Description
Verfahren zur Verbesserung der Eigenschaften von Guttapercha, Balata u. dgl. und deren Mischungen. Es ist bekannt, daß man Harze durch Behandeln mit Kalk oder anderen Metalloxyden oder -hydroxyden härten kann.Process for improving the properties of gutta-percha, balata and the like and their mixtures. It is known that resins can be treated with Lime or other metal oxides or hydroxides can harden.
Versuche haben ergeben, daß die elektrischen und mechanischen Eigenschaften von Guttapercha, Murac und Balata oder ähnlichen, aus ;Milchsäften gewonnenen Erzeughissen, die nicht vulkanisiert werden, bedeutend verbessert werden, wenn man die in ihnen enthaltenen natürlichen Harze härtet. Das Verfahren beschränkt sich jedoch nicht auf die Härtung der in den angeführten Milchsafterzeugnissen enthaltenenHarze, sondern kann auch derart ausgeführt werden, daß den entharzten Naturerzeugnissen andere Qehärtete Harze zugesetzt werden.Tests have shown that the electrical and mechanical properties of gutta-percha, murac and balata or similar products made from milk juices, that are not vulcanized can be greatly improved if you have the ones in them contained natural resins hardens. However, the procedure is not limited on the hardening of the resins contained in the milk juice products listed, but can also be carried out in such a way that the resin-removed natural products are different Cured resins can be added.
Das Verfahren der Erfindung kann in verschiedener Weise ausgeführt werden. Zunächst ist es möglich, die in den Naturerzeugnissen enthaltenen Harze in der Masse durch Anwendung von Wärme und Zugabe der entsprechenden Metalloxyde oder -hydroxyde in trockner oder nasser Form unmittelbar in Hartharze zu verwandeln.The method of the invention can be carried out in various ways will. First of all, it is possible to use the resins contained in natural products in the mass by applying heat and adding the appropriate metal oxides or hydroxides in dry or wet form directly into hard resins.
Ein weiterer Weg ist, die angeführten Naturerzeugnisse teilweise oder ganz zu entharzen und den so behandelten Milchsafterzeugnissen die in einem Sonderverfahren gehärteten Harze wieder beizumischen. Dieses Verfahren kann auch dahin abgeändert werden, daß man statt der ausgezogenen Harze gehärtete Harze anderen Ursprungs beimischt. Man hat es nach diesem Verfahren in der Hand. -den Härtharzgehalt des Erzeug-. nisses dem Verwendungszwecke anzupassen. Dieses Verfahren hat den Vorteil, daß die Guttapercha bzw. Balata der Wärmebehandlung nicht mit unterworfen werden und daher unter dem Härteverfahren nicht leiden. Es findet dann auch keine Depolymerisation statt. Die Harze können restlos in Hartharze übergeführt werden. Die Behandlung der Masse ist schonender, und man erhält ein besseres Enderzeugnis.Another way is to use the listed natural products partially or to completely de-resinate and the milk juice products treated in this way in a special process to mix in hardened resins again. This procedure can also be changed in this way that hardened resins of other origin are admixed instead of the drawn out resins. After this procedure you have it in your hand. -the hardening resin content of the product-. nisses to adapt to the intended use. This procedure has the advantage that the gutta-percha or balata are not subjected to the heat treatment and therefore under the Hardship procedures do not suffer. There is then also no depolymerization. the Resins can be completely converted into hard resins. Treating the crowd is gentler, and you get a better end product.
Beispiele. r. Harzreiche Guttapercha, Murac -oder Balata, deren Harzgehalt vorher genau ermittelt ist, wird auf etwa r8o° erhitzt und die für den ermittelten Harzgehalt zur Bildung von Hartharz notwendige Menge Kalkmilch von etwa zo°Be unter ständigem Durchmischen zugesetzt. Die Erhitzung wird so lange fortgesetzt, bis das gesamte Wasser verdampft ist, worauf die Weiterverarbeitung nach den üblichen Verfahren erfolgt.Examples. r. Resin-rich gutta-percha, murac or balata, their resin content is precisely determined beforehand, it is heated to around r8o ° and the determined for the Resin content for the formation of hard resin required amount of milk of lime of about zo ° Be below Added to constant mixing. The heating continues until the all the water has evaporated, whereupon further processing according to the usual procedures he follows.
z. Harze aus 1,l:ilchsafterzeugnissen oder andere Harze, wie Kolophonium, Akaroidharze usw., werden nach den üblichen Verfahren durch Überführen in Metallsalze gehärtet. Diese gehärteten Harze werden in je nach dem Verwendungszwecke verschiedenen Mengen ganz oder teilweise entharzten Milchsafterzeugnissen zugesetzt.z. Resins made from 1, l: milk juice products or other resins, such as rosin, Acaroid resins, etc., are made into metal salts by the usual methods hardened. These hardened resins are used in various different ways Amounts of wholly or partially resinified milk juice products added.
Es ist bekannt,. Mischungen von Kautschuk, der lediglich in vulkanisiertem Zustande verwendet wird, Bleiglätte, Magnesia oder Kalk zuzusetzen, um bei der Vulkanisation verschiedene Härten der vulkanisierten Masse zu erzielen. Das vorliegende Verfahren bezweckt demgegenüber die Verbesserung der elektrischen und mechanischen Eigenschaften von Guttapercha oder ähnlichen Milchsafterzeugnissen, die nicht vulkanisiert . «=erden.It is known,. Mixtures of rubber that is only vulcanized in Condition is used to add black lead, magnesia or lime to help with vulcanization different To achieve hardening of the vulcanized mass. The purpose of the present proceedings is in contrast, the improvement in the electrical and mechanical properties of Gutta-percha or similar milk juice products that do not vulcanize. «= Earth.
