  • thermoplastic materials are widely used for the production of plastic windows and plastic doors. They usually have several hollow chambers, which are delimited from each other by inner webs. These profiles are predominantly produced by extrusion from rigid PVC (PVC-U).

This is followed by cooling and calibration of the hollow chamber profiles. For an economic production of the hollow chamber profiles high extrusion and cooling rates are required. In addition, this method leads to residual stresses in the hollow chamber profiles, which lead to a distortion of the hollow chamber profiles produced in this way. Due to this distortion, windows and doors made of hollow profiles made of thermoplastic materials can only be produced to a lesser extent than corresponding windows or doors made of other materials.

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Hohlkammerprofils für ein Fenster oder eine Tür sowie ein Hohlkammerprofil für ein Fenster oder eine Tür, das nach einem Verfahren nach einem derartigen Verfahren hergestellt worden ist. The present invention relates to a method for producing a hollow chamber profile for a window or a door and a hollow chamber profile for a window or a door, which has been produced by a method according to such a method.
Hohlkammerprofile aus thermoplastischem Kunststoff werden in großem Umfang zur Her- stellung von Kunststofffenstern und Kunststofftüren eingesetzt. Sie weisen in der Regel mehrere Hohlkammern auf, die durch Innenstege voneinander abgegrenzt sind. Diese Pro- file werden ganz überwiegend durch Extrusion aus Hart-PVC (PVC-U) hergestellt. Dabei wird der thermoplastische Kunststoff zunächst geschmolzen und durch ein entsprechendes Formwerkzeug gepresst, wodurch dem thermoplastischen Kunststoff die Form des Hohl- kammerprofils verliehen wird. Danach erfolgt eine Abkühlung und Kalibrierung der Hohl- kammerprofile. Für eine wirtschaftliche Herstellung der Hohlkammerprofile sind hohe Extrusions- und Abkühlgeschwindigkeiten erforderlich. Darüber hinaus führt dieses Verfah- ren zu Eigenspannungen in den Hohlkammerprofilen, die zu einem Verzug der so herge- stellten Hohlkammerprofile führen. Aufgrund dieses Verzugs können Fenster und Türen aus Hohlkammerprofilen aus thermoplastischen Kunststoffen nur in geringerer Größe her- gestellt werden als entsprechende Fenster oder Türen aus anderen Werkstoffen. Hollow-chamber profiles made of thermoplastic material are widely used for the production of plastic windows and plastic doors. They usually have several hollow chambers, which are delimited from each other by inner webs. These profiles are predominantly produced by extrusion from rigid PVC (PVC-U). In this case, the thermoplastic material is first melted and pressed by a corresponding molding tool, whereby the thermoplastic resin is given the shape of the hollow chamber profile. This is followed by cooling and calibration of the hollow chamber profiles. For an economic production of the hollow chamber profiles high extrusion and cooling rates are required. In addition, this method leads to residual stresses in the hollow chamber profiles, which lead to a distortion of the hollow chamber profiles produced in this way. Due to this distortion, windows and doors made of hollow profiles made of thermoplastic materials can only be produced to a lesser extent than corresponding windows or doors made of other materials.
An dieser Stelle setzt die vorliegende Erfindung ein, der die Aufgabe zugrunde liegt, ein Verfahren zur Herstellung eines Hohlkammerprofils für ein Fenster oder eine Tür zur Ver- fügung zu stellen, das die Nachteile des Stands der Technik überwindet. Insbesondere soll das nach dem erfindungsgemäßen Verfahren hergestellte Hohlkammerprofil für ein Fenster oder eine Tür wirtschaftlicher hergestellt werden können und einen verringerten Verzug besitzen. Darüber hinaus liegt die Aufgabe der vorliegenden Erfindung in der Bereitstellung eines Hohlkammerprofils für ein Fenster oder eine Tür, das nach einem Verfahren nach einem derartigen Verfahren hergestellt worden ist. At this point, the present invention is based on the object of providing a method for producing a hollow chamber profile for a window or a door, which overcomes the disadvantages of the prior art. In particular, the hollow chamber profile produced by the process according to the invention for a window or door should be made more economical and have a reduced distortion. Moreover, the object of the present invention is to provide a hollow chamber profile for a window or a door, which has been produced by a method according to such a method.
