Description
Die Erfindung betrifft ein wärme- und schalldämmendes Verbundelement aus einem Kunststoff-Hartschaum, z.B. einem Polystyrol-Extruderschaum (XPS) und einer Gipskarton-Platte.The invention relates to a heat and sound insulating composite element made of a rigid plastic foam, e.g. a polystyrene extruder foam (XPS) and a plasterboard.
Verbundelemente aus XPS-Platten und Gipskarton-Platten werden in zunehmendem Maße zur Innendämmung von Außenwänden bei Wohngebäuden angewandt. Derartige Verbundelemente zeichnen sich zwar durch eine hervorragende Wärmedämmung aus, es hat sich aber gezeigt, daß ihre Schalldämmung für viele Anwendungszwecke nicht ausreichend ist, daß sie sogar zu einer Verschlechterung der Schalldämmung gegenüber einer ungedämmten Wand führen können. So kann beispielsweise die Schallängsleitung an Wänden, die wesentlich für die Schallübertragung zwischen zwei Nachbarräumen verantwortlich ist, bei Verwendung der genannten Verbundelemente höher sein als bei nichtgedämmten Wänden. Ein orientierendes Maß für den Einfluß zusätzlicher Wärmedämmung ist die Schallübertragung von einem Senderaum in einen benachbarten Empfangsraum, guantifiziert durch das "Einfügedämmaß" nach DIN 4109. Bei einem Verbund aus einer 40 mm dicken XPS-Platte und einer 9,5 mm dicken Gipskarton-Platte, die durch einen herkömmlichen Polyurethan-Kleber miteinander verbunden sind, beträgt das Einfügedämmaß 28 dB (A). Mit solchen Verbundplatten als innenliegende Zusatzdämmung von Außenwänden wird die Schallängsleitung der Außenwand im Vergleich zur ungedämmten Ausführung erhöht, d.h., die Schalldämmung wird negativ beeinflußt.Composite elements made of XPS and plasterboard are increasingly being used for the interior insulation of external walls in residential buildings. Such composite elements are characterized by excellent thermal insulation, but it has been shown that their sound insulation is not sufficient for many applications, that they can even lead to a deterioration of the sound insulation compared to an uninsulated wall. For example, the longitudinal sound conduction on walls, which is essentially responsible for the sound transmission between two neighboring rooms, can be higher when using the composite elements mentioned than with non-insulated walls. A guideline for the influence of additional thermal insulation is the sound transmission from a transmission room into an adjacent reception room, guaranteed by the "insertion loss" according to DIN 4109. With a composite of a 40 mm thick XPS board and a 9.5 mm thick plasterboard board , which are connected to each other by a conventional polyurethane adhesive, the insertion loss is 28 dB (A). With such composite panels as additional internal insulation of external walls, the longitudinal sound conduction of the external wall is increased in comparison to the uninsulated version, i.e. the acoustic insulation is negatively affected.
Der Erfindung lag also die Aufgabe zugrunde, die Schalldämmung bei Verbundelementen aus Kunststoff-Hartschaum und Gipskarton-Platten zu verbessern.The invention was therefore based on the object of improving the sound insulation in composite elements made of rigid plastic foam and plasterboard.
Diese Aufgabe wird dadurch gelöst, daß zwischen die Hartschaum-Platten und die Gipskarton-Platten eine Schicht aus einem flexiblen, offenzelligen Duromerschaumstoff angeordnet ist.This object is achieved in that a layer of a flexible, open-cell thermoset foam is arranged between the rigid foam panels and the plasterboard panels.
Bevorzugter Hartschaum ist Polystyrol-Extruderschaum. Er zeichnet sich gegenüber anderen Schaumstoffen durch gute Steifigkeit und Druckfestigkeit aus. Die Dichte der XPS-Platten liegt im allgemeinen zwischen 25 und 40 g·l⁻¹, ihre Dicke vorzugsweise zwischen 10 und 200 mm. Die Wärmeleitfähigkeit ist im allgemeinen kleiner als λ = 0,035 W·m⁻¹·K⁻¹. Neben XPS-Platten sind auch solche aus Polystyrol-Partikelschaum, aus hartem Polyurethanschaum sowie aus Phenolharzschaum nach DIN 18 164 geeignet.The preferred rigid foam is polystyrene extruder foam. Compared to other foams, it is characterized by good rigidity and pressure resistance. The density of the XPS plates is generally between 25 and 40 g · l⁻¹, their thickness preferably between 10 and 200 mm. The thermal conductivity is generally less than λ = 0.035 W · m⁻¹ · K⁻¹. In addition to XPS boards, such are also made Polystyrene particle foam, made of hard polyurethane foam and phenolic resin foam according to DIN 18 164.
