Description
Die Erfindung bezieht sich auf Dübel bzw. Befetigungsmaterialien aus Kunststoff zur Herstellung von Befestigungen in einem Bohrloch.The invention relates to plastic anchoring or fastening materials for the production of fasteners in a borehole.
Zur Herstellung von Dübeln bzw. von Befestigungsmaterialien in einem Bohrloch ist es bereits bekannt, Kunststoffmaterial mit eingebetteten Füllstoffen zu verwenden.For the production of dowels or fastening materials in a borehole, it is already known to use plastic material with embedded fillers.

Der Erfindung liegt die Aufgabe zugrunde, Dübel bzw. Befestigungsmaterialien der eingangs genannten Art zu schaffen, deren Eigenschaften in einfacher und präzise reproduzierbarer Weise an gewünschte Bedingungen angepasst werden können.The invention has for its object to provide dowels or mounting materials of the type mentioned, the properties of which can be adapted to desired conditions in a simple and precisely reproducible manner.
Diese Aufgabe wird durch die im Patentanspruch 1 bzw. 15 gelöst.This object is achieved by the in
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.
Durch die erfindungsgemäße Ausgestaltung des Dübels bzw. des Befestigungsmaterials wird eine weitgehend dauerhafte Erhöhung der Festigkeitseigenschaften und Haltekräfte von im Spritzgussverfahren hergestellten Dübeln bei gleichzeitiger Senkung des Gewichts durch den Einsatz der Hohlkugeln erreicht.Due to the inventive design of the anchor or the fastening material is a largely permanent increase in the strength properties and holding forces of dowels produced by injection molding while reducing the weight achieved by the use of hollow spheres.
Die Hohlkugeln können sowohl den Granulaten beim Herstellen der Dübel zugesetzt werden oder sie können den in den schmelzflüssigen Zustand gebrachten Kunststoffmaterialien zugesetzt werden. Das Befestigungsmaterial kann mehrere Komponenten enthalten, die zur Aushärtung des Kunststoffmaterials miteinander vemischt werden, wobei zumindest eine der Komponenten die Hohlkugeln enthält.The hollow spheres can either be added to the granules during the preparation of the dowels or they can be added to the plastic materials brought into the molten state. The attachment material may include a plurality of components that are mixed together to cure the plastic material, wherein at least one of the components contains the hollow spheres.
Im Gegensatz zu anderen Füllstoffen ergeben die Hohlkugeln eine bessere Formstabilität aufgrund des geringeren Schwunds bei der Aushärtung des Kunststoffmaterials, und die so hergestellten Dübel oder Befestigungsmaterialien weisen eine geringere Wärmeleitfähigkeit und höherer Festigkeitseigenschaften auf.In contrast to other fillers, the hollow spheres provide better dimensional stability due to less shrinkage in the curing of the plastic material, and the dowels or mounting materials thus produced have lower thermal conductivity and higher strength properties.
Weiterhin ergeben die Hohlkugeln eine Senkung des Gewichts der daraus hergestellten Teile und eine Verringerung der Materialmenge des Kunststoffs, die zur Herstellung der Dübel bzw. des Befestigungsmaterials erforderlich ist.Furthermore, the hollow spheres give a reduction in the weight of the parts produced therefrom and a reduction in the amount of material of the plastic, which is required for the preparation of the dowels or the mounting material.
Die Hohlkugeln können aus Glas oder aus hochtemperaturbeständigen Kunststoffen oder aus Metall bestehen.The hollow spheres may be made of glass or of high temperature resistant plastics or of metal.
Zur Erhöhung der Haftung des Kunststoffes an den Hohlkugeln können die Hohlkugeln weiterhin mit einer Nano-Beschichtung versehen sein, oder die Oberfläche der Hohlkugeln kann für eine maximale Verbindung zwischen den Hohlkugeln und dem Kunststoffmaterial aufgeraut sein, wobei die Aufrauung so gering sein kann, dass eine Reduzierung der Druckfestigkeit der Hohlkugeln nicht auftritt.To increase the adhesion of the plastic to the hollow spheres, the hollow spheres can continue to be provided with a nano-coating, or the surface of the hollow spheres can be roughened for maximum connection between the hollow spheres and the plastic material, the roughening can be so low that a Reduction of the compressive strength of the hollow spheres does not occur.