Diese und andere Aufgaben werden erfindungsgemäß durch ein Verfahren zur Herstellung eines Hohlkammerprofils für ein Fenster oder eine Tür mit den Merkmalen des Anspruchs 1 oder durch ein Hohlkammerprofil mit den Merkmalen des Anspruchs 12 gelöst. Bevorzugte l Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen be- schrieben. These and other objects are achieved by a method for producing a hollow chamber profile for a window or a door with the features of claim 1 or by a hollow chamber profile with the features of claim 12. Preferred l Embodiments of the present invention are described in the dependent claims.
Gemäß der vorliegenden Erfindung wurde überaschenderweise erkannt, dass die Herstel- lungsgeschwindigkeit eines Hohlkammerprofils deutlich gegenüber der eines herkömmli- chen Hohlkammerprofils gesteigert werden kann, wenn die Herstellung derart erfolgt, dass zunächst einzelne Teilprofile des Hohlkammerprofils, beispielsweise durch Extrusion, her- gestellt werden und die Einzelteile anschließend miteinander verbunden werden. Die klei- neren Teilprofile können deutlich schneller abgekühlt und besser kalibriert werden, weil sich in den Teilprofilen Wandungen kalibrieren lassen, die in einem einstückigen Hohlkammer- profil einer Kalibrierung nicht zugänglich sind. Dadurch kann die Herstellung der Profile schneller und wirtschaftlicher bei geringerem Verzug der Hohlkammerprofile erfolgen. Dar über hinaus lässt sich durch die Herstellung der Teilprofile die Qualität der erhaltenen Hohlkammerprofile insbesondere in Bezug auf die gewünschten geometrischen Eigen- schaften (z.B. Geradheit, Wanddicken und dergleichen) verbessern. Surprisingly, according to the present invention, it has been recognized that the production rate of a hollow chamber profile can be significantly increased compared to that of a conventional hollow chamber profile if the production takes place in such a way that first individual partial profiles of the hollow chamber profile are produced, for example by extrusion, and the Individual parts are then connected to each other. The smaller sub-profiles can be cooled much faster and calibrated better because walls can be calibrated in the sub-profiles that are inaccessible to calibration in a one-piece hollow chamber profile. As a result, the production of the profiles can be done faster and more economically with less distortion of the hollow chamber profiles. In addition, the production of the sub-profiles can improve the quality of the obtained hollow-chamber profiles, in particular with regard to the desired geometrical properties (for example straightness, wall thicknesses and the like).
Dementsprechend liegt der vorliegenden Erfindung in der Bereitstellung eines Verfahrens zur Herstellung eines Hohlkammerprofils für ein Fenster oder eine Tür, das aus mehreren Teilprofilen aufgebaut ist und mindestens ein Teilprofil einen thermoplastischen Kunststoff umfasst, wobei der thermoplastische Kunststoff zumindest teilweise die Innenwände und die Außenwände des Hohlkammerprofils bildet und die Innenwände und die Außenwände die Hohlkammern des Hohlkammerprofils umgeben, wobei das Verfahren die folgenden Stufen (a) des Bereitstellen von mindestens zwei Teilprofilen; und (b) des Verbindens der in Stufe (a) bereitgestellten Teilprofile unter Bildung des Hohlkammerprofils umfasst. Accordingly, the present invention is to provide a method for producing a hollow chamber profile for a window or a door, which is constructed from a plurality of sub-profiles and at least one partial profile comprises a thermoplastic material, wherein the thermoplastic material at least partially forms the inner walls and the outer walls of the hollow chamber profile and the inner walls and the outer walls surround the hollow chambers of the hollow chamber profile, the method comprising the following steps (a) of providing at least two partial profiles; and (b) connecting the sub-profiles provided in step (a) to form the hollow-chamber profile.
Wie hierin verwendete bezieht sich der Ausdruck„aus mehreren Teilprofilen aufgebaut“ auf den Aufbau des Hohlkammerprofils selbst. Es soll ausdrücklich nicht beinhalten, dass an das Hohlkammerprofil weitere Profile angebracht werden, wie beispielsweise Glasleisten, Blendrahmenverbreiterungen, Vorsatzschalen oder dergleichen. As used herein, the phrase "composed of multiple sub-profiles" refers to the structure of the hollow section itself. It is not intended to specifically contemplate that additional profiles be applied to the wall section, such as glazing beads, frame extensions, shells, or the like.
