Description
Verfahren -zur Veredlung von Straßenteeren o. dgl. bituminösen Stoffen Das Wesen der Erfindung besteht darin, die Bindefähigkeit und Witterungsfestigkeit von Straßenteeren u. dgl. bituminösen, Stoffen zu verbessern, um dadurch eine weitgehendere Verwendung dieser Stoffe für den Straßenbau zu erzielen. Bislang war nur eine bedingte Verwendung möglich. Insbesondere für Straßen mit großem Verkehr waren die Eigenschaften dieser an sich billigen Baustoffe unzulänglich. ' Man hat nun bereits versucht, die bindenden Eigenschaften von Teer zu verbessern, indem man dem destillierten Teer Montanwachs zugesetzt hat. Ferner hat man auch bereits Harz dem Teer hinzugefügt, wodurch gleichfalls eine Erhöhung der Bindefähigkeit sowie ein; Erhärten angestrebt wurde. Die erzielten Eigenschaften genügten noch nicht ganz den praktischen Forderungen.Process for the refinement of road tars or the like bituminous substances The essence of the invention is the bondability and weather resistance of road tar and the like. Bituminous substances to improve thereby a more extensive Use of these substances for road construction. So far only one has been conditional Use possible. The properties were particularly good for roads with heavy traffic these inherently cheap building materials are inadequate. 'They have already tried improve the binding properties of tar by adding the distilled Tar has added montan wax. Furthermore, resin has already been added to the tar, whereby also an increase in the binding capacity as well as a; Strive for hardening became. The properties achieved did not quite meet the practical requirements.
Das Kennzeichen der Erfindung besteht nun darin, daß als Veredlungsmittel verseiftes und darauf überfettetes Naturharz, insbesondere Kolophonium, verwendet wird.The characteristic of the invention is that as a finishing agent saponified and then over-greased natural resin, especially rosin, is used will.
Durch die Verseifung des Harzes wird die Klebefähigkeit auch bei nassem Untergrund wesentlich erhöht. Da erfahrungsgemäß bei Oberflächenbehandlung es nicht möglich ist, das Gesteinsmaterial ganz trocken zu verarbeiten, so daß demzufolge die Verbindung zwischen Mineral und dem aufgebrachten Straßenteer nie eine innige sein kann, so sind die sich durch die Feuchtigkeit ergebenden Nachteile durch die Erfindung behoben.The saponification of the resin increases the adhesiveness even when it is wet Substantially increased subsoil. Experience has shown that surface treatment does not is possible to process the rock material completely dry, so that accordingly the connection between the mineral and the road tar applied is never intimate can be, the disadvantages resulting from the moisture are due to the Invention fixed.
Die überfettung der Harzseife ergibt den Vorteil, daß ein Auflösen derselben bei langer Lagerung im Wasser vermieden ist.The excess grease of the resin soap has the advantage that it dissolves the same is avoided during long storage in water.
Die Verseifung des Naturharzes richtet sich ganz nach der Beschaffenheit der jeweilig verwendeten Harze. Zur Verwertung gelangt irgendein Naturharz, das beispielsweise mit Natronlauge zu einer ganz dickflüssigen, fadenziehenden, stark klebrigen Masse verseift wird. Die Harzseife wird alsdann mit Anthrazenöl überfettet, so daß ein vollständiges Auflösen der Harzseife bei anhaltendem Regen oder nassem Untergrund vermieden wird. Andererseits geht gerade bei feuchtem Untergrund die Harzseife, in feinster Verteilung dem Straßenteer zugesetzt, mit dem Untergrund eine innige Bindung ein. Die abstoßende Wirkung der Feuchtigkeit des Untergrundes wird von den Seifenpartikelchen vollständig aufgehoben.The saponification of the natural resin depends entirely on its properties the resins used in each case. Any natural resin that for example with caustic soda to a very thick, stringy, strong sticky mass is saponified. The resin soap is then greased with anthracene oil, so that a complete dissolution of the resin soap in persistent rain or wet Underground is avoided. On the other hand, it works especially on a damp surface Resin soap, added to the road tar in the finest distribution, with the subsoil an intimate bond. The repellent effect of the moisture on the sub-floor is completely absorbed by the soap particles.
