Klebstoff für elektrolytisehe Bauelemente, wie Aluminium-ElektrolytkondensatorenAdhesive for electrolytic components, such as Aluminum electrolytic capacitors
Die vorliegende Erfindung betrifft Mischungen mit einstellbaren Viskositäten, die als Klebstoff oder Vergußmasse zum Kleben, Fixieren bzw. Vergießen von elektrolytischen Bauelementen, insbesondere von Nass-Aluminium-Elektrolytkondensatorenwickeln, dienen.The present invention relates to mixtures with adjustable viscosities that are used as adhesives or potting compounds Gluing, fixing or potting of electrolytic components, in particular of wet aluminum electrolytic capacitor windings, to serve.
Die Klebstoffe bestehen meistens aus natürlichen Stoffen, wie Stärke, Bitumen, Harae etc., oder aus synthetischen Stoffen, wie Elastomere, Phenolharze, Silikate oder Cyanat."The adhesives mostly consist of natural materials such as starch, bitumen, harae, etc., or synthetic materials Substances such as elastomers, phenolic resins, silicates or cyanate. "
Die Klebstoffe zeigen je nach Verwendungszweck und Beschaffenheit der zu klebenden Materialien mehr oder weniger befriedigende Resultate. Die meisten herkömmlichen Klebstoffe und Vergußmassen eignen sich nur schlecht als Haftmittel in Aluminium-Elektrolytkondensatoren oder erwiesen sich sogar als schädlich in bezug auf Lebensdauer und die elektrischen Eigenschaften der fertigen Kondensatoren. Die Gründe dafür sind zahlreich und verzweigt; die wichtigsten sind:The adhesives show up depending on the intended use and nature the materials to be bonded more or less satisfactory results. Most conventional adhesives and potting compounds are poorly suited, or even proven, as adhesives in aluminum electrolytic capacitors as detrimental to the life and electrical properties of the finished capacitors. The reasons for it are numerous and branched; the most important are:
1.) Die Anodenoxidsperrschicht der Aluminium-Elektrolytkondensatoren wird bei einer Halogenkonzentration von ^ 5ppm1.) The anode oxide barrier layer of the aluminum electrolytic capacitors becomes at a halogen concentration of ^ 5ppm

zerstört, was zur Zerstörung der Kondensatoren führen kann. Die meisten Klebstoffe, enthalten als Bestandteil Halogenverbindungen, z.B. chlorierte Kautschuke, oder sie benötigen Halogenverbindungen in Form von Katalysatoren für ihre Polymerisation, z.B. Ziegler-Natta-Katalysatoren. Außerdem lassen sich die Katalysatorenreste nur sehr schwer ohne wesentliche Steigerung der Klebstoffkosten entfernen. Aus diesen Gründen können sie nicht verwendet werden.destroyed, which can lead to the destruction of the capacitors. Most adhesives contain that as an ingredient Halogen compounds, e.g. chlorinated rubbers, or they require halogen compounds in the form of catalysts for their polymerization, e.g. Ziegler-Natta catalysts. In addition, the catalyst residues very difficult to remove without a substantial increase in adhesive costs. For these reasons, you can they are not used.
2.) Klebstoffe, die edlere Metalle als Aluminium enthalten, d.h. Metalle mit Normalpotential 'P' -1,67 V (mit wenigen Ausnahmen) können nicht verwendet werden. Bei Verwendung solcher Klebstoffe entsteht je nach dem „ des Elektrolyten die sogenannte Lokalelementkorrosion.2.) Adhesives that contain more noble metals than aluminum, ie metals with normal potential 'P' -1.67 V (with a few exceptions) cannot be used. When such adhesives are used, so-called local element corrosion occurs depending on the “electrolyte”.
3.) Klebstoffe, die Sulphate, Nitrate oder größere Mengen Phosphate oder auch lösliche Carbonsäurereste enthalten, sind nicht geeignet. Die Gegenwart von diesen Stoffen kann sowohl Beschädigungen der Anodenoxidsperrschicht als auch Änderungen der Leitfähigkeit des Elektrolyten hervorrufen.3.) Adhesives that contain sulphates, nitrates or larger amounts of phosphates or soluble carboxylic acid residues, are not suitable. The presence of these materials can both damage the anode oxide barrier as well as causing changes in the conductivity of the electrolyte.
4.) Die Elektrolyte der Elektrolytkondensatoren enthalten hochpolare Lösungsmittel, z.B. Glykole, Alkohole, Säureamide, Ester, Äther, etc.. Die meisten bekannten Klebstoffe werden in diesen polaren Lösungsmitteln aufgelöst oder verlieren ihre Klebfähigkeit. Der Auslösungsprozess wird durch die Wärmebehandlung der Kondensatoren und dem Betrieb bei Temperaturen von +700C bis +12 50C beschleunigt.4.) The electrolytes of the electrolytic capacitors contain highly polar solvents, eg glycols, alcohols, acid amides, esters, ethers, etc .. Most known adhesives are dissolved in these polar solvents or lose their adhesiveness. The initiation process is accelerated by the heat treatment of the capacitors and operating at temperatures ranging from +70 C to +12 0 5 0 C.