In Bezug auf das erfindungsgemäße Verfahren hat es sich als günstig erwiesen, wenn das Bereitstellen der Teilprofile in Stufe das Herstellen von mindestens einem der Teilprofile durch Extrusion oder Coextrusion umfasst. Bevorzugt ist mindestens eines der Teilprofile oder es sind beide Teilprofile aus Polyvinylchlorid (PVC) hergestellt, insbesondere aus Hart-PVC (PVC-U) oder glasfaserverstärktem PVC, das auch nachchloriertes PVC (PVC- C) enthalten kann. Insbesondere für Teilprofile aus thermoplastischem Kunststoff stellt die Extrusion eine effektive Herstellungsmöglichkeit dar. Dabei kann der gesamte Querschnitt des Teilprofils aus demselben thermoplastischen Kunststoff aufgebaut sein oder der Quer- schnitt des Teilprofils kann aus verschiedenen thermoplastischen Kunststoffen aufgebaut sein, beispielsweise ein Kernprofil aus glasfaserverstärktem PVC mit einer Ummantelung aus Hart-PVC oder ein Kernprofil aus recycliertem PVC mit einer Ummantelung aus neuem Hart-PVC. Es kann auch durch Coextrusion eine Dichtung aus Weich-PVC oder TPE mit- tels Coextrusion oder Postcoextrusion an das jeweilige Teilprofil anextrudiert werden. With regard to the method according to the invention, it has proved to be advantageous if the provision of the sub-profiles in step comprises the production of at least one of the sub-profiles by extrusion or coextrusion. Preference is given to at least one of the sub-profiles or both sub-profiles are made of polyvinyl chloride (PVC), in particular of rigid PVC (PVC-U) or glass-fiber reinforced PVC, which also contains postchlorinated PVC (PVC). C). In particular, for sub-profiles of thermoplastic material, the extrusion is an effective manufacturing option. The entire cross-section of the sub-profile may be constructed of the same thermoplastic or the cross-section of the sub-profile may be constructed of different thermoplastic materials, such as a core profile of glass fiber reinforced PVC with a Hard PVC sheath or recycled PVC core with a new hard PVC sheath. Coextrusion can also be used to extrude a seal made of soft PVC or TPE by means of coextrusion or postcoextrusion onto the respective subprofile.
Das Verbinden der Teilprofile in Stufe (b) kann erfindungsgemäß vorzugsweise stoffschlüs- sig, insbesondere durch Verkleben oder Verschweißen, erfolgen. Alternativ dazu kann Ver- binden der Teilprofile in Stufe (b) kann erfindungsgemäß bevorzugt auch durch Verrasten und/oder unter Verwendung von Verbindungsmitteln, insbesondere von Schrauben, Nieten, Bolzen oder dergleichen, erfolgen. The bonding of the sub-profiles in step (b) can according to the invention preferably be made of a material, in particular by gluing or welding. Alternatively, bonding of the sub-profiles in step (b) can, according to the invention, preferably also take place by latching and / or by using connecting means, in particular screws, rivets, bolts or the like.
