Description
Zeichtbauplatte und Verfahren zu deren Herstellung Die Erfindung betrifft eine Leichtbauplatte , bestehend aus einer Hartschaumplatte, die beidseits mittels einer Bindemittelschicht mit einer Deckschicht aus Holzspänen und Zement verbunden ist.Drawing board and method for the production thereof The invention relates to a lightweight board, consisting of a rigid foam board that is secured on both sides by means of a binder layer with a top layer of wood chips and cement is.
Es ist bekannt, Zeiehtbauplatten mit einem Hartschaumkern und Deckschichten aus Holzspänen und Zement herzustellen.' .Dabei wird die Deckschicht aus feuchten Holzspänen mit Zement in Verbindung gebracht und die Hartschaumplatte darüber gelegt.- Der Zement hat die Aufgabe, einesteils die Holzspäne vollständig zu umhüllen und l@ miteinander zu verbinden und andernteils die Bindung 1 zu der Hartschaumplatte zu bewirken.It is known, building panels with a rigid foam core and cover layers from wood chips and cement. ' The top layer becomes moist Wood chips were brought into contact with cement and the hard foam board was placed over it. The task of the cement is, on the one hand, to completely enclose the wood chips and l @ to connect with each other and on the other hand the bond 1 to the rigid foam board to effect.
Dem vorteilhaften Einsatz solcher Leiohtbauplatten steht die ungenügende Haftung der Deoksohieht,-die oft ganzflächig von der als Isollereohioht wirkenden Hartschaumplatte abschert, entgegen.The advantageous use of such loan building boards is counteracted by the insufficient adhesion of the deodorant layer, which often shears over the entire surface of the rigid foam board acting as Isollereohioht.
Es sind Versuche bekannt, die Abscherfestigkeit yon. Platten aus HolzspKnen und Zement von Hartschaumplatten dadurch zu erhöhen,dass die Hartschaumplatte vor dem Auflegen auf die-Deckschicht mit einer Zementsehlempe eingestrichen wird. Dadurch wird zwar die Haftung zischen Deckschicht und Hartschaumplatte verbessert, jedoch kommt es immer wieder vor,dass diese sich trennen. Das-,rasche Absetzen des Zements in der vorbereiteten Zementechlempe, . deren hohes spezifisches Gewicht und ihre zähe Konsistenz machen jedoch den maschinellen Auftrag der Schlempe praktisch unmöglich. Die Bindemittelschicht aus Zement, die als Schlempe aufgetragen wird, liegt auch nicht in homogener Verteilung - des Zements gegenüber den:Holzspänen vor, vielmehr besteht im Fertigerzeugnis ein Konzentrationsgefälle in Richtung von der Hartschaumplatte zu der Deckschicht. Das Auftragen der.Zementschlompe ist aus Kostengründen unwirtschaftlich. Schliesslidh verliert eine solche Platte zufolge des zusätzlichen Aufwandes an Zement weitgehend die Eigenschaft einer Ieohtbauplatte. strukturell gesehen ergeben sich durch die inhomoggne Schiohtung des Zements in den Deckäohlchten Nachteile für die Verarbeitbarkeit, $.B. beim Ablgen -und Xageln. Es ist auch bereits bekannti-zur Vermeidung des Abscherene in das Holzspäne-Zement-Gemisch vor dem Abbinden des Zemente Kunststoffdispersionen einzuarbeiten. Aber auch dadurch wurde eine ausroichende Haftung zwischen der Hartschaumplatte und den Deckschichten nicht erreicht. Die'Ferti- _ gung vrurde sufgegeben,weil die Kosten für den erforderlichen hohen-Anteil an Kunststoffdispersionen an dem Holzspäne-Zement-Gemisch die Fertigung unwirtschaftlich machten. Ueberdies ist es natürlich völlig unnütz, die Kunststoffdispersion dort anzuordnen, 1io sie keine Bindemittelwirkung ausübt. Die Bindung der Holzspäne in der Deckschicht wird durch den anwesenden Zement in völlig ausreichender Weise besorgt. There are known attempts yon the shear strength. To increase boards made of wood chips and cement of rigid foam boards by coating the rigid foam board with a cement paste before placing it on the top layer. This improves the adhesion between the top layer and the rigid foam board, but it happens again and again that these separate. The rapid settling of the cement in the prepared cement clam. However, their high specific weight and their tough consistency make the mechanical application of the pulp practically impossible. The cement binding agent layer, which is applied as slurry, is also not homogeneously distributed between the cement and the wood chips , rather there is a concentration gradient in the finished product in the direction from the rigid foam board to the top layer. The application of the cement slurry is uneconomical for reasons of cost. Finally, due to the additional expenditure of cement, such a panel largely loses the property of a construction panel. From a structural point of view, the inhomogeneous layering of the cement in the cover walls results in disadvantages for the workability, $ .B. when filing and Xageln. It is also already known to incorporate plastic dispersions into the wood chips-cement mixture before the cement sets, in order to avoid shearing. But even this did not achieve sufficient adhesion between the rigid foam board and the cover layers. The production was given because the costs for the required high proportion of plastic dispersions in the wood chip-cement mixture made the production uneconomical. In addition, it is of course completely useless to arrange the plastic dispersion there where it does not have a binding agent effect. The cement that is present ensures that the wood chips are bound in the top layer in a completely sufficient manner.
