Abstract

A process and a device suitable for carrying out the process are presented for the continuous production of a marbled thermoplastic material web. This object is achieved by the metering of granules differing in colour from the base material into an already molten base material. The granules are fused by the hot base material, mixed therewith during an extrusion process and shaped in a die to form a strand or a web. The plastic granules produce a marbling effect in the melted base material on account of the shaping process.

Description

Verfahren und Einrichtung zur Herstellung marmorierter Bahnen aus thermoplastischen- Kunststoffen oder Kautschuk Die Erfindung betrifft ein Verfahren gem. Anspruch 1 und eine Vorrichtung gemäß des Anspruchs 4.Process and device for the production of marbled sheets thermoplastics or rubber The invention relates to a method according to claim 1 and a device according to claim 4.

Aus der DE-AS 1167 516 ist ein Verfahren und eine Vorrichtung zur Herstellung marmorierter Platten oder Bahnen bekannt.From DE-AS 1167 516 a method and a device for Manufacture of marbled panels or sheets known.

Rohplatten werden erwärmt und nach dem Aufeinanderlegen in Streifen aufgetrennt. Die Streifen werden als gefaltete Pakete zur gründlichen Durchsetzung auf ein Riffelwalzwerk gegeben, wobei ein- oder mehrere Durchgänge vorgesehen werden können.Raw panels are heated and, after being laid on top of one another, in strips separated. The strips come as folded packages for thorough enforcement placed on a corrugating mill, with one or more passages being provided can.

Es ist offensichtlich, daß ein derartiges Verfahren äußerst aufwendig und personalintensiv ist und daher als unwirtschaftlich bezeichnet werden muß.It is obvious that such a process is extremely laborious and is labor-intensive and must therefore be described as uneconomical.

Aus der DE-OS 14 79 605 ist ebenfalls ein Verfahren und ein Kalander bekannt, zur Herstellung marmorierter Materialbahnen. Es werden verschieden eingefärbte Kunststoffmischungen einem oberen und unteren Walzenspalt eines 6-Walzen-Kalanders zugeführt, die danach jeweils einen weiteren Arbeitsspalt durchlaufen und in einem mittleren Walzenspalt zu einer aus zwei verschiedenfarbige Mischungen bestehenden marmorierten Materialbahn miteinander vereinigt werden.From DE-OS 14 79 605 is also a method and a calender known for the production of marbled material webs. There are different colored Plastic mixtures in an upper and lower nip of a 6-roll calender fed, which then each pass through a further working gap and in one middle nip to one consisting of two different colored mixtures marbled web of material are combined with one another.

Aus 6 WaLzen bestehende Kalander erfordern sehr hohe Kapitalinvestitionen, so daß sich dieses Verfahren allein aus diesem Grund in- der Praxis nicht durchgesetzt hat.Calenders consisting of 6 rolls require very high capital investments, so that for this reason alone this procedure has not been implemented in practice Has.

Es ist die Aufgabe der vorliegenden Erfindung ein Verfahren und eine für die Durchführung des Verfahrens geeignete Einrichtung aufzuzeigen zur Herstellung von marmorierten Bahnen aus thermoplastischen Materialien.It is the object of the present invention to provide a method and a to indicate suitable facilities for the implementation of the process for the production of marbled sheets made of thermoplastic materials.

Die Aufgabe wird gelöst durch die kennzeichnenden Merkmale der Verfahrensansprüche.The object is achieved by the characterizing features of the method claims.

Eine bevorzugte, für die Durchführung des Verfahrens geeignete Einrichtung, wird in den Einrichtungsansprüchen gekennzeichnet.A preferred facility suitable for carrying out the procedure, is characterized in the furnishing claims.

