Description
Verfahren zur Herstellung von Straßenbindemitteln Steinkohlenteer wird in stets wachsenden Mengen zur Befestigung von Straßendecken verwendet. Der gewöhnliche Steinkohlenteer besitzt an sich nur geringe Klebkraft, und eine Bindung des auf die Straße gebrachten Gesteins durch den Teer tritt erst dann ein, wenn der Teer längere Zeit der Einwirkung der Atmosphäre ausgesetzt war. Daraus entsteht die Gefahr, daß bei zu früher Übergabe solcher mit Teer behandelten Straßen an den Verkehr eine Zerstörung der frischen Straßendecke eintritt. Man hat diesem Übelstand dadurch abzuhelfen gesucht, daß man den gewöhnlichen Steinkohlenteer durch Destillation von den leicht flüchtigen Bestandteilen befreit hat. Auch werden für Straßenbauzwecke Teere verwendet, die durch Auflösen von Steinkohlenteerpech in Anthracenöl besonders hergestellt werden. Schließlich hat man durch Zumischen von Bitumen und anderen klebenden Stoffen, so z. B. Harzen, Fettpechen usw., die Klebkraft des Steinkohlenteers zu heben versucht. Durch alle diese Methoden wird aber der beabsichtigte Zweck nur unvollkommen erreicht; insbesondere tritt durch die Zumischung der fremden Stoffe zum Teer eine starke Verdickung des Teers ein, die seine Anwendung erschwert.Process for the production of road binders Coal tar is used in ever increasing quantities for paving road surfaces. Of the Ordinary coal tar itself has only low adhesive strength and a bond of the rock brought onto the road by the tar only occurs when the tar has been exposed to the atmosphere for a long time. That turns into the risk that if such tar-treated roads are handed over too early to the Traffic a destruction of the fresh road surface occurs. You have this evil sought to remedy this by distilling the ordinary coal tar has freed from the volatile components. Also be used for road construction purposes Tars used by dissolving coal tar pitch in anthracene oil especially getting produced. After all, you have by adding bitumen and others adhesive materials, such as B. resins, grease pitch, etc., the adhesive strength of coal tar tried to lift. However, all of these methods only achieve the intended purpose imperfectly achieved; in particular occurs through the admixture of foreign substances a strong thickening of the tar makes it difficult to use.
Es wurde nun gefunden, daß man durch Behandlung von Steinkohlenteer, und zwar sowohl sogenanntem destillierten Teer als auch Anthracenölteer, mit Chlor eine bedeutende Erhöhung der Klebkraft des Teers erreichen kann, ohne daß eine im Verhältnis zur Zunahme der Klebkraft stehende Verdickung des Teers erfolgt. Die Behandlung des Teers mit Chlor kann in der Weise erfolgen, daß man Chlorgas in den Teer einleitet. Man kann aber auch die Chlorbehandlung so ausführen, daß man dem Teer Chlor entwickelnde Stoffe, so z. B. Chlorkalk oder unterchlorigsaures Alkali, Chloramin usw., zumischt. In diesem Falle tritt in der Masse zunächst keine Verdickung ein. Die Verdickung und Erhöhung der Klebkraft erfolgt erst dann, wenn der mit Chlor entwickelnden Stoffen vermischte Teer in so dünner Schicht, wie er auf den Straßen angewendet wird, der Einwirkung der Atmosphäre ausgesetzt wird. Hierbei nimmt der Teer in erheblich kürzerer Zeit eine das aufgebrachte Gestein bindende Klebkraft an als der gewöhnliche Straßenteer und auch der mit klebenden Stoffen vermischte Teer. Man ist nach diesem Verfahren in der Lage, Teeren, die von Haus aus oder durch Zusatz von Lösungsmitteln so flüssig sind, daß sie ohne Erwärmung auf die Straße gebracht werden können, eine derartige Bindekraft zu verleihen, daß die damit behandelten Straßen schnellstens dem Verkehr übergeben «-erden können.It has now been found that by treating coal tar, both so-called distilled tar and anthracene oil tar, with chlorine can achieve a significant increase in the bond strength of the tar without an im Thickening of the tar takes place in relation to the increase in bond strength. the Treatment of the tar with chlorine can be done in such a way that chlorine gas in the Introduces tar. But you can also carry out the chlorine treatment so that the Tar, chlorine-evolving substances, e.g. B. chlorinated lime or hypochlorous alkali, Chloramine, etc., admixed. In this case, there is initially no thickening in the mass a. The thickening and increase of the bond strength only takes place when the chlorine Tar mixed with developing substances in as thin a layer as it is on the streets is used, exposed to the action of the atmosphere. Here the Tar has an adhesive force that binds the applied rock in a considerably shorter time on than the common road tar and also that mixed with sticky materials Tar. According to this method, one is able to tarring, either by or at home Adding solvents are so liquid that they hit the street without heating can be brought to impart such a binding force that the treated with it Roads can be handed over to traffic as quickly as possible.
Beispiel In 30 ooo kg, auf 6o bis 7o° erwärmten Straßenteer (6o/4o Anthracenteer) werden in einem geschlossenen Rührwerk z 5o kg Chlor unter Rühren eingeleitet.Example In 30,000 kg of road tar heated to 6o to 7o ° (6o / 4o Anthracite tar) z 50 kg of chlorine are stirred in a closed stirrer initiated.
Der Prozeß ist in etwa 2 Stunden beendet. Der so erhaltene Teer wird in heißem Zustand als Bindemittel im Straßenbau verwendet. Wenn er kalt aufgetragen werden soll, ist er vorher mit geeigneten Lösungsmitteln in Mengen von zo bis 15 °(o zu verdünnen.The process is completed in about 2 hours. The tar thus obtained becomes in hot condition used as a binder in road construction. if If it is to be applied cold, it has to be cleaned beforehand with suitable solvents Quantities from zo to 15 ° (o to be diluted.
Es ist bereits vorgeschlagen worden, Kohlenwasserstoffe und Rückstände aus Rohpetroleum mit Chlor zu behandeln. Abgesehen davon, daß es sich hierbei um Rohstoffe handelt, die vom Steinkohlenteer chemisch durchaus verschieden sind, führt jenes Verfahren auch nicht zu flüssigen teerartigen Erzeugnissen, sondern zu hartem asphaltartigem Bitumen. Auch eine Behandlung von Teer mit Chlorschwefel führt zu harten, für den vorliegenden Zweck unbrauchbaren geschwefelten Erzeugnissen. Das gleiche ist der Fall bei der Verarbeitung von Steinkohlenteerpech mit Chlorkalk und Schwefel. Die aus Steinkohlenteeröl und Chlor erhaltenen 51e sind wohl als Holzkonservierungsmittel, nicht aber als Bindemittel im Straßenbau verwendbar. Ebensowenig eignen sich die aus Teer in Gegenwart ungesättigter Fettsäureester mit Hexachloräthan hergestellten Anstrichtrfiittel für den Zweck der vorliegenden Erfindung.It has been suggested before, hydrocarbons and residues to treat crude petroleum with chlorine. Apart from the fact that this is It deals with raw materials that are chemically quite different from coal tar that process does not lead to liquid tarry products either, but to hard ones asphalt-like bitumen. Treating tar with chlorinated sulfur also leads to hard sulphurized products unsuitable for the present purpose. That the same is the case with the processing of coal tar pitch with chlorinated lime and sulfur. The 51e obtained from coal tar oil and chlorine are probably used as wood preservatives, but not usable as a binding agent in road construction. They are just as unsuitable made from tar in the presence of unsaturated fatty acid esters with hexachloroethane Paints for the purpose of the present invention.
