Description
DEUTSCHESGERMAN
Die Erfindung betrifft Asphalt- und Teeremulsionen, insbesondere für Straßenbauzwecke. The invention relates to asphalt and tar emulsions, particularly for road construction purposes.
Für den Straßenbau und ähnliche Zwecke verwendet man Emulsionen aus Asphalt und Teeren, die als Dispergierungsmittel vorwiegend Fettsäuren, Sulfosäuren und ähnliche Stoffe enthalten. Ferner hat man organische und anorganische Stabilisatoren hinzugefügt.Asphalt and emulsions are used for road construction and similar purposes Tars, which are used as dispersants, mainly fatty acids, sulfonic acids and the like Contain substances. Organic and inorganic stabilizers have also been added.
Es ist auch bekannt, daß tierische Phosphatide gute Emulgierungsmittel sind und daß Eidotter, Hirnsubstanz o. dgl. zur Herstellung von Emulsionen geeignet sind.It is also known that animal phosphatides are good emulsifying agents and that egg yolks, brain matter or the like are suitable for the production of emulsions.
Diese bekannten Phosphatide tierischer Art können natürlich praktisch für technische Zwecke, insbesondere für die Herstellung von Asphalt- und Teeremulsionen für Straßenbauzwecke, nicht verwendet werden.These well-known animal phosphatides can of course come in handy for technical ones Purposes, in particular for the production of asphalt and tar emulsions for road construction purposes, Not used.
Es wurde nun die überraschende Beobachtung gemacht, daß Phosphatide und insbesondere die bis dahin unverwertbaren Abbauprodukte derselben aus pflanzlichen Rohstoffen, beispielsweise aus Sojabohnen, gute und wohlfeile Emulgierungsmittel für Asp halt- und Teeremulsionen für den Straßenbau sind. Sehr gut geeignet sind für diesen Zweck die aus Sojabohnen gewonnenen, in erheblichen Mengen zur Verfügung stehenden Phosphatide, die aus dem Sojabohnenöl nach dessen Extraktion mit geeigneten Lösungsmitteln ausgeschieden werden und stets fettes Öl in Mengen von etwa 30 bis 50 o/0 ,enthalten, das sich auf mechanischem Wege von dem Lecithin nicht trennen läßt.The surprising observation has now been made that phosphatides and in particular the previously unusable degradation products of the same from vegetable raw materials, for example from soybeans, are good and inexpensive emulsifiers for asphalt and tar emulsions for road construction. Very suitable for this purpose are the soybean-derived property in substantial quantities available phosphatides, which are excreted from the soybean oil according to the extraction with suitable solvents and always fixed oil in amounts of about 30 to 50 o / 0 contained, the cannot be separated from the lecithin by mechanical means.
Es gelingt nun, durch Zusatz des Phosphatide und fettes Öl enthaltenden Abfallstoffes, evtl. unter Zugabe geringer Alkalimengen, um die vorhandenen freien Fettsäuren abzusättigen, Emulsionen aus Teeren und Asphalten zu. erhalten.By adding the waste material containing phosphatides and fatty oil, possibly with the addition of small amounts of alkali in order to saturate the free fatty acids present, emulsions of tar and asphalt can now be achieved. obtain.
Diese Emulsionen zeichnen sich dadurch aus, daß sie gegen Temperaturwechsel sehr beständig sind, gut brechen und einen guten Überzug über das Straßenbaumaterial bei jeder Art der Verwendung ermöglichen, bevor das Brechen, d. h. die Wasserabscheidung, eintritt.These emulsions are characterized by the fact that they are very resistant to temperature changes are resistant, break well and provide a good coating over the pavement material allow any kind of use before breaking, d. H. the water separation, entry.
Die Herstellung der Emulsionen geschieht im übrigen in der bekannten Weise. Es genügen zur Herstellung der Emulsionen kleine Mengen Phosphatide, insbesondere ölhaltige Phosphatide. Ebenso können die erheblichen Mengen phosphorhaltige Abbau- und Zersetzungsprodukte enthaltenden Stoffe für diesen Zweck benutzt werden, die bei der Reinigung des Lecithins abfallen, das für Nahrungsmittelzwecke und ähnliche Anwendungsgebiete bestimmt ist.The emulsions are otherwise produced in the known manner. It Small amounts of phosphatides, in particular oil-containing phosphatides, are sufficient to produce the emulsions. Likewise, the substantial Quantities of substances containing phosphorus-containing decomposition and decomposition products are used for this purpose the cleaning of the lecithin, which is used for food and similar applications is determined.
