Schwer entflammbarer Schlauch Flame retardant hose
Zusatz zu Patent .......... (Patentanmeldung P 26 19 432.1-12) Das Hauptpatent betrifft einen schwer entflammbaren Schlauch, insbes. für die Führung von Warmluft, - bestehend aus Innenmantel, Außenmantel und Kunstharzzwischenschicht (ggf. mit eingebetteter, schraubenförmig umlaufender Drahtarmierung), wobei der Innenmantel einerseits, der Außenmantel andererseits aus Glasfasergewebeband schraubenwendelförmig gewickelt und durch die Kunstharzzwischenschicht in ihrer Wickelnaht sowie miteinander verschweißt sind. Nach dem Hauptpatent weist die Kunstharzzwischenschicht Polyurethan auf und das Glasfasergewebe von Innenmantel und Außenmantel ist als engmaschige Diffusionssperre ausgebildet.Addition to patent .......... (patent application P 26 19 432.1-12) Das The main patent relates to a flame-retardant hose, especially for the guide of warm air, - consisting of inner jacket, outer jacket and synthetic resin intermediate layer (possibly with embedded, helical circumferential wire armouring), whereby the Inner jacket on the one hand, the outer jacket on the other hand made of glass fiber fabric tape in a helical shape wrapped and through the synthetic resin intermediate layer in their wrapping seam and with each other are welded. According to the main patent, the synthetic resin intermediate layer comprises polyurethane on and the fiberglass fabric of the inner jacket and outer jacket is as close-meshed Diffusion barrier formed.
Diffusionssperre bezeichnet dabei ein engmaschiges Gewebe, dessen Maschenweite und Fadenaufbau so gewählt sind, daß auch bei erhöhten und hohen Temperaturen Sauerstoff in einer für die Entzündung der Kunstharzzwischenschicht ausreichenden Menge nicht an die Kunstharzzwischenschicht gelangen kann. Das läßt sich durch Engmaschigkeit und Fadenaufbau für alle Einsatzfälle und Verwendungszwecke erreichen, so daß die nach dem Hauptpatent aufgebauten Schläuche folglich für alle Einsatzfälle und Verwendungszwecke schwer entflammbar ausgelegt werden können. Im Rahmen des Hauptpatentes besteht die Kunstharzzwischenschicht bezüglich des Kunstharzes vollständig aus Polyurethan. Sie kann zusätzlich Beimischungen von unbrennbaren Füllstoffen und eine Beimischung aus Natriumsilizium aufweisen. Den Einsatz von Polyvinylchlorid für die Kunstharzzwischenschicht hat man im Rahmen des Hauptpatentes vollständig vermieden, weil man befürchtete, daß bei höheren und hohen Temperaturen aus dem Chlorgehalt des Polyvinylchlorids bzw. bei der Verbrennung Chlor frei wird, woraus in Anwesenheit von Wasserdampf Salzsäure entsteht, die stark korrodierend und außerdem gesundheitsschädlich ist. Obwohl in der Fachwelt die Auffassung herrscht, daß Polyurethan für schwer entflammbare Gegenstände nicht eingesetzt werden kann, funktioniert im Rahmen des Hauptpatentes überraschenderweise Polyurethan als Kunststoffzwischenschicht, - und zwar wegen der Kombination mit der Diffusionssperre.Diffusion barrier refers to a tightly meshed fabric, its Mesh size and thread structure are chosen so that even at elevated and high temperatures Oxygen in an amount sufficient to ignite the synthetic resin interlayer Amount cannot get to the synthetic resin interlayer. That can be done through tightness and achieve thread structure for all applications and purposes, so that the hoses constructed according to the main patent for all applications and purposes can be designed to be flame-retardant. In the context of the main patent exists the synthetic resin intermediate layer with respect to the synthetic resin made entirely of polyurethane. It can also contain admixtures of non-flammable fillers and an admixture made of sodium silicon. The use of polyvinyl chloride for the synthetic resin intermediate layer has been completely avoided within the framework of the main patent because it was feared that at higher and high temperatures from the chlorine content of the polyvinyl chloride or chlorine is released during combustion, which in the presence of water vapor Hydrochloric acid is formed, which is highly corrosive and also harmful to health. Although in the professional world there is the opinion that polyurethane for flame retardant Objects cannot be used, works within the scope of the main patent Surprisingly, polyurethane as a plastic intermediate layer, - because of the combination with the diffusion barrier.
