Abstract

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 structure is improved, and accordingly insulating strength of the motor can be effectively improved, and the service life of the motor is prolonged.

Description

technical field [0001] The present invention relates to a film-forming accelerator solution of motor insulating varnish and a film-forming method of insulating varnish before motor baking. A film-forming accelerator solution belongs to the technical field of motor manufacturing. Background technique [0002] With the development of science and technology, environmental protection regulations and the continuous enhancement of human environmental awareness, people pay more and more attention to the harm of organic volatiles in insulating paint to human health. In the motor itself and motor manufacturing, the research on reducing the emission of organic solvents in insulating varnish is very necessary, and it has been paid more and more attention by the insulation industry. The diluent (generally styrene) selected for the existing insulating varnish volatilizes in a large amount during baking, which is not good for environmental protection, and is also harmful to operators to ...
