Eine Möglichkeit, die Aluminiumfolien als Deckschichten mit der Kernschicht aus PVC zu verbinden, besteht beispielsweise in der Anwendung eines Klebers. Vorteilhaft wird dabei ein wärmeaktivierbarer Kleber verwendet.In a further development of the composite material it is provided that this is preferred high quality anodized aluminum foils are used for the cover layers, whereby the thickness of such aluminum foils is preferably about 100%. A possibility, to connect the aluminum foils as cover layers with the core layer made of PVC, consists for example in the application of an adhesive. It is advantageous to have a heat activated adhesive used.
Je nach der gewünschten Dicke des Yerbundmaterials kann die Kernschicht aus einer oder mehreren Folien, vorzugsweise aus PVC-Eartfolien, bestehen. Hierbei werden bevorzugt Folien einer Dicke von 0,3 bis 0,8 mm verwendet. Die Folien für die Kernschicht können einheitlich in einer Farbe oder aber auch in unterschiedlichen Farben gefärbt werden. Je nach der Tiefe der Gravur ist es dann möglich, ein Schriftbil4 in verschiedenen Farben za erhalten.Depending on the desired thickness of the composite material, the core layer consist of one or more foils, preferably PVC ear foils. Here foils with a thickness of 0.3 to 0.8 mm are preferably used. The slides for the core layer can be uniform in one color or in different Colors to be colored. Depending on the depth of the engraving, it is then possible to create a font image received in different colors za.
Ein Verfahren zum Herstellen eines plattenförmigen geschichteten Verbundmaterials besteht darin, daß die Alu:n-iniumfolien für die-Deckschichten bei kontinuierlichem Ablauf von Rollen zunächst auf der Rückseite mit einem wärmeaktivierbaren Kleber beschichtet und dann entsprechend der gewünschten Formatgröße zu Tafeln abgeiängt werden.A method of manufacturing a plate-shaped laminated composite material consists in the fact that the aluminum: n-inium foils for the top layers with continuous Sequence of roles initially on the Back with a heat-activated Adhesive coated and then cut into panels according to the desired format size will.
Für die Kernschicht werden farbige Kalanderfolien, z.B. aus PVC-Hart, verwendet, die ebenfalls zu entsprechenden Formaten abgelängt werden. For the core layer, colored calender foils, e.g. made of rigid PVC, are used are used, which are also cut to the appropriate formats.
Aus den Aluminiumfolien und den Kalanderfolien wird dann ein Preßpaket aufgebaut, dessen untere und obere Deckschicht je aus einer 'Kleberbeschichteten Aluminiumfolie besteht sowie einer entsprechenden Anzahl von einer oder mehreren Tafeln aus Kunststoffolie als Kernschicht. A press pack is then made from the aluminum foils and the calender foils constructed, its lower and upper cover layer each from an 'adhesive-coated There is aluminum foil and a corresponding number of one or more Sheets made of plastic film as the core layer.
Dieses Preßpaket wird dann in einer Etagenpresse bei vorzugsweise 160 bis 170°C verpreßt, bie dieser Temperatur wird der Kleber aktiviert und erzeugt eine haftfeste Verbindung zwischen den Kalanderfolien und den Aluminiumdeckschichten, während die einzelnen Kalanderfolien, z.B.This press pack is then in a multi-stage press at preferably 160 to 170 ° C pressed, at this temperature the adhesive is activated and produced a firm connection between the calender foils and the aluminum cover layers, while the individual calender films, e.g.
aus PVC, sich bei diesen Temperaturen im plastischen Bereich untereinander verbinden. made of PVC, at these temperatures in the plastic range with each other associate.