Dem Kunststoffmaterial können weiterhin zusätzlich flächenförmige oder plättchenförmige Materialien, wie z. B. Glimmer, zur Behinderung der Verschieblichkeit der Hohlkugeln zugesetzt werden.The plastic material can continue to additionally sheet-like or platelet-shaped materials, such. B. mica, are added to hinder the mobility of the hollow spheres.
Die Hohlkugeln können in dem Kunststoffmaterial über die gesamte Masse des Kunststoffdübels oder Befestigungsmaterials im Wesentlichen gleichförmig verteilt sein, oder es kann durch gezielte Zuführung der Hohlkugeln zu dem Granulat bzw. dem aufgeschmolzenen Granulat eine unterschiedliche Verteilung über das Volumen und damit über die Erstreckung des Dübels oder Befestigungsmaterials erreicht werden.The hollow spheres can be substantially uniformly distributed in the plastic material over the entire mass of the plastic dowel or mounting material, or it can by targeted supply of the hollow spheres to the granules or the molten granules, a different distribution over the volume and thus over the extension of the dowel or Mounting material can be achieved.
Die Erfindung wird im Folgenden anhand von in der Zeichnung dargestellten Ausführungsformen noch näher erläutert.The invention will be explained in more detail below with reference to embodiments shown in the drawing.

Weiterhin ist es möglich, die Oberfläche der Hohlkugeln aufzurauen, um eine Haftung zwischen dem Kunststoff und der Hohlkugel zu vergrößern.Furthermore, it is possible to roughen the surface of the hollow spheres in order to increase adhesion between the plastic and the hollow sphere.
Diese Aufrauung kann beispielsweise durch mechanische oder chemische Prozesse erreicht werden.This roughening can be achieved, for example, by mechanical or chemical processes.
Weiterhin kann es vorteilhaft sein, zusätzlich zu den Hohlkugeln weitere Zusatzstoffe, wie z. B. plättchenförmige Materialien, dem Kunststoffmaterial zuzusetzen, um die Beweglichkeit der Hohlkugeln in dem noch flüssigen Kunststoffmaterial bei der Formung zu verringern.Furthermore, it may be advantageous, in addition to the hollow spheres further additives such. As platelet-like materials, the plastic material to increase the mobility of the hollow spheres in the still liquid plastic material in the molding.
Ein weiteres vorteilhaftes Verfahren besteht darin, Hohlkugeln aus einem Material mit Erinnerungsvermögen zu verwenden, das sich beim Spritzen infolge der Temperaturerhöhung in der Schmelze ausdehnt, so dass der Kunststoff beim Abkühlen Spannungen aufbaut, die festigkeitssteigernd wirken.Another advantageous method is to use hollow spheres of a memory material that expands during injection as a result of the temperature increase in the melt, so that the plastic builds up stresses during cooling, which act to increase strength.
Entgegen der naheliegenden Auffassung, dass durch die Hohlkugeln die Festigkeit, insbesondere die Druckfestigkeit des Kunststoffes des Dübels verringert wird, wurde festgestellt, dass sich durch die Einbettung der Hohlkugeln in das Kunststoffmaterial eine Erhöhung der Festigkeit ergibt, die gezielt in bestimmten Bereichen des Dübels oder über das gesamte Volumen des Dübels eingesetzt werden kann.Contrary to the obvious view that the strength, in particular the compressive strength of the plastic of the anchor is reduced by the hollow spheres, it has been found that the embedding of the hollow spheres in the plastic material results in an increase in strength, the targeted in certain areas of the dowel or over the entire volume of the anchor can be used.
