Abstract

The invention discloses an anticorona semiconductor mica tape. The anticorona semiconductor mica tape sequentially comprises a fiber cloth layer (1), a semiconductor slurry layer (2), an adhesive layer (3) and a mica paper layer (4) from bottom to top. A preparation method of the anticorona semiconductor mica tape comprises the steps that fiber cloth is coated by semiconductor slurry, anticorona base materials which are formed by the fiber cloth layer (1) and the semiconductor slurry layer (2) are formed after the semiconductor slurry is solidified, the anticorona base materials are coated by adhesive, then mica paper is compounded, and the anticorona semiconductor mica tape is prepared after the mica paper is solidified. The anticorona semiconductor mica tape has the advantages of being excellent in anticorona performance, high in electric strength and temperature resistance grade, soft and dry after being solidified, small in thickness, high in binding force, not prone to layering, and free of carbon deposition after being combusted. The anticorona semiconductor mica tape is suitable for manufacturing coil winding wires of machines such as anticorona fireproof lifesaving wires and cables, anticorona high-speed traction motors, steel rolling motors, transformers and generators.

Description

technical field [0001] The invention relates to an anti-corona semiconductor mica tape, a preparation method and an application thereof. Background technique [0002] At present, continuous wrapping insulation is generally used for large and medium-sized motors to obtain excellent performance, and the main body of the insulation material is mica tape. With the advancement of science and technology, high-speed locomotive traction motors, rolling motors, OVDT open-type transformers and high-voltage generators have put forward higher requirements for insulating materials: frequency conversion and energy saving, high output, volume reduction, and insulation layer thickness reduction. , Anti-corona, higher electrical strength and longer service life. This kind of mica tape has no domestic and foreign manufacturers to produce it, and it involves many problems such as substrate, anti-corona treatment agent, adhesive and tape-making process. [0003] At present, most of the common...
