Description
Die Erfindung betrifft einen abstandshaltenden Isolierprofilstab aus thermoplastischem Kunststoff an zweischaligen wärmedämmenden Bauelementen der durch Extrudieren stranggepreßt ist und im Einrollverbund mit zumindest im Bereich des Verbundkontaktes gerändelten Profilen aus einer Aluminiumlegierung verwendet wird, wobei der Isolierprofilstab eine Faserbewehrung aus Glasfasern, Kohlenstoffasern, Metallfasern oder Mischungen davon besitzt.The invention relates to a spacing insulating profile bar made of thermoplastic on double-shell heat-insulating components which are extruded by extrusion is and in the roll-in network with at least in the area of the composite contact knurled profiles from a Aluminum alloy is used, the insulating profile rod a fiber reinforcement made of glass fibers, carbon fibers, Has metal fibers or mixtures thereof.
Zweischalige Bauelemente bezeichnet zwei profilförmige, plattenförmige oder scheibenförmige Bauteile, die mit Hilfe eines Isolierprofilstabes aus thermoplastischem Kunststoff wie beschrieben in Verbund gebracht sind. Als Beispiel für typische zweischalige wärmedämmende Bauelemente werden entsprechend ausgebildete Türrahmen und Fensterrahmen sowie Türzargen und Fensterzargen genannt. Isolierprofilstäbe der beschriebenen Zweckbestimmung müssen in bezug auf mechanische Beanspruchungen sowie in bezug auf thermische Beanspruchungen sehr hohen Anforderungen genügen und darüber hinaus eine ausreichende Wärmeisolierung bewirken. Die mechanischen Beanspruchungen sind festigkeitsmäßige und stabilitätsmäßige Beanspruchungen, aber auch Schubbeanspruchungen im Bereich des Verbandes mit den übrigen Bauteilen der zweischaligen wärmedämmenden Bauelemente (vgl. Mitt. IfBt/1986, S. 197-200). Die Isolierprofilstäbe können als einfachwandige Profile oder als Hohlprofile ausgeführt sein. Die Hohlprofile können aus einfachwandigen Profilen zusammengesetzt sein. Double-shell components are two profile-shaped, plate-shaped or disc-shaped components that with the help an insulating profile rod made of thermoplastic are brought together as described. As an example of Typical double-shell thermal insulation components are made accordingly trained door frames and window frames as well Called door frames and window frames. Insulating profile bars Described purpose must refer to mechanical stresses and in relation to thermal Stresses meet very high requirements and also cause adequate thermal insulation. The mechanical stresses are strength and stability-related loads, but also shear loads in the area of the association with the rest Components of the double-shell heat-insulating components (see Mitt. IfBt / 1986, pp. 197-200). The insulating profile bars can be used as single-walled profiles or as hollow profiles be executed. The hollow profiles can be made of single-walled Profiles.
Ein Isolierstab der eingangs genannten Art ist bekannt (EP-A-0 100 824), wobei aber keine Dimensionierungsangaben gemacht sind. Aus der Praxis bekannte Isolierprofilstäbe der angegebenen Zweckbestimmung, die in zweischalige wärmedämmende Bauelemente integriert sind, besitzen eine den Isolierabstand bestimmende Breite von 8 bis 20 mm. Ihre Wanddicke liegt bei 2,5 mm. Sie können mit Kurzfasern in Form von Glasfasern, Kohlenstoffasern oder Metallfasern bewehrt sein. Die Faserlänge von Kurzfasern ist kleiner als 0,3 mm. Das reicht für eine hohe Isolationswirkung mit einem k-Wert von zwei und weniger nicht aus. Macht man die den Isolierabstand bestimmende Breite beachtlich größer als 20 mm, so muß wegen der aufzunehmenden Beanspruchung die Wanddicke der Isolierprofilstäbe auf über 2,5 mm erhöht werden. Darüber hinaus ist aus Festigkeits- und Stabilitätsgründen eine Erhöhung des Gehaltes an Kurzfasern erforderlich. Das erhöht die Wärmeleitfähigkeit. Das erhöht aber auch die Oberflächenhärte, macht die Oberfläche rauh und beeinträchtigt die Dauerfestigkeit und die Schlagfestigkeit. Im Rahmen der insoweit bekannten Maßnahmen wird folglich keine Verbesserung der Isolierwirkung erreicht, vielmehr muß eine erhebliche Verschlechterung der Isolierwirkung in Kauf genommen werden.An insulating rod of the type mentioned is known (EP-A-0 100 824), but no dimensioning information are made. Insulating profile bars known from practice the specified purpose, which is in double-shell thermal insulation Components are integrated, have a Insulation distance determining width of 8 to 20 mm. Your Wall thickness is 2.5 mm. You can use short fibers in Form of glass fibers, carbon fibers or metal fibers be reinforced. The fiber length of short fibers is less than 0.3 mm. That is enough for a high insulation effect a k value of two and less. Do you do that the width determining the insulation distance is considerably larger than 20 mm, because of the stress to be absorbed Wall thickness of the insulating profile bars increased to over 2.5 mm will. In addition, for reasons of strength and stability an increase in the content of short fibers is required. This increases the thermal conductivity. That increases but also the surface hardness makes the surface rough and affects the fatigue strength and the impact resistance. As part of the measures known so far consequently no improvement in the insulation effect achieved, rather, the insulation effect must deteriorate considerably to be accepted.
