Description
Verfahren zur Herstellung von Dichtungs- und Isolationsbelägen auf der Basis von Bitumenemulsionen.Process for the production of sealing and insulation coverings the basis of bitumen emulsions.
Bitumenemulsionen werden auf der Straße zur Herstellung bituminöser Beläge eingesetzt.Bitumen emulsions are becoming more bituminous on the road to manufacture Coverings used.
Weiterhin kennt man eine Reihe von Bitumenemulsionen, die im Streich- oder Spritzverfahren zur Bautenisolierung Verwendung finden Beim Einsatz aller dieser Materialien spielt der Brechvorgang für die Qualität des entstehenden Belages eine entscheidende Rolle, denn häufig werden diese Beläge in noch nicht vollstandig abgebundenem Zustand Beanspruchungen ausgesetzt, die deren Qualität erheblich mindern.There are also a number of bitumen emulsions that are or spray processes for building insulation are used when using all of these The crushing process plays a role in the quality of the resulting covering crucial role, because these coverings are often not completely set Condition exposed to stresses that significantly reduce their quality.
Es ist ferner ein Verfahren bekannt, bei dem Bitumenemulsionen mit einem Fällmittel verspritzt werden, wobei die oben skizzierten Nachteile nicht auftreten. Als Fällmittel werden in der Regel relativ konzentrierte elektrolythaltige wäßrige Lösungen eingesetzt (deutsche Auslegeschrift 1 204 980).It is also known a method in which bitumen emulsions with a precipitant are sprayed, whereby the disadvantages outlined above do not occur. As a rule, relatively concentrated aqueous electrolytes are used as precipitants Solutions used (German Auslegeschrift 1 204 980).
Die Aufgabe der vorliegenden Erfindung ist darauf gerichtet, ein Verfahren zur Herstellung von Dichtungsw und Isolationsbelägen auf der Basis von Bitumenemulsionen zu entwickeln, das geeignet ist, sowohl feuchte als auch in ihrem Aufbau variierende Gesteinsfläehela mit einer ausreichend haftenden Belagschicht zu versehen, wobei die Fällung des bituminösen Bindemittels durch gleichartige Stoffe bewirkt werden soll.The object of the present invention is directed to a method for the production of sealing and insulation coverings on the base of bitumen emulsions suitable for both wet and in The structure of the rock surface varies with a sufficiently adherent layer of pavement to provide, whereby the precipitation of the bituminous binder by similar substances should be effected.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren gelöst, das dadurch gekennzeichnet ist, daß man eine kationische und eine anionische Emulsion, die beim Vermischen sofort brechen, gleichzeitig versprüht. Sie beruht also darauf, gleichzeitig zwei unverträgliche Emulsionen zu versprühen, wobei - bedingt durch den intensiven Mischvorgang - augenblicklich das Bindemittel ausgeschieden und ein zusammenhängender Dichtungsbelag gebildet wird. Diese kationischen und anionischen Bitumenemulsionen sind naturgemäß nicht nur auf das Bitumen beschränkt, es können vielmehr auch modifizierte Bitumina - z. B. mit Teeröl, Kunststoff-Latices, Mineralölen u.ä.The object is achieved according to the invention by a method that thereby is characterized in that you have a cationic and an anionic emulsion, which when Break mixing immediately, spraying at the same time. So it is based on it, at the same time To spray two incompatible emulsions, whereby - due to the intense Mixing process - instantly the binder excreted and a cohesive one Sealing lining is formed. These cationic and anionic bitumen emulsions are of course not limited to the bitumen, modified ones can also be used Bitumina - e.g. B. with tar oil, plastic latices, mineral oils and the like.
verschnitten - eingesetzt werden. Um die rheologischen Eigenschaften des entstehenden Belages, insbesondere bei Tlannelabdichtungen oder bei Abdichtungen an anderen senkrechten Flächen günstig zu beeinflussen, kann gleichzeitig mit den beiden Emulsionen ein Armierungsmaterial versprüht werden.blended - to be used. About the rheological properties of the resulting covering, especially in the case of tlannel seals or seals on other vertical surfaces can be beneficial at the same time as the A reinforcing material can be sprayed onto both emulsions.
