Description
Der Einsatz von Fasermaterialien zur Verstärkung anderer Werkstoffe wird aufgrund der damit erreichbaren einzigartigen Eigenschaften der resultierenden faserverstärkten Werkstoffe immer bedeutsamer.The use of fiber materials to reinforce others Because of the unique achievable Properties of the resulting fiber-reinforced materials more and more important.
Bekannte Beispiele für faserverstärkte Werkstoffe sind etwa Glas- oder Carbonfasern in Polyester (GFK, CFK), Asbestfasern in Beton ("Heraklit"), Stahlfasern in Beton (Stahlfaserbeton) sowie von Cordfäden aus Rayon, Polyamid, Stahl oder Aramid in Gummi (Reifen, Antriebselemente, Transportbänder, Schläuche usw.).Well-known examples of fiber-reinforced materials are, for example Glass or carbon fibers in polyester (GFK, CFK), asbestos fibers in concrete ("Heraclitus"), steel fibers in concrete (steel fiber concrete) and of cord threads made of rayon, polyamide, steel or aramid in Rubber (tires, drive elements, conveyor belts, hoses etc.).
Dabei können die jeweils zur Verstärkung verwendeten Faserma terialien sowohl gerichtet als auch ungerichtet zum Einsatz gelangen. Als Fasermaterialien werden sowohl solche auf orga nischer (Fasern aus natürlichen Rohstoffen und Kunstfasern) als auch auf anorganischer Basis (Mineral- und Metallfasern) eingesetzt. Je nach den Anforderungen handelt es sich bei den Verstärkungsfasern um Kurz- oder Langfasern, Fäden oder Cord materialien. Als umschließende Medien für die Fasermateria lien sind etwa Polyestergießharze, Beton, Gummi und viele andere Werkstoffe im Einsatz.The fibers used for reinforcement can be used materials both directional and non-directional reach. As fiber materials, both those on orga nischer (fibers from natural raw materials and synthetic fibers) as well as on an inorganic basis (mineral and metal fibers) used. Depending on the requirements, the Reinforcing fibers around short or long fibers, threads or cord materials. As enclosing media for the fiber material Lien include polyester casting resins, concrete, rubber and many other materials in use.
Es ist auch möglich, die Eigenschaften von Bitumen durch Zusatz von Fasermaterialien zu verbessern. Dabei wurde jedoch festgestellt, daß Nachteile bei der Verstärkung von Bitumen durch Fasermaterial darin bestehen, daß viele Fasermateria lien, insbesondere auf organischer oder Stahlbasis sehr schlecht an Bitumen haften. Die erfindungsgemäße Aufgabe war es daher, ein Verfahren zu entwickeln, durch welches diese Nachteile mindestens teilweise beseitigt werden.It is also possible to change the properties of bitumen To improve the addition of fiber materials. However, it was found that disadvantages in the reinforcement of bitumen due to fiber material that many fiber materials lien, especially on an organic or steel basis adhere poorly to bitumen. The task according to the invention was it is therefore to develop a process by which this Disadvantages are at least partially eliminated.
Die erfindungsgemäße Aufgabe wird durch ein Verfahren zur Herstellung von faserverstärktem Bitumen gelöst, wobei man Verstärkungsfasern auf anorganischer oder/und organischer Basis verwendet, die mit einer Schicht von aufvulkanisiertem Gummi überzogen sind, und diese in das Bitumen einarbeitet.The object of the invention is achieved by a method for Production of fiber-reinforced bitumen solved, where one Reinforcing fibers on inorganic and / or organic Base used with a layer of vulcanized Are covered with rubber and incorporated into the bitumen.