Es kann auch von Vorteil sein, wenn die Teilprofile aus gleichen Werkstoffen oder aus un- terschiedlichen Werkstoffen aufgebaut sind. Teilprofile aus unterschiedlichen Werkstoffen ermöglichen die Herstellung von Verbundprofilen, die bei einer einstückigen Herstellung des Hohlkammerprofils oder nur sehr aufwändig hergestellt werden können. Dadurch kön- nen beispielsweise solche Teilprofile hergestellt werden, die dem dieses enthaltenden Hohlkammerprofil funktionelle Eigenschaften gegenüber den anderen Teilprofilen verleihen, z.B. eine höhere Steifigkeit, eine höhere Wärmeformbeständigkeit, bessere Wärmedäm- mungseigenschaften und dergleichen. Beispielsweise kann ein Teilprofil aus Stahl gefertigt sein, während ein zweites Teilprofil aus thermoplastischem Kunststoff, beispielsweise Hart- PVC, extrudiert wurde. Die beiden Teilprofile werden anschließend beispielsweise durch Verkleben zu einem erfindungsgemäßen Hohlkammerprofil verbunden. In dem erhaltenen erfindungsgemäßen Hohlkammerprofil übernimmt das Teilprofil aus Stahl die Aufgabe der Armierung, während das Teilprofil aus thermoplastischem Kunststoff die Funktionsmaße für die Funktion des Hohlkammerprofils, wie beispielsweise Farbe, Falzmaß, Dichtungsauf- nahme und dergleichen, definiert. Dadurch wird in einem derartigen erfindungsgemäßen Hohlkammerprofil die klassisch eingesetzte Stahlarmierung durch das Teilprofil aus Stahl ersetzt und ist daher nicht mehr erforderlich. Stahlarmierungen werden im Stand der Tech- nik in die Armierungskammer eines einstückig hergestellten Hohlkammerprofils eingescho- ben und durch Verschrauben mit dem Hohlkammerprofil verbunden. Durch diese Verbin- dungstechnik kann die Stahlarmierung aufgrund einer Lochlaibung im Bereich der Ver- Schraubung und den zum Einschieben der Armierung erforderlichen Toleranzen der Armie- rungskammer ihre Steifigkeit nur begrenzt zur Wirkung bringen. It can also be advantageous if the sub-profiles are made of the same materials or of different materials. Sub-profiles made of different materials allow the production of composite profiles, which can be produced in a one-piece production of the hollow chamber profile or only with great effort. As a result, it is possible, for example, to produce subprofiles which impart functional properties to the hollow section containing the latter in comparison with the other subprofiles, for example a higher rigidity, a higher heat resistance, better thermal insulation properties and the like. For example, a partial profile may be made of steel, while a second partial profile of thermoplastic material, such as rigid PVC, has been extruded. The two sub-profiles are then connected, for example, by gluing to a hollow chamber profile according to the invention. In the obtained hollow chamber profile according to the invention, the partial profile made of steel takes on the task of reinforcement, while the partial profile of thermoplastic material defines the functional dimensions for the function of the hollow chamber profile, such as color, rebate dimension, seal acceptance and the like. As a result, in such a hollow chamber profile according to the invention the classically used steel reinforcement is replaced by the partial profile made of steel and is therefore no longer necessary. Steel reinforcements are pushed in the state of the art into the reinforcing chamber of an integrally produced hollow-chamber profile and connected by screwing to the hollow-chamber profile. Due to this connection technique, the steel reinforcement can, due to a hole reveal in the area of the Screwing and the required for insertion of the reinforcement tolerances of the armouring chamber bring their rigidity only to a limited effect.
Es kann auch von Vorteil sein, wenn mindestens eines der Teilprofile mindestens eine im Profilquerschnitt einseitig offene Hohlkammer aufweist, die durch das Verbinden der Teil- profile in Stufe (b) geschlossen wird. Auf diese Weise lassen sich Funktionselemente in Hohlkammer des erfindungsgemäßen Hohlkammerprofils einbringen, die bei herkömmli- chen einstückigen Hohlkammerprofilen nicht, nicht so leicht oder nicht gleichmäßig zugäng- lich sind. It may also be advantageous if at least one of the sub-profiles has at least one hollow chamber which is open on one side in the profile cross-section and which is closed by connecting the sub-profiles in stage (b). In this way, functional elements can be introduced into the hollow chamber of the hollow chamber profile according to the invention, which are not accessible, not so easy or not uniformly accessible in the case of conventional one-piece hollow-chamber profiles.
Wie hierin verwendet bezieht sich der Begriff„einseitig offene Hohlkammer“ auf Hohlkam- mern, die im Profilquerschnitt an einer Seite zumindest teilweise zum Profiläußeren hin offen sind. Gleichermaßen bezieht sich der Begriff„geschlossenes Hohlkammerprofil“ oder der Begriff„geschlossene Hohlkammer“, wie hierin verwendet, wiederum auf den Profil querschnitt. Die Begriffe beziehen sich explizit nicht auf die offenen Profilseiten an den bei- den Profilenden. As used herein, the term "hollow chamber open on one side" refers to hollow chambers that are at least partially open in the profile cross-section on one side to the outside of the profile. Likewise, the term "closed hollow section" or the term "closed section" as used herein again refers to the profile section. The terms explicitly do not refer to the open profile pages at the two profile ends.
