Description

Verfahren zur Herstellung von Naturasphaltlösungen Gegenstand- der -Erfindung ist das Lösen von benzinunläslichem Naturasphalt in Lösungsmittelgemischen, welche Benzine als wesentlichen Bestandteil enthalten und außerdem geringe Mengen von flüchtigen, mindestens eine Ketogruppe tragenden Verbindungen, welche allein Asphalt nicht zu lösen vermögen. Die Möglichkeit, anstatt der bisher zum Lösen. von Naturasphalt gebräuchlichen Benzolkohlenwasserstoffe ParaffInkohlenwasserstoffe verwenden zu können, bietet vor allem den Vorteil, daß die aus Benzinlösungen entwickelten Dämpfe nicht giftig sind. Die gemäß der Erfindung erhaltenen Naturasphaltlösungen können in gewohnter Weise Verwendung Enden, z. B. als Anstrich-, Binde- -der Imprägniermittel. Selbstverständlich können die dabei verwendeten Lösungen die gebräuchlichen Zusätze, z. B. Pigmente, Füllmittel, trocknende öle, Harze u. dgl., sawie die üblichen Lösungsmittel enthalten.Process for the production of natural asphalt solutions -Invention is the dissolving of gasoline-insoluble natural asphalt in solvent mixtures, which contain petrol as an essential component and also small amounts of volatile compounds containing at least one keto group, which alone Unable to loosen asphalt. The possibility to solve instead of the previous one. Benzene hydrocarbons commonly used in natural asphalt, paraffin hydrocarbons being able to use offers the main advantage that those developed from gasoline solutions Vapors are not toxic. The natural asphalt solutions obtained according to the invention can use ends in the usual way, e.g. B. as a paint, binding agent - the impregnating agent. Of course, the solutions used can contain the usual additives, z. B. pigments, fillers, drying oils, resins and the like, as well as the usual solvents contain.

Man hat schon vorgeschlagen, Gilsonitasphalt benzinlöslich zu machen, jedoch erfolgte dies nicht durch Zusätze zum Benzin, sondern durch Erhitzen des Asphalts auf i6o bis 2o5° während mindestens einer halben Stunde.It has already been suggested to make gilsonitasphalt gasoline-soluble, however, this was not done by adding to gasoline, but by heating the Asphalt at 16o to 2o5 ° for at least half an hour.

Im folgenden werden einige Beispiele zur Ausübung des Verfahrens gemäß der Erfindung angeführt.The following are some examples of practicing the method in accordance with of the invention.

Man löst 2o bis 4o Gewichtsteile Naturasphalt-- in Lösungsmittelgemischen, welche bestehen aus: - i. 95 Gewichtsprozenten Benzin, 5 - Aceton; 2.94 - Benzin, 6 - Acetophenon; 3.96 - Benzin, 4 - i # i # 3-Trimethyl- cydohexen. - (3:)- on-(5); 4.95 - Benzin, - Aceton, 2 - Äthylamylketon; 5-94 - Benzin, 6 - Cyclohexanon; 6.95 - Benzin, Acetessigsäureäthyl- ester. Dissolve 2o to 4o parts by weight of natural asphalt - in solvent mixtures, which consist of: - i. 95 percent by weight gasoline, 5 - acetone; 2.94 - petrol, 6 - acetophenone; 3.96 - petrol, 4 - i # i # 3-trimethyl cydohexen. - (3:) - on- (5); 4.95 - petrol, - acetone, 2 - ethyl amyl ketone; 5-94 - gasoline, 6 - cyclohexanone; 6.95 - gasoline, Ethyl acetoacetate ester.
