Abstract

L'invention concerne un ruban isolant pour l'isolation de bobines de stator dans des machines électriques, notamment l'accélérateur contenu dans l'adhésif du ruban isolant qui est utilisé pour un système d'isolation à ruban enroulé. Les accélérateurs connus jusqu'à présent, à base de N-éthylpipérazine, sont ici remplacés par des composés imidazole et/ou pyrazole. Dans d'autres exemples de modes de réalisation de l'invention, le champ d'application de ces composés d'imidazole et/ou de pyrazole, dont on a découvert une nouvelle utilisation pour cette technique, est élargi car ils peuvent être utilisés sous la forme d'agents gélifiants et/ou d'agents durcisseurs généralement dans des résines époxydiques à base de diglycidyléther de bisphénol A et/ou de diglycidyléther de bisphénol F, notamment les types exempts d'anhydride phtalique.