Als Bitumen im Sinne der vorliegenden Erfindung versteht man vor allem natürlich vorkommende oder durch Destillation aus Naturstoffen hergestellt flüssige oder feste, schmelzbare oder lösliche Kohlenwasserstoffgemische, in denen auch Sauer stoffverbindungen mehr oder weniger enthalten sein können. Unter den Begriff Bitumen fallen auch verwandte Stoffe, wie Teer und Pech, die durch zersetzende Destillation aus organi schen Naturstoffen gewonnen werden, wobei die Peche den De stillationsrückstand darstellen. Weiterhin betrifft die vorliegende Erfindung auch Bitumenarten, die Polymerzusätze enthalten.Bitumen in the sense of the present invention means especially occurring naturally or by distillation Natural products made liquid or solid, meltable or soluble hydrocarbon mixtures in which acid Compounds can be contained more or less. The term bitumen also includes related substances such as Tar and pitch, which are produced by decomposing organic distillation natural substances are obtained, the pitches den De represent the breastfeeding residue. Furthermore, the present invention also bitumen types, the polymer additives contain.
Zu den Verstärkungsfasern auf organischer Basis, die bei dem erfindungsgemäßen Verfahren verwendet werden können, zählen etwa Fasern aus natürlichen Rohstoffen, wie Cellulose oder modifizierte Cellulose (z. B. Rayon), Kunstfasern aus Polyme risaten (z. B. Polyacrylnitril, Polyvinylchlorid, Polyvinyli denchlorid, fluorhaltige Polyvinylverbindungen, Polyethylen, Polypropylen, Polystyrol), aus Polykondensaten (z. B. Poly amid, Polyester, Polycarbonat, Polyimid, Polytriazol) aus Polyadditionsprodukten (z. B. Polyurethanelastomere), Carbon fasern oder Gemische davon. Besonders bevorzugt sind Fasern oder Cordmaterial aus Rayon, Polyester oder/und Polyamid. Unter den Polyamidfasern sind Aramide, d. h. Fasern aus voll aromatischen Polyamiden bevorzugt.To the organic-based reinforcing fibers used in the methods according to the invention can be used such as fibers made from natural raw materials such as cellulose or modified cellulose (e.g. rayon), synthetic fibers made of polyme risks (e.g. polyacrylonitrile, polyvinyl chloride, polyvinyli denchloride, fluorine-containing polyvinyl compounds, polyethylene, Polypropylene, polystyrene), from polycondensates (e.g. poly amide, polyester, polycarbonate, polyimide, polytriazole) Polyaddition products (e.g. polyurethane elastomers), carbon fibers or mixtures thereof. Fibers are particularly preferred or cord material made of rayon, polyester and / or polyamide. Among the polyamide fibers are aramids, i.e. H. Fibers from full aromatic polyamides preferred.
Zu den Verstärkungsfasern auf anorganischer Basis, die bei dem erfindungsgemäßen Verfahren verwendet werden können, zählen etwa Mineralfasern wie z. B. Glasfasern oder Asbest, metallische Fasern wie z. B. Stahlfasern oder Gemische davon. Unter den anorganischen Verstärkungsfasern sind dabei Fasern oder Cordmaterial aus Stahl besonders bevorzugt. To the inorganic-based reinforcing fibers used in can be used in the method according to the invention, include mineral fibers such as B. glass fibers or asbestos, metallic fibers such as B. steel fibers or mixtures thereof. Fibers are among the inorganic reinforcing fibers or cord material made of steel is particularly preferred.
Bei dem erfindungsgemäßen Verfahren können die Verstärkungs fasern gerichtet oder ungerichtet zum Einsatz kommen. Bei den Verstärkungsfasern kann es sich um Kurz- oder Langfasern, Fäden oder Cordmaterialien handeln, wobei Cordmaterialien bevorzugt sind.In the method according to the invention, the reinforcements fibers directional or non-directional. Both Reinforcing fibers can be short or long fibers, Threads or cord materials act, cord materials are preferred.