Der Erfindung liegt das technische Problem zugrunde, einen abstandshaltenden Isolierprofilstab aus thermoplastischem Kunststoff an zweischaligen wärmedämmenden Bauelementen, der durch Extrudieren hergestellt ist, zu schaffen, welcher bei einem Isolierabstand großer Breite in bezug auf die Isolierwirkung allen Anforderungen genügt. The invention is based on the technical problem, one spacing insulating profile rod made of thermoplastic Plastic on double-shell heat-insulating components, which is made by extrusion to create which with a large isolation distance with respect to the Insulating effect meets all requirements.
Die erfindungsgemäße Lösung dieser Aufgabe ergibt sich aus
folgenden Merkmalen:
Die Erfindung geht von der Erkenntnis aus, daß eine
beachtliche Verbesserung der Isolierwirkung (bis zu einem
k-Wert von unter 2 und beachtlich unter 2) zwar eine
Vergrößerung der dem Isolierabstand bestimmenden Breite des
Isolierprofils verlangen kann, daß jedoch im übrigen die
Wanddicke des Isolierprofilstabes möglichst dünn gehalten
werden sollte. Das läßt sich überraschenderweise erreichen,
wenn in Kombination zu dem Merkmal a) der Patentansprüche 1
und 2 dafür Sorge getragen wird, daß die Fasern die in den
Patentansprüchen 1 und 2 phänomenologisch über den
Quotienten der Wärmeausdehnungen angegebene Orientierung
aufweisen. Dem entspricht eine Anisotropie der
Wärmeausdehnungen, für die der Zahlenwert 0,3 in dem
angegebenen Temperaturbereich eine gute untere Grenze
darstellt, die in Kombination mit den weiteren Merkmalen
den erfindungsgemäß angestrebten Effekt sichert. Ein
solcher Isolierprofilstab kann im Einrollverbund mit den
Profilen aus einer Aluminiumlegierung verwendet werden,
wenn der thermoplastische Kunststoff so eingestellt wird,
daß der Isolierprofilstab im übrigen eine Härte aufweist,
wie es das Merkmal d) der Patentansprüche 1 und 2 angibt.
Überraschenderweise bewirken die im Vergleich zu den
bekannten Maßnahmen längeren und sehr viel längeren Fasern
der Faserbewehrung bei der angegebenen Orientierung eine
ausreichende Festigkeit und Stabilität des
Isolierprofilstabes für die Aufnahme der schon erläuterten
beachtlichen Beanspruchungen. Nichtsdestoweniger ist eine
extreme Härte des Kunststoffes des Isolierprofilstabes
nicht erforderlich, so daß mit dem Merkmal d)
die Voraussetzungen für einen
Einrollverbund mit Profilen aus einer Aluminiumlegierung
gegeben sind. Die Langfasern können auf verschiedene Art
und Weise in den Isolierprofilstab eingebracht werden. So
können dem zu extrudierenden Kunststoff Pellets mit
entwirrbaren Langfasern beigegeben werden. Nach bevorzugter
Ausführungsform der Erfindung wird die Langfaserbewehrung
im Wege der Direktverarbeitung von Endlosfasern
eingebracht. Das stellt sicher, daß die Langfasern sich bei
guter Dispergierung verteilen (vergl. Truckenmüller IKT,
"Direktverarbeitung von Endlosfasern ..." und DE 40 16 784
C2, DE 42 36 662 A1).The invention is based on the knowledge that a
considerable improvement in the insulation effect (up to one
k value of less than 2 and considerably less than 2)
Enlargement of the width of the insulation distance
Insulating profile may require that, however, the rest
Wall thickness of the insulating profile bar kept as thin as possible
should be. Surprisingly, this can be achieved

oder Mischungen davon bestehen. Wird mit Glasfasern
gearbeitet, so können Kohlenstoffasern oder Metallfasern
zur Einstellung der elektrischen Leitfähigkeit beigemischt
werden. Die Langfaserbewehrung in dem Isolierprofilstab
macht etwa 10 bis 45 Masse% aus. Der Extrusionsvorgang
wurde so geführt, daß die Fasern nach Maßgabe der Angaben
über die Wärmeausdehnung in den Patentansprüchen 1 und 2
orientiert sind. Im Ausführungsbeispiel beträgt die den
Isolierabstand bestimmende Breite des Isolierprofils etwa
30 mm. In bezug auf die Wanddicke wird auf die
Patentansprüche 6 und 7 verwiesen. Die Länge der Langfasern
der Langfaserbewehrung 3 liegt im Bereich von 3 bis 15 mm.
Aus Maßstabsgründen ist nicht erkennbar, daß die
Faserbewehrung 3 eine Beimischung von Fasern mit einer
Länge von unter 3 mm aufweist, jedoch in dem
verhältnismäßig geringen Menge, die im Patentanspruch 1
festgelegt ist. Der Kunststoff kann auch eine Beimischung aus
feinteiligen mineralischen Füllstoffen aufweisen, was aus
Maßstabsgründen ebenfalls nicht erkennbar ist. Das gilt
auch für die Dicke der Langfasern, zu der auf den Patentanspruch

Um beim Extrudieren eines Profilstabes mit Faserbewehrung die Fasern zu orientieren, sind zahlreiche Maßnahmen bekannt, die auch zur Herstellung erfindungsgemäßer Isolierprofilstäbe eingesetzt werden können. Nur beispielsweise wird verwiesen auf das aus der DE 38 01 574 A1 bekannte Verfahren oder auf das sogenannte Monsanto-Verfahren.To when extruding a profile bar with fiber reinforcement To orient the fibers, numerous measures are known which also for the production of insulating profile bars according to the invention can be used. Just for example reference is made to that known from DE 38 01 574 A1 Process or the so-called Monsanto process.
