Description
Die Erfindung betrifft eine Schichtverbundplatte mit einer Kernschicht aus einem im wesentlichen aus einem ausgehärteten anorganischen Bindemittel, gegebenenfalls Zuschlägen und anderen Zusatzstoffen bestehenden anorganischen Material und mindestens einseitiger faserbewehrter Deckschicht, die kraftübertragend mit der Kernschicht verbunden istThe invention relates to a laminated composite panel with a core layer consisting essentially of one cured inorganic binders, if necessary aggregates and other additives inorganic material and at least one-sided fiber-reinforced cover layer that transmits force with the core layer is connected
Das anorganische Material kann aus Zement, Kalk, Gips, Magnesium und/oder Mischungen von Magnesiumoxid mit Magnesiumchlorid bestehen. Faserbewehrungen in Schichtverbundplatten dienen zur Erhöhung der Festigkeit und es werden hierfür anorganische und/oder organische Fasern in geschnittener Form, als Endlosfasern, als flächenhafte Gebilde oder als Rovings verwendetThe inorganic material can consist of cement, lime, plaster of paris, magnesium and / or mixtures of magnesium oxide with magnesium chloride. Fiber reinforcements in composite panels are used to increase the strength and there are inorganic and / or organic fibers in cut form, as Endless fibers, used as flat structures or as rovings
Ein derartiges mehrschichtiges plattenförmiges Bauelement ist aus der DE-OS 23 52 843 bekannt Es ist aus unterschiedlichen anorganischen Schichten zusammengesetzt Auf einer Kernschicht aus Leichtbeton mit haufwerksporigem Gefüge ist beidseitig je eine gefügedichte, faserbewehrte Schicht aus faserverstärktem Zementmörtel aufgebracht Alle Schichten dieses Verbundelementes sind zementgebunden. In der Druckschrift wird darauf hingewiesen, daß in der äußeren Feingefügeschicht an Stelle von Zementmörtel ein Kunstharzmörtel verwendet werden kann, jedoch nur dann, wenn auch für den Leichtbeton der Kernschicht ein entsprechendes Bindemittel verwendet wird. Durch diese Bauweise treffen keine im chemischen und physikalischen Verhalten grundsätzlich verschiedene Materialien in Grenzbereichen des Werkstoffes aufeinander und daher sind keine Grenzschichtprobleme zu befürchten. Solche Probleme treten aber sehr wohl bei Schichtverbundplatten aus Schichten unterschiedlicher Grundstoffe, nämlich einerseits anorganischer und andererseits organischer Materialien, auf.Such a multilayer, plate-shaped component is known from DE-OS 23 52 843. It is composed of different inorganic layers On a core layer made of lightweight concrete with a pore structure, there is one on both sides Structured, fiber-reinforced layer of fiber-reinforced cement mortar applied. All layers of this Composite elements are cement-bound. In the publication it is pointed out that in the outer Fine structure layer instead of cement mortar a synthetic resin mortar can be used, however only when a suitable binding agent is also used for the lightweight concrete of the core layer. By this type of construction does not meet any fundamentally different chemical and physical behavior Materials in boundary areas of the material on each other and therefore no boundary layer problems are to be expected fear. However, such problems do occur with composite panels made of layers of different types Basic materials, namely on the one hand inorganic and on the other hand organic materials.
Ferner ist aus der DE-AS 1174 679 ein Naß-in-Naß-Verfahren zur Herstellung von mit Kunststoff vergüteten Fertigteilen aus Beton bekannt, bei dem auf eine nicht ausgehärtete Kunstharzschicht Mörtel aufgebracht und die Schichten beispielsweise durch Rütteln ineinander verdichtet werden. Auf diese Weise werden Ornament- und Dekorationsschichten in den verschiedensten Gestaltungen, jedoch kein tragender Sandwichverbund erhalten. Die Kunststoffvergütung führt hier zu einem Mischkörper, in dem eine hydraulische Phase und eine organische Phase nebeneinander abbinden. Die Hydratationsprodukte der hydraulischen Phase liegen wie Inseln in der Harzmasse und beeinträchtigen deren vorteilhafte Biege- undFurthermore, from DE-AS 1174 679 a wet-on-wet process known for the production of plastic-coated prefabricated parts made of concrete, in which on an uncured layer of synthetic resin mortar is applied and the layers, for example, through Shaking are compacted into each other. In this way, layers of ornament and decoration are created in the various designs, but no load-bearing sandwich structure received. The plastic coating here leads to a mixing body in which a hydraulic phase and an organic phase are next to each other tie off. The hydration products of the hydraulic phase lie like islands in the resin mass and affect their advantageous bending and

