Anticorona varinish is generally mixed, is mainly used for by insulating varnish and non-metal conductor (carbon black, graphite etc.) powder
High-tension coil makees anticorona varinish, as the higher end turn of voltage in large high-voltage motor.Industrially require anticorona varinish
Surface resistivity is stable, adhesive force is strong, wearability is good, rate of drying is fast, shelf-stable, anticorona varinish can individually be coated in coil table
Face can also be coated in asbestos yarn, on glass tape, in wrapping in coil outer layer, or be coated on glass cloth and major insulation one-pass molding.
One trend of generator development is that voltage class is higher and higher, and capacity is increasing, especially large-scale air cooling machine
Group, this puts forward new requirements stator winding anticorona material, and not only single stator bar discharge inception voltage requires higher, and
Stator winding cannot in the process of running due to corona act on and end scaling loss.Meet this requirement a kind of method be exactly
One layer of high resistance anticorona varinish of bar end surface brushing after molding, and one layer of high resistance is sprayed on stator winding end surface
Anticorona varinish.
Current high resistance anticorona varinish that is domestic and using is the dry high resistant anticorona varinish of one-component gas, and paint base is epoxy-ester
Or polyesters gas dried lacquer, they seal container and condition of storage requirement is high, and storage life is short.Simultaneously as be gas dried lacquer,
If overweight coating, or be sprayed on the surface of adsorptivity, then the extremely difficult solidification of bottom anticorona varnish, required curing time is long,
To extreme influence bar or the adhesion and anti-corona performance on winding surface.
Therefore, inventing a kind of fast and not easily to fall off anticorona varinish of speed has positive effect to technical field of coatings.
Summary of the invention
Present invention mainly solves the technical issues of, for easy in external carbon black, graphite composite powder in current anticorona varinish
It falls off, influences its anticorona performance, while its required curing time is long, influences the defect of its adhesive force, provides one kind
The preparation method of rapid curing peel type anticorona varinish.
