Abstract

1. A profiled strip consisting of plastic provided with reinforcing additives in the form of fibres, more particularly for the production of window frames, comprising a plurality of outer and reinforcing walls which extend along the profile and form hollow chambers, characterized in that up to 20 % by weight of glass fibres or up to 40 % by weight of fibre material having no glass content, such as carbon, plastic or ceramic fibres, is mixed with the plastic forming the outer and reinforcing walls (10, 12, 14) and at least the or each hollow chamber (18) which is subjected to impact stress and/or defined by the outer wall (10) forming the outside of the window frame is completely filled with a plastic member (16) consisting of plastic having substantially no reinforcing additives.

Description

Die Erfindung betrifft eine Profilleiste aus mit verstärkenden Zusätzen in Form von Fasern versehenem Kunststoff, insbesondere für die Herstellung von Fensterrahmen, mit einer Mehrzahl von sich längs des Profils erstreckenden, Hohlkammern bildenden Außen-und Versteifungswandungen sowie ein Verfahren zur Herstellung einer solchen Kunststoff-Profilleiste.The invention relates to a profile strip made of plastic provided with reinforcing additives in the form of fibers, in particular for the production of window frames, with a plurality of outer and stiffening walls which extend along the profile and form hollow chambers, and a method for producing such a plastic profile strip.

Hohlprofile zum Herstellen von Fenster- und Türrahmen aus Kunststoff sind seit langem bekannt.Hollow profiles for the production of window and door frames made of plastic have long been known.

Bei derartigen Hohlprofilen stellt sich das Problem, daß insbesondere bei großflächigen Fenster- bzw. Türöffnungen die Stabilität nicht ausreichend ist und bei erhöhter Wärmeaufnahme (Verwendung dunkelfarbiger Profile bzw. Einsatz in wärmeren Klimazonen) Funktionsproblem durch Längenausdehnung und starkes Absinken des Elastizitätsmodules entstehen können. Zunächst wurde versucht, durch die Einbringung von Holz-, Stahl- oder Aluminiumstreben das Hohlprofil zu versteifen. Es hat sich jedoch gezeigt, daß derartige verstärkungsstreben die Herstellung und Weiterverarbeitung von Profilleisten erschweren und verteuern und daher unwirtschaftlich sind.The problem with such hollow profiles is that the stability is not sufficient, especially with large window or door openings, and with increased heat absorption (use of dark-colored profiles or use in warmer climates), functional problems may arise due to length expansion and a sharp drop in the elasticity module. Initially, attempts were made to stiffen the hollow profile by introducing wooden, steel or aluminum struts. However, it has been shown that such reinforcing struts make the manufacture and further processing of profile strips more difficult and expensive and are therefore uneconomical.

Es ist weiter versucht worden, die Festigkeit derartiger Profilleisten durch Füllungen mit Kunststoff zu versteifen (DE-PS-1 086 032, DE-OS-2 827 851, DE-OS-2 326 911, EU-OS-0 053 662). Weiter ist es bekannt, kunstharzgebundene Glasfaserbänder in oder auf die Außenwände von Profilleisten aus Kunststoff aufzubringen (DE-GM-8 111 425).Attempts have also been made to stiffen the strength of such profiled strips by means of fillings with plastic (DE-PS-1 086 032, DE-OS-2 827 851, DE-OS-2 326 911, EU-OS-0 053 662). It is also known to apply synthetic resin-bonded glass fiber tapes in or on the outer walls of plastic profile strips (DE-GM-8 111 425).

Aus der deutschen Gebrauchsmusterschrift 8 202 221 schließlich ist es bekannt, die mechanische Festigkeit und Steifigkeit von Profilleisten aus Kunststoff dadurch zu verbessern, daß dem Kunststoffmaterial, aus dem die Profilleiste durch Extrusion hergestellt wird, Glasfasern beigegeben werden. Eine solche Beimengung von Glasfasern verbessert zwar die Steifigkeit der Kunststoff-Profilleisten ganz wesentlich, sie hat jedoch bedeutende Nachteile: Durch die Beimengung von verstärkenden Zusätzen wird die Kälteschlagzähigkeit deutlich herabgesetzt, Hohlprofilleisten mit einem relativ hohen Anteil von verstärkenden Zusätzen wie Glasfasern sind also - insbesondere bei Kälte - mechanischen Beanspruchungen gegenüber nicht ausreichend widerstandsfähig. Zwar kann die Kälteschlagzähigkeit durch die Zugabe sogenannter Modifier wieder verbessert werden, solche Modifier verteuern jedoch das herzustellende Produkt erheblich. Weiter senken sie den Elastizitätsmodul, so daß bei Wärme die Formstabilität unzureichend ist, auch verschlechtern sie die Schweißfähigkeit des Kunsttoffes, die für die Herstellung von Eckverbindungen wesentlich ist, und schließlich verringern diese Modifier auch die Wirkung der verstärkenden Zusätze.Finally, it is known from German utility model 8 202 221 to improve the mechanical strength and rigidity of plastic profile strips by adding glass fibers to the plastic material from which the profile strip is produced by extrusion. Such an admixture of glass fibers improves the rigidity of the plastic profile strips considerably, but it has significant disadvantages: the addition of reinforcing additives significantly reduces the cold impact strength, so hollow profile strips with a relatively high proportion of reinforcing additives such as glass fibers are - especially with Cold - not sufficiently resistant to mechanical stress. Although the cold impact strength can be improved again by adding so-called modifiers, such modifiers make the product to be manufactured considerably more expensive. They further reduce the modulus of elasticity, so that the heat is insufficient in shape stability, they also deteriorate the weldability of the plastic, which is essential for the production of corner joints, and finally these modifiers also reduce the effect of the reinforcing additives.

