Description

  

  Verfahren zur Herstellung von Asphaltlösungen.    Gegenstand er Erfindung ist ein Ver  fahren zur Herstellung von Asphaltlösungen  unter Verwendung von benzinunlöslichem  Naturasphalt und flüchtigen Lösungsmitteln.  Das Verfahren ist dadurch gekennzeichnet,  dass als wesentlicher Bestandteil des Lösungs  mittels Benzine verwendet werden, ,denen  geringe Mengen flüchtiger     karbonyltragen-          der    Verbindungen zugesetzt werden, die an  sich Naturasphalt nicht lösen.

   Die Möglich  keit, anstatt der bisher zum Lösen von  Naturasphalt gebräuchlichen     Benzolkohlen-          wasserstoffe        Paraffinkohlenwasserstoffe    ver  wenden zu können,     bietet    vor allem :den Vor  teil, dass die Benzinlösungen höheren Ge  brauchswert besitzen, da die     entwickelten     Dämpfe im Gegensatz zu     Benzollösungen     nicht giftig sind. Die gemäss dem vorliegen  den Verfahren erhaltenen Naturasphalt  lösungen können in gewohnter Weise Ver  wendung finden, zum Beispiel als Anstrich-,  Binde- oder Imprägniermittel.

   Selbstver-         ständlich    können die dabei verwendeten Lö  sungen die gebräuchlichen Zusätze, zum  Beispiel Pigmente,     Füllmittel,    trocknende  Öle, Harze und dergleichen, sowie noch an  dere übliche Lösungsmittel enthalten.  



  Im folgenden werden einige Beispiele zur  Ausübung des Verfahrens angeführt:  Man löst 20 bis 40 Gewichtsteile Natur  asphalt in     Lösungsmittelgemischen,    welche  bestehen aus:

  Process for the production of asphalt solutions. The object of the invention is a process for the production of asphalt solutions using gasoline-insoluble natural asphalt and volatile solvents. The method is characterized in that gasoline is used as an essential component of the solution, to which small amounts of volatile carbonyl-bearing compounds are added that do not dissolve natural asphalt.

   The option of using paraffinic hydrocarbons instead of the benzene hydrocarbons previously used to dissolve natural asphalt offers above all: The advantage that the gasoline solutions are more useful because the vapors that are developed are not toxic, in contrast to benzene solutions. The natural asphalt solutions obtained according to the present process can be used in the usual way, for example as a paint, binding agent or impregnating agent.

   Of course, the solutions used here can contain the customary additives, for example pigments, fillers, drying oils, resins and the like, as well as other customary solvents.



  In the following some examples for the implementation of the process are given: 20 to 40 parts by weight of natural asphalt are dissolved in solvent mixtures, which consist of:
