Description

[0001] Die Erfindung betrifft eine Dämmplatte, insbesondere zur Wärmeisolation von Aussenfassaden, Wänden oder anderen Teilen von Gebäuden aus expandiertem Polystyrol (EPS) bestehend. The invention relates to an insulation board, in particular for the thermal insulation of exterior facades, walls or other parts of buildings made of expanded polystyrene (EPS).

[0002] Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung derartiger Dämmplatten. The invention further relates to a method for producing such insulation boards.

[0003] Dämmplatten aus expandiertem Polystyrol zur Isolation von Gebäudeteilen u. a. sind hinlänglich bekannt. Sie werden z. B. durch Expansion von Styrolpolymerisatpartikeln in Dampfkammern und nachfolgenden Zuschnitt hergestellt. Foam boards made of expanded polystyrene for the insulation of building parts u. a. are well known. They are z. B. prepared by expansion of styrene polymer particles in steam chambers and subsequent cutting.

[0004] Hauptsächlich werden Dämmplatten aus pigmentfreien Styrolpolymerisatpartikeln hergestellt. Mainly insulation boards are made from pigment-free styrene polymer particles.

[0005] Zwecks Verbesserung der Dämmwirkung werden neben dickeren Platten auch solche hergestellt, die zudem noch Partikel mit dunklen Pigmenten enthalten, z. B. aus Russ, Farbstoffen, Grafit u. a. Der Anteil der pigmentierten Styrolpolymerisatpartikel kann 10-90 Gew.-% betragen (DE-U-20 315 226 und EP-A-2 010 601, siehe auch EP-A-0981 574, bei der eine Verteilung 50:50 als besonders vorteilhaft angesehen wird). In order to improve the insulating effect, in addition to thicker plates, those are also prepared which also contain particles with dark pigments, for. B. from soot, dyes, graphite u. a. The proportion of the pigmented styrene polymer particles may be 10-90% by weight (DE-U-20 315 226 and EP-A-2 010 601, see also EP-A-0 981 574, in which a 50:50 distribution is particularly advantageous is seen).

[0006] Gemäss EP-A-1 815 077 können die Dämmplatten dabei auch aus zwei Teilen bestehen, einem Teil mit überwiegender Dämmwirkung, der aus einem grauen expandierten Polystyrol besteht und athermane Stoffe für eine zusätzliche Funktion enthält und einem zweiten Teil aus Hartschaum mit wenigstens einer weiteren Schutzeigenschaft. Die athermanen Stoffe können wiederum Russ, Grafit u. a. sein und die als Infrarotabsorber bzw. -reflektoren fungieren. Der andere Plattenteil erfüllt z.B. eine Schallschutzfunktion. Beide Teile sind thermisch miteinander verbunden, bezeichnet als thermisches verschweissen, bei dem erhitzte Metallnadeln die aufeinanderliegenden Teile durchstechen. Dadurch werden im Umfeld der Nadeln verbindende Kontaktflächen gebildet. Die Anzahl der Kontaktflächen entspricht der Anzahl der Nadeln und es entsteht keine durchgehende Verbindungsfläche der Teile. According to EP-A-1 815 077, the insulation boards can also consist of two parts, a part with predominant insulating effect, which consists of a gray expanded polystyrene and athermane substances for an additional function and a second part of hard foam with at least another protective property. The athermanous substances may in turn contain soot, graphite and the like. a. be and act as infrared absorbers or reflectors. The other plate part satisfies e.g. a soundproofing function. Both parts are thermally bonded together, referred to as thermal welding, in which heated metal needles pierce the superposed parts. As a result, connecting contact surfaces are formed in the vicinity of the needles. The number of contact surfaces corresponds to the number of needles and there is no continuous connection surface of the parts.

[0007] Bei einer ähnlichen Dämmplatte gemäss DE-U-8 226 114, die insbesondere für Flachdächer verwendet wird, besteht die Platte aus einer dämmenden Grundschicht aus Hartschaum und einer nach aussen gerichteten Schutzschicht aus einem Fasermaterial. In der EP-A-1 213 118 ist ein Verfahren zur Schaumstoffplatte offenbart, die aus zwei Ausgangsplatten gebildet wird. Die Ausgangsplatten, die an den Berührungsflächen extrusionshautlos sein sollen, werden mittels eines diffusionsoffenen Klebers und oder durch mechanische Verbindungselemente teilflächig miteinander verbunden. Die mechanischen Verbindungselemente bestehen dabei bevorzugt aus dem Werkstoff der Ausgangsplatten. In a similar insulation board according to DE-U-8 226 114, which is used in particular for flat roofs, the plate consists of a insulating base layer of hard foam and an outwardly directed protective layer of a fiber material. In EP-A-1 213 118 there is disclosed a method of foam sheet formed from two starting sheets. The starting plates, which are to be extrusion skinless at the contact surfaces, are connected to one another by means of a diffusion-open adhesive and / or by mechanical connecting elements over part of the area. The mechanical connecting elements are preferably made of the material of the output plates.

