Abstract
Official abstract text for this publication.
Various embodiments of the teachings herein include a cationic tape accelerator for use in a process for producing an insulation system by impregnation and/or encapsulation with an anhydride-free impregnating agent. The tape accelerator comprises an ionogenic compound of a sulfonium-containing cation and a hexafluoroantimonate anion.
First claim
Opening claim text (preview).
What is claimed is: 1. A cationic tape accelerator for use in a process for producing an insulation system by impregnation and/or encapsulation with an anhydride-free impregnating agent, the tape accelerator comprising: an ionogenic compound of a sulfonium-containing cation and a hexafluoroantimonate anion; wherein the sulfonium-containing cation comprises a substituted aryl group comprising a phenyl ring which is acetyloxy-substituted. 2. The tape accelerator as claimed in claim 1 , wherein the sulfonium-containing cation includes an arylalkylsulfonium cation. 3. The tape accelerator as claimed in claim 1 , wherein the sulfonium-containing cation includes a dialkylarylsulfonium cation and/or a diarylalkylsulfonium cation. 4. The tape accelerator as claimed in claim 1 , having the following chemical structure: 5. A solid insulation material comprising: a barrier material; a tape adhesive; and a tape accelerator comprising an ionogenic compound of a sulfonium-containing cation and a hexafluoroantimonate anion; wherein the sulfonium-containing cation includes a substituted aryl group comprising a phenyl ring which is acetyloxy-substituted. 6. The solid insulation material as claimed in claim 5 , wherein the barrier material comprises platelets. 7. The solid insulation material as claimed in claim 4 , further comprising a carrier. 8. The solid insulation material as claimed in claim 7 , wherein the carrier comprises a weave, a nonwoven, a film, and/or a perforated film. 9. The solid insulation material as claimed in claim 5 , wherein the tape adhesive includes a thermoplastic polyvinylacetal and/or a liquid polyester with hydroxy groups and/or carboxyl groups. 10. The solid insulation material as claimed in claim 9 , wherein the tape adhesive includes a polyvinylacetal based on butyraldehyde and/or acetaldehyde. 11. An insulation system comprising: a winding of a solid insulation material impregnated with an anhydride-free impregnating agent comprising: a barrier material; a tape adhesive; and a tape accelerator comprising an ionogenic compound of a sulfonium-containing cation and a hexafluoroantimonate anion; wherein the sulfonium-containing cation includes a substituted aryl group comprising a phenyl ring which is acetyloxy-substituted. 12. An electrical machine comprising an insulation system as claimed in claim 11 .
