To produce a laminated woven fabric such as can be used for the manufacture of a sole of an overshoe for reactor operation, the fabric is impregnated or pasted with a rubber solution; this pretreated fabric is covered by a thin rubber panel, after which rubber solution and rubber panel are fully cured at the same time and together, for example on the rotation curing machine known as "AUMA". Rubber solution and rubber panel are expediently based on the same natural rubber basic mixture.

Description

Verfahren zur Herstellung eines kaschierten GewebesProcess for the production of a laminated fabric

sowie aus einem solchen kaschierten Gewebe hergestellte Sohle eines Uberschuhs für den Reaktorbetrieb Die Erfindung betrifft ein Verfahren zur Herstellung eines kaschierten Gewebes, insbesondere für die Sohle eines Überschuhs für den Reaktorbetrieb, sowie eine aus einem solchen kaschierten Gewebe hergestellte Sohle eines Überschuhs für den Reaktorbetrieb.and a sole made from such a laminated fabric Overshoe for reactor operation The invention relates to a method for production a laminated fabric, especially for the sole of an overshoe for reactor operation, and a sole of an overshoe made from such a laminated fabric for reactor operation.

Für den Reaktorbetrieb werden einfache, leicht anzuziehende Uberschuhe in großer Stückzahl benötigt. Solche Überschuhe bestehen im allgemeinen aus einer verschleiß- und rutschfesten Sohle, auf deren Rand ein oben offener Stoffbeutel aufgenäht ist. Die Öffnung dieses Stoffbeutels wird durch ein Gummiband zusammengezogen.Simple, easy-to-wear overshoes are required for reactor operation needed in large numbers. Such overshoes generally consist of one Wear-resistant and non-slip sole, on the edge of which is an open-top cloth bag is sewn on. The opening of this fabric bag is pulled together by a rubber band.

Die wesentlichen Gebrauchseigenschaften eines solchen Uberschuhs werden durch die Eigenschaften der Sohle bestimmt, die, wie erwähnt, verschleiß- und rutschfest sein muß; außerdem muß der gesamte Überschuh einschließlich der Sohle waschbar sein, damit an dem überschub und insbesondere der Sohle haftende, radiaktive Partikel abgespült werden können. Diese Eigenschaften werden durch die bisher üblichen Sohlen solcher Überschuhe nicht erreicht.The essential properties of use of such an overshoe are determined by the properties of the sole, which, as mentioned, is wear and slip resistant have to be; In addition, the entire overshoe including the sole must be washable, radioactive particles adhering to the slip and in particular to the sole can be rinsed off. These properties are due to the previously common soles such overshoes not achieved.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren zur Herstellung eines kaschierten Gewebes zu schaffen, das die erwähnten, für die Verwendung als Sohle von Überschuhen wesentlichen Eigenschaften hat.The invention is therefore based on the object of providing a method for Manufacture of a laminated fabric to create the ones mentioned for use has essential properties as the sole of overshoes.

Insbesondere soll ein kaschiertes Gewebe für die Sohle eines Überschuhs im Reaktorbetrieb vorgeschlagen werden, das ohne Probleme gewaschen werden kann.In particular, a laminated fabric is intended for the sole of an overshoe be proposed in the reactor operation, which can be washed without problems.

Dies wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale erreicht.This is according to the invention by the characterizing part of the claim 1 achieved characteristics.

Zweckmäßige Ausführungsformen sind in den Unteransprüchen zusammengestellt.Appropriate embodiments are compiled in the subclaims.

Die mit der Erfindung erzielten Vorteile beruhen insbesondere darauf, daß sich durch die beanspruchten Maßnahmen eine sehr gute Haftung zwischen der Gummischicht und dem Gewebe ergibt,da ja die Kautschuk-Lösung und die Kautschukplatte gleichzeitig, beispielsweise auf der AUMA, vulkanisiert werden und dadurch eine sehr enge Bindung eingehen. Hierbei ist auch wesentlich, daß die Kautschuk-Lösung und die Kautschuk-Masse auf der gleichen Kautschuk-Grundmischung, im allgemeinen einer Natürkautschuk-Mischung, beruhen, also von Hause aus eine chemische Affinität gegeben ist.The advantages achieved with the invention are based in particular on that the claimed measures result in very good adhesion between the rubber layer and the fabric, since the rubber solution and the rubber sheet at the same time, for example at the AUMA, and thus a very close bond enter. It is also essential that the rubber solution and the rubber mass on the same basic rubber mixture, generally a natural rubber mixture, are based, i.e. there is a natural chemical affinity.

