Description

Isolierkörper auf Epoxydharzbasis mit verbesserten mechanischen Eigenschaften Bisphenolepoxydharze eignen sich bekanntlich wegen ihrer thermischen Beständigkeit und wegen der verhältnismäßig geringen dielektrischen Verluste bei höheren Temperaturen für die Herstellung von Isolierformkörpern für elektrotechnische Zwecke.Insulating body based on epoxy resin with improved mechanical properties Bisphenol epoxy resins are known to be suitable because of their thermal resistance and because of the relatively low dielectric losses at higher temperatures for the production of insulating moldings for electrotechnical purposes.

Da bei der Verarbeitung dieser Gießharze beim Härtungsprozeß Schrumpfspannungen auftreten können, welche sich, j e nach den einzubettenden Elementen, verschieden auswirken, hat man versucht, durch Zusatz von Monoepoxydverbindungen, wie Styroloxyd oder Phenylglycidyläther, den Erweichungsbereich und damit die eingefrorene Spannung derartiger Formkörper herabzusetzen. Durch Herabsetzung des Erweichungsbereiches werden aber die dielektrischen Verluste bei höheren Betriebstemperaturen erhöht, wodurch die Verwendung dieser Formkörper für den genannten Zweck nachteilig beinflußt wird.Because shrinkage stresses during the hardening process during the processing of these casting resins which differ depending on the elements to be embedded have an effect, attempts have been made by adding monoepoxy compounds such as styrene oxide or phenyl glycidyl ether, the softening area and thus the frozen tension reduce such shaped bodies. By reducing the softening range but if the dielectric losses are increased at higher operating temperatures, thereby adversely affecting the use of these molded bodies for the stated purpose will.

Es wurde nun gefunden, daß man zu Isolierformkörpern gelangen kann, welche unter Beibehaltung der guten thermischen und dielektrischen Eigenschaften bei den in Frage kommenden Betriebstemperaturen wesentlich verbesserte mechanische Eigenschaften, insbesondere eine erhöhte Zähigkeit aufweisen.It has now been found that insulating moldings can be obtained which while maintaining the good thermal and dielectric properties significantly improved mechanical at the operating temperatures in question Properties, especially increased toughness.

Gegenstand der Erfindung ist die Verwendung eines mit einem Zusatz von monomerem linearem aliphatischem Diglycidyläther versehenen Bisphenolepoxydharzes zur Herstellung von Isolierformkörpern für elektrotechnische Zwecke.The invention relates to the use of one with an additive bisphenol epoxy resin provided with monomeric linear aliphatic diglycidyl ether for the production of insulating moldings for electrotechnical purposes.

Gemäß einer Ausgestaltung der Erfindung eignen sich als Zusätze besonders Diglycidyläther von 1,4-Butandiol oder von 1,6-Hexandiol.According to one embodiment of the invention, additives are particularly suitable Diglycidyl ether of 1,4-butanediol or of 1,6-hexanediol.

Durch Zusatz der Diglycidyläther zu den Bisphenolepoxydharzen wird die Schlagzähigkeit z. B. um das Doppelte gegenüber den reinen Bisphenolepoxydharzkörpern verbessert, wobei die Formbeständigkeit nach M a r t en s beibehalten wird. So zeigten z. B. Formkörper, welche unter Verwendung von 100 Teilen Bisphenolepoxydharz mit 30 Gewichtsprozent Phthalsäureanhydrid hergestellt wurden - Aushärtung: 15 Stunden bei 120° C -, eine Schlagzähigkeit von 15 cmkg/cm2 und eine Martenszahl von 99° C. Demgegenüber wird unter den gleichen Herstellungsbedingungen bei Zusatz von 5'°/a 1,4-Butandiglycidyläther ebenfalls unter Verwendung von Phthalsäureanhydrid ein Formkörper erhalten, dessen Martenszahl 95° C und dessen Schlagzähigkeit 32 cmkg/cm2 beträgt.By adding the diglycidyl ether to the bisphenol epoxy resins the impact strength z. B. twice as much as the pure bisphenol epoxy resin bodies improved, the dimensional stability according to Marten s is retained. So showed z. B. Moldings, which using 100 parts of bisphenol epoxy resin with 30 percent by weight of phthalic anhydride were produced - curing: 15 hours at 120 ° C -, an impact strength of 15 cmkg / cm2 and a Martens number of 99 ° C. On the other hand, under the same manufacturing conditions with the addition of 5% / a 1,4-butanediglycidyl ether also using phthalic anhydride Shaped body obtained, its Martens number 95 ° C and its impact strength 32 cmkg / cm2 amounts to.

Eine Verbesserung der mechanischen Eigenschaften wird gemäß einer weiteren Ausgestaltung der Erfindung durch Zusatz von Mengen bis zu 25 Gewichtsprozent, bezogen auf die Bisphenolepoxydharzkomponente, erreicht. Für bestimmte Zwecke lassen sich auch höher kondensierte Diglycidyläther als Zusatz zur Herstellung eines Isolierkörpers verwenden.An improvement in the mechanical properties is according to a further embodiment of the invention by adding amounts of up to 25 percent by weight, based on the bisphenol epoxy resin component. Leave for specific purposes Highly condensed diglycidyl ethers can also be used as an additive for the production of an insulating body use.

Die gemäß dem Erfindungsgegenstand verwendeten Stoffe sind an sich bekannt und ihr Herstellungsverfahren nicht Gegenstand der vorliegenden Erfindung.The substances used in accordance with the subject matter of the invention are per se known and their manufacturing process is not the subject of the present invention.
