Description
Es ist bekannt, Formkörper durch Umsetzen von Epoxydverbindungen, bei denen die Glycidyl-Reste an
einem Oxacycloalkyl-Rest gebunden sind, mit mehrwertigen
Aminen bei höheren Temperaturen herzustellen. Hierbei wurde insbesondere eine 2,5 - Bis-(2,3
- Epoxypropoxymethyl) - tetrahydrofuran - Verbindung verwendet. Die damit hergestellten Produkte
lassen jedoch vor allem hinsichtlich des Widerstandsvermögens gegen eine Hitzeverformung noch Wünsche
offen. ίο
Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Formkörpern oder Überzügen auf
der Basis von Polyaddukten durch Umsetzen einer Epoxydverbindung, bei der die Glycidylreste an einem
Oxacycloalkyl-Rest gebunden sind, mit mehrwertigen Aminen bei einer Temperatur zwischen 20 und 250° C,
das dadurch gekennzeichnet ist, daß als Epoxydverbindung Glycidyl - 3,4 - dihydro -1,2 - pyran - 2 - carboxylat
verwendet wird.
Durch das erfindungsgemäße Verfahren werden Polyaddukte mit einem außergewöhnlichen Widerstandsvermögen
gegen eine Hitzeverformung und hauptsächlich für eine Verwendung bei der Herstellung
von Hochtemperatur-Schichtstoffen, -Klebstoffen, -Formungen und -Oberflächenüberzügen erhalten.
Die Produkte, die unter Verwendung von mehrwertigen Aminen erhalten werden, sind vernetzte, unlösliche,
nichtschmelzbare Polyaddukte mit vielen hervorragenden Eigenschaften und insbesondere mit
einem hervorragenden Widerstandsvermögen gegen eine Hitzeverformung. Auf diese Weise hergestellte
Polyaddukte besitzen eine Hitzeverformungstemperatur von mehr als 267° C. Solche Produkte sind für eine
Verwendung bei der Herstellung von Hochtemperatur-Schichtstoffen, -Formungen, -Klebstoffen und -Oberflächenüberzügen
geeignet.
Die im erfindungsgemäßen Verfahren verwendete Epoxydverbindung ist das Glycidyl-3,4-dihydrol,2-pyran-2-carboxylat.
Die bevorzugten Amine sind aromatische, aliphatische und cycloaliphatische mehrwertige Amine, von
denen beispielsweise m-Phenylendiamin, m-Xylylendiamin
als aromatische Amine, Triäthylendiamin und Di-(hexamethylen)-triamin als aliphatische Amine und
1,3-Diaminocyclonexan oder !,S-Diaminomethylcyclohexan
als cycloaliphatische Amine erwähnt seien.
Die im erfindungsgemäßen Verfahren verwendete Ausgangsmischung kann auf beliebige, an sich bekannte
und geeignete Weise hergestellt werden. Sind beide Komponenten Flüssigkeiten, dann kann die
Mischung einfach durch Vermischen der beiden miteinander hergestellt werden. Ist eine oder sind mehrere
der Komponenten eine dicke Flüssigkeit oder eine feste Substanz, dann werden die Komponenten im allgemeinen
vorzugsweise in einem geeigneten Lösungsmittel oder Verdünnungsmittel miteinander vereinigt.
Im allgemeinen werden vorzugsweise verschiedene Lösungsmittel oder Verdünnungsmittel verwendet, die
vor oder während des Erhitzens verdampfen.
Das gegenseitige Verhältnis der Epoxydverbindung und des mehrwertigen Amins in der Mischung variiert
innerhalb bestimmter Grenzen in Abhängigkeit von den gewünschten Eigenschaften der erhaltenen Produkte.
Mischungen mit gewünschten Eigenschaften werden erhalten, wenn das mehrwertige Amin in einer
chemisch äquivalenten Menge verwendet wird, die von ungefähr 0,8 bis 1,5 pro Äquivalent der Epoxydverbindung
variiert.
In diesem Zusammenhang bedeutet eine chemische Äquivalentmenge die für die Bereitstellung eines
Aminowasserstoffes pro Äthylengruppe in Nachbarschaft zum Heteroatom benötigte Menge.
Auf Wunsch können in an sich bekannter Weise andere Substanzen, wie bekannte Füllstoffe, Farbstoffe,
Weichmacher, Stabilisatoren, zugesetzt werden.
Die Reaktion der oben beschriebenen Mischung kann durch Erhitzen herbeigeführt werden. Die hierfür
benötigte Temperatur variiert von ungefähr 90° C bis zu 25O0C.
Zur Beschleunigung der Reaktion können Katalysatoren zugesetzt werden.
Für die Anwendung des erfindungsgemäßen Verfahrens zum Überziehen kann die erfindungsgemäß
verwendete Mischung als solche oder im Gemisch mit verschiedenen Zusatzstoffen, wie Weichmacher, Stabilisatoren
und Streckmittel, verwendet werden und anschließend als Film verteilt und bei der gewünschten
Temperatur umgesetzt werden. Das erfindungsgemäße Verfahren kann ebenfalls für die Herstellung von Einbettungen
und Formungen für elektrische Geräte angewendet werden. Entsprechend der gegenwärtigen
Praxis wird die Ausgangsmischung gewöhnlich mit den gewünschten Füllstoffen, Weichmachern usw.
vereinigt und das Gemisch in die Form oder den Formling gegossen, in denen das elektrische Gerät enthalten
ist, wie etwa elektrische Motoren u. dgl. Das Gemisch wird dann auf die gewünschte Temperatur erhitzt.
Die nach dem erfindungsgemäßen Verfahren hergestellten Produkte können ebenfalls für die Herstellung
von Klebstoffen und Imprägnierungen verwendet werden.
Das erfindungsgemäße Verfahren ist weiterhin besonders nützlich und wertvoll bei der Herstellung von
Schichtstoffen oder harzartigen Gegenständen, die mit Fasertextilstoffen verstärkt sind. Wenn auch im allgemeinen
hierfür vorzugsweise Glasgewebe verwendet werden, so können doch auch beliebige andere und
geeignete Faserstoffe in Schichtform, wie etwa Glasmatten, Papier, Asbestpapier, Mikaflocken, Baumwollwatte
und Leinwand, verwendet werden.
Die erhaltenen Schichtstoffe sind hart und zäh und besitzen ein ausgezeichnetes Widerstandsvermögen
gegen eine Verformung bei hoher Temperatur.
Beispiele 1 bis 6
Im folgenden werden die Ansätze, die Reaktionstemperatur und die Reaktionsdauer zusammen mit den
Eigenschaften der erhaltenen Polyaddukte in einer Tabelle wiedergegeben.
