Beschreibung
Zusammenfassung:	The invention discloses a corona-resistant low-shrinkage flexible insulating composite film material for a thermal power generator. The film material is characterized in that the material is a three-layer composite film material, the three layers are a corona-resistant special polyimide film outer layer, a common polyimide film middle layer, and a corona-resistant special polyimide film outer layer, and the film layers are compounded by high-temperature-resistant corona-resistant modified glue. The glue has an organic-inorganic network structure system formed by a modified corona-resistant inorganic nano-powder and polyurethane through a coupling agent, and is glue of a high-temperature-resistant grade C, wherein the high-temperature-resistant grade C means resistance to a temperature of 200 DEG C or higher. The high-temperature-resistant corona-resistant composite film material is improved in problems of large shrinkage and dimensional instability caused by bad heat resistance existing in current conventiona