Die Stoffe oder Verbindungen, die unter 1, 2 und 3 erwähnt sind, werden im folgenden kurz schädliche Verbindungen (SV) genannt.The substances or compounds mentioned under 1, 2 and 3 are, in the following, harmful compounds (SV) are briefly mentioned.
Im Sinne der Erfindung kommen SV-freie peroxid-vulkanisierbare Elastomere vom Typ Äthylen-Propylen oder Äthylen-Propylen-Dien als Hauptbestandteil in Frage. Diese Elastomere sind unlöslich in den Elektrolyten der Aluminium-Elektrolytkondensatoren. Sie werden in einem geeigneten SV-freien, flüchtigen Lösungsmittel, das das Vernetzungsmittel enthält, gelöst. Es sind keine Füllstoffe notwendig. Je nach der Verarbeitungsmethode und Bedingung, s.b! maschinelle oder Hand-Verarbeitung, Dicke des Anodenabstandhalters oder. Klebebandes., kann der Klebrigkeitswert durch Zugabe von nicht mehr als 30 % anderer Klebstoffe erhöht werden. Es ist selbstverständlich5 daß diese zur Klebrigkeitserhöhung dienenden Klebstoffe frei von SV sein müssen. Diese Klebstoffzusätze können Butylkautschuk, Styrol-Butadienkautschuk, Polybutadien9Phenolharz oder Isopren-Kautschuk sein.For the purposes of the invention, SV-free peroxide-vulcanizable elastomers of the ethylene-propylene or ethylene-propylene-diene type come into consideration as the main component. These elastomers are insoluble in the electrolytes of the aluminum electrolytic capacitors. They are dissolved in a suitable SV-free, volatile solvent which contains the crosslinking agent. No fillers are necessary. Depending on the processing method and condition, sb! machine or hand processing, thickness of the anode spacer or. Adhesive tape., The tack value can be increased by adding no more than 30% other adhesives. It goes without saying that these 5 serving for Klebrigkeitserhöhung adhesives must be free of SV. These adhesive additives can be butyl rubber, styrene-butadiene rubber, polybutadiene 9, phenolic resin or isoprene rubber.
Beispiel 1: ■Example 1: ■
Es werden 15 bis 20 Teile SV-freie Äthylen-Propylen-Dien-Elastomere in 80 bis 85 Teilen eines S¥-freien Lösungsmittels, vorzugsweise reines Benzin Sp0GeW. 0s7, gelöst» Als Vernetzer werden 1,5 bis 2 Teile eines Peroxid, vorzugsweise Cummilperoxid, zugegeben. Die Viskosität des Klebelackes kann durch Verdunsten oder Zugabe von Lösungsmitteln variiert werden.There are 15 to 20 parts of SV-free ethylene-propylene-diene elastomers in 80 to 85 parts of an S ¥ -free solvent, preferably pure gasoline Sp 0 GeW. 0 s 7, dissolved »1.5 to 2 parts of a peroxide, preferably rubber peroxide, are added as crosslinking agent. The viscosity of the adhesive varnish can be varied by evaporating or adding solvents.

genannten Klebstoffgemisches vermischt.70 to 90 parts of the adhesives mentioned in Example 1 are mixed with 30 to 10 parts of one in Examples 2 to 4
named adhesive mixture mixed.
Das Verkleben wird durch Auftragen einer dünnen Schicht des Klebers auf das Ende des Anodenabstandhalters bewerkstelligt,
und zwar so, daß mindestens zwei Umwicklungen des Kondensatorenwickels mit Kleber bedeckt sind. Ähnlich kann der Kleber
auf einem geeigneten Band aufgebracht werden, mit dem
dann der Kondensatorenwickel umwickelt wird. Durch die WärT
mebehandlung der Kondensatoren während der Trockung oder der Nachformierung wird der Kleber vulkanisiert.Gluing is accomplished by applying a thin layer of the adhesive to the end of the anode spacer so that at least two turns of the capacitor coil are covered with adhesive. Similarly, the adhesive can be applied to a suitable tape with the
then the capacitor winding is wrapped. The adhesive is vulcanized by the heat treatment of the capacitors during drying or reforming.
