Abstract
The utility model relates to a mica tape. The mica tape comprises a reinforcing material layer, a first adhesive layer, a mica raw material layer and a second adhesive layer which are sequentially distributed in laminating mode, wherein the first adhesion layer is coated on the reinforcing material layer through a roller, the mica raw material layer is formed by adsorbing and adhering mica raw materials onto the first adhesion layer by utilizing electrostatic fields, and the second adhesion layer is sprayed on the mica raw material layer. The mica tape adopts the electrostatic field to adsorb mica powder to reinforcing materials to enable the manufactured mica raw material layer to be slightly loosened compared with a mica layer manufactured through a traditional method. When the mica tape is used for vacuum pressure paint dipping of high pressure motors, large capacity wind-driven generators, large variable frequency speed regulating electric motors and the like, insulation paint can fast and sufficiently soaked, non-air-gap insulation is achieved, and improvement of reliability and service life of the high pressure motors are facilitated.