In diesem Zusammenhang kann es auch von Nutzen sein, wenn das Verfahren vor Stufe (b) weiter die Stufe des Aufbringens einer niedrigemittierenden Beschichtung und/oder ei- ner niedrigemittierenden Folie auf mindestens eine der die einseitig offenen Hohlkammern des Hohlkammerprofils umgebenden Außenwände und/oder Innenwände umfasst, wobei die einseitig offene Hohlkammer durch das Verbinden der Teilprofile in Stufe (b) geschlos- sen wird. Dadurch kann der Wärmedurchgang durch ein erfindungsgemäßes Hohlkammer- profil signifikant reduziert werden. Niedrigemittierende Beschichtungen (auch als„Low-e- Beschichtungen“ bezeichnet) und niedrigemittierenden Folien (auch als„Low-e-Folien“ be- zeichnet) weisen bei hohem Transmissiongrad im sichtbaren Teil des elektromagnetischen Spektrums im infraroten Spektralbereich eine hohe Reflexion und damit verbunden eine niedrige Emissivität (low emissivity) auf. Dementsprechend haben niedrigemittierende Be- schichtungen und niedrigemittierende Folien den Effekt, den Emissionsgrad im Wellenlän- genbereich von 3 pm bis 50 gm, insbesondere im Bereich des Maximums der Wärmestrah- lung bei Raumtemperatur (etwa 10 pm) abzusenken. Dadurch wirken sie als gute Reflek- toren für Wärmestrahlung bei Raumtemperatur und können in Hohlkammerprofilen wirksam zur Verbesserung der Wärmedämmung eingesetzt werden. In derartigen niedrigemittieren- den Beschichtungen und niedrigemittierenden Folien dienen Metallschichten, beispielswei- se Aluminium-, Silber-, Gold-, und/oder Kupferschichten zur Erzeugung der hohen Reflexi- on im infraroten Spektralbereich. Die Metallschichten können eine Dicke im Bereich von 5 nm bis 200 pm, vorzugsweise im Bereich von 10 nm bis 25 nm aufweisen. Ebenso können Schichten, die entsprechende Metalloxide mit entsprechender Dicke enthalten, zum Einsatz kommen. Diese emissionsverringernden Schichten sind bevorzugt mit einer Schutzschicht (insbesondere mit antioxidativer Wirkung), einer Dekorschicht, einer Farbschicht, einer Lackschicht, einer Funktionsschicht (beispielsweise einer Schicht mit geringer Oberflä- chenspannung, z.B. easy-to-clean) sowie Kombinationen der genannten Schichten in einer oder mehreren Schichten überzogen sein. Dabei hat es sich als günstig erwiesen, wenn die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie in einem Winkel zur Wärmedurchgangsrichtung des erfindungsgemäßen Hohlkammerprofils im Verwen- dungszustand, d. h. in dem in eine Wand eines Gebäudes eingebauten Zustand eines Fensters oder einer Tür, in der ein Profilabschnitt des erfindungsgemäßen Hohlkammerpro- fils eingesetzt ist, angeordnet ist, der im Bereich von 70° bis 110°, vorzugsweise 80° bis 100° liegt und besonders bevorzugt nahe 90° liegt. Die Wärmedurchgangsrichtung durch das erfindungsgemäße Hohlkammerprofil verläuft dabei von der raumseitigen Außenwand zur wetterseitigen Außenwand. Dabei kann es sich auch als geeignet heraussteilen, wenn das erfindungsgemäße Hohlkammerprofil eine Haupthohlkammer aufweist, deren Innen- wände zumindest teilweise mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen werden. Die Haupthohlkammer eines Hohlkammerpro- fils, bei der es sich üblicherweise um eine Armierungskammer handelt, in die eine Armie- rung für das Profil, meist eine Stahlarmierung, aufgenommen werden kann, ist die Hohl- kammer des Profils, in denen die Wände am weitesten voneinander beabstandet sind. Da- her ist der Effekt der Wärmestrahlung in diesen Kammern am stärksten, wodurch wiede- rum der durch die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie erzielte Effekt hoch ist. Dabei ist es besonders bevorzugt, wenn zwei einander gegenüber- liegende Innenwände der Haupthohlkammer, insbesondere die Innenwand an der Seite der raumseitigen Außenwand und die Innenwand an der Seite der wetterseitigen Außenwand, zumindest teilweise mit einer niedrigemittierenden Beschichtung und/oder einer niedrig emittierenden Folie versehen sind. Bei einer derartigen Anordnung sind die niedrigemittie- rende Beschichtung und/oder die niedrigemittierende Folie in etwa senkrecht zur Wärme- durchgangsrichtung des erfindungsgemäßen Hohlkammerprofils im Verwendungszustand angeordnet, so dass der durch die niedrigemittierende Beschichtung und/oder die niedrig emittierende Folie erzielte reflektierende Effekt hoch ist. In diesem Zusammenhang kann es auch von Vorteil sein, wenn ein Teilprofil als im Profil querschnitt geschlossenes Hohlkammerprofil ausgebildet ist, in das das andere Teilprofil, das mindestens eine einseitig offene Hohlkammer aufweist, wobei mindestens eine der Innenwände der einseitig offenen