In der zuletzt genannten Gebrauchsmusterschrift wird daher vorgeschlagen, zur Überwindung der genannten Nachteile die Profilleiste zweischichtig aufzubauen, wobei das Kernprofil aus einem Polyvinylchlorid mit mehr als etwa 30 Gew.-% Glasfasern besteht und eine Ummantelung aus einem mit dem PVC verträglichen, die Schlagfestigkeit des Kernprofils übertreffenden Kunststoff verbunden ist.In the last-mentioned utility model specification, it is therefore proposed to build up the profile strip in two layers in order to overcome the disadvantages mentioned, the core profile consisting of a polyvinyl chloride with more than about 30% by weight of glass fibers and a sheathing made of an impact resistance of the core profile which is compatible with the PVC superior plastic is connected.

Es versteht sich, daß ein derartiger zweischichtiger Aufbau einer Profilleiste ein aufwendiges Herstellungs verfahren voraussetzt. Nachteilig ist weiter, daß die einen hohen Anteil von Glasfasern aufweisenden Kernprofile schlecht miteinander verschweißbar sind.It is understood that such a two-layer structure of a profile strip requires a complex manufacturing process. Another disadvantage is that the core profiles, which have a high proportion of glass fibers, are difficult to weld together.

Der Erfindung liegt damit die Aufgabe zugrunde, die eingangs genannte Profilleiste, deren Festigkeit durch die Verwendung von mit verstärkenden Zusätzen versehenen Kunststoff ausreichend gut ist, derart auszugestalten, daß eine ausreichende Kälteschlagfestigkeit erreicht wird und daß die durch die Zusätze verschlechterte Verschweißbarkeit des Kunststoffes sich nicht nachteilig auswirkt.The invention is therefore based on the object, the initially mentioned profile strip, the strength of which is sufficiently good through the use of plastic provided with reinforcing additives, in such a way that sufficient resistance to cold impact is achieved and that the weldability of the plastic, which is impaired by the additives, is not disadvantageous affects.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß dem die Außen- und Versteifungswandungen bildenden Kunstotoff bis zu 20 Gew.-% Glasfasern oder bis zu 40 Gew.-% glasfreien Fasermaterials wie Kohlenstoff-, Kunststoff- oder Keramikfasern beigemengt ist und daß wenigstens die auf Schlag beanspruchte(n) und/oder die von der die Fensterrahmenaußenseite bildende Außenwandung begrenzte(n) Hohlkammer(n) vollständig mit einem Kunststoffkörper aus einem im wesentlichen keine verstärkende Zusätze aufweisenden Kunststoff gefüllt ist (sind).According to the invention, this object is achieved in that up to 20% by weight of glass fibers or up to 40% by weight of glass-free fiber material such as carbon, plastic or ceramic fibers is added to the plastic forming the outer and stiffening walls, and that at least those in one go claimed (s) and / or the hollow chamber (s) bounded by the outer wall forming the outside of the window frame is (are) completely filled with a plastic body made of a plastic which has essentially no reinforcing additives.

Als Kunststoff für die Außen- und Versteifungswandungen kommen verschiedene thermoplastische Kunststoffe in Betracht, insbesondere aber Polyvinylchlorid. Die den die Außen- und Versteifungswandungen bildenden Kunststoff beigegebenen Glasfasern weisen vorzugsweise einen Durchmesser zwischen 2 und 25 11m und eine Stapellänge bis zu 15 mm auf.Various thermoplastics come into consideration as plastic for the outer and stiffening walls, but especially polyvinyl chloride. The point which the outer and Versteifungswandungen plastic forming accompanying glass fibers preferably have a diameter 2-25 1 1m and a staple length mm up to 15 °.