[0008] Die Aufgabe der Erfindung besteht nun darin, eine Dämmplatte, insbesondere zur Wärmeisolation von Aussenfassaden, Wänden oder anderen Teilen von Gebäuden vollständig aus expandiertem Polystyrol (EPS) bestehend zu schaffen, die unterschiedliche Schutzfunktionen erfüllen. The object of the invention is therefore to provide an insulating board, in particular for the thermal insulation of external facades, walls or other parts of buildings consisting entirely of expanded polystyrene (EPS), which fulfill different protective functions.

[0009] Die Aufgabe ist mit den Merkmalen des Patentanspruchs 1 gelöst. Erfindungsgemäss besteht die Dämmplatte aus zwei Schichten bzw. Ausgangsplatten, d. h. einer dunklen und dämmenden Reflektorschicht und einer Deckschicht mit einer zusätzlichen Schutzfunktion, wobei beide Schichten kleberfrei und vollflächig miteinander verbunden sind. The object is solved with the features of claim 1. According to the invention, the insulation board consists of two layers or output plates, d. H. a dark and insulating reflector layer and a cover layer with an additional protective function, wherein both layers are bonded together adhesive-free and over the entire surface.

[0010] Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen offenbart. So enthält die dämmende Reflektorschicht in bekannter Weise dunkle Pigmente enthaltende Partikel, insbesondere Grafitpartikel. Die dämmende Reflektorschicht ist der zu dämmenden Wand o. dgl. zugewandt. Preferred embodiments are disclosed in the dependent claims. Thus, the insulating reflector layer contains in a known manner dark pigments containing particles, in particular graphite particles. The insulating reflector layer is facing the wall to be insulated or the like.

[0011] Die Deckschicht besteht vollständig aus pigmentfreien Partikeln und ist nach aussen gewandt, wobei die Deckschicht deutlich dünner als die dämmende Schicht ist, in einem Verhältnis kleiner 10:90. The cover layer consists entirely of pigment-free particles and is turned outwards, wherein the cover layer is significantly thinner than the insulating layer, in a ratio of less than 10:90.

[0012] Die Verbindung der Schichten bzw. Ausgangsplatten erfolgt z. B. durch thermisches Verkleben oder Verschweissen. The compound of the layers or output plates z. B. by thermal bonding or welding.

[0013] Die Dämmplatte ist eine Verbundplatte aus weissem und pigmentiertem EPS. The insulation board is a composite panel of white and pigmented EPS.

[0014] Die Ausgangsplatten sind an Ihren Auflageflächen miteinander verbunden, wobei bevorzugt zunächst eine Sandwichplatte, bestehend aus zwei Reflektorplatten mit dazwischenliegender Deckplatte gebildet ist und nachfolgend die Deckplatte so geschnitten wird, dass zwei fertige Dämmplatten und ggf. eine Restplatte entstehen. The output plates are connected to each other at their bearing surfaces, preferably first a sandwich plate consisting of two reflector plates is formed with intermediate cover plate and subsequently the cover plate is cut so that two finished insulation boards and possibly a residual plate arise.

[0015] Der Erfindung liegt weiterhin die Aufgabe zugrunde, ein Verfahren zur Herstellung von Dämmplatten aus expandiertem Polystyrol (EPS) zu entwickeln, das eine vereinfachte und anforderungsgerechte Verarbeitung von Dämmplatten ermöglicht. The invention is further based on the object to develop a process for the production of insulating panels of expanded polystyrene (EPS), which allows a simplified and requirement-based processing of insulation boards.

[0016] Diese Aufgabe ist mit den Merkmalen des Patentanspruchs 4 gelöst. Erfindungsgemäss werden Dämmplatten gemäss Patentanspruch 1 zunächst als Sandwich gebildet, wobei eine Deckschicht bzw. Deckplatte an der Vorderseite und an der Rückseite ganzflächig mit einer Dämmschicht bzw. Reflektorplatte verbunden ist, bevorzugt kleberfrei. Anschliessend und ggf. erst vor Ort wird die Deckplatte parallel zur Längsseite mit mindestens einem Schnitt getrennt, so dass im Ergebnis zwei erfindungsgemässe Dämmplatten entstehen. This object is solved with the features of claim 4. According to the invention insulation boards are first formed as a sandwich according to claim 1, wherein a cover layer or cover plate is connected at the front and on the back over the entire surface with an insulating layer or reflector plate, preferably adhesive-free. Subsequently, and possibly only on site, the cover plate is separated parallel to the longitudinal side with at least one section, so that arise as a result, two inventive insulation boards.

[0017] In einer weiteren Ausführungsform des Verfahrens wird die Deckplatte mit zwei Schnitten gleichzeitig durchtrennt, wobei zusätzlich eine «Restplatte» zu anderweitiger Verwendung entsteht. In a further embodiment of the method, the cover plate is cut with two cuts at the same time, in addition, a "residual plate" is created for other uses.

