Description
Die vorliegende Erfindung betrifft einen Dämmstoff, der beispielsweise in der Bautechnik zum Dämmen und Isolieren eingesetzt werden kann.The present invention relates to an insulating material, for example can be used in construction technology for insulation and insulation.
Es ist bereits versucht worden, Ligninsulfonat als Bindemittel für Spanplatten zu verwenden. Um eine Bindewirkung zu erzeugen, hat sich dabei der Einsatz höherer Temperaturen und Preßdrücke als notwendig erwiesen.It has been tried to use lignin sulfonate as a binder To use chipboard. To create a binding effect, has the use of higher temperatures and pressures than necessary proven.
Als Dämmstoffe wurden bisher überwiegend Platten und dergleichen aus Schaumkunststoffen eingesetzt. Es sind auch schon Gerüstpolysaccharide, wie z. B. Stroh und dergleichen, mit Bindmittel, wie Zement, zu Dämm stoffplatten verarbeitet worden. Dies Platten sind relativ schwer, während Schaumkunststoffe relativ teuer und wenig umweltfreundlich sind.So far, mainly slabs and the like have been used as insulation Foam plastics used. There are also scaffold polysaccharides, such as B. straw and the like, with binders such as cement to insulation fabric panels have been processed. These plates are relatively difficult while foam plastics are relatively expensive and not very environmentally friendly are.
Aufgabe der vorliegenden Erfindung ist, einen Dämmstoff zu schaffen, der weitgehend aus Naturstoffen bzw. deren Derivaten besteht, der dadurch umweltfreundlich ist und trotz Einsatz billiger Abfall stoffe ein niedriges Raumgewicht aufweist. Gelöst wird diese Aufgabe durch eine Dämmstoff gemäß dem Kennzeichen des Hauptanspruchs. Der Verfahrenshauptanspruch gibt ein Verfahren zur Herstellung des Dämmstoffs an, die Unteransprüche betreffen bevor zugte Ausgestaltungen der Erfindung.The object of the present invention is to provide an insulating material which consists largely of natural products or their derivatives, which is therefore environmentally friendly and despite the use of cheap waste fabrics has a low density. This task is solved by an insulating material according to the label of the main claim. The main claim gives a procedure for Production of the insulation material, the subclaims relate to before preferred embodiments of the invention.
Überraschenderwiese entfaltet in den erfindungsgemäßen Dämmstoffen das Ligninsulfonat seine Bindungswirkung, ohne daß es dazu den Einsatz von erhöhten Temperaturen oder Druck erforderlich macht. Die erfindungsge mäßen Dämmstoffmischungen sind schon unter Umgebungsbedingungen nach wenigen Stunden so weit ausgehärtet, daß sie beim Herausnehmen aus den Formen transportfähig sind.Surprisingly, this unfolds in the insulation materials according to the invention Ligninsulfonat its binding effect without the use of elevated temperatures or pressure. The fiction moderate insulation mixtures are already under environmental conditions hardened within a few hours so that when you take it out the forms are transportable.
Als Ligninsulfonate lassen sich alle wasserlöslichen Ligninsulfonate verwenden. Das sind insbesondere Calcium-, Natrium-, Ammonium- und oder Magnesium-Ligninsulfonat. Sie werden der Mischung aus Gerüst polysaccharid und Altpapier bzw. Spuckstoff in Mengen von ca. 1 bis 30 Gew.-%, bezogen auf das Gewicht der genannten Mischung, zugesetzt. All water-soluble lignin sulfonates can be used as lignin sulfonates use. These are especially calcium, sodium, ammonium and or magnesium lignin sulfonate. They become the mix of scaffolding polysaccharide and waste paper or rejects in quantities of approx. 1 to 30 % By weight, based on the weight of the mixture mentioned, added.
Dabei wird das Ligninsulfonat bevorzugt in wäßriger Lösung aufge sprüht, wobei die wäßrigen Lösungen bevorzugt einen Gehalt von 1 bis 30 Gew.-% Ligninsulfonat aufweisen.The lignin sulfonate is preferably applied in aqueous solution sprayed, the aqueous solutions preferably having a content of 1 to Have 30 wt .-% lignin sulfonate.
Als Gerüstpolysaccharide eignen sich nahezu alle faserigen landwirt schaftlichen Abfälle, wie beispielsweise Holzspäne, Stroh, Flachs, Raps, Baumwollstroh, Kokosfasern, aber auch andere faserige Stoffe, ins besondere Abfallstoffe. Die Gerüstpolysaccharide tragen mit zur Festigkeit und zum Zusammenhalt der Dämmstoffe bei.Almost all fibrous farmers are suitable as scaffold polysaccharides waste, such as wood shavings, straw, flax, rapeseed, Cotton straw, coconut fibers, but also other fibrous materials, ins special waste materials. The scaffold polysaccharides contribute to Strength and cohesion of the insulation materials.
Die Gerüstpolysaccharide werden vorzugsweise auf eine Faserlänge von ca. 1 bis 5 cm zerkleinert.The framework polysaccharides are preferably made to a fiber length of crushed approx. 1 to 5 cm.