Da das vom Grundmaterial sich farblich unterscheidende Granulat in das aufgeschmolzene, bereits eine Temperatur je nach Material bis 1500 C aufweisende Grundmaterial eindosiert wird, überträgt sich die Temperatur der Schmelze auf das Granulat. Das Granulat weist beim Zudosieren etwas Raumtemperatur auf. Es erfolgt ein langsames Anschmelzen der Granulate im Verlauf des Fördervorganges zur Austrittsöffnung, Hervorgehoben werden muß, daß die für den Anschmelzvorgang des Granulates erforderliche Wärmeenergie eingespart wird. Das eindosierte Granulat braucht nicht vorgeheizt zu werden.Since the color of the granulate differs from the base material in the melted one, which has a temperature of up to 1500 C depending on the material Base material is metered in, the temperature of the melt is transferred to the Granules. When added, the granulate is somewhat at room temperature. It takes place a slow melting of the granules in the course of the conveying process to the outlet opening, It must be emphasized that the required for the melting process of the granules Thermal energy is saved. The dosed granulate does not need to be preheated to become.

Durch das Anschmelzen der Granulate wird sichergestellt, daß eine gute Verbindung zum Grundmaterial hergestellt wird.The melting of the granules ensures that a a good connection to the base material is established.

Beim Ausdüsen des mit dem Grundmaterial vermischten, etwa zur Hälfte geschmolzenen Granulates aus der Breitschlitzdüse zu einer Bahn, ergibt sich eine Musterung, die etwa der Musterung des Naturmarmors entspricht.When spraying out the mixed with the base material, about half melted granules from the slot die to form a web, the result is a Pattern that roughly corresponds to the pattern of natural marble.

Der Ausformvorgang kann unterstützt werden durch ein Hindurchlaufenlassen der Bahn durch einen Walzenspalt eines 2-Walzen-Kalanders. Wenn die Dicke des Walzenspalts geringfügig kleiner ist als die Dicke der aus der Breitschlitzdüse austretende Materialbahn, bildet sich ein rollender Knet, in dem erwärmte Granulate weiter vermischt werden. Im Walzenspalt erfolgt#eine Verformung der erwärmten Granulate und es ergibt sich in Verbindung mit dem plastischen Grundmaterial ein Marmor iereffekt.The molding process can be supported by allowing it to pass through the web through a nip of a 2-roll calender. When the thickness of the nip is slightly smaller than the thickness of the material web emerging from the slot nozzle, A rolling knead is formed in which the heated granules are further mixed. In the nip, the heated granules are deformed and this results In connection with the plastic base material a marble effect.

Eine für die Durchführung des Verfahrens besonders geeignete Einrichtung wird in den Ansprüchen 4 und 5 beansprucht und weist einen senkrecht angeordneten Aufschmelzextruder auf. Die senkrechte Anordnung sichert einen guten Materialeinzug in den Einfüllteil des Extruders.A facility particularly suitable for carrying out the procedure is claimed in claims 4 and 5 and has a vertically arranged Melting extruder on. The vertical arrangement ensures good material intake into the feed part of the extruder.

Das aufgeschmolzene Material wird in einen waagerecht dazu angeordneten Austragsextruder übergeben unter gleich zeitiger Zudosierung des andersfarbigen Granulates in die dafür vorgesehene Einfüllöffnung.The melted material is arranged in a horizontal line Discharge extruder transfer with simultaneous metering of the different color Granulate in the opening provided for this purpose.

Mittels des erfindungsgemäßen Verfahrens ist es somit möglich, auf eine sehr einfache Weise und mittels einer sehr preisgünstigen Maschineneinrichtung, kontinuierlich eine marmorierte Bahn herzustellen, wobei insbesondere der Energieaufwand für das Aufheizen des Granulates entfällt. Es ist lediglich eine weitere Einfüllöffnung in dem Austragsextruder mit einer dieser zugeordneten Dosier einrichtung zusätzlich erforderlich, um anstelle einer einfarbigen Materialbahn eine marmorierte Materialbahn herzustellen, wobei hervorgehoben werden muß, daß ein sehr natürlicher Marmor iereffekt erzielt wird.By means of the method according to the invention, it is thus possible to a very simple way and by means of a very inexpensive machine set-up, continuously to produce a marbled sheet, with particular the energy consumption there is no need to heat the granulate. It's just another filler opening in the discharge extruder with a metering device assigned to it required to use a marbled material web instead of a single-colored material web to produce, whereby it must be emphasized that a very natural marble effect is achieved.

