally friendly.
Um das neue Material auch schwer entflammbar zu machen, können der Formmasse feuerhemmende Mittel zugesetzt werden.To make the new material flame retardant, you can use the Molding compound fire retardants are added.