Asbestzement und einer Beschichtung ist aus dem DE-GM 75 16 513 zu entnehmen. Die Beschichtung kann aus Papier, Kunststoffolie, einem Anstrich, Holzfurnier, Gewebe oder einem Laminat bestehen. Zwischen der Kernschicht und der Beschichtung befindet sich eine Einlage. Diese besteht aus einem mit Kunststoff getränkten Filz oder Vlies. Hierdurch wird die Beschichtung dauerhafter und die Asbestzementplatte weniger brüchig, so daß sie dünner gewählt werden kann. Die Wetterfestigkeit wird erhöhtAsbestos cement and a coating can be found in DE-GM 75 16 513. The coating can consist of paper, plastic film, paint, wood veneer, fabric or a laminate. There is an insert between the core layer and the coating. This consists of a with Plastic soaked felt or fleece. This makes the coating more durable and the asbestos-cement board less brittle, so that it can be chosen thinner. The weather resistance is increased
Eine Schichtverbundplatte aus anorganischen und organischen Schichten, bei der die unterschiedlichen Schichten dauerhaft und kraftübertragend miteinander verbunden sind und damit die guten Eigenschaften eines anorganischen Materials als Kernschicht mit den Vorteilen von Deckschichten aus organischen Kunststoffen ausgewertet werden, scheiterte an den Schwierigkeiten der Verbindung der einzelnen Schichten miteinander. Durch Verleimen und Verkleben konnte kein echter Verbund geschaffen werden. Neben Diffusionsschwierigkeiten treten zwischen Kernschicht und Deckschichten Spannungen auf, die sich naturgemäß nachteilig auswirken. Sowohl die Belastbarkeit als auch die Biegesteifigkeit bekannter Schichtverbundplatten sind unzureichend und lassen nur eine begrenzteA composite sheet made of inorganic and organic layers, in which the different Layers are permanently and force-transmitting connected to one another and thus the good properties of a inorganic material as the core layer with the advantages of outer layers made of organic plastics failed because of the difficulties in connecting the individual layers together. A real bond could not be created by gluing and gluing. Next to Diffusion difficulties arise between the core layer and the outer layers, which naturally arise adversely affect. Both the resilience and the flexural strength of known multilayer composite panels are insufficient and leave only a limited amount
Aufgabe der Erfindung war es, eine Schichtverbundplatte der eingangs genannten Art so auszugestalten, daß sie verbessert und wechselnd dynamisch belastbar ist und eine höhere Biegesteifigkeit aufweistThe object of the invention was to design a layer composite panel of the type mentioned at the outset in such a way that that it is improved and dynamically resilient to changes and has a higher flexural strength
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß zwischen der Kernschicht und der aus Kunststoff bestehenden Deckschicht eine faserbewehrte Zwischenschicht aus ausgehärteten Natur- oder Kunstharzen, die im ungehärteten Zustand wasserverdünnbar sind, vorgesehen istThis object is achieved according to the invention in that between the core layer and from Plastic cover layer is a fiber-reinforced intermediate layer made of cured natural or Synthetic resins, which are water-thinnable in the uncured state, is provided
Durch eine solche Schichtverbundplatte wird eine echte Verbindung zwischen der Kernschicht und der Deckschicht bzw. den Deckschichten geschaffen, da praktisch eine Verwachsung bzw. Verzahnung zwischenSuch a layer composite panel creates a real connection between the core layer and the Cover layer or the cover layers created because there is practically an intergrowth or interlocking between
so den Schichten durch Ausbildung einer sowohl der Kernschicht als auch der Deckschicht zugeordneten Grenzschicht erreicht wird. Das Material der Zwischenschicht wirkt nicht als Klebstoff, sondern es treten Grenzstruktureigenschaften auf, die einen praktisch spannungsfreien Übergang zwischen den Schichten unterschiedlicher Materialien und einen kraftübertragenden Verbund schaffen.thus the layers by forming one assigned to both the core layer and the cover layer Boundary layer is reached. The material of the intermediate layer does not act as an adhesive, but it treads Boundary structure properties that create a practically stress-free transition between the layers different materials and create a force-transmitting bond.
Es wurde gefunden, daß durch die Zwischenschicht eine im Mikrobereich vernetzte Struktur der Grenzflächen erzielt wird, die der Schichtverbundplatte die Eigenschaften eines praktisch einheitlichen Gefüges verleiht. Versuche haben ergeben, daß die Platte tausenden von Wechselbeanspruchungen ausgesetzt werden kann, ohne daß eine Lockerung des Verbundes auftrittIt has been found that the interlayer creates a micro-crosslinked structure of the interfaces is achieved that the multilayer composite panel has the properties of a practically uniform structure confers. Tests have shown that the plate is exposed to thousands of alternating loads can be without loosening of the bond occurs
