These plates are made in such a way that the light building board in a simple manner with the corresponding natural stone slab a liquid 2-component adhesive with the help of a fabric layer glued together.
Dieses Verfahren ist insofern zeitaufwendig, als die verwendeten Klebersysteme bei Raumtemperatur aushärten und eine entsprechend lange Aushärtungszeit benötigen.This method is time consuming in that the ones used Cure adhesive systems at room temperature and a correspondingly long one Need curing time.
Ein weiterer Nachteil besteht darin, daß die Kleber niedermolekulare Bestandteile, die einen niedrigen Dampfdruck aufweisen, enthalten. Die entweichenden Dämpfe stellen erhebliche Geruchs- und Gesundheitsbelastungen dar, so daß man besondere Vorrichtungen, wie Abzüge, vorsehen muß. Dieses Verfahren erfordert außerdem für den Kleber eine besondere Mischvorrichtung, mit der das notwendige Mischungsverhältnis der Kleberkomponenten eingestellt und das Klebersystem gut vermischt und gleichmäßig auf die zu verklebende Fläche aufgetragen werden kann.Another disadvantage is that the glue is low molecular weight Contain components that have a low vapor pressure. The escaping vapors pose significant odor and Health problems, so that special devices such as deductions, must provide. This procedure also requires one for the adhesive special mixing device with which the necessary mixing ratio of the adhesive components set and the adhesive system mixed well and can be applied evenly to the surface to be glued.
Man muß natürlich bestrebt sein, den Aufwand für die Herstellung möglichst gering zu halten. Das kann natürlich nur bedeuten, daß man auf die oben geschilderten Prozeduren ganz oder teilweise verzichtet.Of course, one must strive to make the effort for the production as possible to keep low. Of course, this can only mean that you are on the above described procedures completely or partially waived.
Es wurde daher mit dem erfindungsgemäßen Verfahren eine Möglichkeit geschaffen, die die mit den bisherigen Verfahren verbundenen Nachteile überwindet.The method according to the invention therefore became a possibility created the disadvantages associated with previous methods overcomes.
Gegenstand der vorliegenden Erfindung ist somit ein gegenüber den bisherigen Verfahren vereinfachtes Verfahren zur Herstellung von Naturstein-Leichtbauplatten.The object of the present invention is thus compared to previous process simplified process for the production of Natural stone lightweight panels.
Das Verfahren ist dadurch gekennzeichnet, daß man auf eine Leichtträger platte einseitig oder beidseitig eine Klebefolie (Prepreg) aufbringt und daß man das so erhaltene System mit einer Natursteinplatte bei höherer Temperatur und Druck verbindet.The method is characterized in that on a light carrier apply an adhesive film (prepreg) on one or both sides and that the system thus obtained with a natural stone slab at higher Combines temperature and pressure.
Nach dem erfindungsgemäßen Verfahren lassen sich Naturstein-Leichtträger platten herstellen, ohne daß dabei Nachteile insbesondere der oben beschriebenen Art auftreten.Natural stone lightweight carriers can be made using the method according to the invention produce plates without disadvantages in particular the above described type occur.
Das erfindungsgemäße Verfahren kann auf zweierlei Weise durchgeführt werden.The method according to the invention can be carried out in two ways will.
- 1. Man geht so vor, daß man von einer Natursteinplatte ausgeht, die eine Stärke von 20 bis 30 mm aufweist, daß man die Platte beidseitig mit Leicht trägerplatten versieht, indem man auf diese eine Klebefolie (Prepreg) aufbringt und die Naturstein-Leichtbauplatte erhält, indem man die Natur steinplatte des so erhaltenen Verbundsystems in Längsrichtung mittig zersägt und kalibriert.1. You proceed from a natural stone slab, the one Thickness of 20 to 30 mm shows that the plate is light on both sides provides support plates by placing an adhesive film (prepreg) on them applies and maintains the natural stone lightweight board by preserving nature stone slab of the composite system thus obtained in the longitudinal center sawn and calibrated.
- 2. Man geht so vor, daß man von einer Natursteinplatte ausgeht, diese mit einer Leichtträgerplatte einseitig verklebt, indem man auf die Leicht trägerplatte eine Klebefolie (Prepreg) aufbringt, diese auf die Naturstein platte auflegt und das so erhaltene Verbundsystem miteinander verklebt und anschließend kalibriert.2. You proceed from a natural stone slab, this glued on one side with a light carrier plate by clicking on the light carrier plate applies an adhesive film (prepreg) to the natural stone puts on the plate and the resulting composite system glued together and then calibrated.

Bei der ersten Verfahrensvariante muß man naturgemäß von einer Mindest stärke der Natursteinplatte ausgehen, die gestattet, daß man die Verbund platte in Längsrichtung mittig zersägen kann.In the first variant of the process one naturally has to have a minimum Strength of the natural stone slab that allows the composite can saw the middle of the plate in the longitudinal direction.
Bei der zweiten Verfahrensvariante geht man von einer Natursteinplatte aus, die gegenüber der Stärke der Natursteinplatte der ersten Verfahrens variante eine geringere Stärke aufweist. Diese Stärke muß gestatten, daß die Handhabung des Herstellungsvorganges der Platte ohne Bruchgefahr möglich und die gewünschte Endstärke der Platte ohne großen Aufwand erreicht werden kann.The second method variant is based on a natural stone slab out, compared to the strength of the natural stone slab of the first method variant has a lower strength. This strength must allow that the handling of the manufacturing process of the plate without risk of breakage possible and the desired final thickness of the plate without much effort can be reached.
Die Stärke der Natursteinplatte beträgt bei der ersten Verfahrensvariante 20 bis 30 mm und bei der zweiten Verfahrensvariante mindestens 10 mm. Das Leichtträgermaterial in Form einer Platte kann ein Hohlkörper sein, eine Wabenkern-Platte oder ein Rost oder ein raumausfüllender Hartschaum stoff.The thickness of the natural stone slab is in the first process variant 20 to 30 mm and in the second process variant at least 10 mm. The light carrier material in the form of a plate can be a hollow body, a honeycomb core plate or a grate or a space-filling hard foam material.
Das Leichtträgermaterial besteht aus Aluminium oder aus einem Kunststoff. Als Kunststoffe kommen in Betracht Hartschaumstoffe aus Polystyrol und Polyurethan.The light carrier material consists of aluminum or a plastic. Rigid foams made of polystyrene and Polyurethane.
Der für das Leichtträgermaterial verwendete Kleber ist ein reaktives Kleber-System. Das Klebersystem ist ein 1-Komponenten-Epoxidharz-System oder Phenolharz-System.The adhesive used for the light carrier material is a reactive one Glue system. The adhesive system is a 1-component epoxy resin system or phenolic resin system.
