Description
Die Erfindung betrifft einen Kompressorschlauch, der öl- und temperaturbeständig und schwer entflammbar ist, zur Vermeidung von Kompressorbränden bei stationärem Einsatz.The invention relates to a compressor hose that is oil and temperature resistant and flame retardant to prevent compressor fires during stationary use.
Es sind Kompressorschläuche bekannt, die zur Vermeidung von Kompressorbränden schwer entflammbar ausgebildet sind, hierbei jedoch Umhüllungen zur Brandverraeidung aufweisen, die nach heutigem Wissensstand als toxikologisch bedenklich einzustufen sind.Compressor hoses are known that are designed to be flame-retardant to prevent compressor fires, but have fire-retardant coatings that, according to current knowledge, are classified as toxicologically questionable.
Bekannt sind unter anderem Umhüllungen aus Zellwollbeimischungen von 15 bis 20 % bei Keramikfaser garnen und deren Endprodukten. Hierbei ergaben sich hohe Glühverluste mit zum Teil belästigender Rauchbildung und entsprechendem Materialschwund.Among other things, coatings made of rayon blends of 15 to 20% in ceramic fiber yarns and their end products are known. This resulted in high ignition losses with sometimes unpleasant smoke formation and corresponding material shrinkage.
Ferner sind organische Umlagen aus einem Kondensationsprodukt aus Isophthalsäure und m-Phenylendiamin sowie ein Kondensationsprodukt aus Terephthalsäure und p-Phenylendiamin und Zwirne 4»us oxidiertem PoIyacrylmethyl bekannt, die jedoch eine nur geringe Wärmeleitfähigkeit, d.h. ein^ niedrige Temperaturabführungsgeschwindigkeit aufweisen.Furthermore, organic coatings made from a condensation product of isophthalic acid and m-phenylenediamine as well as a condensation product of terephthalic acid and p-phenylenediamine and threads made from oxidized polyacrylmethyl are known, but these have only a low thermal conductivity, i.e. a low temperature dissipation rate.
Umlagen au j Koh lemtof f-Fasern weisen eine geringe Querfestigkeit auf und sind dabei sehr kostspielig.Layers made of carbon fibers have low transverse strength and are very expensive.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Kompressorschlauch der eingangs genannten Gattung bereit zu stellen, der eine Umlage aufweist, die nur schwer entflammbar ist und dabei toxikologisch unbedenklich ist.The invention is therefore based on the object of providing a compressor hose of the type mentioned at the beginning, which has a cover that is difficult to ignite and is toxicologically harmless.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der schwer entflammbare öl- und temperaturbeständige, aus mehreren Schichten bestehende Kompressorschlauch mit einer dauerbeständigen Umlage dadurch gekennzeichnet ist, daß der Schlauch aus einer Seele aus Ehtylen-Acryl-Elastomer, einem die Seele umgebender ersten Stahlgeflecht, einer das Stahlgeflecht umgebenden Trennplatte aus Ethylen-Acryl-Elastomer, einer die Trennplatte umgebenden Stahlspirale, einem die Spirale umgebenden zweiten Stahlgeflecht, einer das Stahlgeflecht und einer Decke aus Ethylen-Acryl-Elastomer verbindenden Lösung und einer Umlage aus Kalzium-Silicat-Fasern, Keramikgarn oder Glasfaserzwirn besteht, wobei die Umlage die darunter angeordneten Schichten abschließend umgibt.This object is achieved according to the invention in that the flame-retardant, oil- and temperature-resistant compressor hose consisting of several layers with a durable coating is characterized in that the hose consists of a core made of ethylene-acrylic elastomer, a first steel braid surrounding the core, a separating plate made of ethylene-acrylic elastomer surrounding the steel braid, a steel spiral surrounding the separating plate, a second steel braid surrounding the spiral, a solution bonding the steel braid and a cover made of ethylene-acrylic elastomer and a coating made of calcium silicate fibers, ceramic yarn or glass fiber thread, the coating finally surrounding the layers arranged underneath.