Vorzugsweise ist vorgesehen, daß der bzw. die die Hohlkammer bzw. Hohlkammern ausfüllenden Kunststoffkörper aus einem Schaumkunststoff bestehen. Dabei kann das Grundmaterial des den bzw. die Hohlkammern ausfüllenden Kunststoffes dem Grundmaterial des die Außen- und Versteifungswandungen bildenden Kunststoffes entsprechen.It is preferably provided that the plastic body or bodies filling the hollow chamber or hollow chambers consist of a foam plastic. The base material of the plastic filling the hollow chamber or cavities can correspond to the base material of the plastic forming the outer and stiffening walls.

Besonders bewährt hat sich eine Ausgestaltung, bei der die Wanddicke der Außenwandungen zwischen 0,2 bis 10,0 mm, vorzugsweise zwischen 2,0 und 4,0 mm und die Tiefe der von dieser begrenzten, mit dem Kunststoffkörper gefüllten Hohlkammer bis zu 15 mm beträgt.An embodiment has proven particularly useful in which the wall thickness of the outer walls is between 0.2 to 10.0 mm, preferably between 2.0 and 4.0 mm, and the depth of the hollow chamber delimited by the latter and filled with the plastic body is up to 15 mm is.

Bei der Herstellung des erfindungsgemäßen Kunststoffprofils werden der bzw. die die Hohlkammer bzw. die Hohlkammern füllenden Kunststoffkörper vorzugsweise gemeinsam mit den Außen- und Versteifungswandungen extrudiert. Eine derartige Coextrusion bewirkt eine besonders gute Verbindung des Kunststoffkörpers mit den die Hohlkammer begrenzenden Außen- bzw. Versteifungswandungen.In the production of the plastic profile according to the invention, the plastic body (s) filling the hollow chamber or cavities are preferably used together extruded the outer and stiffening walls. Such a coextrusion brings about a particularly good connection of the plastic body to the outer or stiffening walls delimiting the hollow chamber.

Die Herstellung einer Eckverbindung zwischen erfindungsgemäß ausgestalteten Kunststoffprofilen wird durch Verschweißen insbesondere der die Hohlkammer bzw. Hohlkammern füllenden Kunststoffkörper ermöglicht. Alternativ ist es jedoch auch möglich, die Kunststoffkörper einzufräsen, in die Einfräsungen Lochblechwinkel einzubringen und diese anschließend mittels geeigneter Klerber, insbesondere mittels Ausschäumen, der Einfräsung mit Polyurethanschaum zu verkleben.The production of a corner connection between plastic profiles designed according to the invention is made possible by welding, in particular, the plastic body filling the hollow chamber or hollow chambers. Alternatively, however, it is also possible to mill the plastic body, to insert perforated sheet metal angles into the millings and then to glue the millings with polyurethane foam using suitable clinkers, in particular by means of foaming.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen, der Beschreibung und der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist. Dabei zeigt:

  • Fig. 1 die erfindungsgemäße Profilleiste in einem ersten Ausführungsbeispiel;
  • Fig. 2 die erfindungsgemäße Profilleiste nach einem zweiten Ausführungsbeispiel.
Further features and advantages of the invention result from the claims, the description and the drawing, in which an exemplary embodiment is shown. It shows:
  • Figure 1 shows the profile strip according to the invention in a first embodiment.
  • Fig. 2 shows the profile strip according to the invention according to a second embodiment.

