Independent claims are also included for: (a) heat insulating windows or doors with frames consisting of the proposed extrusion profile; (b) a method for producing the proposed extrusion profile.

Description

Die Erfindung betrifft ein Extrusionsprofil mit Hohlräumen, die ganz oder teilweise mit einem Partikelschaum aus einem thermoplastischen Polymer gefüllt sind, Verfahren zur Herstellung sowie die Verwendung als Rahmen für wärmedämmende Fenster oder Türen.The invention relates to an extrusion profile with cavities which are completely or partially filled with a particle foam made of a thermoplastic polymer, a method for producing and the use as a frame for heat-insulating windows or doors.

Für den Einsatz im Passivhaus müssen die Fenster neben gutdämmenden Verglasungen auch Rahmen mit entsprechenden Eigenschaften aufweisen. Weit verbreitet ist dabei das Ausschäumen der Hohlkammern mit PUR—Schaumstoff oder Füllen mit Einschieblingen ( Erfolgreich Energie sparen, Kunststoffe 1 (2003), Seiten 76 - 79, Carl Hanser Verlag Münch en). Die Einschieblinge müssen der Form der Hohlkammern angepasst sein und stellen einen aufwändigen Arbeitsschritt bei der Herstellung der Fensterrahmen dar.For use in a passive house, the windows must have well-insulating glazing as well as frames with corresponding properties. The foaming of the hollow chambers with PUR foam or filling with inserts ( Successfully saving energy, Kunststoffe 1 (2003), pages 76 - 79, Carl Hanser Verlag Münch s). The Einschieblinge must be adapted to the shape of the hollow chambers and represent a complex step in the production of window frames.

Die DE-A 195 04 601 beschreibt ein wärmedämmendes Verbundprofil zur Herstellung von Fenster- oder Türrahmen aus zwei im Abstand voneinander angeordneten Metallprofilen, die durch Isolierstege miteinander Verbunden sind. Zur Wärmedämmung wird in die Kammern ein Wärmedämmmaterial eingebracht, das in komprimiertem Zustand in einer Umhüllung eingeschlossen ist und das sich bei Wärmeeinwirkung dehnt oder reißt.The DE-A 195 04 601 describes a heat-insulating composite profile for the production of window or door frames of two spaced-apart metal profiles which are interconnected by insulating bars. For thermal insulation, a thermal insulation material is introduced into the chambers, which is enclosed in a wrapped state in a sheath and which expands or breaks when exposed to heat.

Ein wiederaufarbeitbares Stoßfängersystem aus Vollkunststoff mit einem energieabsorbierenden Polypropylenschaumkern und einer kautschukmodifizierten Polypropylenhülle ist aus EP-B 425 923 bekannt. Hierbei wird zunächst der Schaumkern durch Verpressen oder Verschweißen von Schaumpartikeln in einer Form hergestellt und anschließend durch Verschweißen oder Verschrauben mit der Hülle und einem Stoßfängerträger verbunden.A refurbable full plastic bumper system with an energy absorbing polypropylene foam core and a rubber modified polypropylene shell is made EP-B 425 923 known. Here, the foam core is first prepared by pressing or welding foam particles in a mold and then connected by welding or screwing with the shell and a bumper beam.

EP-A-0 967 356 beschreibt ein Hohlprofil wie im Oberbegriff des Anspruchs 1 mit einem Isoliermittel aus geschäumten Polypropylen. EP-A-0 967 356 describes a hollow profile as in the preamble of claim 1 with an insulating agent of foamed polypropylene.

Aufgabe der vorliegenden Erfindung war es, wärmedämmende Extrusionsprofile bereitzustellen, die auch bei mehreren Hohlkammern oder komplizierten Formen einfach herstellbar sind und sich insbesondere für Fenster- und Türrahmen für Passivhäuser eignen.Object of the present invention was to provide heat-insulating extrusion profiles that are easy to produce even with multiple hollow chambers or complicated shapes and are particularly suitable for window and door frames for passive houses.

Demgemäss wurde das eingangs beschriebene Extrusionsprofil gefunden. Sie eignen sich insbesondere zur Herstellung von wärmedämmenden Fenstern- oder Türrahmen. Neben der Wärmedämmung kann der Partikelschaum noch die Schalldämmung und Schwingungsdämpfung des Extrusionsprofils verbessern. Sie können ein oder mehrere Hohlräume oder Kammern aufweisen, die ganz oder teilweise mit dem Partikelschaum gefüllt sind.Accordingly, the extrusion profile described above was found. They are particularly suitable for the production of heat-insulating window or door frames. In addition to thermal insulation, the particle foam can still improve the sound insulation and vibration damping of the extrusion profile. You may have one or more cavities or chambers that are completely or partially filled with the particle foam.