[0018] Bei Bedarf kann die Ausgangssandwichplatte um weitere Platten erweitert werden, d. h. auf die Reflektorplatten folgt je eine weitere Deckplatte etc. If necessary, the Ausgangsandwichplatte be extended by more plates, d. H. on the reflector plates is followed by a further cover plate, etc.

[0019] Mit der Erfindung wird das Problem gelöst, dass dunkle, pigmententhaltende, dickere Reflektorplatten (Dämmplatten) aus EPS zwar eine bessere Dämmung als pigmentfreie Platten aus EPS aufweisen, doch bei grösseren Temperaturunterschieden eine geringere Formstabilität aufweisen. Die Deckschicht wirkt als Barriere für die Dämmschicht, so dass eine höhere Formstabilität erreicht wird und nur in geringerem Masse dämmend. Die einzelnen Schichten bzw. Ausgangsplatten bestehen aus dem gleichen Grundwerkstoff, was Herstellung, Lagerung und Verarbeitung auf der Baustelle deutlich vereinfacht. With the invention, the problem is solved that dark, pigment-containing, thicker reflector plates (insulation boards) made of EPS, although better insulation than pigment-free panels of EPS, but have greater dimensional stability at greater temperature differences. The cover layer acts as a barrier for the insulating layer, so that a higher dimensional stability is achieved and only to a lesser extent insulating. The individual layers or starting plates consist of the same base material, which considerably simplifies production, storage and processing on the construction site.

[0020] Die Erfindung wird nachfolgend in einem Ausführungsbeispiel anhand einer Zeichnung näher beschrieben. In der Zeichnung die <tb>Fig. 1:<sep>eine Dämmplätte <tb>Fig. 2:<sep>eine Ausgangssandwichplatte.The invention will be described below in an embodiment with reference to a drawing. In the drawing the <Tb> FIG. 1: <sep> an insulation plate <Tb> FIG. 2: <sep> an output sandwich plate.

[0021] EPS-Platten werden in bekannter Weise durch Expansion von Styrolpolymerisatpartikeln in Dampfkammern hergestellt. Gefertigt werden sowohl Deckplatten 2 ́ die nur Styrolpolymerisatpartikel enthalten, als auch höher dämmende Reflektorplatten 1, die pigmentierte Styrolpolymerisatpartikel aufweisen. EPS sheets are prepared in a known manner by expansion of styrene polymer particles in steam chambers. Both cover plates 2 which contain only styrene polymer particles and also higher-attenuation reflector plates 1 which have pigmented styrene polymer particles are produced.

[0022] Es wird zunächst ein Block aus zwei parallel nebeneinander angeordneten Reflektorplatten 1, zwischen denen eine Platte 2 ́ angeordnet ist hergestellt, wobei die Platten 1, 2 ́ an Kontaktflächen 3 kleberfrei und vollständig miteinander verbunden werden. It is first a block of two parallel juxtaposed reflector plates 1, between which a plate 2 is arranged, wherein the plates 1, 2 are adhesively and completely connected to contact surfaces 3 together.

[0023] Anschliessend wird die Platte 2 ́ mittels eines nicht näher bezeichneten Schneidwerkzeuges 4 mit zwei parallelen Schnitten durchtrennt, wobei die Schnittlinien 5 auch parallel zur Linie der Kontaktflächen 3 verlaufen. Es entstehen somit zwei Dämmplatten, jeweils bestehend aus einer dämmenden Reflektorschicht (Reflektorplatte 1) und einer Deckschicht (Deckplatte 2), wobei die Deckplatte 2 wesentlich dünner als die dämmende Reflektorplatte 1 ist, bevorzugt kleiner 10%. Subsequently, the plate 2 is severed by means of an unspecified cutting tool 4 with two parallel cuts, wherein the cut lines 5 are also parallel to the line of the contact surfaces 3. This results in two insulation boards, each consisting of an insulating reflector layer (reflector plate 1) and a cover layer (cover plate 2), wherein the cover plate 2 is substantially thinner than the insulating reflector plate 1, preferably less than 10%.

[0024] Es verbleibt ein Schnittrest der Platte 2 ́, der ebenfalls einer geeigneten Verwendung zugeführt werden kann. There remains a cut remnant of the plate 2, which can also be fed to a suitable use.

[0025] Der Block kann auch um weitere Sandwichanordnungen (auf mindestens eine der Platten 1 folgt wieder eine Platte 2 ́ etc.) erweitert sein um gleichzeitig mehrere derartige Schneidvorgänge ausführen zu können. The block can also be extended to further sandwich arrangements (at least one of the plates 1 follows again a plate 2, etc.) to be able to perform several such cutting operations simultaneously.

[0026] Der Schneidvorgang kann unmittelbar auf die Blockherstellung folgen oder auch erst auf einer Baustelle ausgeführt werden. The cutting process can directly follow the block production or even be carried out on a construction site.
