Description

Wärmedämmender Abstandhalter für IsolierverglasungenInsulating spacer for double glazing
Die Erfindung betrifft ein Verfahren und ein Dichtungspro- fil zur Einglasung von Isolierglasscheiben bei der Mehrfachverglasung in Profilsystemen (Rahmenkonstruktionen) für den Fenster- und Fassadenbau.The invention relates to a method and a sealing profile for glazing insulating glass panes for multiple glazing in profile systems (frame structures) for window and facade construction.
Die progressive Steigerung der Anforderungen an die Wärmedämmung im Fenster- und Fassadenbau in den zurückliegenden Jahren haben eine Vielzahl konstruktiv und materialtechnisch begründeter Maßnahmen eingeleitet, die in summarischer Wirkung zum Ziele hatten, die geforderten k-Werte zu unterschreiten .The progressive increase in the requirements for thermal insulation in window and facade construction in the past years has initiated a variety of constructive and material-related measures, which had the overall aim of falling below the required k-values.
So werden z. B. auch die Vorzüge des Werkstoffes Aluminium für die Verwendung im Fenster- und Fassadenbau mittlerweile sehr differenziert gewertet, da seine Wärmeleitfähigkeit von ca. 200 W/(m * K) gegenüber Holz und Kunststoff (kleiner 1 W/(m * K) z. B. (EPDM 0,4 W/(m * K)) doch erheblich ist.So z. B. the advantages of the material aluminum for use in window and facade construction meanwhile very differently evaluated, since its thermal conductivity of approx. 200 W / (m * K) compared to wood and plastic (less than 1 W / (m * K) z B. (EPDM 0.4 W / (m * K)) is considerable.
Für Aluminium-Fenster bedeutet dies, daß Wärme- bzw. Kälteströme über die Stege und Wandungen von innen nach außen bzw. umgekehrt transportiert werden. D. h. , das Profil bildet praktisch eine Wärmebrücke über die bei genügend hoher Temperaturdifferenz zwischen den Enden ein stetiger Wärmeabstrom erfolgt. Derartige Verlustwärmen sind je nach Temperaturdifferenz, Material und Leitquerschnitt, erheblich und teuer. Alles konstruktive Bemühen konzentrierte sich daher auf die Entwicklung, diese unerwünschten Wärmebrücken, die durch das Profil entstehen, zu unterbinden. Dies führte zu hochentwickelten Profilkonstruktionen, wie beispielsweise die Isolierstegkonstruktionen, wie man sie vom Einsatz in Gebäuden mit Klimaanlagen kennt. Heute sind die Anforderungen an die Wärmedämmung präzisiert und für die einzelnen Bauteile definiert. Für Fensterrahmen entstanden die "Rahmenmaterialgruppen für Fenster", die Material und Konstruktionsaufbau der Rahmen bewerten.For aluminum windows, this means that heat or cold flows through the webs and walls from the inside to the outside be transported outside or vice versa. That is, , the profile practically forms a thermal bridge over which there is a constant heat dissipation if the temperature difference between the ends is sufficiently high. Such heat losses are considerable and expensive, depending on the temperature difference, material and guide cross-section. All constructive efforts therefore concentrated on the development to prevent these undesirable thermal bridges, which are created by the profile. This led to highly developed profile constructions, such as the isolating bridge constructions known from use in buildings with air conditioning systems. Today, the requirements for thermal insulation are specified and defined for the individual components. The "frame material groups for windows" were created for window frames, which evaluate the material and construction of the frame.
Wesentlich ist bei fast allen Konstruktionen das Prinzip der thermischen Trennung. Bei Metallprofilen ist es logisch und zwingend.The principle of thermal separation is essential in almost all constructions. It is logical and imperative for metal profiles.
Von innen nach außen durchgehende Profile werden danach in zwei Teilprofile getrennt, und diese werden durch ein Material mit sehr schlechter Wärmeleitfähigkeit wieder miteinander verbunden. Die Entwicklung ist jedoch noch lange nicht abgeschlossen, da mit immer neuen Erfindungen und Innovationen das mechanische und wärmetechnische Verhalten thermisch getrennter Profilsysteme aufeinander abgestimmt wird.Continuous profiles from the inside to the outside are then separated into two sub-profiles, and these are reconnected by a material with very poor thermal conductivity. However, the development is far from over, as the mechanical and thermal behavior of thermally separated profile systems is coordinated with new inventions and innovations.
