Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Kunststoff-Profilen mit Verstärkungseinlage gemäß dem Oberbegriff des Anspruchs 1. Sie betrifft ferner Kunststoff-Profile, die nach diesem Verfahren hergestellt sind und die Verwendung derartiger Profile.The The invention relates to a method for producing plastic profiles with reinforcing insert according to the preamble of claim 1. It also relates to plastic profiles, according to manufactured this method and the use of such Profiles.
Aus thermoplastischen Kunststoffen mittels Extrusion hergestellte Kunststoff-Profile haben viele Vorteile. Hierzu gehören beispielsweise die Möglichkeit, auch komplizierte Querschnitte zu realisieren, das geringe Gewicht und die hohe Beständigkeit gegen Umwelteinflüsse. Zu den Nachteilen zählen die hohe thermische Wärmedehnung und die im Vergleich zu Metallen geringe Festigkeit.Out thermoplastics produced by extrusion plastic profiles have many advantages. These include, for example, the Possibility to realize also complicated cross sections, the low weight and high resistance to environmental influences. The disadvantages include the high thermal expansion and the low strength compared to metals.
Dies hat die Fachwelt veranlasst, nach Möglichkeiten zu suchen, mit denen sich die Festigkeit der Kunststoff-Profile verbessern lässt.This has led the professional world to look for opportunities with which the strength of the plastic profiles improve leaves.

Bei dieser Koextrusion von Glasfasern und thermoplastischen Kunststoff stellen sich jedoch zwei grundsätzliche Schwierigkeiten ein. Die erste Schwierigkeit ergibt sich beim Anfahren der Extrusion; hier ist das extrudierte Profil über viele Meter unvollständig und muss verworfen werden. Dabei lässt sich das verworfene Material wegen der enthaltenen Glasfasern nicht mehr ohne Weiteres recyceln. Außerdem sind die teuren Glasfasern verloren. Die zweite Schwierigkeit ergibt sich aus der thermischen Ausdehnungsdifferenz zwischen Glasfaser und Kunststoff. Das Kunststoffmaterial verkürzt sich während des Abkühlens stark, während die Glasfasern ihre Länge im Wesentlichen beibehalten, so dass es zu Scherbewegungen zwischen Kunststoff und Glas kommt, die die Haftung zwischen den beiden Materialien stark beeinträchtigen. Das ist unbefriedigend.at this coextrusion of glass fibers and thermoplastic However, there are two fundamental difficulties one. The first difficulty arises when starting the extrusion; here the extruded profile is incomplete over many meters and must be discarded. This can be the rejected Material because of the contained glass fibers not more readily recycle. In addition, the expensive glass fibers are lost. The second difficulty arises from the thermal expansion difference between fiberglass and plastic. The plastic material shortens strong during cooling while the glass fibers essentially maintain their length, so that there is shear movement between plastic and glass, which greatly affect the adhesion between the two materials. That is unsatisfactory.
Ein weiterer Nachteil der mittels langen Verstärkungsfasern versteiften Kunststoff-Profile ist, dass es fast nicht möglich ist, die Profile nachträglich umzuformen. Beispielsweise besteht im Fenster- und Türenbereich oftmals der Wunsch, die Profile in eine runde Form zu biegen. Wegen der koextrudierten Verstärkungsfasern ist das jedoch nicht mehr möglich. Auch das ist unbefriedigend.One Another disadvantage of using long reinforcing fibers stiffened plastic profiles is that almost impossible is to reshape the profiles later. For example There is often a desire in window and door to bend the profiles into a round shape. Because of the coextruded reinforcing fibers But that is no longer possible. That too is unsatisfactory.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Herstellung von verstärkten Kunststoff-Profilen anzugeben, mit dem die vorstehend geschilderte Nachteile vermieden werden.Of the The present invention is therefore based on the object, a method to specify for the production of reinforced plastic profiles, with the above-described disadvantages are avoided.
Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1.These Task is solved by a method with the features of claim 1.
Das erfindungsgemäße Verfahren vereinigt mehrere Vorteile in sich. Zum ersten kann das Kunststoff-Profil ohne Schwierigkeiten und Besonderheiten extrudiert werden, da zu diesem Zeitpunkt noch keine Verstärkungsfasern verarbeitet werden müssen. Auch die beim Abkühlen eintretende Längenreduzierung verläuft völlig ungehindert. Des weiteren kann das abgekühlte Kunststoff-Profil verformt, beispielsweise zu einem Fensterbogen gebogen werden. Erst wenn das Kunststoff-Profil seine endgültige Form hat, wird das stabförmige Verstärkungselement in die jetzt noch offene Nut eingelegt und darin verankert.The inventive method combines several advantages in itself. First, the plastic profile without difficulty and peculiarities are extruded, since at that time still no reinforcing fibers have to be processed. Also the length reduction occurring on cooling runs completely unhindered. Furthermore, that can cooled plastic profile deformed, for example too to be bent in a window arch. Only when the plastic profile has its final shape becomes the rod-shaped Reinforcement inserted in the now still open groove and anchored in it.
Sollten beim Anfahren der Extrusion verformte Kunststoff-Profile anfallen, so können diese einfach abgeschnitten und recycelt werden. Teures Verstärkungsmaterial aus Glas- oder Kohlefaser ist zu diesem Zeitpunkt noch nicht verarbeitet.If deformed plastic profiles occur when starting the extrusion process, they can simply be cut off and recycled. Expensive Reinforcing material made of glass or carbon fiber is not processed at this time.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung besitzt die Nut ein hinterschnittenes Profil. Dies ermöglicht eine verbesserte Verankerung des Verstärkungselements.According to one advantageous embodiment of the invention, the groove has an undercut Profile. This allows for improved anchoring of the reinforcing element.
