Abstract

The thermal insulated building profile is made from Polyurethane (PUR) having internal reinforcement. The reinforcement is made of fiber-reinforced plastic with small heat conductivity. The strengthened plastic is a polyester resin, an Epoxy or a PU resin. An independent claim is included for a building profile.

Description

Bauprofile aus Polyurethan-Integralhartschaumstoff (PUR), wie sie z.B. in den Deutschen Patenten Nr. 34 08 995 und 34 08 975 beschrieben werden, benötigen zur Erlangung einer ausreichenden Steifigkeit Kernprofile aus Metall, i.A. Aluminium Hohlprofile, welche entweder 1-stückig als 4-kant-Rohrprofile mit angeformten Schenkeln ausgebildet sind oder zur Erlangung besserer Wärme-Dämmwerte in einer Weiterentwicklung 2-stückig in Form von räumlich getrennten Einzelprofilen wie sie im Gebrauchsmuster Nr. 201 05 8758 beschrieben sind.Structural profiles made of polyurethane integral rigid foam (PUR), as described, for example, in German Pat. 34 08 995 and 34 08 975 To obtain a sufficient rigidity core profiles of metal, iA aluminum hollow sections, which are either 1-piece formed as a 4-edge pipe profiles with molded legs or to obtain better thermal insulation values in a development 2-piece in the form of spatially Separate individual profiles as described in utility model no. 201 05 8758 are described.

Die Zeichnungsquerschnitte auf Fig. 1-2 zeigen Profile dieser Art, bestehend aus Blendrahmen, Flügelprofil mit Isolierglas und Glasleiste.The drawing cross sections on Fig. 1-2 show profiles of this type, consisting of frame, sash profile with insulating glass and glazing bead.

Die Wärmedämmung dieser Profile, ausgedrückt durch den sog. U-Wert, wird im Wesentlichen bestimmt durch die Dicke "d" der PUR-Ummantelung bzw. durch die Gesamtdicke des PUR-Materials in horizontaler Richtung bestehend aus Ummantelung und Abstand der Metallschalen d = d1 + d2 + d3.The thermal insulation of these profiles, expressed by the so-called U-value, is essentially determined by the thickness "d" of the PUR coating or by the total thickness of the PUR material in the horizontal direction consisting of sheathing and distance of the metal shells d = d 1 + d 2 + d 3 .

Grund hierfür ist der im Vergleich zum Metallkern sehr hohe Wärmeleitwiderstand des PUR-Materials, bestimmt durch die sog. Wärmeleitzahl Lambda λ. Diese beträgt
150,0 W/mK bei Aluminium
0,085 bei PUR mit einer Dichte von 600 kg/m3
0,040 bei PUR mit einer Dichte von 200 kg/m3.The reason for this is the very high thermal resistance of the PUR material compared to the metal core, determined by the so-called thermal conductivity lambda λ. This is
150.0 W / mK for aluminum
0.085 for PUR with a density of 600 kg / m 3
0.040 for PUR with a density of 200 kg / m 3 .

Es ist zu erkennen, dass Aluminium die Wärme unvergleichlich besser leitet als PUR, insbesondere bei geringer PUR-Dichte.It can be seen that aluminum conducts the heat incomparably better than PUR, especially with low PUR density.

Hieraus ergeben sich U-Werte von ca. 1,8 W/m2K bei Profiltyp gem. Fig. 1 1,2 W/m2K bei Profiltyp gem. Fig. 2 This results in U-values of about 1.8 W / m 2 K at profile type acc. Fig. 1 1 . 2 W / m 2 K for profile type acc. Fig. 2

Der letztgenannte Wert ist für Standard-Fenster derzeit ein sehr guter Wert; er liegt im Bereich hochwertiger 2-Scheiben-lsolierverglasung; jedoch werden zunehmend bessere Dämmwerte von deutlich unter 1,0 W/m2K gewünscht, die beim Isolierglas z.B. durch Verwendung von 3-Scheiben-Glas mit einem Ug-Wert von 0,5 bis 0,7 möglich sind, jedoch im Rahmenbereich nur durch Einsatz aufwändiger, teilweise passivhaus-tauglicher Rahmen.The latter value is currently a very good value for standard windows; it is in the range of high-quality 2-pane insulating glass; However, increasingly better insulating values of well below 1.0 W / m 2 K are desired, which are possible with insulating glass, for example, by using 3-pane glass with a Ug value of 0.5 to 0.7, but in the frame only by Use of elaborate, partially passive house-suitable frame.

Bei einer Weiterentwicklung des Profiltyps gem. Fig. 2 kann der Abstand zwischen den beiden Metall-Schalen durch Einsatz von Verstärkungsgewebe (Gebrauchsmuster Nr. 203 13 884.8 ) deutlich erhöht und damit ein besserer U-Wert erzielt werden, jedoch geht dies zu Lasten der Profilbreite, welche aus verschiedenen Gründen möglichst gering gewünscht wirdIn a further development of the profile type gem. Fig. 2 the distance between the two metal shells can be increased by using reinforcement fabric (utility model no. 203 13 884.8 ) is significantly increased and thus a better U-value can be achieved, but this is at the expense of the profile width, which is desired as low as possible for various reasons

Der gewünschte Dämmwert von deutlich unter 1,0 W/m2K wird bei geringer, d.h. unveränderter Profilbreite erfindungsgemäß nun dadurch erreicht, dass anstelle von Metallverstärkungen solche aus faserverstärkten Kunststoffprofilen mit einer wesentlich niedrigeren Wärmeleitzahl eingesetzt werden.The desired insulation value of well below 1.0 W / m 2 K is achieved according to the invention at low, ie unchanged profile width, that are used instead of metal reinforcements made of fiber-reinforced plastic profiles with a much lower thermal conductivity.