Das Extrusionsprofil besteht aus Polypropylen.The extrusion profile consists of Polypropylene.

Als Partikelschaum zur Füllung der Hohlräume werden Partikelschäume aus thermoplastischen Polymeren wie im Anspruch 1 angegeben verwendet. Die Partikelschäume können durch Expansion von expandierbaren Thermoplasten, Imprägnierverfahren, wie expandiertes Polypropylen (EPP) oder durch Extrusion von treibmittelhaltigen Polymerschmelzen zu Schaumsträngen erhalten werden und gegebenenfalls vor dem einfüllen noch nachgeschäumt werden können. In der Regel verwendet man zum Füllen Partikelschäume, die einen mittleren Durchmesser im Bereich von 1 bis 10 mm, bevorzugt im Bereich von 2 bis 8 mm und eine Dichte im Bereich von 20 bis 150 g/l, bevorzugt im Bereich von 50 bis 120 g/l auf. Bevorzugt verwendet man einen - Partikelschaum aus Homopolypropylen oder einem Copolymeren mit 0,5 bis 15 Gew.-% Ethen und/oder Buten-1 und einem Kristallitschmelzpunkt im Bereich von 120 bis 170°C.Particle foams of thermoplastic polymers as stated in claim 1 are used as particle foam for filling the cavities. The particle foams can be obtained by expansion of expandable thermoplastics, impregnation processes, such as expanded polypropylene (EPP) or by extrusion of propellant-containing polymer melts into foam strands and, if appropriate, can be re-foamed before filling. As a rule, foaming is carried out using particle foams having an average diameter in the range from 1 to 10 mm, preferably in the range from 2 to 8 mm, and a density in the range from 20 to 150 g / l, preferably in the range from 50 to 120 g / l on. Preference is given to using a particle foam made from homopolypropylene or a copolymer having from 0.5 to 15% by weight of ethene and / or butene-1 and a crystallite melting point in the range from 120 to 170.degree.

Zur Herstellung von Rahmen für wärmegedämmte Kunststofffenster für Passivhäuser werden Extrusionsprofile aus Polypropylen verwendet, deren Hohlräume mit einem expandierten Polypropylen-Partikelschaum (EPP) gefüllt sind. Da sowohl das Fensterprofil wie auch die Wärmedämmung aus dem gleichen Grundstoffen hergestellt und halogenfrei sind, sind sie einfach recyclierbar. Besonders bevorzugt werden Kunststofffenster-Systeme aus coextrudieren Polypropylen-Profilen mit 2 oder 3 Kammern.For the production of frames for heat-insulated plastic windows for passive houses extrusion polypropylene profiles are used, whose cavities are filled with an expanded polypropylene particle foam (EPP). Since both the window profile and the thermal insulation are made from the same basic materials and are halogen-free, they are easily recyclable. Particularly preferred are plastic window systems of coextruded polypropylene profiles with 2 or 3 chambers.

Zur Herstellung von wärmegedämmten Extrusionsprofile kann man, einen Partikelschaum aus einem thermoplastischen Polymer in eine oder mehrere Kammern eines Extrusionsprofils füllen, komprimieren und anschließend die Enden des Extrusionsprofils verschließen. Zum Füllen des Extrusionsprofils verschließt man zweckmäßigerweise ein Ende mit einem feinmaschigen Sieb und füllt und komprimiert den Partikelschaum mit Luft in das Extrusionsprofil. Die Maschenweite des Siebes richtet sich nach der Partikelgröße des Partikelschaums und dem gewünschten Druck beim Füllen und komprimieren. Um die Partikel in den Hohlräumen zu fixieren, können diese nach dem Einfüllen mit Heißluft oder Wasserdampf behandelt werden. Bei dieser Behandlung versintern die Partikel zu einem Schaumblock in Form des Hohlkammerprofils.To produce heat-insulated extrusion profiles, one can fill a particle foam made of a thermoplastic polymer in one or more chambers of an extrusion profile, compress and then close the ends of the extrusion profile. To fill the extrusion profile, it is expedient to close one end with a fine-mesh sieve and to fill and compress the particle foam with air into the extrusion profile. The mesh size of the screen depends on the particle size of the particle foam and the desired pressure during filling and compression. To fix the particles in the cavities, they can be treated after filling with hot air or steam. In this treatment, the particles sinter into a foam block in the form of the hollow chamber profile.