Die Erfindung wird anhand einer Zeichnung näher erläutert. Es zeigen: Fig. 1 eine Einrichtung zur Durchführung des Mamorierverfahrens im Längsschnitt Fig. 2 einen Schnitt II - II durch die Einrichtung gem. Fig. 1 Fig. 3 einen Schnitt III - III gem. Fig. 1 Die in Fig. 1 gezeigte Einrichtung besteht aus dem Aufschmelzextruder 1 und dem Austragsextruder 2. Im Aufschmelzextruder 1 ist die Schnecke 3 angeordnet, die mittels Antriebseinheit 4 in Drehbewegung gesetzt wird und sowohl oben in Lager 5 als auch unten in der Antriebs einheit 4 gelagert ist.The invention is explained in more detail with reference to a drawing. Show it: 1 shows a device for carrying out the marbling process in longitudinal section Fig. 2 shows a section II - II through the device according to Fig. 1 Fig. 3 shows a section III - III according to Fig. 1 The device shown in Fig. 1 consists of the melting extruder 1 and the discharge extruder 2. The screw 3 is arranged in the melting extruder 1, which is set in rotary motion by means of the drive unit 4 and in bearings at the top 5 as well as below in the drive unit 4 is stored.

Dosiereinrichtung- 6 fördert Material in den Einfülltrichter 7, welches nach dem Aufschmelz- und Homogenisier vorgang im Aufschmelzextruder 1 durch die Verbindungsöffnung 8 in den Austragsextruder 2 gelangt.Dosing device- 6 conveys material into the hopper 7, which after the melting and homogenizing process in the melting extruder 1 through the Connection opening 8 reaches the discharge extruder 2.

Austragsextruder 2 weist eine Austragsschnecke 9 auf, die tief geschnittene Gänge 10 aufweist, für den Transport des aufgeschmolzenen und homogenisierten Materials.Discharge extruder 2 has a discharge screw 9, the deeply cut Has aisles 10, for the transport of the melted and homogenized material.

Durch eine etwa eine Temperatur von 1600C aufweisende PVC-Schmelze wird das mit Raumtemperatur dem Austragsextruder 2 zudosierte Granulat an den Oberflächen angeschmolzen und durch Schnecke 9 einem Werkzeug 13 zugeführt.By means of a PVC melt at a temperature of around 1600C the granules metered into the discharge extruder 2 at room temperature are on the surfaces melted and fed to a tool 13 by screw 9.

Der Austrittsspalt 14 des Werkzeuges 13 mündet bei dem gezeigten Ausführungsbeispiel in einen Wälzenspalt 15 zwischen den Walzen 16. In dem Walzenspalt erfahren die mittlerweile plastischen Granulate eine längliche Verformung, so daß sich ein sehr naturgetreuer Marmoriereffekt ergibt.The exit gap 14 of the tool 13 opens in the embodiment shown in a roller gap 15 between the rollers 16. In the roller gap, the experience meanwhile plastic granules an elongated deformation, so that a very lifelike marbling effect results.

Der Marmoriereffekt kann gezielt beeinflußt werden, wenn der Walzensplat 15 geringfügig kleiner in seiner Dicke eingestellt wird als die Dicke der aus der Breitschlitzdüse 13 austretende Materialbahn. Es bildet sich dann ein kleiner rotierender Materialknet vor dem Spalt 15 aus, aufgrund dessen ein besonders langgezogenes Marmor ierungsmuster erhalten wird.The marbling effect can be specifically influenced if the roll splat 15 is set slightly smaller in its thickness than the thickness of the Wide slot nozzle 13 exiting material web. A small rotating one then forms Kneading material in front of the gap 15, due to which a particularly elongated marble ation pattern is obtained.
