Description

Vorrichtung zur Herstellung von Kunststoffplatten Die Neuerung betrifft eine Vorrichtung zur Herstellung von KunststoffplaLten, insbesondere aus weichmacherfreiem Polyvinylclorid, die zwei einander mit ihren Breitschlitzdüsen gegenüberstehende Extruder besitzt, zwischen deren Breitschlitzdüsen in Vorschubrichtung der aus ihnen ausgetretenen Kunststoffmassen eine Armierang zuführbar ist. Device for the production of plastic sheets The innovation concerns a device for the production of plastic sheets, in particular from plasticizer-free Polyvinyl chloride, the two facing each other with their slot nozzles Extruder has, between their slot dies in the direction of advance of them a reinforcement can be fed to leaked plastic masses.

Der Neuerung liegt die Aufgabe zugrunde, die bekannten Vorrichtungen der sie betreffenden Art weiter zu entwickeln und zu verbessern.The innovation is based on the task of the known devices of the kind that concern them further to develop and improve.

Als ein nachteil bei den bekannten Vorrichtungen hat sich herausgestellt, daß die aus den Breitschlitzdüsen der Extruder austretenden Kunststoffmassen leicht entgegen der Vorschubrichtung aus dem Spalt zwischen den Breitschlitzdüsen austreten können. Ein weiterer Nachteil der bekannten Vorrichtungen besteht darin, daß die Armierung von den plastischen Massen nicht sehr gleichmäßig durch- tränkt wird. Diese Nachteile sollen durch die Neuerung behoben wer- den. A disadvantage of the known devices has been found to be that the plastic masses emerging from the slot dies of the extruder can easily emerge from the gap between the slot dies counter to the feed direction. Another disadvantage of the known devices is that the reinforcement is not very evenly penetrated by the plastic masses. is soaked. These disadvantages should be eliminated by the innovation the.

Die Neuerung besteht darin, daß in Vorschubrichtung des armierten Kunststoffbandes unmittelbar vor den Breitschlitzdiisen Kühlvorrich- tungen beiderseits der zwischen die Breitschlitzdüsen einzuführenden tD Armierung und hinter den Breit. schlitzdüsen beiderseits des Kunst- stoffbandes je eine Vacuumeinrichtung vorgesehen ist.The innovation consists in the fact that in the feed direction of the reinforced plastic belt, cooling devices are installed directly in front of the slot lines on both sides of the to be introduced between the slot nozzles tD Reinforcement and behind the broad. slot nozzles on both sides of the art fabric tape is provided a vacuum device.

Durch die Neuerung wird einerseits der wesentliche Vorteil erreicht, daß das plastische Material nicht entgegen der Vorschubrichtung aus dem Spalt zwischen den Breitschlitzdüsen austreten kann und andererseits, daß die Armierung von den thermoplastischen Massen besonders gleichmäßig durchtränkt wird.On the one hand, the innovation achieves the essential advantage, that the plastic material is not against the direction of advance from the gap between the slot nozzles can escape and on the other hand that the reinforcement of the thermoplastic mass is soaked particularly evenly.

Bei einem weiteren Vorschlag der Neuerung ist vorgesehen, daß mehrere-beispielsweise zwei-Armierungen zur Zuführung zwischen die beiden Breitschlitzdüsen vorgesehen sind.Another suggestion of the innovation provides that several, for example two reinforcements intended for feeding between the two slot nozzles are.

Hierdurch wird es ermöglicht, beispielsweise Verbundplatten mit einer schlecht durchlässigen Armierung aus Asbestzement und einer oder mehreren weiteren Armierungen, beispielsweise aus Maschendraht, herzustellen.This makes it possible, for example, composite panels with a poorly permeable reinforcement made of asbestos cement and one or more others Manufacture reinforcements, for example from wire mesh.

In Figur 1 ist eine erste Ausführungsform und in Figur 2 eine zweite Ausführungsform der erfindungsgemäßen Vorrichtungen dargestellt.In Figure 1 is a first embodiment and in Figure 2 is a second Embodiment of the devices according to the invention shown.

Bei der ersten Ausführungsform gem. Figur l stehen sich zwei Extruder 10,11 mit ihren Breitschlitzdüsen 12,13 einander gegenüber. Die Extruder 10,11 können eine gleiche oder verschiedene Stundendurchsatzleistung besitzen. Eine Armierung 14, beispielsweise Maschendraht, wird von einer Rol : le 15 abgewickelt und den Kunststoffmassen bei ihrem kontinuierlichen Austritt aus den Breitschlitzdüsen 12,13 fortlaufend in Richtung Pfeil A zugeführt und zwar derart, daß die Armierung zwischen die beiden aus den Düsen 12,13 austretenden Kunststoffmassen gelangt und so, von diesen eingebettet, eine innige Verbindung mit den Kunststoffmassen eingeht. s'entsteht ein einheitlich fortlaufendes armiertes Kunststbffband 16, beispielsweise von 1 m Breite und einer Wanddicke von 2 mm. Das armierte Kunststoffband wird bekannterweise über Glätt-und Kühlaggregat 17 zu einem Abzugsaggregat 18 geführt, die auf einem Zwischenboden 22 oberhalb des einen Extruders 11 angeordnet sein können.In the first embodiment according to FIG 10,11 with their slot nozzles 12,13 opposite each other. The extruders 10, 11 can have the same or different hourly throughput. Reinforcement 14, for example wire mesh, is unwound from a Rol: le 15 and the Plastic masses as they continuously emerge from the slot nozzles 12, 13 continuously fed in the direction of arrow A in such a way that the reinforcement between the two plastic masses emerging from the nozzles 12, 13 arrives and so, of embedded in this, enters into an intimate connection with the plastic masses. s' arises a uniformly continuous reinforced plastic tape 16, for example from FIG m width and a wall thickness of 2 mm. The reinforced plastic tape is known via smoothing and cooling unit 17 to a take-off unit 18, which on a Intermediate floor 22 can be arranged above one extruder 11.

Zwischen dem Glätt-und Kühlaggregat 17 und dem Abzugsaggregat 18 kann eine Onduliervorrichtung 19 zwischengeschaltet sein, wodurch ein iellplattenband erzeugt werden kann.Between the smoothing and cooling unit 17 and the take-off unit 18th A curling device 19 can be interposed, whereby an elliptical plate conveyor can be generated.

Die Armierung 14 wird zusammen mit dem thermoplastischen Material von den Breitschlitzdüsen 12,13 abgezogen. Mit Vorteil wird die Kunststoffmasse unmittelbar nach Zuführung der Armierung einem Vacuum ausgesetzt. Hierdurch wird erreicht, daß die Armierung von der thermoplastischen hasse besonders gleichmäßig durchtränkt wird. Zu diesem Zweck ist in Vorschubrichtung des armierten Kunststoffbandes 16 beiderseits desselben hinter den Breitschlitzdüsen 12,13 je eine Vacuumeinrichtung 20,20a vorgesehen. mit Vorteil sind weiter in Vorschubrichtung Pfeil A des armierten Kunststoffbandes 16 unmittelbar vor den Breitschlitzdüsen 12,13 Kühlvorrichtungen 21,21a beiderseits der zwischen die Breitschlitzdüsen 12,13 einzuführenden Armierung 14 vorgesehen. Hierdurch wird erreicht, daß das thermoplastische liaterial, das entgegen der Vorschubrichtung in die Armierung hineingedrückt wird, rasch durch Abkühlen erstarrt, sodaß es nicht entgegen der Vorschubrichtung aus dem Spalt zwischen Breitschlitzdüsen 12,13 austreten kann. The reinforcement 14 is removed from the slot nozzles 12, 13 together with the thermoplastic material. The plastic compound is advantageously exposed to a vacuum immediately after the reinforcement has been supplied. This ensures that the reinforcement is soaked particularly evenly by the thermoplastic hate. For this purpose, a vacuum device 20, 20a is provided on both sides of the same behind the slot nozzles 12, 13 in the feed direction of the reinforced plastic strip 16. Advantageously, further in the feed direction arrow A of the reinforced plastic strip 16 directly in front of the slot nozzles 12, 13 cooling devices 21, 21 a are provided on both sides of the reinforcement 14 to be inserted between the slot nozzles 12, 13. This ensures that the thermoplastic limaterial, which is pressed into the reinforcement against the direction of advance, rapidly solidifies as a result of cooling, so that it does not counteract the direction of advance emerge from the gap between slot nozzles 12,13 can.

Bei der zweiten Ausführungsform gem. Figur 2 sind zwei Extruder 23, 24 derart einander gegenüberstehend angeordnet, daß ihre Achsen 25,26 jeweils einen spitzen Winkel von beispielsweise 20 0 mit der Vorschubrichtung Pfeil A des armierten Kunststoffbandes 16 bilden, sodaß diese beim Austritt aus den Breitschlitzdüsen 12,13 nur wenig umgelenkt zu werden brauchen. Bei dieser Ausführungsform werden als Extruder 23,24 Ginschneckenextruder, die ein konisch ausgebildetes 8chneckenende haben, eingesetzt. Die konischen ocuneckenenden 23a, 24a reichen weit in die langen Konusse der Extrudergehäuse hinein. Hierdurch wird ein gutes Auspressen der Kunststoffmassen aus den Düsen erzielt. s ist mit der neuerungsgemäßen Vorrichtung möglich, zwei verschiedene Kunststoffe oder Kunststoffmischungen mit einer zu versehen. hierdurch wird es ermöglicht, Verbundplatten zu erzeugen. Wenn z. B. eine nur schlecht durchtränkbare Armierung, wie etwa Asbestpapier, gewählt wird, so ist mit einer i. iischung der aus den Extrudern 10,11 bzw. 23, 24 austretenden verschiedenen Materialien nicht zu rechnen.In the second embodiment according to FIG. 2, two extruders 23, 24 arranged opposite one another in such a way that their axes 25,26 each have one acute angle of, for example, 20 0 with the feed direction arrow A of the armored Form plastic band 16 so that it exits the slot nozzle 12,13 only need to be deflected a little. In this embodiment as an extruder 23,24 Gin screw extruder, which has a conical 8 screw end have used. The conical ocun corner ends 23a, 24a extend far into the long ones Cones of the extruder housing into it. This ensures that the plastic masses are pressed out well obtained from the nozzles. s is possible with the device according to the innovation, two different plastics or plastic mixtures with one to Mistake. this makes it possible to produce composite panels. If z. Legs only poorly impregnable reinforcement, such as asbestos paper, is chosen, so is with an i. Mixing of the various exiting from the extruders 10, 11 and 23, 24 Materials not to be expected.

Es erfolgt jedoch eine thermische Verschweißung der beiden verschiedenen Kunststoffabmischungen an der Grenzschicht im Asbestpapier und beiderseits desselben. Hierdurch wird es beispielsweise möglich, PVC-Wellplatten flir Bedachungsplatten zu erzeugen, die auf der Wetterseite aus einem mit größeren Mengen verschiedenartiger Füllstoffe versetzten PVC bestehen. Die geringe mechanische Festigkeit, die gerade eine derartige PVC-Abmischung zeigt, kann nicht nur durch die Armierung allein, sondern auch durch das aus dem anderen Extruder zugeführte Material ausgeglichen werden, das die Unterseite der. Wellplatte bildet und folglich nicht wetterfest zu sein braucht. Es ist auch ohne weiteres möglich, Platten herzustellen, die eine dünne Oberseite aus sehr wetterfestem PVC und eine dickere Unterseite aus einem anderen thermoplastischen Material, wie z. B. Polyäthylen oder Polypropylen aufweisen. Es wird so eine Verbundplatte erzeugt mit verschiedenen Eigenschaften auf beiden Seiten mit Hilfe einer schlecht durchtränkbaren Armierung. kerner sieht eine Weiterentwicklung der Neuerung vor, daß die Kunststoffmasse mit einer Armierung aus zwei verschiedenen Materialien versehen wird. Es ist so möglich, Verbundplatten mit einer schlecht durchlässigen Armierung, beispielsweise aus Asbestpapier, wie vorher beschrieben, herzustellen, indem das Asbestpapier als Trennschicht für die beiden verschiedenartigen Kunststoffe wirkt, wobei zusätzlich noch eine Armierung 14a durch eine oder mehrere Lagen Maschendraht erfolgt. Diese können von einer oder mehreren Rollen 27 unterhalb der Rolle 15 abgewickelt werden. Die zusätzlich von der Rolle 27 abzuziehende Armierung 14a kann naturgemäß mit einer von der Rolle 15 abzuziehenden Armierung 14 aus beliebigem gleichen oder anderen Material kombiniert werden.However, the two different ones are thermally welded together Plastic mixtures at the boundary layer in the asbestos paper and on both sides of the same. This makes it possible, for example, to use corrugated PVC sheets for roofing sheets to produce that on the weather side from one with larger amounts of different types Fillers are made of PVC. The low mechanical strength that straight such a PVC blend shows, can not only through the reinforcement alone, but also compensated for by the material fed in from the other extruder that will be the bottom of the. Corrugated sheet forms and therefore not weatherproof needs to be. It is also easily possible to produce plates that have a thin top made of very weatherproof PVC and a thicker bottom made of one other thermoplastic material, such as B. have polyethylene or polypropylene. This creates a composite panel with different properties on both Sides with the help of poorly impregnable reinforcement. kerner sees a further development the innovation that the plastic compound with a reinforcement of two different Materials is provided. It is thus possible to have composite panels with a bad permeable reinforcement, for example made of asbestos paper, as described above, Manufacture by using the asbestos paper as a separation layer for the two different types Plastics acts, with an additional reinforcement 14a by one or more Layers of wire mesh are made. These can be supported by one or more rollers 27 below the roll 15 are unwound. The reinforcement to be removed from the roll 27 14a can of course be made of any type of reinforcement 14 to be pulled off the roll 15 same or different material can be combined.
