Description
Verfahren zur Herstellung von gegen Wärme und chemische Einflüsse widerstandsfähigen isolierenden massen zum Vergießen von Elementen Die Erfindung betrifft ein Verfahren zur Herstellung von isolierenden Massen für den Verguß von Elementen, Batterien, Kabelmuffen u. dgl.Process for the production of against heat and chemical influences Resistant insulating compounds for potting elements The invention relates to a method for the production of insulating masses for the casting of Elements, batteries, cable sleeves and the like.
Man hat bereits vorgeschlagen, leicht schmelzbare und in der Wärme plastische Massen aus Harzen und Montanwachs herzustellen. Auch hat man vorgeschlagen, an Stelle der Harze harzsaure Salze zu ver-,venden und das Montanwachs mit Halogenen oder oxydierenden Mitteln zu behandeln. Aus derartigen Verfahren ergeben sich aber keine so zähen und gegen erhöhte Temperaturen widerstandsfähigen Massen, daß sie für den hier in Betracht kommenden Zweck, einen wärme- .oder tropenfesten Verschauß für Batterien, Kabelmuffen o. dgl. zu bilden, in Betracht kommen. Vielmehr sind die nach den bekannten Verfahren gewonnenen Produkte leicht schmelzbar und in der Wärme plastisch.It has already been proposed to be easily meltable and in the heat to produce plastic masses from resins and montan wax. It has also been suggested to use resin-acid salts instead of the resins and the montan wax with halogens or oxidizing agents. However, such procedures result no masses so tough and resistant to elevated temperatures that they for the purpose under consideration here, a heat- or tropical-proof seal for batteries, cable sleeves o. The like. To be considered. Rather are the products obtained by the known methods are easily meltable and in the Warmth plastic.
Alle nach dem bekannten Verfahren hergestellten Massen weisen den Nachteil auf, daß sie häufig nicht tropenfest sind, d. h. daß sie bei den Temperaturen, die in den Tropen herrschen, weich werden und auseinanderfließen.All compositions produced by the known process have the The disadvantage that they are often not tropicalized, d. H. that at the temperatures that rule in the tropics, soften and flow apart.
Auch schon in nichttropischen Ländern weisen die bisher bekannten Massen häufig den Nachteil auf, daß sie, insbesondere bei Trockenbatterien, den dort auftretenden gesteigerten Temperaturen nicht genügend Widerstand entgegensetzen, so daß die sich entwickelnden Gase die Masse angreifen,-wodurch Blasenbildungen in ihr und andere 'Nachteile entstehen.Even in non-tropical countries, the previously known Masses often have the disadvantage that they, especially in dry batteries, the do not provide sufficient resistance to the increased temperatures occurring there, so that the developing gases attack the mass, -by forming bubbles in her and others' disadvantages arise.
Die vorliegende Erfindung beruht darauf, daß man geeignete Ausgangsstoffe, wie Montanwachse, Erdwachse, Ozokerit, in Verbindung mit Harzen mit Alkalien verseift. Erfindungsgemäß wird diese Verseifung entweder vollkommen oder auch nur unvollkomtnen durchgeführt, was von der Säurezahl der Wachse oder Harze abhängt. Es handelt sich darum, eine Verbindung zu erzielen, die unter Beifügung geeigneter Härtemittel im richtigen Mengenverhältnis eine absolut tropenfeste Vergußmasse ergibt.The present invention is based on the fact that one suitable starting materials, such as montan waxes, earth waxes, ozokerite, saponified with alkalis in connection with resins. According to the invention, this saponification is either complete or only incomplete carried out, which depends on the acid number of the waxes or resins. It is about to achieve a connection which, with the addition of suitable hardening agents, in the correct proportions results in an absolutely tropicalized casting compound.
Beispiel Montanwachs und Harz werden unter Beifügung von Streckmitteln, wie Bitumen und Braunkohlenpeche usw., verschmolzen und auf etwa 8o bis 9o° erhitzt. Unter allmählicher Steigerung der Temperatur entsprechend der zunehmenden Erhöhung des Tropfpunktes wird dieVerseifung langsam vorgenommen, welche je nach der Beschaffenheit des Gemisches entweder vollständig oder nur zu einem Teil erfolgt. Nachdem der Verseifungsprozeß, welcher etwa, q. Stunden in Anspru@cli nimmt, beendet ist, läßt man die Masse etwas erkalten, um dann noch mineralische Beschwerungs- und Farbsubstanzen unterzurühren.Example montan wax and resin are added with the addition of extenders, such as bitumen and lignite pitch etc., fused and heated to about 80 to 90 degrees. Gradually increasing the temperature in accordance with the increasing increase the dropping point, the saponification is carried out slowly, which depends on the nature of the mixture takes place either completely or only in part. After the saponification process, which about, q. Hours in Anspru @ cli takes, is finished, you leave the mass a little cool to then stir in mineral weight and color substances.
