Description
Insbesondere für Tankstellen bestimmter, elektrisch leitfähiger Schlauch Von Schläuchen, die zum Hindurchleiten von feuergefährlichen Flüssigkeiten, wie Benzin, Benzol u. dgl., bestimmt sind, z. B. von Tankstellen-und Tankwagenschläuchen, wird verlangt, daß sie elektrisch leitfähig sind, damit entstehende elektrostatische Aufladungen des Schlauches unschädlich werden. Die bekannten Tankstellenschläuche enthalten zu diesem Zweck eine Einlage aus Metall.Electrically conductive hose designed especially for petrol stations From hoses that are used to pass flammable liquids, such as Gasoline, benzene and the like, are intended, e.g. B. of gas station and tank truck hoses, it is required that they are electrically conductive, thus resulting electrostatic Charges on the hose become harmless. The well-known gas station hoses contain a metal insert for this purpose.
Es läßt sich nun an Tankstellen nicht vermeiden, daß die Schläuche gelegentlich von den Kraftfahrzeugen überfahren werden oder daß sie geknickt werden. In diesen Fällen werden die Schläuche für ihre weitere Verwendung als Tankstellenschlauch unbrauchbar. Der Bedarf an Ersatzschläuchen für Tankstellen ist daher außerordentlich groß.It can now not be avoided at gas stations that the hoses are occasionally run over by the motor vehicles or that they are kinked. In these cases the hoses are used for further use as a gas station hose unusable. The need for replacement hoses for petrol stations is therefore extraordinary great.
Die Erfindung schafft einen metallosen Schlauch, der knick- und bruchfest ist, dem es also nicht schadet, wenn er überfahren wird, und der die geforderte elektrische Leitfähigkeit stets beibehält, auch wenn der Schlauch gequollen ist. The invention creates a metal-less hose that is kink and break-proof is, which it does not harm if it is run over, and the one that is required always maintains electrical conductivity, even if the hose is swollen.
Nach der Erfindung sind in den metallosen, im wesentlichen aus synthetischem Gummi bestehenden Schlauch bleihaltiges Metalloxyd, vorzugsweise Zinkoxyd mit etwa 60/o Bleigehalt, ferner leitfähiger Acetylen-, Gas- oder Flammruß und Dithriodiglycolsäure - dibutyl - ester als Weichmacher eingelagert. According to the invention are in the metallose, essentially synthetic Rubber hose made of leaded metal oxide, preferably zinc oxide with about 60 / o lead content, also conductive acetylene, gas or flame black and dithriodiglycolic acid - dibutyl - ester incorporated as a plasticizer.
Es ist bekannt, bei metallosen, im wesentlichen aus synthetischem Gummi bestehenden Schlauchwerkstoffen Metalloxyde einzulagern. Weiterhin ist die Einlagerung von Bleipulver bekannt gewesen. Schließlich gehört es auch zum Stand der Technik, leitfähige Kautschukmischungen durch Beimengung von Ruß herzustellen. Demgegenüber besteht die Erfindung in der Kombination folgender jeweils für sich bekannter Einzelmerkmale: a) daß bleihaltiges Metalloxyd, vorzugsweise Zinkoxyd mit etwa 6°/o Bleigehalt, eingelagert wird; b) daß leitfähiger Acetylen-, Gas- oder Flammruß eingelagert wird; c) daß ein bestimmter Weichmacher, nämlich Dithriodiglycolsäure-dibutyl-ester, verwendet wird. It is known to be metalless, essentially synthetic Rubber to store metal oxides in existing hose materials. Furthermore, the Storage of lead powder has been known. After all, it is also part of the stand the technology of producing conductive rubber compounds by adding carbon black. In contrast, the invention consists in the combination of the following in each case known individual features: a) that lead-containing metal oxide, preferably zinc oxide with about 6 ° / o lead content, is stored; b) that conductive acetylene, gas or Lampblack is stored; c) that a certain plasticizer, namely dithriodiglycolic acid dibutyl ester, is used.