Gipskartonplatten C sind ebenfalls wohlbekannt. Sie bestehen aus einer 5 bis 20 mm dicken Gipsschicht, die beidseitig mit Karton laminiert ist. Als Schicht C sind auch Fasergipsplatten geeignet.Gypsum plasterboards C are also well known. They consist of a 5 to 20 mm thick plaster layer, which is laminated on both sides with cardboard. Gypsum plasterboards are also suitable as layer C.
Die erfindungsgemäße Zwischenschicht B besteht aus einem flexiblen, offenzelligen Schaumstoff. Geeignet sind Schaumstoffe aus Kondensationsharzen auf Basis von Melamin-, Harnstoff- und Phenol-Formaldehyd, daneben aber auch Polyurethan-Weichschäume. Besonders bevorzugt sind elastische Schaumstoffe auf Basis von Melaminharzen, wie sie z.B. in EP-B 71 672 beschrieben sind. Diese Schaumstoffe haben im allgemeinen ein spezifisches Gewicht von 5 bis 100 g/l, insbesondere von 8 bis 20 g/l und eine Dicke von 10 bis 100 mm, vorzugsweise von 20 bis 50 mm.The intermediate layer B according to the invention consists of a flexible, open-cell foam. Foams made from condensation resins based on melamine, urea and phenol formaldehyde are suitable, but also flexible polyurethane foams. Elastic foams based on melamine resins, as are e.g. are described in EP-B 71 672. These foams generally have a specific weight of 5 to 100 g / l, in particular 8 to 20 g / l and a thickness of 10 to 100 mm, preferably 20 to 50 mm.
Die Abbildung zeigt eine wärmegedämmte Außenwand (1) mit zwei Innenräumen, die durch eine Innenwand (2) voneinander getrennt sind. An der Innenseite der Außenwand ist ein wärme- und schallisolierendes Verbundelement angebracht, welches aus drei Schichten besteht: einer XPS-Platte (3), einer Zwischenschicht (4) aus einem offenzelligen Duromerschaumstoff und einer Gipskarton-Platte (5).The figure shows a thermally insulated outer wall (1) with two interior spaces that are separated from each other by an inner wall (2). On the inside of the outer wall is a heat and sound insulating composite element, which consists of three layers: an XPS board (3), an intermediate layer (4) made of an open-cell thermoset foam and a plasterboard board (5).
Das Dickenverhältnis der Schaumstoffschichten A:B kann in weiten Grenzen zwischen 15:1 und 1:15 schwanken, es liegt vorzugsweise zwischen 10:1 und 1:10 und insbesondere zwischen 4:1 und 1:4.The thickness ratio of the foam layers A: B can vary within wide limits between 15: 1 and 1:15, it is preferably between 10: 1 and 1:10 and in particular between 4: 1 and 1: 4.
Die einzelnen Schichten sind durch übliche Klebstoffe miteinander verbunden, beispielsweise auf Basis von Polyurethanen oder Acrylaten, die gegebenenfalls elastisch eingestellt oder auch geschäumt sein können.The individual layers are bonded to one another by conventional adhesives, for example based on polyurethanes or acrylates, which can optionally be adjusted elastically or can also be foamed.
Ein beispielhafter Verbund besteht aus folgenden Schichten:
- A. 40 mm XPS (STYRODUR der BASF) mit einer Dichte von 25 g·l⁻¹,
- B. 10 mm eines elastischen Schaumstoffs aus einem Melamin/Formaldehyd-Harz (BASOTECT der BASF) mit einer Dichte von 10 g·l⁻¹,
- C. 9,5 mm Gipskarton.
- A. 40 mm XPS (STYRODUR from BASF) with a density of 25 g · l⁻¹,
- B. 10 mm of an elastic foam made of a melamine / formaldehyde resin (BASOTECT from BASF) with a density of 10 g · l⁻¹,
- C. 9.5mm plasterboard.
Das Einfügedämmaß nach DIN 4104 betrug 31 dB (A).The insertion loss according to DIN 4104 was 31 dB (A).
Ein anderer Verbund besteht aus
- A. 10 mm STYRODUR
- B. 40 mm BASOTECT
- C. 12,5 mm Gipskarton
- A. 10 mm STYRODUR
- B. 40 mm BASOTECT
- C. 12.5mm plasterboard
Bei beiden Beispielen wird eine deutliche Erhöhung des Einfügedämmaßes und damit bei Verwendung als innenliegende zusätzliche Wärmedämmung eine Verminderung der Schallängsleitung erzielt.In both examples, a significant increase in the insertion loss and thus a reduction in the longitudinal sound conduction is achieved when used as additional internal insulation.