Fig. 3 zeigt diese Querschnitte beispielhaft. Fig. 3 shows these cross sections by way of example.

Derartige GfK-Profile (GfK = glasfaserverstärkter Kunststoff) zeichnen sich aus durch

  • sehr hohe Festigkeit
  • extrem geringe thermische Längenausdehnung; der thermische Längen-Ausdehnungskoeffizient liegt um den Faktor 3-4 unter dem von Aluminium
  • geringes Gewicht
  • gute Verbindung zum Umgebungsmaterial PUR und ganz besonders
  • niedrigen Lambda - Wert von 0,2-0,4 W/mK
Such GfK profiles (GfK = glass fiber reinforced plastic) are characterized by
  • very high strength
  • extremely low thermal expansion; the coefficient of thermal expansion is 3-4 times lower than that of aluminum
  • low weight
  • good connection to the surrounding material PUR and very special
  • low lambda value of 0.2-0.4 W / mK

Die Wärmeleitzahl ist damit etwa um den Faktor 500 besser als die von Aluminium; sie liegt fast im Bereich des umgebenden PUR-Materials und das Tragprofil ist demnach keine "Wärmebrücke" mehr. Letzteres umso mehr, als die Dicke des Profils wegen der hohen Festigkeit sehr gering gehalten werden kann. Hierdurch kommt als Damm-Breite "d" praktisch die gesamte Profilstärke zur Wirkung.The thermal conductivity is about 500 times better than that of aluminum; It is almost in the area of the surrounding PUR material and the support profile is therefore no longer a "thermal bridge". The latter all the more, because the thickness of the profile can be kept very low because of the high strength. As a result, as the dam width "d" practically the entire profile strength comes into effect.

Die Herstellung solcher GfK-Profile erfolgt kontinuierlich im sog. Pultrusions-Verfahren. Dies erlaubt einen hohen Faser-Anteil von bis zu 80 %; Faserart und -anteil, Harztyp und Geometrie können je nach Bedarf in einem breiten Spektrum gewählt werden. Bei Massen-Anwendungen werden meistens Polyester-Harz und Glasfasern als Strang-Bündel verwendet. Möglich sind auch Epoxy-Harze und Kohlenstoff-Fasern (Carbon) oder Fasern aus nachwachsenden Rohstoffen.The production of such GfK profiles is carried out continuously in the so-called pultrusion process. This allows a high fiber content of up to 80%; Fiber type and proportion, resin type and geometry can be as needed in be chosen in a broad spectrum. In mass applications polyester resin and glass fibers are mostly used as strand bundles. Also possible are epoxy resins and carbon fibers (carbon) or fibers from renewable raw materials.

Diese Kombination ermöglicht Herstellungskosten unterhalb der eingangs beschriebenen Alu-Profile. Die Festigkeit ist mindestens gleichwertig; Das GfK-Profil kann sowohl als Hohlprofil mit angeformten Stegen wie als offenes, einstückiges Profil gestaltet werden; ebenso kann es 2-teilig und durch Stege oder Abstandshalter in der gewünschten Position fixiert sein.This combination allows manufacturing costs below the aluminum profiles described above. The strength is at least equivalent; The GfK profile can be designed both as a hollow profile with integrally formed webs and as an open, one-piece profile; it may also be 2-piece and fixed by webs or spacers in the desired position.

Die Herstellung solcher PUR-Profile erfolgt in gleicher Weise wie jene mit Alu-Kern, d.h. durch Umschäumen des Kern-Profils in im Allgemeinen 2-teiligen Schäumformen im sog. RSG-Verfahren = Reaktion-Spritzguß. Die beim Befüllen des Werkzeuges gemischten, gut fließfähigen PUR-Komponenten umströmen das vor dem Schließen der Form eingelegte Kernprofil und härten während der sog. Formstandzeit von einigen Minuten zu einem praktisch unlösbaren Verbund mit dem Verstärkungsprofil aus.The production of such PUR profiles is carried out in the same way as those with aluminum core, ie by foaming the core profile in generally 2-part foam molds in the so-called RSG process = reaction injection molding. The well-flowable PU components mixed during filling of the tool flow around the core profile inserted before closing the mold and harden during the so-called mold life of a few minutes to a virtually insoluble bond with the reinforcing profile.

Nach der Entnahme aus der Form ist das PUR-Profil sofort verarbeitungsbereit. In einer Sonderform dieses RSG-Verfahrens kann auch das sog. Formlackier-Verfahren (in-mold-coating = IMC) eingesetzt werden, bei dem vor dem Einlegen des Verstärkungsprofils ein geeigneter lack in die offene Form gesprüht wird, der sich bei der Reaktion des PUR-Materials mit diesem verbindet und ein grundiertes oder fertig lackiertes Formteil ergibt.After removal from the mold, the PUR profile is ready for use immediately. In a special form of this RSG process, the so-called. In-mold-coating (IMC) can be used, in which a suitable lacquer is sprayed into the open mold before inserting the reinforcing profile, which in the reaction of PUR material connects with this and gives a primed or finished painted part.

Die Verarbeitung der Profile zu im allgemeinen Rahmen erfolgt durch Ablängen der Profile auf das gewünschte Maß und durch Zusammenfügen an den Ecken unter Einsatz von Eckwinkeln oder mittels Schrauben mit Kleber.The processing of the profiles in the general framework is carried out by cutting the profiles to the desired size and by joining together at the corners using corner brackets or screws with adhesive.

Fig. 3 zeigt ein solches GfK-Profil beispielhaft als Verstärkung in dem eingangs beschriebenen PUR-Profil. Fig. 3 shows such a GfK profile example as reinforcement in the PUR profile described above.
