Description of the invention (1) The present invention relates to a shaft for powder coating used in electric motors or generators. This shaft can also be called electron generator, it is part of the motor, and it is used as the support for winding the coil in electric motor or generator. When an electric motor or generator is operating, in addition to the motor's operation, heat energy is also generated. This thermal energy causes every part of the motor to expand, especially the coils wound around the shaft. When the motor is switched off, the motor will cool down again and the heated part will shrink. This thermal cycle often occurs repeatedly during the life of the motor. To prevent electrical contact between the shaft and the coil, the shaft and the coil are coated with an insulating material, which is usually coated. In thermal cycling, the coil close to the shaft will move a little relative to the surface of the shaft, and from the standpoint of tension, the tension on the coil allows the coil to be connected to the shaft, and this moving coil will cause wear on the coated shaft. When most of the coating on the shaft has worn away, short circuits will occur and the shaft will no longer be usable. It has been found in the past that in addition to good adhesion to the surface of the shaft, the coating also needs to have high cut-through resistance in order to provide a long life shaft of the electric motor or generator. In addition, it has been found that coating can also be used to coat stators or field coils of electric motors or generators or windings or winding-type magnetic coils. The use of powder coatings is quite advantageous when the applied metallic material has an irregular shape, such as the shaft of an electric motor or generator, for example. In addition to the well-known advantages of pollution, energy saving, resource saving and labor saving, powder coating can also make the coating layer for irregularly shaped metal objects. -4- This paper is a national standard (CNS) A4 specifications (21QX 297 public love)-593404 A7 B7 5.

The use of shaft-coated powder coatings is well known in the art, and for their good cut-through resistance, anhydride-containing powder coating compositions such as 使用 Resicoat RT ex Akzo Nobel are used today. However, in terms of the health and safety risks caused by the use of the anhydride-containing material, the use of the anhydride-containing material is not a preferred method. It has further been found that the stability of the long-term storage of these compositions can be improved. The long-term stability testing of these used and cured compositions is based on thermal resistance tests, melting points, DSC scans, and rough profiles, because when the stored composition is no longer stable, these used and cured combinations Things will go bad. U.S. Patent No. 5,449,737 discloses a urethane-modified epoxy resin coating composition, which does not describe storage stability and does not mention the cut-through resistance of the coating grease. The composition is not used for coating the shaft of an electric motor or a generator. U.S. Patent No. 4,923,910 discloses an epoxy-free epoxy coating composition which is used to fix a shaft coil of a motor and a generator to a shaft magnetic coil. In this patent, powder coating is used as an adhesive for magnetic coils. In this patent, there is no description of storage stability and no mention of cut-through resistance of coating grease. The coating composition is not used to coat the surface of the rotating shaft, and the materials disclosed in this patent applied with the powder coating composition and the material according to the present invention show poor cut-through resistance. Anhydride-free powder coating compositions have been found to have good storage stability and are also well-suited for coating in the shafts of electric motors or generators in terms of their high cut-through resistance. The composition is a temperature-controlled powder coating composition,

The two coatings just prepared are used on a rotating shaft and matured into a smooth coating film. Some of these samples were stored at 23 ° C, and then used on the rotating shaft after six months. Measure the cut-through temperature, melting point (Tm), and glass transition temperature (DSC Tgl) of 50% of the cured coating of the sample. And roughness. The results are shown in the following table: Example Fresh powder 1 23 ° C after 6 months Fresh powder with anhydride powder coating 23 ° C after 6 months 50% cut through temperature 300 ° C 300 ° C 310 ° C 260 ° C Tm 99 ° C 99 ° C 84 ° C 98 ° C DSC Tgi 69 ° C 69 ° C 63 ° C 73 ° C Roughness 5 micrometers 5 micrometers 2 micrometers> The results above 30 micrometers clearly show that the anhydride-containing combination is stored after a period of storage The properties of the material will deteriorate, and even after long storage, the composition containing the epoxy-terminated polyazolinone resin shows very good properties. -11-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)
