Description

Verfahren zum Imprägnieren von Faserstoffen und Geweben mit wäßrigen Kautschukdispersionen unter Verwendung von Netzmitteln Bei der Herstellung solcher Gebrauchsgegenstände, bei denen die wertvollen Eigenschaften des Kautschuks zur Auswirkung kommen sollen, wie z. B. Kautschukschläuchen, Auto- und Fahrradreifen, wasserdichten Stoffen, Isoliermassen u. a., ist es oft erforderlich, um eine genügende mechanische Festigkeit zu :erzielen, den Kautschuk in Gemeinschaft mit Faserstoffen, wie z. B. Baumwoll-, Leinen-, Jute- oder Asbestgespinsten bzw. -geweb.en, zu verarbeiten. Dies kann so ausgeführt werden, daß die Faserstoffe mit einer wäßrigen Kautschukdispersion behandelt und anschließend ,getrocknet werden. Auf die kautschukierten Flächen wird nötigenfalls weiteres Kautschukmaterial aufgebracht, und das Ganze wird schließlich gegebenenfalls vulkanisiert. Bei der Verwendung einer solchen Kautschukdispersion zeigt sich aber der Übelstand, daß diese an der Oberfläche des Faserstoffes koaguliert und nicht oder nur sehr schwer in das Innere der Faser eindringt. Infolgedessen haftet der nach dem Ei;ntrocknen der Dispersion entstehende Kautschuküberzug nur schlecht auf der Faser und läßt sich durch mechanische Behandlung leicht wieder von ihr :entfernen.Process for impregnating fibrous materials and fabrics with aqueous Rubber dispersions using wetting agents in the preparation of such Articles of daily use in which the valuable properties of rubber are used Impact should come, such. B. rubber tubes, car and bicycle tires, Waterproof materials, insulating compounds and others, it is often necessary to have a sufficient mechanical strength to: achieve the rubber in association with fibers, such as B. cotton, linen, jute or asbestos spun or fabric. This can be done so that the fiber materials with an aqueous rubber dispersion treated and then dried. On the rubberized surfaces if necessary additional rubber material is applied, and the whole thing is finally if necessary vulcanized. When using such a rubber dispersion but shows the disadvantage that this coagulates on the surface of the fiber and does not penetrate into the interior of the fiber or only with great difficulty. Consequently the rubber coating that forms after the dispersion has dried only adheres bad on the fiber and can be easily restored by mechanical treatment from her: remove.

Es ist deshalb schon vorgeschlagen worden, zu der Kautschukdispersion Netzmittel hinzuzufügen: Die bekannten, zu diesem Zweck verwendeten Netzmittel von der Gruppe der alkylaryls.ul;fonsauren Salze haben, obgleich deren Kalk- oder Magnesiumsalze in Wasser leicht löslich sind, nicht die Eigenschaift. bei Verwendung von hartem Wasser die vorzeitige Ausflockung .der Kautschukdispersionen zu verhindern. nie ebenfalls zu diesem Zweck schon vorgeschlagenen gallensauren Salze sind unbeständig gegen die Härtebildner des Wassers und daher ebenfalls nur bei Anwendung von destilliertem oder weichem Wasser anwendbar.It has therefore already been proposed for the rubber dispersion Add wetting agents: The well-known wetting agents used for this purpose by of the group of the alkylarylsulphonic acid salts, although their lime or magnesium salts are easily soluble in water, not the property. when using hard Water to prevent premature flocculation of the rubber dispersions. never Bile salts which have already been proposed for this purpose are unstable against the hardness components of water and therefore only when using distilled water or soft water.

Erfindungsgemäß werden den zur Behandlung der Faserstoffe verwendeten Kautschukdispersionen die Kondensationsprodukte von höheren Fettsäuren und hochmolekularen Eiweißspaltprodukten als Netzmittel zugesetzt, wie sie nach dem Verfahren der französischen Patentschrift 749 228 erhältlich sind. Diese Netzmittel haben den Vorteil, bei ihrer Verwendung in hartem Wasser, in dem sie beständig sind, die vorzeitige Koagulation der Kautschukdispersionen zu verhindern, so daß-ihre Anwendung auch bei hartem Wasser möglich ist.According to the invention are used for treating the fibrous materials Rubber dispersions are the condensation products of higher fatty acids and high molecular weight Protein breakdown products are added as a wetting agent, as used by the French 749 228 are available. These wetting agents have the advantage in their Use in hard water where they are resistant to premature coagulation to prevent the rubber dispersions, so that-their use even in hard water is possible.

Man kann auch so vorgehen, daß man die Faserstoffe mit den Lösungen von Kondensationsprodukten höherer Fettsäuren und hochmolekularer Eiweißspaltprodukte imprägniert und dann diese vorbearbeiteten Fasern mit der Kautschukdispersion behandelt.One can also proceed in such a way that the fibrous materials are mixed with the solutions of condensation products of higher fatty acids and high molecular weight protein breakdown products impregnated and then treated these preprocessed fibers with the rubber dispersion.
