Description

Kunstsstoffprofil ·...*..* *..·...* ..* : Plastic profile ·...*..* *..·...* ..* :

Die Erfindung betrifft ein Kunststoffprofil, das im Extrusions- oder !ntrusionsverfahren aus wenigstens zwei in der Farbe und/oder Härte unterschiedlichen Komponenten hergestellt ist und zur Gewährleistung der Formstabiiität mit einer Armierung aus metallischem Werkstoff ausgerüstet ist.The invention relates to a plastic profile which is produced by extrusion or intrusion from at least two components differing in color and/or hardness and is equipped with a reinforcement made of metallic material to ensure dimensional stability.

Es ist üblich, in extrudierten Kunststoffprofiien, auch solchen aus mehreren Komponenten, zur Gewährleistung von deren Formstabilität, insbesondere bei Temperaturveränderungen, Armierungen zu positionieren, diese in dem Kunststoff einzubetten. Als Werkstoff für die Armierung bieten sich Metalle an. Metalle sind aufgrund ihres niedrigeren Wärmeausdehnungskoefizienten und der höheren Festigkeit, gegenüber Kunststoffen, geeignet, die Formstabilität von Kunststoffprofilen zu erhöhen. Es ist besonders vorteilhaft, die Armierung allseitig vom Kunststoff umgeben in dem Profil zu positionieren. It is common practice to position reinforcements in extruded plastic profiles, including those made from multiple components, to ensure their dimensional stability, especially when temperatures change, and to embed them in the plastic. Metals are a good material for the reinforcement. Metals are suitable for increasing the dimensional stability of plastic profiles due to their lower coefficient of thermal expansion and higher strength compared to plastics. It is particularly advantageous to position the reinforcement in the profile surrounded by the plastic on all sides.

Die Armierung ist meist ein strangähnliches Gebilde, das im Extrusionswerkzeug von dem in der thermoplastischen Phase, in hochviskoser Form befindlichem Kunststoff umhüllt wird und mit diesem eine form- und kraftschlüssige Verbindung eingeht.The reinforcement is usually a strand-like structure that is covered in the extrusion tool by the plastic in the thermoplastic phase, in a highly viscous form, and forms a positive and non-positive connection with it.

Um zu gewährleisten, daß die Armierung mit dem Kunststoff eine möglichst mechanisch feste Verbindung eingeht, ist es Stand der Technik, an strangförmigen Armierungen Aussparungen, zur Herstellung eines Formschiusses mit dem Kunststoff, vorzusehen. Zur Herstellung einer kraftschlüssigen Haftung zwischen Kunststoff und metallischer Armierung sind eine Primerung oder eine Wärmebehandlung der metallischen Oberfläche dafür übliche Maßnahmen.In order to ensure that the reinforcement forms the most mechanically strong connection possible with the plastic, it is state of the art to provide recesses in strand-shaped reinforcements to create a form-fit connection with the plastic. To create a force-fit bond between the plastic and the metal reinforcement, priming or heat treatment of the metal surface are common measures.

All diesen Maßnahmen ist eigen, daß die Aufwendungen, um einen zufriedenstellenden Effekt, nämlich ein in sich formstabiles, aus wenigstens zwei Komponenten bestehendes Kunststoffprofil zu erzielen, unverhältnismäßig hoch sind.What is common to all these measures is that the costs required to achieve a satisfactory effect, namely a dimensionally stable plastic profile consisting of at least two components, are disproportionately high.

Auch in qualitativer Hinsicht sind diese Maßnahmen nur bedingt von zufriedenstellendem Ergebnis. So kommt es bei geprimerten oder wärmevorbehandelten metallischen Armierungen nicht selten zur Ablagerung von Abrieb im Extrusionswerkzeug und in deren Folge zu mangelbehafteten Kunststoffprofiien. In terms of quality, these measures only produce satisfactory results to a limited extent. For example, with primed or heat-pretreated metallic reinforcements, it is not uncommon for abrasion debris to build up in the extrusion tool, resulting in defective plastic profiles.

Aufgabe der Erfindung ist es, das zugrundegelegte gattungsgemäße Kunststoffprofi! dahingehend zu verbessern, daß es, bei einem quantitativ geringeren Einsatz von metallischem Armierungsmaterial und geringeren Aufwendungen für dessen Haftvermittlung gegenüber dem Kunststoff, in sich formstabii ist, insbesondere unter der Einwirkung von Temperaturveränderungen, Längenausdehnungen besser kompensiert und gerade bleibt.The object of the invention is to improve the generic plastic profile used in such a way that, with a quantitatively lower use of metallic reinforcing material and lower expenditure for its adhesion compared to the plastic, it is inherently dimensionally stable, particularly under the influence of temperature changes, better compensates for linear expansions and remains straight.

Diese Aufgabe wird bei einem Kunststoffprofi! nach dem Oberbegriff des Schutzanspruchs 1 erfindungsgemäß durch die Merkmale im kennzeichnenden Teil gelöst.This task is solved according to the invention in a plastic professional! according to the preamble of claim 1 by the features in the characterizing part.

Die erfindungsgemäßen Maßnahmen gewährleisten die Bereitstellung eines Kunststoffprofiles, das ausThe measures according to the invention ensure the provision of a plastic profile which consists of

wenigstens zwei Komponenten besteht und das mitteis einer metallischen Armierung, die form- und kraftschlüssig in dem Kunststoff eingebettet ist, in sich, gegenüber zu Verwerfungen führenden Temperaturveränderungen, formstabil ist. Die Formstabilität ist vor allem hinsichtlich einer Längenausdehnung des Kunststoffprofiles bei einem Verbund mit einem metallischen Träger oder Rahmen ein wesentliches Qualitätskriterium, ebenso die Kompensierung von Spannungen und Verwerfungen, die nicht selten zu Ablösungen führen.consists of at least two components and is inherently dimensionally stable against temperature changes that lead to distortions by means of a metallic reinforcement that is embedded in the plastic in a form-fitting and force-fitting manner. Dimensional stability is an important quality criterion, particularly with regard to the linear expansion of the plastic profile when combined with a metallic support or frame, as is the compensation of tensions and distortions that often lead to detachment.

Auch die Geradheit des erfindungsgemäßen Kunststoffprofiles, nicht selten beschreiben stranggepreßte Kunststoffprofile eine Kurve, sind nicht gerade, ist das Ergebnis der erfindungsgemäßen Ausbildung und Anordnung der metallischen Armierung.The straightness of the plastic profile according to the invention - extruded plastic profiles often describe a curve and are not straight - is also the result of the inventive design and arrangement of the metallic reinforcement.

Die Haftvermittlung zwischen Armierung und Kunststoff kann zusätzlich noch dadurch verbessert werden, indem die Armierung als Widerstandsschweißdraht kurzzeitig benutzt wird.The bond between the reinforcement and the plastic can be further improved by using the reinforcement as a resistance welding wire for a short time.

Die Erfindung wird anhand von Zeichnungen näher erläutert. Es zeigen:The invention is explained in more detail with reference to drawings. They show:
