Titel der Erfindung:Title of the invention: Dämmstoff aus Stroh und SchaumstoffInsulation made of straw and foam Gegenstand der Erfindung:Subject of the invention:

Gegenstand der Erfindung ist ein Dämmstoff aus geschäumtem Kunststoff mit einem hohen Anteil an Stroh oder anderen pflanzlichen Fasern mit besonderen wärmedämmenden Eigenschaften in unterschiedlichen Anwendungsformen, beispielsweise als Dämmplatte oder als Ortdämmstoff.The subject of the invention is an insulating material made of foamed plastic with a high proportion of straw or other plant fibers with special thermal insulation properties in different application forms, for example as an insulating board or as an on-site insulation material.

Merkmale der Erfindung:Features of the invention:

Die Erfindung beinhaltet die homogene Einlagerung von gemahlenem oder auf andere Weise zerkleinertem Stroh oder anderen pflanzlichen Fasern mit besonderen wärmedämmenden Eigenschaften in die Schaumstruktur eines Kunststoffes, so daß bei nur geringfügiger Änderung der Dämmeigenschaften gegenüber dem geschäumten reinen Kunststoff die Festigkeit des ausgehärteten Produkts erhöht und gleichzeitig eine Schimmelbildung an den Fasern bzw. eine biologische Zersetzung auf andere Weise verhindert wird.The invention involves the homogeneous incorporation of ground or otherwise shredded straw or other plant fibers with special heat-insulating properties into the foam structure of a plastic, so that with only a slight change in the insulating properties compared to the foamed pure plastic, the strength of the cured product is increased and at the same time mold formation on the fibers or biological decomposition is prevented in another way.

Ausfuhrungsbeispiel:Example:

Der Dämmstoff wird nachstehend an einem möglichen Beispiel beschrieben:
Bei Verwendung eines Polyurethanschaum-Dämmstoffs wird gemahlenes Stroh maschinell in das vorbereitete flüssige PU-System eingebracht. Innerhalb der Reaktionszeit des PU-Systems erfolgt die Austragung auf ein laufendes Band. Das laufende Gut kann beidseitig mit unterschiedlichen flexiblen Materialien kaschiert werden, indem das Gut zusammen mit der Kaschierung durch auf Höhe eingestellte Walzen geführt wird. Die vollständige Aushärtung erfolgt nach dem WalzendurchlaufThe insulation material is described below using a possible example:
When using a polyurethane foam insulation material, ground straw is mechanically introduced into the prepared liquid PU system. The material is discharged onto a moving belt within the reaction time of the PU system. The moving material can be laminated on both sides with different flexible materials by guiding the material together with the lamination through rollers set to the right height. Complete curing takes place after the rollers have passed through it.
