Abstract
Disclosed are a corona-resistant N-grade insulation paper for a variable frequency motor and a preparation method thereof. The insulation paper has a sandwich structure, aramid nanofibers and mica nanosheets are taken as a sandwich material of the sandwich structure, aramid nanofibers and silicon carbide nanowires being taken as upper and lower surface layer materials, and three layers of materials are electrostatically sprayed and thermo-compressed to prepare the insulation paper. According to the present disclosure, by introducing mica sheets and the silicon carbide nanowires into the aramid nanofibers, the highly ordered arrangement inside the sandwich structure is realized through electrostatic spraying, which improves the temperature resistance and corona resistance of the insulation paper.