Für die Einzelmerkmale oder Teilkombinationen wird kein Schutz begehrt. No protection is sought for the individual features or partial combinations.
Der durch diese Kombination erreichte wesentliche Fortschritt besteht darin, daß die elektrische Leitfähigkeit des Schlauches unter allen Umständen erhalten bleibt, insbesondere auch unter dem Einfluß quellender Substanzen, wie z. B. eines Benzin-Benzol-Gemisches im Verhältnis 50 :50. The substantial advance achieved by this combination remains in that the electrical conductivity of the hose is preserved under all circumstances remains, especially under the influence of swelling substances such. B. one Gasoline-benzene mixture in a ratio of 50:50.
Die Schaffung solcher bisher nicht bekannt gewesener Schläuche hat für Tankstellen außerordentlich große Bedeutung.The creation of such previously unknown hoses has extremely important for petrol stations.
Eine Druckschrift, die sich mit der Beimengung von Ruß bei der Herstellung von leitfähigen Kautschukmischungen befaßt, erwähnt lediglich Olruße. tDlruße sind aber für quellfeste, elektrisch leitfähige Tankstellenschläuche nicht verwendbar, weil diese Ruße den Quellungsprozeß sehr ungünstig beeinflussen und bei stärkerer Quellung der zulässige Höchstwert des elektrischen Widerstandes überschritten wird. Nach der Erfindung werden Acetylenruß, Gasruß oder Flammruß verwendet. A publication dealing with the addition of soot during manufacture concerned with conductive rubber compounds, only mentions oil black. are greetings but cannot be used for swell-resistant, electrically conductive gas station hoses, because these soot have a very unfavorable effect on the swelling process, and if it is stronger Swelling the maximum permissible value of the electrical resistance is exceeded. According to the invention, acetylene black, gas black or flame black are used.
Bei Schläuchen, die aus einem Textilgeflecht, das beiderseitig eine Schicht synthetischen Gummis trägt, bestehen, sind nach der Erfindung sowohl in die Innenschicht als auch in die Außenschicht bleihaltiges Metalloxyd, leitfähiger Ruß und der genannte Weichmacher eingelagert. Bei den handelsüblichen Schlauchkupplungen wird nicht mit Sicherheit eine elektrisch leitende Verbindung der Gummiinnenschichten und eine gleiche Verbindung der Gummiaußenschichten erreicht. In the case of hoses made of a textile braid, one on both sides Layer wearing synthetic rubbers, exist, are according to the invention both in the inner layer and the outer layer contain leaded metal oxide, more conductive Soot and the named plasticizer are incorporated. With the commercially available hose couplings there will not be an electrically conductive connection between the inner rubber layers and achieved an equal connection of the rubber outer layers.
Bei dem Schlauch nach der Erfindung läßt sich demgegenüber bei Verwendung geeigneten Textilgeflechtes erreichen, daß die Gummiinnen- und die Gummiaußenschicht durch die Maschen des Textilgeflechtes hindurch sich verbinden und ineinander übergehen, also einen zusammenhängenden elektrischen Leiter bilden.In contrast, when using the hose according to the invention A suitable textile braid that the rubber inner and the rubber outer layer connect through the meshes of the textile braid and merge, thus form a coherent electrical conductor.
Bei dem neuen Schlauch beträgt der elektrische Widerstand, auf die handelsübliche Schlauchlänge, z. B. 3,50 oder 4,20m, gerechnet, weniger als 106 Ohm, auch im gequollenen Zustand, wie er sich beim Durchfließen von Benzin-Benzol-Gemisch oder bei Gasöl ergibt. The electrical resistance of the new hose is to which commercial hose length, e.g. B. 3.50 or 4.20m, calculated, less than 106 Ohm, even in the swollen state, as it is when flowing through a gasoline-benzene mixture or in the case of gas oil.
