Description

Verfahren zur Herstellung von Dichtungsmitteln in Strang- oder Bandform Bei der vorliegenden Erfindung handelt es sich tun Dichtungsmittel in Strang- oder Bandform, die dazu bestimmt sind, die Verbindung zwischen verschiedenen festen oder beweglichen Elementen irgendeiner tnechanisehen Einrichtung abzudichten. Derartige Dichtungsorgane werden beispielsweise zwischen die aneinandergeschlossenen Teilstücke einer Gas- oder Flüssigkeitsleitung eingelegt oder zwischen einen Kolben und den Zylinder, in welchem sich der Kolben bewegt.Process for the production of sealants in strand or tape form The present invention is strand or sealant Band shape, which are intended to be the connection between different fixed or to seal movable elements of any mechanical device. Such Sealing organs are, for example, between the mutually connected sections inserted into a gas or liquid line or between a piston and the Cylinder in which the piston moves.

Die Dichtungsmittel, deren Herstellung hier in Frage kommt, sollen wenigstens 50 Asbestfasern in gesponnenem, verdrilltem, verflochtenem oder verwebtem Zustande enthalten.The sealants, the manufacture of which comes into question here, should at least 50 asbestos fibers in spun, twisted, braided or woven States included.

Diese Fäden, Geflechte oder Gewebe werden meistens einer Tränkung und Einbettung unterzogen. Man tränkt sie beispielsweise sehr oft mit Pasten oder Lösungen von Kautschuk und organischen Lösungsmitteln oder mit organischen Lösungen von Kunstharzen.These threads, braids or fabrics are mostly used for an impregnation and embedding. For example, they are very often soaked with pastes or Solutions of rubber and organic solvents or with organic solutions of synthetic resins.

Bei der Verwendung von organischen Lösungsmitteln ergibt sich immer ein erheblicher Verlust an Lösungsmitteln, auch wenn man eines der bekannten Verfahren zur Wiedergewinnung der Lösungsmittel benutzt.When using organic solvents this always results a significant loss of solvents, even when using one of the known processes used to recover the solvents.

Außerdem bildet die Anwendung dieser Lösungsmittel eine dauernde Feuersgefahr und eine Belästigung für die Arbeiter. Da man zu stark verdünnte Lösungen nicht anwenden kann wegen des Bedenkens, daß sich eine ungenügende Menge aufgelösten Stoffes festsetzen würde, so bleibt die Imprägnierung und Einbettung der Fasern oft mangelhaft.In addition, the use of these solvents creates a permanent fire hazard and a nuisance to workers. Because you don't have too much diluted solutions can use because of the concern that there is an insufficient amount of dissolved substance would set, the impregnation and embedding of the fibers often remains inadequate.

Gemäß der Erfindung erfolgt die Tränkung und Einbettung des gesponnenen, geflochtenen oder gewebten Asbests, der zur Herstellung der Dichtungsmittel dient, vermittels wäßriger Dispersionen der in den Asbest einzuführenden Harze oder Gummis.According to the invention, the impregnation and embedding of the spun, braided or woven asbestos used in the manufacture of sealants, by means of aqueous dispersions of the resins or rubbers to be introduced into the asbestos.

Die wäßrigen Dispersionen haben den Vorteil, daß sie weniger viskos sind als die organischen Lösungen der gleichen Stoffe bei gleicher Konzentration. Da das Wasser außerdem ein Dispersionsmittel ist, das nichts kostet, so kann man sich erlauben, sehr verdünnte und dementsprechend breitflüssige Dispersionen zu verwenden, was einen günstigen Einfluß auf die Imprägnierung und Einbettung hat, um so mehr, als Wasser -besonders Wasser, dem Stoffe beigemischt sind, welche die Oberflächenspannung vermindern - den Asbest viel besser feuchtet als organische Lösungsmittel.The aqueous dispersions have the advantage that they are less viscous are than the organic solutions of the same substances at the same concentration. Since water is also a dispersant that costs nothing, you can allow themselves to be very dilute and accordingly wide-bodied dispersions use, which has a favorable influence on the impregnation and embedding, the more so as water, especially water, is mixed with substances that cause the Reduce surface tension - asbestos moistens much better than organic ones Solvent.

Zur Ausführung der Tränkung und Einbettung bedient man sich der Maschinen, welche bisher zur Tränkung und Einbettung mittels Pasten oder organischer Lösungen dienen; beispielsweise bedient man sich für die Asbestgewebe der Streichmaschinen und für die Schnüre der Flechtmaschinen, welche dort, wo sich die Fäden miteinander verbinden, mit einem geeigneten Behälter versehen werden.The machines are used to carry out the impregnation and embedding which were previously used for impregnation and embedding using pastes or organic solutions to serve; For example, coating machines are used for asbestos fabrics and for the cords of the braiding machines, which where the Connect the threads together, put them in a suitable container.

Als Beispiele für wäßrige Dispersionen, die angewendet werden können, seien folgende angegeben: Kautschuk-Latex.As examples of aqueous dispersions that can be used, the following are given: rubber latex.

Eine künstliche Dispersion von regeneriertem Kautschuk in Wasser, in bekannter Weise hergestellt.An artificial dispersion of regenerated rubber in water, produced in a known manner.

Eine künstliche Dispersion von Formaldehyde-Phenol-Kondensationsprodukten in Wasser, in bekannter Weise hergestellt.An artificial dispersion of formaldehyde-phenol condensation products in water, prepared in a known manner.