Hohlkammer mit der niedrigemittierenden Beschichtung und/oder der niedrigemittierenden Folie versehen ist, eingeschoben wird. Dies liefert einen leicht variierbaren Aufbau des erfindungsgemäßen Hohlkammerprofils. In this context, it may also be useful if the method prior to step (b) further comprises the step of applying a low-emissivity coating and / or a low-emissivity film to at least one of the outer walls and / or inner walls surrounding the hollow cavities open on one side comprises, wherein the hollow chamber open on one side by the joining of the sub-profiles in step (b) is closed. As a result, the heat transfer can be significantly reduced by an inventive hollow chamber profile. Low-emissivity coatings (also referred to as "low-e coatings") and low-emittance films (also referred to as "low-e films") have a high degree of reflection and are associated with high transmission in the visible part of the electromagnetic spectrum in the infrared spectral range a low emissivity (low emissivity). Accordingly, low-emissivity coatings and low-emittance films have the effect of lowering the emissivity in the wavelength range of 3 pm to 50 gm, in particular in the region of the maximum heat radiation at room temperature (about 10 pm). As a result, they act as good reflectors for thermal radiation at room temperature and can be used effectively in hollow chamber profiles to improve thermal insulation. In such low-emissivity coatings and low-etch films, metal layers, such as aluminum, silver, gold, and / or copper layers, are used to produce the high reflectivity coatings. on in the infrared spectral range. The metal layers may have a thickness in the range of 5 nm to 200 μm, preferably in the range of 10 nm to 25 nm. Likewise, layers containing corresponding metal oxides of appropriate thickness can be used. These emission-reducing layers are preferably provided with a protective layer (in particular with an antioxidative effect), a decorative layer, a color layer, a lacquer layer, a functional layer (for example a layer with a low surface tension, eg easy-to-clean) and combinations of the layers mentioned in one or more layers. It has proven to be advantageous if the low-emitting coating and / or the low-emitting film at an angle to the heat transfer direction of the hollow chamber profile according to the invention in the used state, ie in the built-in a wall of a building state of a window or a door in the Profile section of the invention Hohlkammerpro- fils is used, is arranged, which is in the range of 70 ° to 110 °, preferably 80 ° to 100 °, and is particularly preferably close to 90 °. The heat transfer direction through the hollow chamber profile according to the invention extends from the room-side outer wall to the weather-side outer wall. It may also prove to be suitable if the hollow chamber profile according to the invention has a main hollow chamber whose inner walls are at least partially provided with a low-emitting coating and / or a low-emitting film. The main hollow chamber of a hollow chamber profile, which is usually a reinforcing chamber, into which a reinforcement for the profile, usually a steel reinforcement, can be accommodated, is the hollow chamber of the profile in which the walls are furthest apart are spaced. Therefore, the effect of heat radiation is strongest in these chambers, whereby, in turn, the effect achieved by the low-emissivity coating and / or the low-emissivity film is high. It is particularly preferred if two opposing inner walls of the main hollow chamber, in particular the inner wall on the side of the room-side outer wall and the inner wall on the side of the weather-side outer wall, at least partially provided with a low-emitting coating and / or a low-emitting film , With such an arrangement, the low-emissivity coating and / or the low-emissivity film are disposed approximately perpendicular to the heat-transmitting direction of the hollow chamber profile of the invention in the use state, so that the reflective effect achieved by the low-emissivity coating and / or low-emissivity film is high. In this context, it may also be advantageous if a partial profile is formed as a profile cross-section closed hollow chamber profile in which the other part profile having at least one hollow chamber open on one side, wherein at least one of the inner walls of the one-sided open hollow chamber with the low-emitting coating and / or the low-emitting film is inserted is inserted. This provides a slightly variable structure of the hollow chamber profile according to the invention.