Die zweite Mischungskomponente, die aus Altpapier bzw. Spuckstoff besteht, führt zu einer wesentlichen Gewichtsverminderung des Dämm stoffs. Spuckstoff ist ein Gemisch, das im wesentlichen aus Zellstoff fasern und Lignin besteht, das bei der Zellstoffherstellung als Abfall produkt anfällt.The second component of the mixture, made of waste paper or rejects exists, leads to a substantial reduction in the weight of the insulation fabric. Reject is a mixture that consists essentially of cellulose fibers and lignin, which is a waste in pulp production product arises.
Das Altpapier wird bevorzugt zerfasert oder gemahlen, wobei es bis auf eine Teilchengröße von etwa 0,1 bis 5 mm zerkleinert wird.The waste paper is preferably shredded or ground, with the exception of a particle size of about 0.1 to 5 mm is crushed.
Das Mengenverhältnis von Gerüstpolysaccharid zu Altpapier bzw. Spuck stoff beträgt vorzugsweise 90 bis 20 zu 10 bis 90 Gew.-%. Bevorzugt besteht die Mischung aus 30 bis 60 Gew.-% Gerüstpolysaccharid und 40 bis 70 Gew.-% Altpapier bzw. Spuckstoff.The quantity ratio of framework polysaccharide to waste paper or spit Material is preferably 90 to 20 to 10 to 90 wt .-%. Prefers the mixture consists of 30 to 60 wt .-% framework polysaccharide and 40 to 70% by weight of waste paper or rejects.
Der Dämmstoff kann zusätzlich weitere übliche Zusatzstoffe enthalten, so beispielsweise anorganische Stoffe, die insbesondere zur Flamm hemmung zugesetzt werden. Solche Stoffe sind u. a. Ton, Lehm, Kalk, wie Löschkalk oder Traßkalk, Zement, Quarzsand, Glasfasern oder Mineralfasern. Überraschenderweise bleibt auch beim Zusatz solcher anorganischer Stoffe die Bindemittelwirkung des Ligninsulfonats erhalten.The insulation material can also contain other customary additives, So for example inorganic substances, in particular to the flame inhibition can be added. Such substances are a. Clay, clay, lime, such as hydrated lime or lime, cement, quartz sand, glass fibers or Mineral fibers. Surprisingly, the addition of such remains inorganic substances the binding effect of lignin sulfonate receive.
Die erfindungsgemäßen können hergestellt werden, indem zunächst das Gertistpolysaccharid mit dem Altpapier bzw. dem Spuckstoff trocken vermischt wird. Auf das Gemisch wird dann eine wäßrige Lösung des Ligninsulfonats aussprüht. Als wäßrige Lösung des Ligninsulfonats werden Lösungen eingesetzt, die etwa 10 bis 40 Gew.-% Ligninsulfonat enthalten.The inventive can be prepared by first Gertistpolysaccharide with the waste paper or the rejects dry is mixed. An aqueous solution of the Sprayed lignin sulfonate. As an aqueous solution of the lignin sulfonate Solutions used that contain about 10 to 40 wt .-% lignin sulfonate.
Die weiteren Zusatzstoffe, wie anorganische Flammhemmer, können ent weder in das Trockengemisch aus Altpapier bzw. Spuckstoff und Gerüst polysaccharid eingemischt werden oder als Suspension oder Lösung in die wäßrige Lösung des Ligninsulfonats eingegeben werden, die auf die Mischung aufgesprüht wird.The other additives, such as inorganic flame retardants, can ent neither in the dry mixture of waste paper or rejects and framework polysaccharide can be mixed in or as a suspension or solution in the aqueous solution of lignin sulfonate can be entered on the Mixture is sprayed on.
Nach dem Aufsprühen der Ligninsulfonatlösung auf die Mischung aus Gerüstpolysaccharid und Altpapier bzw. Spuckstoff wird die gesamte Mischung in Hohlformen überführt und darin ohne Anwendung von Druck und Temperatur aushärten gelassen. Die Mischungen sind spätestens nach 24 Stunden so formstabil, daß sie transportiert werden können, härten aber noch einige Tage nach.After spraying the lignin sulfonate solution onto the mixture Scaffold polysaccharide and waste paper or rejects become the whole Mixture transferred into hollow forms and therein without the application of pressure and Allow temperature to harden. The mixtures are after at the latest 24 hours so stable that they can be transported, harden but still a few days after.
Die Dämmstoffe sind formstabil, d. h., daß sie auch unter Druck belastung ihre Form nicht verändern. Für den Einsatz als Dämmkörper ist die Formstabilität durchaus hinreichend. Sie können beispiels weise gesägt werden, halten also auch Scherkräften in einem für Dämmkörper hinreichenden Maße stand.The insulation materials are dimensionally stable, i.e. that is, they are also under pressure load do not change shape. For use as an insulating body the dimensional stability is quite sufficient. You can, for example sawn wisely, therefore also consider shear forces in one Insulation body sufficient dimensions.
Ihre Rohdichte beträgt etwa 150 bis 250 kg/m3, insbesondere sogar nur 150 bis 200 kg/m3, ist also der Rohdichte von Schaumstoffdämmstoffen durchaus vergleichbar.Their bulk density is about 150 to 250 kg / m 3 , in particular even only 150 to 200 kg / m 3 , so it is quite comparable to the bulk density of foam insulation materials.