Die Erfindung bezweckt nun die Herstellung einer Leichtbauplatte aus einer Hartschaumplatte mit Deckschichten aus Holzspänen und Zement,die die Eigenschaft einer wirklichen Leiehtbauplatie hat, in einfacher Weise hergestellt werden kann und bei der das Abscheren der Deckschicht von der Hartschaumplatte praktisch unmöglich ist" Eine Leiehtbauplatte gem7nes der Erfindung, bestehend aus einer Hartschaumplatte, die beidseits mittels einer Bindemittelschicht mit einer Deckschicht aus Holzsp'-ynen und Zement verbunden ist, ist im wesentlichen dadurch gekennzeichnet, dass die Bindemittelschicht aus einem gehärteten Epoxidharzfilm besteht.The invention now aims to produce a lightweight panel a rigid foam board with top layers of wood chips and cement that make the property a real Leichtbauplatie has, can be produced in a simple manner and in which the shearing of the cover layer from the rigid foam board is practically impossible is "A lightweight building board according to the invention, consisting of a rigid foam board, on both sides by means of a binder layer with a top layer of wood chips and cement is essentially characterized by that the binder layer consists of a hardened epoxy resin film.
Die Herstellung einer solchen Leichtbauplatte wird im wesentlichen
dadurch vorgenommen,dase beidseits auf die Hartschaumplatte eine Emulsion aus einem
Bpoxi.dharzvorprodukt und einem Kaltharter aufgebracht,dann die Deckschichtmasse,die
aus Holzspänen, nicht abgebundenem Zement und Waseer besteht, bei. dseits aufgebracht,
das Gebilde in an sich bekannter Weise in eine Presse verbracht und hier einesteils.$um
Hirten des Bpoxidharzes und andernteils zum Abbinden des Zements vibhrend wenigstens
24 Stunden unter Druck aufbewahrt wird.
Ale Epoxidharzvorprodukte und als Kalthärter können handelsübliche
Erzeugnisse verwendet werden.-Die Leiohtbauplatten gemäss der Erfindung haben,wie
Untersuchunjen ergeben haben, einen so grossen Abecherwider-
.Es war nicht zu erwarten gewesen, dass die Ausbildung des duroplastisehen Epoxidharzfilmes glatt verläuft, vielmehr musste befürchtet werden,dass bei der Wasserabgabe während des Aushärtens des Filmes aus Epoxidharzvorprodukt b$w. während der Zerstörung der Dispersion, Wasser nicht nur nach der Zementseite,sondern auch nach der Seite der Hartschaumplatte abgegeben wird und hier eine die Haftung zwischen der Hartechaumplatte und dem duroplastischen Film verhindernde Wasserechicht alasgebildet wirr.. It was not to be expected that the training of the thermoset vision Epoxy resin film runs smoothly, rather it had to be feared that with the Release of water during curing of the epoxy resin precursor film b $ w. while the destruction of the dispersion, water not only on the cement side, but also is released to the side of the rigid foam board and here the adhesion between The hard foam sheet and the thermosetting film prevent water layer from being formed confused