Dieses kaschierte Gewebe läßt sich auch beliebig waschen, ohne daß es am Rand der Sohle zu Ausfransungen kommt oder sich die Gummischicht von dem Gewebe löst.This laminated fabric can also be washed as desired without there is fraying at the edge of the sole or the rubber layer from the fabric solves.

Gute Ergebnisse wurden mit einer 10 bis 20 %-igen Kautschuklösung auf der Basis von Tuluol erhalten.Good results have been achieved with a 10 to 20% rubber solution obtained on the basis of tuluol.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert.The invention is illustrated below using an exemplary embodiment explained in more detail.

Zunächst wurde eine Kautschuk-Mischung auf der Basis der folgenden Rezeptur hergestellt: 100 Teile Naturkautschuk 2,08 Teile Stearinsäure 2,83 Teile Zinkoxid 2,08 Teile Dispergator 0,76 Teile Alterungsschutzmittel 10,01 Teile Faktis 41,700 Teile Kieselsäure aktiv 18,50 Teile Titandioxid 18,90 Teile Weichmacher 3,02 Teile Thiuram-Beschleuniger, insbesondere TMDT 0,57 Teile 2-Merkapto-dimidazolin-BeschleuniKger Aus dieser Naturkautschuk-Grundmischung wurde mit Toluol eine 15%-ige Lösung hergestellt.First, a rubber mixture was prepared based on the following Recipe made: 100 parts of natural rubber 2.08 parts of stearic acid 2.83 parts of zinc oxide 2.08 parts of dispersant 0.76 parts of anti-aging agent 10.01 Parts of factice 41.700 parts of silica active 18.50 parts of titanium dioxide 18.90 parts Plasticizer 3.02 parts thiuram accelerator, in particular TMDT 0.57 part 2-mercapto-dimidazoline accelerator A 15% solution was made from this natural rubber base mixture with toluene.

Parallel hierzu wurde diese Naturkautschuk-Grundmischung auf dem Kalander in der üblichen Weise zu einer dünnen Platte gezogen.At the same time, this natural rubber base mixture was applied to the calender drawn into a thin plate in the usual way.

Wesentlich ist hierbei, daß in den beiden ersten, parallelen Verarbeitungsschritten der Naturkautschuk-Grundmischung noch keine Vulkanisation einsetzt.It is essential here that in the first two, parallel processing steps the natural rubber base mixture does not yet vulcanize.

Dann wurde ein handelsübliches Gewebe, insbesondere ein Gewebe auf der Basis von Polyester, Polyamid, Baumwolle oder Zellwolle mit dieser Kautschuk-Lösung getränkt oder geteigt, wobei das für die Aufbringung der Kautschuklösung angewandte Verfahren von ihrer Viskosität abhängt.A commercially available fabric, in particular a fabric, was then applied the basis of polyester, polyamide, cotton or rayon with this rubber solution soaked or dough, which is used for the application of the rubber solution Method depends on their viscosity.

Besonders gute Ergebnisse wurden mit einem Baumwollgewebe erhalten.Particularly good results have been obtained with a cotton fabric.

Das getränkte oder geteigte Gewebe wurde dann auf der auch unter der Bezeichnung "AUMA" bekAnnten Rotationsvulkanisiermaschine mit der Kautschuk-Platte belegt und unter gleichzeitiger Vernetzung des Naturkautschuks der Lösung und der Platte ausvulkanisiert.The soaked or pasted tissue was then placed on the underneath Designation "AUMA" known rotation vulcanizing machine with the Rubber sheet covered and with simultaneous crosslinking of the natural rubber the solution and the plate vulcanized.

Das auf diese Weise mit einer aufkaschierten Gummischicht versehene Gewebe wurde dann auf die für die Herstellung der Sohlen für den Über schuh erforderliche Größe geschnitten, wonach dann in der üblichen Weise das Material des Überschuhs aufgenäht wurde.The one provided in this way with a laminated rubber layer Tissue was then made onto the ones required for the manufacture of the soles for the overshoe Cut to size, after which the material of the overshoe is then used in the usual way was sewn on.

Ein solcher überschub konnte häufig gewaschen werden, wie es für das Abspülen von anhaftenden radioaktiven Partikeln erforderlch ist, ohne daß es im Randbereich der Sohle zu Ausfransungen oder zu einer Ablösung der Gummischicht von dem Gewebe kam.Such an overflow could be washed frequently as it is for that Rinsing of adhering radioactive particles is necessary without it being in the Edge area of the sole to fraying or to a detachment of the rubber layer from came to the tissue.