Bei dem erfindungsgemäßen Verfahren arbeitet man Verstär kungsfasern in das Bitumen ein, die mit einer haftfesten Schicht von aufvulkanisiertem Gummi überzogen sind. Die Be schichtung der Fasern mit Gummi kann dabei auf übliche Weise erfolgen. So kann z. B. bei organischen Fasern eine verbesser te Haftung von Gummi an die Faser durch eine Imprägnierung erreicht werden. Das Imprägnieren der Verstärkungsfasern kann durch Haftvermittler auf Isocyanat- oder/und Vinylpyridin/Re sorcin/Formaldehyd-Basis bewirkt werden. Haftvermittler auf Isocyanatbasis werden meist der Lösung einer Gummimischung zugesetzt, die dann auf die zu imprägnierenden Fasern aufge tragen wird. Zur Verbesserung der Haftung können der Mischung auch Resorcin und Formaldehyd (z. B. in Form von Hexamethylen tetramin) oder auch Resorcin/Formaldehyd-Vorkondensate zugesetzt werden. Es kann jedoch auch eine Präparierung der Faser- bzw. Textilmaterialien mit Vinylpyridinlatex-Resor cin/Formadehydekombinationen z. B. durch Eintauchen der Fasern in eine Haftlösung erreicht werden.In the method according to the invention, amplifiers are used fibers into the bitumen with a strong adhesive Layer of vulcanized rubber are covered. The Be Layering the fibers with rubber can be done in the usual way respectively. So z. B. an improvement in organic fibers te adhesion of rubber to the fiber by impregnation can be achieved. The impregnation of the reinforcing fibers can through adhesion promoters on isocyanate and / or vinyl pyridine / Re sorcinol / formaldehyde base. Adhesion promoter on Isocyanate base are usually the solution of a rubber mixture added, which then applied to the fibers to be impregnated will wear. The mixture can be used to improve the adhesion also resorcinol and formaldehyde (e.g. in the form of hexamethylene tetramine) or resorcinol / formaldehyde precondensates be added. However, it can also be a preparation of the Fiber or textile materials with vinyl pyridine latex resor cin / formadehyde combinations e.g. B. by immersing the fibers can be achieved in an adhesive solution.
Auch die Gummibeschichtung von Stahlfasern kann durch Behand lung der Fasern mit einem Haftvermittler erreicht werden. Als Haftvermittler zwischen Metall und einer Gummimischung sind etwa eine metallische Zwischenschicht, insbesondere aus Mes sing oder Zink, Hartgummi, Isocyanate, Chlorkautschuk, Phe nolharz-Haftmittel oder/und Siloxane geeignet. Beispielsweise kann man Stahlfasern mit Gummi beschichten, indem man sie zunächst mit einer Auflage von Zink oder Messing versieht und anschließend Gummimischungen, welche bekannte Haftmittel wie z. B. Cobaltseifen in Verbindung mit höheren Schwefelkonzen trationen oder Resorcin und Formaldehyd (z. B. in Form von Hexamethylentetramin) oder Resorcin/Formaldehyd-Vorkondensate enthalten, auf die mit dem Haftvermittler beschichtete Faser aufvulkanisiert.The rubber coating of steel fibers can also be treated tion of the fibers can be achieved with an adhesion promoter. As There are adhesion promoters between metal and a rubber mixture such as a metallic intermediate layer, in particular made of mes sing or zinc, hard rubber, isocyanates, chlorinated rubber, Phe Resin adhesive or / and siloxanes suitable. For example you can coat steel fibers with rubber by first provided with a coating of zinc or brass and then rubber mixtures, which known adhesives such as e.g. B. cobalt soaps in conjunction with higher sulfur concentrations trations or resorcinol and formaldehyde (e.g. in the form of Hexamethylenetetramine) or resorcinol / formaldehyde precondensates included on the fiber coated with the coupling agent vulcanized.
Die auf diese Weise mit Gummi beschichteten Textilmaterialien werden in den Bitumen vorzugsweise in zerkleinerter Form eingebracht.The textile materials coated with rubber in this way are preferably crushed in the bitumen brought in.