Die für die thermische Trennung vorwiegend verwendeten Materialien sind: Glasfaserverstärkte Polyamide (GFK-PA), Polypropylen (PP), Polyurethan-Hartschaum (PUR-Hartschaum) und Hartchloroprene. Es bezieht sich dies sowohl auf Ab- standhalter als auch auf Damm-Materialien. In der durch Isolierglas-Mehrfachverglasung erreichten Wärmedämmung über die Glaskomponente durch nichtzirkulierende Luft- bzw. Gaspolster, werden die Einzelscheiben in der Regel jedoch noch durch metallische Abstandhalter fixiert, die die Wärmedämmung der Einglasung verringern.The materials mainly used for the thermal separation are: Glass fiber reinforced polyamides (GFK-PA), polypropylene (PP), rigid polyurethane foam (rigid PUR foam) and hard chloroprene. This applies to both spacers and dam materials. In the thermal insulation achieved through the use of insulating glass multiple glazing via the glass component through non-circulating air or gas cushions, however, the individual panes are usually still fixed by means of metal spacers, which reduce the thermal insulation of the glazing.
Aufgabe der Erfindung ist es speziell, die Wärmedämmung des Einglasungssystems zu steigern, d. h. konkret den k-Wert der Verglasung (kv) zu verbessern.The object of the invention is specifically to increase the thermal insulation of the glazing system, ie specifically to improve the k-value of the glazing (k v ).
Die Aufgabe wird erfindungsgemaß dadurch gelöst, daß die die Isolierglasscheiben 8 der Mehrfachverglasung distanzierenden Abstandhalter 1 einstückig von einem Steg oder Profilrücken 7 ausgehend, an den Fassungsrändern der Isolier- glaεscheiben umlaufend verlegt, in den von den Isolierglas- scheiben abgegrenzten Hohlraum 9 hineinragen, zu den äußeren Glasscheiben hin befestigt und im Übergangsbereich Steg/Abstandhalter hinterschnitten sind und die durch die Hin- terschneidungen gebildeten Hohlräume 2 zwischen Isolierglasscheibe 8, hineinragendem Abstandhalter 1 und Steg 7 mit einem Gummiwerkstoff oder einem gummiartigen Werkstoff elastisch ausgefüllt sind und daß die Abstandhalter zum Distanzieren der Isolierglasscheiben bei der Mehrfachverglasung im Fenster- und Fassadenbau, nach dem erfindungsgemä- ßen Verfahren aus extrudierbarem, während der Extrusion zum Elastomer vernetzbaren Polymerwerkstoff oder einem TPE (thermoplastisch verarbeitbarem Elastomer) oder einem thermoplastischen Polymerwerkstoff besteht.The object is achieved according to the invention in that the spacers 1 spacing the insulating glass panes 8 of the multiple glazing, starting in one piece from a web or profile back 7, are laid around the frame edges of the insulating glazing panes and project into the cavity 9 delimited by the insulating glass panes attached to the outer glass panes and undercut in the web / spacer transition area and the cavities 2 formed by the undercuts between insulating glass pane 8, protruding spacer 1 and web 7 are elastically filled with a rubber material or a rubber-like material and that the spacers for spacing the insulating glass panes in the case of multiple glazing in window and facade construction, using the process according to the invention made of extrudable polymer material that can be crosslinked to form the elastomer or a TPE (thermoplastic elastomer) or a ther plastic polymer material.
Dadurch entfällt die metallische Kältebrücke zwischen den Scheiben.This eliminates the metallic cold bridge between the panes.
Nach einer besonders günstigen Verfahrensweise der Erfindung gelingt die Hinterfüllung der durch Hinterschneidung gebildeten Hohlräume an den Scheibenrändern durch eine gasdichte Hinterfüllung derselben mit einem IIR-Kautschuk - kurz: Butylkautschuk - der ggf. erst bei der Hinterfüllung vernetzt. Dabei entstehen wirksame gasdichte Dichtflächen zwischen den Außenscheiben und den Abstandhaltern, was sehr günstig ist für den Scheibeninnenraum.According to a particularly favorable procedure of the invention, the cavities formed by undercut on the pane edges can be backfilled by a gas-tight backfill of the same with an IIR rubber. In short: butyl rubber - which may not crosslink until it is backfilled. This creates effective gas-tight sealing surfaces between the outer panes and the spacers, which is very favorable for the pane interior.