Figur 1 zeigt die Profilleiste mit einer Mehrzahl von Außenwandungen 10, 12 und Versteifungswandungen 14. Die Außen- und Versteifungswandungen 10, 12, 14 bilden eine Mehrzahl von Hohlkammern 18. Der Hohlraum 16, der durch die die Fensterrahmenaußenseite bildende Außenwandung 10 begrenzt wird, ist vollständig mit einem Kunststoffkörper 16 gefüllt. Während das Material der Außenwandung 10, 12 - ebenso wie das Material der Versteifungswandungen 14 - mit einem verstärkenden Zusatz aus bis zu 20 Gew.-% Glasfasern bzw. bis zu 40 Gew.-% eines glasfreien Fasermaterials wie Kohlenstoff-, Kunststoff- oder Keramikfasern besteht, besteht der Kunststoffkörper 16 aus einem Kunststoff, welcher im wesentlichen keine verstärkenden Zusätze aufweist. Wegen der verstärkenden Zusätze in den Außen- und Versteifungswandungen 10, 12, 14 hat die erfindungemäße Profilleiste eine ausreichende Eigenstabilität, zu der der Kunststoffkörper 16 nur unwesentlich beiträgt. Der Kunststoffkörper 16 hat dagegen die Funktion, die Kälteschlagfestigkeit der Außenwandung 10 zu erhöhen: Bei mechanischer Beanspruchung der Außenwandung 10 nämlich wird die auf diese auftreffende Schlagenergie von dem Kunststoffkörper 16 aufgefangen, was trotz der relativ hohen Kältesprödigkeit des Material eine hohe Rißfestigkeit der Außenwandung 10 bewirkt.Figure 1 shows the profile strip with a plurality of outer walls 10, 12 and stiffening walls 14. The outer and stiffening walls 10, 12, 14 form a plurality of hollow chambers 18. The cavity 16, which is delimited by the outer wall 10 forming the outside of the window frame, is completely filled with a plastic body 16. While the material of the outer wall 10, 12 - like the material of the stiffening walls 14 - with a reinforcing addition of up to 20% by weight of glass fibers or up to 40% by weight of a glass-free fiber material such as carbon, plastic or ceramic fibers consists, the plastic body 16 consists of a plastic which has essentially no reinforcing additives. Because of the reinforcing additives in the outer and stiffening walls 10, 12, 14, the profile strip according to the invention has sufficient inherent stability, to which the plastic body 16 contributes only insignificantly. The plastic body 16, on the other hand, has the function of increasing the cold impact strength of the outer wall 10: namely, when the outer wall 10 is subjected to mechanical stress, the impact energy that impinges on it is absorbed by the plastic body 16, which, despite the relatively high brittleness of the material, results in a high crack resistance of the outer wall 10 .

Es versteht sich, daß die geometrischen Verhältnisse zwischen der Außenwandung 10 und dem Kunststoffkörper 12 richtig gewählt werden müssen. Einerseits wird das erfindungsgemäße Ziel natürlich durch eine große Dicke des Kunststoffkörpers 16 gefördert, andererseits hat dies Kostennachteile. Es hat sich gezeigt, daß bei einer Dicke von 2,0 bis 4,0 mm der Außenwandung die Dicke des Kunststoffkörpers 16 15 mm nicht zu übersteigen braucht.It is understood that the geometric relationships between the outer wall 10 and the plastic body 12 must be chosen correctly. On the one hand, the goal according to the invention is naturally promoted by a large thickness of the plastic body 16, on the other hand, this has cost disadvantages. It has been shown that with a thickness of 2.0 to 4.0 mm of the outer wall, the thickness of the plastic body 16 need not exceed 15 mm.

Wichtig ist weiter eine gute Verbindung zwischen der Außenwandung 10 und dem Kunststoffkörper 16, da schon ein sehr kleiner Zwischenraum zwischen dem Kunststoffkörper 16 und der Außenwandung 10 bei mechanischer Beanspruchung eine Rißbildung in der Außenwandung 10 bewirken kann. Der Ausbildung eines derartigen Zwischenraumes wird dadurch besonders gut entgegengewirkt, daß das Grundmaterial des Kunststoffkörpers 16 dem Grundmaterial des mit verstärkenden Zusätzen versehenen Kunststoffes der Außenwandung 10 entspricht und daß beide gleichzeitig extrudiert werden, weil dadurch eine feste Verbindung beider Werkstoffe gewährleistet wird.It is also important to have a good connection between the outer wall 10 and the plastic body 16, since even a very small space between the plastic body 16 and the outer wall 10 can cause cracks to form in the outer wall 10 when subjected to mechanical stress. The formation of such an intermediate space is counteracted particularly well in that the base material of the plastic body 16 corresponds to the base material of the plastic of the outer wall 10 provided with reinforcing additives and that both are extruded at the same time, because this ensures a firm connection of the two materials.

Das Ausführungsbeispiel von Figur 2 unterscheidet sich von dem von Figur 1 lediglich dadurch, daß eine Folie 20 oder eine farbige oder transparente Lackschicht auf die Außenseite der Außenwandung 10 aufgebracht ist. Diese Kunststoffolie bzw. Lackschicht 20 schützt die Außenwandung 10 vor dem schädigenden Einfluß von Lichtstrahlen und ermöglicht es damit, auf den Zusatz von speziellen Pigmenten in dem Kunststoffmaterial zu verzichten.The embodiment of Figure 2 differs from that of Figure 1 only in that a film 20 or a colored or transparent lacquer layer is applied to the outside of the outer wall 10. This plastic film or lacquer layer 20 protects the outer wall 10 from the damaging influence of light rays and thus makes it possible to dispense with the addition of special pigments in the plastic material.

Die in der vorstehenden Beschreibung, der Zeichnung sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausgestaltungen wesentlich sein.The features of the invention disclosed in the above description, the drawing and in the claims can be essential both individually and in any combination for realizing the invention in its various configurations.