In einer besonders bevorzugten Ausführungsform des erfin dungsgemäßen Verfahrens verwendet man als Verstärkungsfasern Cordmaterialien, die aus Altgummimaterialien, insbesondere Altreifen gewonnen werden.In a particularly preferred embodiment of the invent The method according to the invention is used as reinforcing fibers Cord materials made from waste rubber materials, in particular Old tires can be obtained.
Die Gewinnung von Fasern aus Altreifen kann z. B. dadurch geschehen, daß die Altmaterialien unter Verwendung der in der DE-PS 29 11 251 beschriebenen Zerkleinerungsmaschine in Stük ke zerschnitten werden. Dabei wird der Reifenkörper in einem ersten Schneidvorgang tangential zum Wulst eingeschnitten und in Umfangsstreifen unterteilt. Zumindest die Umfangsstreifen der Lauffläche können dann in einem zweiten Schneidvorgang quer durchgeschnitten werden. Die so zerkleinerten Stücke können anschließend in einem Schredder noch weiter zerklei nert werden. Anschließend können die in den zerkleinerten Reifenstücken enthaltenen metallischen Faserbestandteile mittels eines Magnetfelds und die Faserbestandteile auf or ganischer Basis mittels Windsichtung isoliert werden.The extraction of fibers from used tires can e.g. B. thereby happen that the waste materials using the in the DE-PS 29 11 251 described shredding machine in Stük ke be cut. The tire body is in one first cut tangentially to the bead and divided into circumferential strips. At least the perimeter stripes the tread can then be cut in a second be cut across. The pieces so crushed can then be shredded even further in a shredder be noted. Then the shredded Tire pieces contained metallic fiber components by means of a magnetic field and the fiber components on or ganic base can be isolated by wind sifting.
Für das erfindungsgemäße Verfahren ist es möglich, Fasern zu verwenden, die direkt vor der Verwendung, d. h. der Einarbei tung in das Bitumen mit Gummi beschichtet wurden. Es ist aber ebenso möglich, aus Altmaterial gewonnene Fasern zu verwen den, die bereits vor längerer Zeit, z. B. bei der Reifenher stellung mit Gummi beschichtet wurden. Die Verwendung von bereits mit Gummi beschichteten Fasern, insbesondere aus Rayon, Stahl, Polyester oder/und Polyamid aus Altreifen oder anderen faserhaltigen Gummiartikeln durch Zerkleinerung ist für das erfindungsgemäße Verfahren zur Faserverstärkung von Bitumen bevorzugt. For the process according to the invention it is possible to add fibers use immediately before use, d. H. the familiarization into which bitumen was coated with rubber. But it is it is also possible to use fibers obtained from old material those who have been around for a long time, e.g. B. at the Reifenher position were coated with rubber. The use of fibers already coated with rubber, in particular from Rayon, steel, polyester and / or polyamide from old tires or other fibrous rubber articles by crushing for the inventive method for fiber reinforcement of Bitumen preferred.
Bei dem erfindungsgemäßen Verfahren hat es sich als günstig erwiesen, wenn man Verstärkungsfasern in einer Menge von 1 bis 70 Gew.-% bezogen auf das Gesamtgewicht des faserver stärkten Bitumens in das Bitumen einarbeitet. Vorzugsweise arbeitet man eine Menge von 5 bis 50 Gew.-%, besonders bevor zugt 10 bis 40 Gew.-% Verstärkungsfasern bezogen auf das Gesamtgewicht des faserverstärkten Bitumens ein. Für spe zielle Anwendungsformen ist es jedoch möglich, daß die Menge der eingearbeiteten Verstärkungsfasern auch außerhalb der genannten Bereiche liegt.In the method according to the invention, it has proven to be advantageous proven when reinforcing fibers in an amount of 1 up to 70 wt .-% based on the total weight of the fiber strengthened bitumen into the bitumen. Preferably you work an amount of 5 to 50 wt .-%, especially before adds 10 to 40 wt .-% reinforcing fibers based on the Total weight of the fiber-reinforced bitumen. For spe However, it is possible that the quantity of the incorporated reinforcing fibers outside of the mentioned areas.