Demgegenüber geht die Erfindung von der ebenfalls überraschenden Erkenntnis aus, daß bei Einsatz von Diffusionssperren für Innenmantel und Außenmantel auch mit Mischungen von Polyurethan mit Polyvinylchlorid gearbeitet werden kann, wenn die Mischungen gleichzeitig Polyvinylacetat enthalten und. die Beimischung von Polyvinylchlorid nicht zu hoch ist. Gegenstand der Erfindung ist daher gleichsam der allgemeine Erfindungsgedanke des Hauptpatentes, der dadurch gekennzeichnet ist, daß bei Aufbau von Innenmantel und Außenmantel als engmaschige Diffusionssperre die Kunstharzzwischenschicht aus einer Mischung von Polyurethan mit Polyvinylchlorid oder mit Polyvinylacetat besteht. Nach bevorzugter Ausführungsform liegt das Mischungsverhältnis Polyurethan / Polyvinylchlorid oder Polyvinylacetat etwa im Bereich 20-40 Anteile / 10-20 Anteile. Bevorzugte Werte sind etwa 35 Anteile lineares Polyurethan, 16 Anteile Polyvinylchlorid.In contrast, the invention is based on the likewise surprising finding from the fact that when diffusion barriers are used for the inner and outer sheaths too it is possible to work with mixtures of polyurethane with polyvinyl chloride, if the mixtures also contain polyvinyl acetate and. the admixture of polyvinyl chloride is not too high. The subject of the invention is hence, as it were the general inventive concept of the main patent, which is characterized by that when building the inner jacket and outer jacket as a close-meshed diffusion barrier the synthetic resin intermediate layer made of a mixture of polyurethane with polyvinyl chloride or with polyvinyl acetate. According to a preferred embodiment, the mixing ratio is Polyurethane / polyvinyl chloride or polyvinyl acetate in the range of 20-40 parts / 10-20 shares. Preferred values are about 35 parts linear polyurethane, 16 Percentage of polyvinyl chloride.
Auch bei dem erfindungsgemäßen Schlauch kann die Kunstharzzwischenschicht eine Beimischung von unbrennbaren Füllstoffen, insbes. feinkörnigen mineralischen Füllstoffen aufweisen. Auch im Rahmen der Erfindung ist insoweit eine bevorzugte Ausführungsform dadurch gekennzeichnet, daß das Polyurethan eine Beimischung von Natriumsilizium, vorzugsweise in Mengen von 5 bis 25 Anteilen, insbes. in Mengen von 1o Anteilen aufweist.The synthetic resin intermediate layer can also be used in the hose according to the invention an admixture of non-flammable fillers, especially fine-grain mineral ones Have fillers. In this respect, a preferred one is also within the scope of the invention Embodiment characterized in that the polyurethane is an admixture of Sodium silicon, preferably in amounts of 5 to 25 parts, especially in amounts of 1o shares.
Die erreichten Vorteile sind darin zu sehen, daß bei einem erfindungsgemäßen schwer entflammbaren Schlauch zusammen mit Polyurethan auch Polyvinylchlorid und Polyvinylacetat eingesetzt werden können, wobei eine Kunststoffmischung entsteht, die bei der Herstellung des Schlauches leichter verarbeitbar ist als eine Kunststoff zwischenschicht, die vollständig aus Polyurethan aufgebaut ist. Tatsächlich lassen sich bei der Herstellung der Schläuche Mischungen aus Polyurethan mit Polyvinylchlorid und Polyvinylacetat sehr leicht verarbeiten, insbes. leicht miteinander verschweißen.The advantages achieved are to be seen in the fact that in an inventive flame retardant hose together with polyurethane also polyvinyl chloride and Polyvinyl acetate can be used, whereby a plastic mixture is formed, which is easier to process in the manufacture of the hose than a plastic intermediate layer made entirely of polyurethane. Actually let it Mixtures of polyurethane with polyvinyl chloride are used in the manufacture of the hoses and polyvinyl acetate are very easy to process, especially easy to weld together.
Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung ausführlicher erläutert. Es zeigen in schematischer Darstellung Fig. 1 perspektivisch eine Ansicht eines erfindungsgemäßen schwer entflammbaren Schlauches, teilweise aufgeblättert, Fig. 2 den vergrößerten Ausschnitt A aus dem Gegenstand nach Fig. 1 und Fig. 3 den vergrößerten Ausschnitt B aus dem Gegenstand nach Fig. 1.In the following the invention is based on only one embodiment Illustrative drawing explained in more detail.
