Description
Verfahren zur Herstellung vernetzter siliciumhaltiger Kunstharze erhöhter thermischer und mechanischer Beständigkeit Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Vernetzungsprodukten von aromatischen Orthokieselsäureestern mit OH-gruppenhaltigen Verbindungen. Solche Umsetzungen sind schon früher vorgeschlagen worden. Es handelte sich beispielsweise darum, ein ölmodifiziertes Alkydharz mit Phenylorthosilikat umzusetzen. Hierbei wird ein je nach Menge des benutzten Orthosilikats ein mehr oder weniger vernetzter Kunststoff gewonnen, der beispielsweise als Isolierstoff für elektrotechnische Zwecke Verwendung finden kann. Bei diesen Verfahren ergeben sich folgende Schwierigkeiten. Sind die Substituenten des Kieselsäureesters klein, so erfolgt die Reaktion weitgehend und sehr rasch, wobei dann aber Stoffe entstehen, die verhältnismäßig spröde sind und bei thermischer Beanspruchung zur Rißbildung neigen. Verwendet man dagegen aromatische Ester mit größeren Substituenten, dann wird zwar die thermische und mechanische Beständigkeit besser, aber zur Umsetzung werden wesentlich höhere Temperaturen bzw. längere Härtungszeiten benötigt. Process for the production of crosslinked silicon-containing synthetic resins increased thermal and mechanical resistance The invention relates to a process for the preparation of crosslinking products of aromatic orthosilicic acid esters with compounds containing OH groups. Such implementations have been suggested earlier been. It was, for example, an oil-modified alkyd resin with Implement phenyl orthosilicate. Here, depending on the amount of orthosilicate used a more or less cross-linked plastic obtained, for example as an insulating material can be used for electrotechnical purposes. Result from these procedures the following difficulties. If the substituents on the silicic acid ester are small, so the reaction takes place largely and very quickly, but then substances are formed, which are relatively brittle and cause cracks to form when exposed to thermal stress tend. If, on the other hand, aromatic esters with larger substituents are used, then the thermal and mechanical resistance is better, but for implementation significantly higher temperatures or longer curing times are required.
Erfindungsgemäß werden diese Mängel vermieden, indem bei dem genannten Verfahren als aromatische Orthokieselsäureester Mischester verwendet werden, insbesondere Stoffe mit mindestens zweierlei verschieden großen aromatischen Resten. So wird z. B. der größere Rest mindestens einen Ring mehr enthalten als der kleinere. Als kleinere Reste kommen beispielsweise Phenyl- oder Kresylreste, als größere Reste Naphthyl-oder Biphenylreste in Betracht. According to the invention, these shortcomings are avoided by using the aforementioned Processes are used as aromatic orthosilicic acid ester mixed esters, in particular Substances with at least two different sized aromatic residues. So will z. B. the larger remainder contain at least one ring more than the smaller one. as smaller radicals come, for example, phenyl or cresyl radicals than larger radicals Naphthyl or biphenyl radicals are suitable.
Durch die Verwendung solcher Mischester lassen sich die Vorteile der nach den obengenannten Reaktionen erzielten Stoffe erzielen, ohne daß die Nachteile in Kauf genommen zu werden brauchen. By using such mixed esters, the advantages achieve the substances obtained by the above reactions without the disadvantages need to be accepted.
Beispiel 440 g Tri-Biphenylmonokresyl-o-silikat werden mit 250 g eines plastifizierten Phenolharzes und 350 g eines fettsäuremodifizierten Alkydharzes gemischt. Diese Mischung wird in 1000 g Xylol gelöst und kann beispielsweise zum Tränken der Wicklungen elektrischer Geräte verwendet werden. Diese Wicklungen werden anschließend 8 Stunden auf eine Temperatur von 140"C erwärmt wobei nach Abdampfen des Lösungsmittels die Durchhärtung durch Vernetzung erfolgt. Example 440 g of tri-biphenyl monocresyl-o-silicate are added with 250 g of a plasticized phenolic resin and 350 g of a fatty acid-modified alkyd resin mixed. This mixture is dissolved in 1000 g of xylene and can be used, for example, for Soaking the windings of electrical equipment can be used. These windings will be then heated to a temperature of 140 ° C. for 8 hours, after evaporation of the solvent the curing takes place through crosslinking.
Der Vorgang ist im wesentlichen der gleiche, wenn statt der oben angegebenen speziellen Stoffe ein gemischter Phenyl-Naphthylester od. dgl. verwendet wird. The process is essentially the same if instead of the above specified special substances a mixed phenyl naphthyl ester or the like. Used will.
