Filming accelerant solution for motor insulating varnish and filming method for insulating vanish before curing of motor

The invention relates to filming accelerant solution for motor insulating varnish and a filming method for insulating vanish before curing of a motor. The filming accelerant solution is composed of accelerant and solvent, the accelerant is nucleophilic tertiary amine, electrophilic lewis acid, lewis acid complex or metallic organic compound, and the solvent is organic solvent. The filming method for insulating vanish before curing of the motor includes the steps of treating before varnish dipping, dipping varnish, entering a spraying curing oven, spraying filming accelerant solution, curing and the like. The filming accelerant solution for motor insulating varnish and the filming method for insulating vanish before curing of the motor have the advantages that quickness in filming on the surface of the motor after vanish dipping is realized, varnish coating quantity is increased, insulating varnish loss is effectively reduced, dipping and curing time is shortened, integral density of a motor insulating structu