Ein Beispiel für eine geeignete niedrigemittierende Beschichtung und/oder eine niedrigemit- tierende Folie, die in dem Verfahren und dem Hohlkammerprofil gemäß der vorliegenden Erfindung eingesetzt werden kann, ist in der DE 10 2005 025 982 B4 beschrieben, auf die hinsichtlich des Aufbaus, der Materialien und der Herstellung von niedrigemittierenden Be- schichtungen und/oder niedrigemittierenden Folien hiermit explizit Bezug genommen wird. Exemplarisch kann gemäß der vorliegenden Erfindung als niedrigemittierende Folie eine low-e-Kunststofffolie (PET) vom Typ Heat Mirror® HM 55 der Firma Southgate Europe GmbH eingesetzt werden. Eine niedrigemittierende Beschichtung kann auch in Form eines Lacks auf die Innenwände und/oder die Außenwände des Hohlkammerprofils aufgebracht worden sein. An example of a suitable low-emissivity coating and / or low-modifying film which can be used in the method and the hollow chamber profile according to the present invention is described in DE 10 2005 025 982 B4, with regard to structure, materials and the manufacture of low-emissivity coatings and / or low-etch films are hereby incorporated by reference. By way of example, according to the present invention, a low-e-plastic film (PET) of the type Heat Mirror® HM 55 from Southgate Europe GmbH can be used as the low-emittance film. A low-emissivity coating may also have been applied in the form of a lacquer to the inner walls and / or the outer walls of the hollow chamber profile.
Zusätzlich oder alternativ dazu kann es auch günstig sein, wenn das Verfahren vor Stufe (b) weiter die Stufe des Einbringens eines Isolierungsmaterials, insbesondere eines ther- misch isolierenden Schaumstoffs, in mindestens eine einseitig offene Hohlkammer des Teilprofils umfasst, die durch das Verbinden der Teilprofile in Stufe (b) geschlossen wird. Isolierungsmaterial stellt ein weiteres Beispiel für ein Funktionselement dar, das sich nach dem Herstellen eines einstückigen Hohlkammerprofils nicht mehr ganz einfach und gleich- mäßig in die Hohlkammern des Profils einbringen lässt. Additionally or alternatively, it may also be favorable if the method before stage (b) further comprises the step of introducing an insulating material, in particular a thermally insulating foam, into at least one hollow chamber of the partial profile which is open on one side, by connecting the partial profiles in step (b) is closed. Insulation material represents a further example of a functional element which, after producing a one-piece hollow chamber profile, can no longer be easily and uniformly introduced into the hollow chambers of the profile.
Ebenso kann es von Nutzen sein, wenn eine wetterseitige Außenwand des erfindungsge- mäßen Hohlkammerprofils mit einer die Wetterfestigkeit verbessernden Schicht versehen ist. Dadurch wird die Langlebigkeit des erfindungsgemäßen Hohlkammerprofils erhöht. Da- zu kann beispielsweise ein UV-beständiger Lack, insbesondere auf Acryl- oder Silikonba- sis, in einer Schichtdicke von etwa 1 ,5 pm bis etwa 25 pm, bevorzugt in einer Schichtdicke von etwa 2 pm bis etwa 5 pm, auf die Deckschale aufgebracht werden. Ein derartiger Lack ist beispielsweise das Lacksystem NE0712 der neoxid GmbH. Bevorzugt kann es auch sein, dass raumseitige Außenwand und/oder die wetterseitige Au- ßenwand des erfindungsgemäßen Hohlkammerprofils, besonders bevorzugt sowohl die raumseitige Außenwand als auch die wetterseitige Außenwand des erfindungsgemäßen Hohlkammerprofils, ein Material mit einer Oberflächenspannung von höchstens 20 mN/m umfasst. Auf diese Weise werden die Außenoberflächen des erfindungsgemäßen Hohl- kammerprofils schmutzabweisend und sind leicht zu reinigen. Als derartige Material haben sich insbesondere Polytrifluorchlorethylen (PTFCE) und Polytetrafluorethylen (PTFE) er- wiesen. It may also be useful if a weather-side outer wall of the hollow chamber profile according to the invention is provided with a layer improving the weather resistance. As a result, the longevity of the hollow chamber profile according to the invention is increased. For example, a UV-resistant lacquer, in particular on acrylic or Silikonba- sis, in a layer thickness of about 1, 5 pm to about 25 pm, preferably in a layer thickness of about 2 pm to about 5 pm, on the cover shell be applied. Such a paint, for example, the paint system NE0712 neoxid GmbH. It may also be preferred that the room-side outer wall and / or the weather-side outer wall of the hollow chamber profile according to the invention, particularly preferably both the room-side outer wall and the weather-side outer wall of the hollow chamber profile according to the invention, comprises a material having a surface tension of at most 20 mN / m. In this way, the outer surfaces of the hollow chamber profile according to the invention become dirt-repellent and are easy to clean. In particular, polytrifluorochloroethylene (PTFCE) and polytetrafluoroethylene (PTFE) have proven to be such materials.