Vorteilhafterweise wird ein elastisches Verstärkungselement verwendet. Dies ermöglich die leichte Anpassung auch an gebogene oder anderweitig verformte Kunststoff-Profile.advantageously, an elastic reinforcing element is used. This allows the easy adaptation to curved or otherwise deformed plastic profiles.
Vorzugsweise wird als Verstärkungselement ein gebündelter Faserstrang aus Glas- oder Kohlefasern verwendet. Diese Materialien sind leicht, extrem fest und haben sich grundsätzlich als Verstärkung von thermoplastischen Kunststoffen bereits vielfach bewährt. Außerdem sind sie in praktisch unbegrenzter Länge erhältlich.Preferably is a bundled fiber strand as a reinforcing element made of glass or carbon fibers. These materials are light, extremely firm and have basically as reinforcement of Thermoplastic plastics already proven many times. In addition, they are in virtually unlimited length available.
Zur Verbesserung der Haftung des Verstärkungselements im Kunststoff-Profil wird gemäß einer Weiterbildung der Erfindung ein am Umfang profiliertes Verstärkungselement verwendet.to Improvement of the adhesion of the reinforcing element in the plastic profile is in accordance with a development of the invention a used on the circumference profiled reinforcing element.
Für die Verankerung des Verstärkungselements in der Nut des Kunststoff-Profils gibt es mehrere Möglichkeiten.For the anchoring of the reinforcing element in the groove of Plastic profiles there are several possibilities.
Eine erste Möglichkeit besteht darin, das Kunststoffmaterial im Bereich der Nut zu erwärmen und das Verstärkungselement in das erwärmte Kunststoffmaterial einzudrücken. Beim Abkühlen legt sich das Kunststoffmaterial fest um das Verstärkungselement.A The first possibility is the plastic material to heat in the area of the groove and the reinforcing element into the heated plastic material. Upon cooling, the plastic material lays down tightly the reinforcing element.
Eine zweite Möglichkeit besteht darin, das Verstärkungselement mit Hilfe eines Klebstoffs in der Nut festzukleben.A second possibility is the reinforcing element Stick with adhesive in the groove.
Eine dritte hier bevorzugte Möglichkeit sieht vor, zum Fixieren des Verstärkungselements die Nut mit einem gummiartigen Material mit hoher Haftreibung zum Verstärkungselement auszukleiden oder auszufüllen. Es hat sich überraschenderweise herausgestellt, dass insbesondere bei Verwendung eines am Umfang profilierten Verstärkungselements die Haftung zwischen Kunststoff-Profil und Verstärkungselement hervorragend ist.A third option preferred here, for fixing of the reinforcing element, the groove with a rubber-like Material with high static friction to the reinforcing element to be lined or completed. It has surprisingly that particular when using one on the perimeter profiled reinforcing element the adhesion between Plastic profile and reinforcing element excellent is.
Es versteht sich, dass in allen zuvor beschriebenen Möglichkeiten zur Befestigung des Verstärkungselements Materialien verwendet werden, die sowohl zum Kunststoff des Profils als auch zum Verstärkungselement kompatibel sind.It It goes without saying that in all the possibilities described above used for fastening the reinforcing element materials which are both the plastic of the profile and the reinforcing element are compatible.
Zum Erreichen einer ansprechenden Optik kann die gefüllte Nut abschließend mit einer Decklage aus Kunststoff oder dergleichen verschlossen werden.To the Achieving an attractive appearance, the filled groove finally with a cover layer of plastic or the like be closed.
Das Ausfüllen der Nut und das Aufbringen der Decklage wird vorzugsweise mit Hilfe der sogenannten Seitenextrusion durchgeführt. Dieses Verfahren lässt sich in den kontinuierlichen Fertigungsprozess optimal einbinden.The Filling the groove and the application of the cover layer is preferably carried out by means of the so-called side extrusion. This process can be used in the continuous manufacturing process integrate optimally.
Gegenstand der vorliegenden Erfindung sind auch Kunststoff-Profile, hergestellt nach dem erfindungsgemäßen Verfahren, wie sie in den Patentansprüchen 11 bis 15 definiert sind. Vorteilhaft an diesen Kunststoff-Profilen ist die einfache Herstellung, insbesondere die Möglichkeit, den zunächst unverstärkten Profilstab in jede gewünschte Endform bringen zu können, ohne dass dies durch das Verstärkungselement behindert wird. Nach Fertigstellung hat das Kunststoff-Profil jedoch in jedem Fall die gewünschte Festigkeit und Stabilität.object The present invention also plastic profiles are made according to the inventive method, as they are are defined in the claims 11 to 15. Advantageous At these plastic profiles is the ease of manufacture, in particular the possibility of initially unreinforced To bring profile bar into any desired final shape, without this being hindered by the reinforcing element becomes. After completion, however, the plastic profile has in each Case the desired strength and stability.
Gegenstand der vorliegenden Erfindung ist auch die Verwendung eines Kunststoff-Profils mit Verstärkungseinlage als Holm und/oder Stufe für Leitern aller Art, beispielsweise für Tritt- und Stehleitern. Solche nur aus isolierenden Materialien wie Kunststoff und Glasfaser hergestellte Leitern sind optimal einsetzbar in Umgebungen mit hohen elektrischen Spannungen oder auch mit explosiven Stoffen.object The present invention is also the use of a plastic profile with reinforcing insert as spar and / or step for Ladders of all kinds, for example for step and step ladders. Such only made of insulating materials such as plastic and fiberglass Ladders are optimally applicable in environments with high electrical voltages or with explosive substances.
