Description

Verfahren zur kontinuierlichen Herstellung von Uberzügen aus festen elastischen Schaumstoffen Zusatz zum Patent 839 092 Das Patent 839092 betrifft ein Verfahren zur kontinuierlichen Herstellung von festen elastischen Schaumstoffen, z. B. aus Polyvinylchlorid oder natürlichem oder künstlichem Kautschuk, bei dem das noch plastische Material nach der Zersetzung des Treibmittels in einem unter Druck stehenden Raum, der mit Wasser oder einer anderen Flüssigkeit, Stickstoff oder einem anderen Gas, gefüllt ist, gefördert wird und im Druck so lange verweilt, bis die Erstarrung oder elastische Verfestigung eingetreten ist. Der noch plastische Schaumstoff kann beispielsweise nach Verlassen des Mundstückes einer Spritzmaschine mit einer Schicht von Gummi, Kautschuk, plastischen Kunststoffen u. dlgl. umspritzt werden.Process for the continuous production of coatings from solid elastic foams additive to patent 839 092 The patent 839092 relates to a Process for the continuous production of solid elastic foams, z. B. made of polyvinyl chloride or natural or synthetic rubber, in which the still plastic material after the decomposition of the propellant in one under Pressurized space filled with water or another liquid, nitrogen or another gas, is filled, is conveyed and remains in the pressure as long as until solidification or elastic solidification has occurred. The still plastic one Foam can, for example, after leaving the mouthpiece of an injection molding machine with a layer of rubber, caoutchouc, plastic plastics and the like. encapsulated will.

Es wurde nun gefunden, daß man hei Ausführung des Verfahrens des genannten Patents auch den noch plastischen Schaumstoff um ein anderes Material, z. B. einen Draht, in entsprechender Weise spritzen kann. Zweckmäßig geschieht dies mittels einer Spritzmaschine, wie sie beispielsweise zum Umspritzen von Drähten und Kabeln mit thermoplastischen Isolierstoffen gebräuchlich ist. Das Umspritzen des Materials, z. B. eines Drahts, mit dem noch plastischen Schaumstoff geschieht wie bei dem Verfahren des Patents in einem Druckraum. It has now been found that when performing the method of named patent also the still plastic foam with a different material, z. B. can inject a wire in a corresponding manner. This is done appropriately by means of an injection molding machine, such as that used, for example, for the injection molding of wires and cables with thermoplastic insulating materials is common. The overmolding of the material, e.g. B. a wire with which still plastic foam happens as in the patent process in a pressure room.

In ihm muß das umspritzte Material so lange verweilen, bis die Erstarrung oder elastische Verfestigung des aufgeschäumten plastischen Stoffes eingetreten ist.The overmolded material must linger in it until it solidifies or elastic solidification of the foamed plastic material occurred is.

Das so mit einer Schicht eines elastischen festen Schaumstoffes umkleidete Material, z. B. Draht, kann noch, wie im Hauptpatent beschrieben, mit einer Schicht von Gummi, Kautschuk, plastischen Kunststoffen u. dgl. umspritzt werden. The so encased with a layer of elastic solid foam Material, e.g. B. Wire, can, as described in the main patent, with a layer rubber, caoutchouc, plastic plastics and the like.