Als Armierungsmaterial kommen Glasfaser, synthetische Faser, Asbest und dergleichen in Betracht.Glass fiber, synthetic fiber and asbestos are used as reinforcement materials and the like into consideration.
Die so gewonnenen Isolierschichten können in einem Arbeitsgang beliebig dick aufgetragen werden. Durch den Einsatz sowohl katinnischer als auch anionischer Emulsionen enthält das Bindemittel Zusätze, um sowohl feuchte als auch in ihrem Aufbau variierende Gesteinsflächen mit einer ausreichend haftenden Belagschicht zu versehen.Any insulation layers obtained in this way can be used in one operation be applied thickly. By using both catinnic and anionic The binder contains additives to keep both moist and in their emulsions Structure of varying rock surfaces with a sufficiently adherent layer of pavement to provide.
Zur Erläuterung sei hier angeführt, daß vielfach sowohl den bituminösen Heiß- als auch den Kalt-Massen sogenannte Haftmittel zugesetzt werden, die in ihrer chemischen Konstitution z. T. mit den hier eingesetzten Emulgatoren identisch sind.For explanation it should be mentioned here that in many cases both the bituminous Hot and cold masses so-called adhesives added be that in their chemical constitution z. T. with the emulsifiers used here are identical.
In Frage kommen z. B. Fettsäureamine, Iminoamine und Bettsäureamide. Weiterhin können dem Bindemittel mit Vorteil sogenannte Wurzelgifte zugesetzt werden, um freiliegende Dichtungs- bzw. Isolierflächen vor einem lhlchsbefall zu schützen.Possible are e.g. B. fatty acid amines, iminoamines and bed acid amides. Furthermore, so-called root poisons can advantageously be added to the binding agent, in order to protect exposed sealing or insulating surfaces from being attacked by bulls.
Die Isolierungen können auch in Kombination mit den üblichen Trägermaterialien wie Glasseidengewebe, Jutegewebe usw. eingesetzt werden.The insulation can also be used in combination with the usual carrier materials such as glass silk fabric, jute fabric, etc. are used.
Bei der Verarbeitung des Bitumens gemäß der Erfindung werden die ursprünglichen Eigenschaften des Bindemittels erhalten, da es keinen höheren Temperaturen ausgesetzt wird und somit die gefürchteten Crack-Erscheinungen unterbleiben. Da bei normaler Temperatur gearbeitet wird, besteht insbesondere in geschlossenen oder schlecht gelüfteten Räumen nicht die Gefahr der Gesundheitsschädigung der Arbeiter, da sie keinen giftigen Dämpfen ausgesetzt sind. Diese Vorteile sind insbesondere bei Isolierarbeiten in Bergwerken und Tunneln wichtig.When processing the bitumen according to the invention, the original Properties of the binder are preserved as it is not exposed to higher temperatures and thus the dreaded crack phenomena do not occur. Since with normal Temperature is worked, in particular in closed or poor Ventilated rooms do not pose a risk of harm to the health of workers as they are not exposed to toxic fumes. These advantages are particularly useful when doing insulation work important in mines and tunnels.
Beispiel 1: Nachstehend werden eine kationische Emulsion, die ein Wurzelgift enthält, sowie eine anionische Emulsion mit einem Latex-Zusatz angeführt. Die Herstellungen der Emulsionen erfolgen in an sich bekannter Weise, indem der Emulgator in der bituminösen Phase gelöst wird, während die wasserlöslichen Bestandteile in der wäßrigen Phase enthalten sind. Mit Hilfe geeigneter Dispergiergeräte, wie z. B. Kolloid-Mühlen, wird für eine feine Verteilung gesorgt. Die beiden Emulsionen werden gleichzeitig auf eine Gesteinsfläche gesprüht.Example 1: The following is a cationic emulsion that contains a Contains root poison, as well as an anionic emulsion with a latex additive. The emulsions are prepared in a manner known per se by the Emulsifier is dissolved in the bituminous phase, while the water-soluble components are contained in the aqueous phase. With the help of suitable dispersing equipment, such as z. B. colloid mills ensure a fine distribution. The two emulsions are sprayed onto a rock surface at the same time.
