Description

Es wurden bereits verschiedene Verfahren und Vorrichtungen angegeben, mit deren Hilfe es gelingt, meist folienförmige thermoplastische Körper mit anderen Materialien mechanisch zu verbinden. Hierbei werden die unterschiedlichen Folien unter gleichzeitiger oder unmittelbar aufeinanderfolgender Einwirkung von Wärme und Druck derartig miteinander verbunden, daß der thermoplastische Stoff sich erweicht und in dieVarious methods and devices have already been specified by means of which it succeeds in mechanically producing mostly film-shaped thermoplastic bodies with other materials associate. Here, the different foils are simultaneously or immediately following one another Exposure to heat and pressure so connected that the thermoplastic material softens and into the

ίο Oberflächenunebenheiten des anderen Stoffes hineinpreßt. ίο presses in surface unevenness of the other fabric.

Bei den neueren dieser Verfahren wird die Erwärmung des Thermoplasten meist auf dielektrischem Wege vorgenommen mit Hilfe eines hochfrequenten elektrischen Wechselfeldes. Als Elektroden dienen vielfach gegeneinanderlaufende Rollen oder Walzen, die gleichzeitig für den notwendigen Preßdruck und für den Vorschub des Materials Sorge tragen.In the newer of these processes, the heating of the thermoplastic is mostly on dielectric Paths made with the help of a high-frequency alternating electric field. As electrodes are often used against rollers or cylinders, which at the same time for the necessary Take care of the pressure and the advance of the material.

In Analogie zur Herstellung des sogenannten Kunstleders lassen sich die obengenannten Verfahren in vielen Anwendungsfällen erfindungsgemäß noch dadurch erweitern, daß, insbesondere bei Herstellung flächenhafter Verbindungen, die mit einem thermoplastischen Stoff zu überziehende Unterlage (Textil, Leder o. dgl.) zunächst mit einer Polyvinylchloridpaste oder -dispersion bestrichen und sodann zwischen zwei gegeneinanderlaufende Rollen- oder Walzenelektroden derartig hindurchbewegt wird, daß durch dielektrische Erwärmung einerseits und mechanische Druckgebung andererseits eine Gelierung der Polyvinyl-In analogy to the production of the so-called artificial leather, the above-mentioned processes can be used in many applications according to the invention by the fact that, especially in Production of planar connections, which are to be covered with a thermoplastic material Base (textile, leather or the like) first coated with a polyvinyl chloride paste or dispersion and then between two counter-rotating roller or roller electrodes of this type is moved through that by dielectric heating on the one hand and mechanical pressure on the other hand, gelation of the polyvinyl

chloridpaste oder -dispersion und gleichzeitig ein mechanisches Verbinden des Thermoplasten mit dem anderen Werkstoff stattfindet.chloride paste or dispersion and at the same time a mechanical connection of the thermoplastic with the other material takes place.

Der Vorteil dieses Verfahrens liegt zunächst darin, daß die Arbeitsgänge des Gelierens und des mechanischen Verbindens unter Einwirkung von Wärme und Druc'k zu einem Arbeitsgang vereinigt werden. Ferner ist die erzielte Verbindung des Thermoplasten mit einem anderen Material wesentlieh intensiver, und es lassen sich sehr dünne thermoplastische Flächenbelegungen von beliebigen Materialien erzielen. Ebenfalls die bei der Herstellung von Kunstleder sich bisher ergebenden Schwierigkeiten, die darin bestanden, daß der mit einem ungelierten pastenförmigen Kunststoff bestrichene Textilträger im Wärmeofen ohne Schädigung des Textilstoffes auf die richtige Geliertemperatur gebracht wird, treten hierbei nicht auf. Der Unterschied des erfindungsgemäßen Verfahrens gegenüber dem der bisher üblichen Herstellung von Kunstleder besteht also im wesentlichen in der sehr wirtschaftlichen Wärmezuführung und der gleichzeitigen Einwirkung von Preßdruck, so daß man erwarten kann, daß die nach dem erfindungsgemäßen Verfahren hergestellten Verbindungen von thermoplastischen mit anderen Stoffen wesentlich haltbarer und intensiver sein werden.The advantage of this process is first of all that the operations of gelling and mechanical connection under the action of heat and pressure combined into one operation will. Furthermore, the bond achieved between the thermoplastic and another material is essential more intense, and very thin thermoplastic surface coverings of any Achieve materials. Also those that have arisen so far in the manufacture of artificial leather Difficulties that consisted in the fact that the coated with an ungelled pasty plastic Textile carrier in the heating oven to the correct setting temperature without damaging the textile material is brought, do not occur here. The difference of the method according to the invention compared to the production of artificial leather that has been customary up to now essentially consists in the very economic heat supply and the simultaneous action of pressing pressure, so that one can expect that the compounds prepared by the process of the invention of thermoplastics with other materials will be much more durable and intense.

Falls stärkere Belegungen erwünscht sind, ist das beschriebene erfindungsgemäße Verfahren wiederholt anzuwenden. Es lassen sich auch sehr gut doppelseitige Belegungen herstellen.If stronger occupancies are desired, the described method according to the invention is repeated apply. Double-sided assignments can also be produced very well.

Textilstoffe können nach diesem Verfahren beispielsweise dadurch wasserundurchlässig gemacht werden, daß sie vor Anwendung des Verfahrens in einer relativ dünnflüssigen Polyvinylchloridpaste getränkt werden.Textiles can be made water-impermeable by this method, for example be that before using the method in a relatively thin polyvinyl chloride paste to be soaked.