Durch die Verwendung doppelseitig wirkender Klebebänder zur Befestigung zwischen den äußeren Glasscheiben und dem Abstandhalter mit Acrylkautschuk-Klebeband wird ein sicheres Verarbeitungshandling des Verglasungssystems erreicht. Durch das Aufbringen einer gasdichten Dichtungsfolie auf die Flächen der innenliegenden Stirnseite des Ab- standhalters kann der Gasraum mit einem Trockenmittel ausgestattet werden, das sich umlaufend in einer Schichtdicke bis zu 20 mm vorzugsweise bis zu 10 mm, auf die Dichtungsfolie aufbringen läßt.Through the use of double-sided adhesive tapes for fastening between the outer glass panes and the spacer with acrylic rubber adhesive tape, safe processing handling of the glazing system is achieved. By applying a gas-tight sealing film to the surfaces of the inner end face of the spacer, the gas space can be equipped with a desiccant which can be applied all around in a layer thickness of up to 20 mm, preferably up to 10 mm, to the sealing film.
Besonders wirtschaftlich wird das Verfahren dadurch, daß die Abstandhalter mit dem sie zusammenhaltenden Steg bzw. Profilrücken und ggf. mit den seitlichen Flügeldichtungen einstückig hergestellt werden können. Dies gelingt durch Extrusion und Coextrusion mit extrudierbaren Polymerwerkstoffen wie:The method is particularly economical in that the spacers can be produced in one piece with the web or profile back that holds them together and, if necessary, with the side wing seals. This is achieved through extrusion and coextrusion with extrudable polymer materials such as:
Thermoplasten (Polyvinylchlorid (PVC), Polyethylen (PE), SEBS (Styrol-Ethylen-Butylen-Styrol- Blockcopolymer ) usw. undThermoplastics (polyvinyl chloride (PVC), polyethylene (PE), SEBS (styrene-ethylene-butylene-styrene block copolymer) etc. and
Thermoplastischen Elastomeren (TPE), d. h. thermoplastisch verarbeitbare Elastomere teilvernetzt bzw. mit vernetzten Anteilen, auch Polymerlegierung genannt, die aufgrund ihrer besonderen Molekularstruktur bei Raumtemperatur gummielastische Eigenschaften aufweisen, aber dennoch schweißbar und warmbildsam sind; und insbesondere durch die durch Vulkanisation chemisch zum Elastomer vernetzten natürlichen oder synthetischen Kautschuke (Gummiwerkstoffe).Thermoplastic elastomers (TPE), ie thermoplastically processable elastomers partially cross-linked or with cross-linked portions, also called polymer alloy, which have rubber-elastic properties at room temperature due to their special molecular structure, but are nevertheless weldable and heat-forming; and in particular by the chemical by vulcanization Elastomer cross-linked natural or synthetic rubbers (rubber materials).
Ausschlaggebend dafür ist das Rückstellverhalten derartiger Gummiwerkstoffe, das besonders bei höheren Temperaturen und im Alterungsverhalten im Vergleich zu den Thermoplasten und Thermoplastischen Elastomeren sehr gut erhalten bleibt.The decisive factor for this is the resilience behavior of such rubber materials, which is very well preserved, especially at higher temperatures and in aging behavior compared to the thermoplastics and thermoplastic elastomers.
Dies ist auf das Fehlen fast jeglicher viskoser Verformungsanteile unter Zug-/Druck-/Schubbeanspruchung zurückzuführen. Günstiges Rückstellverhalten garantiert langzeitig hohe Dichtwirkung.This is due to the lack of almost any viscous deformation components under tensile / compressive / shear stress. Favorable resetting behavior guarantees long-term high sealing effect.
Damit wird bei einer erfindungsgemäßen Ausführung der Abstandhalter, die gute Wärmedämmung der Polymerwerkstoffe mit günstigen mechanischen Eigenschaften (hohes Rückstell- vermögen über lange Jahre) gekoppelt.In an embodiment according to the invention, the spacer, the good thermal insulation of the polymer materials and favorable mechanical properties (high resilience over long years) are thus coupled.
