Description
Verfahren zur Herstellung eines bituminösen Bindemittels für Straßenbauzwecke und Baustoffe Die Erfindung betrifft ein Verfahren zur Herstellung eines bituminösen Bindemittels für Straßenbauzwecke und Baustoffe. Es ist bekannt, Kunstasphalt aus Teer herzustellen, indem der Teer einem Oxvdations- oder Polymerisationsprozeß durch Behandlung mit Luft oder mit Sauerstoff abgebenden Stoffen unterworfen wird.Process for the production of a bituminous binder for road construction purposes and building materials The invention relates to a method for producing a bituminous Binders for road building purposes and building materials. It is known to be made from artificial asphalt To produce tar by the tar through an oxidation or polymerization process Treatment with air or with oxygen-releasing substances is subjected.
Diese bekannten Verfahren haben den Nachteil, daß sie zum Teil mehrstufig, zum Teil mit hohen Zuschlägen von Sauerstoffüberträgern ausgeführt werden müssen. Außerdem hat sich herausgestellt, daß diese bekannten Oxydationsverfahren sich nicht zur Herstellung eines Bindemittels eignen, das beispielsweise zur Herstellung von Pflasterüberzügen in dünnen Schichten aufgetragen werden muß. In diesem Falle muß das Bindemittel die Eigenschaften einer stark klebrigen plastischen Masse von großer Kohäsion haben; es muß in Verbindung mit anderen Körpern weiter erhärten, ohne jedoch seine Elastizität vollständig zu verlieren.These known methods have the disadvantage that they are sometimes multi-stage, sometimes have to be carried out with high additions of oxygen carriers. In addition, it has been found that these known oxidation processes do not work suitable for the production of a binder, for example for the production of Plaster coatings must be applied in thin layers. In this case it must the binder has the properties of a very sticky plastic mass of great Have cohesion; it must further harden in connection with other bodies, but without to lose its elasticity completely.
Um den Teer in diesen Zustand überzuführen, wird er gemäß der Erfindung erhitzt und mit einer geringen Menge (etwa -2 "/") einer Mineralsäure behandelt, aber nur so lange, bis die Oxydation eingeleitet, aber nicht vollständig durchgeführt worden ist. Von der Menge der zugeführten Säure hängt es somit ab, dem Teer die oben angegebenen Eigenschaften zu geben.In order to bring the tar into this state, it is according to the invention heated and treated with a small amount (about -2 "/") of a mineral acid, but only until the oxidation is initiated, but not completely carried out has been. It therefore depends on the amount of acid added to the tar the to give properties given above.
Gegenüber der Sauerstoffbehandlung hat das neue Verfahren noch den großen Vorteil, daß es in einfacher Weise durchgeführt werden kann. Es genügt ein Durchmischen von heißerri Teer mit Säure in .offenen Gefäßen an der Baustelle; besondere Einrichtungen sind dabei nicht erforderlich.Compared to the oxygen treatment, the new process still has the great advantage that it can be carried out in a simple manner. It is enough Mixing hot tar with acid in open vessels at the construction site; special Facilities are not required.
An sich ist die Behandlung von Teer und Teeröl mit Schwefelsäure bekannt, wie aus der Patentschrift 158 731 hervorgeht. Bei diesem Verfahren werden jedoch io bis ioo °/" Schwefelsäure dem Ausgangsstoff zugesetzt, um aus dem Teer Pech herzustellen. Es bedarf keiner Erörterung, daß der Endzweck dieses Verfahrens ein anderer ist als bei dem neu vorgeschlagenen, und infolgedessen auch bei seiner Durchführung andere Gesichtspunkte beobachtet werden müssen. Bei der Pechherstellung spielt die physikalische Beschaffenheit der Masse keine Rolle, während es sich beim vorliegenden Verfahren gerade darum handelt, der Masse bestimmte physikalische Eigenschaften zu geben.The treatment of tar and tar oil with sulfuric acid is known per se, as can be seen from patent specification 158,731. However, with this procedure 10 to 100% sulfuric acid is added to the starting material to produce pitch from the tar. Needless to say, the end purpose of this procedure is different than with the newly proposed one, and consequently also with its implementation other points of view need to be observed. When it comes to pitch production, that plays a role physical nature of the mass does not matter, while it is with the present Process is about the mass certain physical properties admit.