In bevorzugten Ausführungsformen des erfindungsgemäßen Verfahrens ist in eine Hohl- kammer eines Teilprofils eine Stahlarmierung aufgenommen, die mit einer der Innenwände und/oder der Außenwände des Teilprofils stoffschlüssig verbunden, insbesondere verklebt, ist. In preferred embodiments of the method according to the invention, a steel reinforcement is accommodated in a hollow chamber of a partial profile, which is connected to one of the inner walls and / or the outer walls of the partial profile in a materially bonded, in particular glued, manner.
Es kann auch von Nutzen sein, wenn mindestens eines der Teilprofile Vorsprünge aufweist, über die in Stufe (b) das Verbinden mit dem anderen Teilprofil erfolgt, das entsprechende Aufnahmebereiche umfasst. Auf die Vorsprünge eines Teilprofils lässt sich beispielsweise ein entsprechender Klebstoff aufbringen, der dann mit einem zugeordneten Aufnahmebe- reich des anderen Teilprofils verklebt werden kann. Beim Verschmelzen können bevorzugt die Vorsprünge des einen Teilprofils aufgeschmolzen werden und mit einem zugeordneten Aufnahmebereich des anderen Teilprofils verschmelzen. Dadurch wird eine saubere und zuverlässige Verbindung zwischen den Teilprofilen gewährleistet. It may also be useful if at least one of the sub-profiles has projections over which in step (b) the connection to the other sub-profile takes place, which comprises corresponding receiving areas. For example, a corresponding adhesive can be applied to the projections of a partial profile, which can then be adhesively bonded to an associated receiving region of the other partial profile. During fusing, the projections of one partial profile can preferably be melted and fuse with an associated receiving region of the other partial profile. This ensures a clean and reliable connection between the sub-profiles.
Die erfindungsgemäß hergestellten Hohlkammerprofile werden bevorzugt zur Herstellung einer Rahmenbaugruppe eines Kunststoff-Fensters oder einer Kunststoff-Tür verwendet. Durch Verschweißen von auf Gehrung geschnittenen Stücken eines erfindungsgemäßen Hohlkammerprofils kann ein Fenster- oder Türrahmen erhalten werden. Der erhaltene Fenster- oder Türrahmen ist für den Einbau in eine Öffnung einer Wandung eines Gebäu- des vorgesehen bzw. in die Öffnung der Wandung eines Gebäudes einbaubar. The hollow chamber profiles produced according to the invention are preferably used for producing a frame assembly of a plastic window or a plastic door. By welding mitred pieces of a hollow chamber profile according to the invention, a window or door frame can be obtained. The resulting window or door frame is intended for installation in an opening in a wall of a building or can be installed in the opening of the wall of a building.
Das erfindungsgemäße Hohlkammerprofil sowie einzelne Teile davon können auch zeilen- weise oder schichtweise unter Verwendung eines zeilenaufbauenden oder schichtaufbau- enden Fertigungsverfahrens (z. B. 3D-Druck) hergestellt werden, bevorzugt ist jedoch die Herstellung mittels Extrusion oder Coextrusion. Im Folgenden soll die vorliegende Erfindung unter Bezugnahme auf die in den Figuren dar- gestellten Ausführungsformen im Detail erläutert werden. Dabei zeigen The hollow chamber profile according to the invention as well as individual parts thereof can also be produced line by line or layer by layer using a line-building or layer-building manufacturing process (eg 3D printing), however preference is given to production by means of extrusion or coextrusion.