Zudem ist es möglich, das Profil in einem Arbeitsgang durch Extrusion sowie ggf. mit Flügeldichtungen durch Coextrusi- on, einstückig wirtschaftlich herzustellen.In addition, it is possible to produce the profile economically in one step by extrusion and, if necessary, with wing seals by coextrusion.
Vernetzter Kautschuk ist dabei beispielhaft gleichzusetzen mit folgenden Gummiwerkstoffen:Cross-linked rubber is, for example, equivalent to the following rubber materials:
Ethylen-Propylen-Copolymer (EPM) Ethylen-Propylen-Dien-Terpolymer (EPDM) , Ethylen-Vinylacetat-Copolymer (EVA), Epichlorhydrin-Kautschuk (CO), Epichlorhydrin-EthylenoxidCopolymer (ECO), Polybutadien-Kautschuk (BR), Polychlorbutadien-Kautschuk (CR),Ethylene-propylene copolymer (EPM), ethylene-propylene-diene terpolymer (EPDM), ethylene-vinyl acetate copolymer (EVA), epichlorohydrin rubber (CO), epichlorohydrin-ethylene oxide copolymer (ECO), polybutadiene rubber (BR), polychlorobutadiene Rubber (CR),
Isobutylen-Isopren-Kautschuk (IIR), ( Butylkautschuk) Isopren-Kautschuk (IR), Acrylnitril-Butadien-Copolymer (NBR), Styvol-Butadien-Copolymer (SBR) oder Naturkautschuk (NR) oder deren Verschnitte.Isobutylene-isoprene rubber (IIR), (butyl rubber) isoprene rubber (IR), acrylonitrile-butadiene copolymer (NBR), Styvol-butadiene copolymer (SBR) or natural rubber (NR) or their blends.
Dabei sind durch Coextrusion auch unterschiedliche Materialbereiche und damit Materialhärten realisierbar, die es erlauben, den Stegbereich oder den Abstandhalter oder die Flügeldichtung in ihrer Härte an die Erfordernisse anzupassen.Different material areas and thus material hardnesses can be realized by coextrusion, which allow the hardness of the web area or the spacer or the wing seal to be adapted to the requirements.
In Figur 1 ist der Einglasungsmechanismus für die erfindungsgemäße Verfahrensweise für den Fall der Isoliervergla- sung mit zwei bzw. drei Isolierglasscheiben 8 dargestellt. Die Schnittzeichnung gibt dabei die Lage aller am Einglasungsverfahren beteiligten Verglasungsteile (s. Bezugszeichenliste) im Einbauzustand zueinander an.FIG. 1 shows the glazing mechanism for the procedure according to the invention for the case of insulating glazing with two or three insulating glass panes 8. The sectional drawing shows the position of all glazing parts involved in the glazing process (see list of reference symbols) in relation to each other in the installed state.
Wesentlich ist dabei, daß bei drei oder mehr Isolierglas- scheiben, nur die äußeren Scheiben mit der hinterfüllten Hinterschneidung den gasdichten Abschluß zur Umgebung hin sichern.It is essential that in the case of three or more insulating glass panes, only the outer panes with the backfilled undercut secure the gas-tight seal to the environment.
Hineingestellte Scheiben bewirken lediglich, daß eine Gaszirkulation und damit der Wärmetransport durch Konvektion weitgehend unterbleibt.Placed panes only have the effect that gas circulation and thus the heat transport by convection are largely avoided.
In Figur 2 wird deutlich, wie der Abstandhalter 1 über den Profilrücken (Steg) 7 einstückig mit Flügeldichtungen 5 extrudiert sein kann, so daß schon zueinander fixierte Scheiben 8 per Verglasungsblock in die vorgesehenen Aufnahmenuten des Rahmens eingebaut werden können.In Figure 2 it is clear how the spacer 1 over the profile back (web) 7 can be extruded in one piece with wing seals 5, so that already fixed to each other panes 8 can be installed by glazing block in the intended grooves of the frame.
Figur 3 zeigt die im eingebauten Zustand erreichte Endposition im Profilsystem des Fensters oder auch einer Fassade. Figure 3 shows the end position reached in the installed state in the profile system of the window or a facade.
