Problems solved by technology

The solid content of the multi-tape adhesive is only about 40%. A large amount of organic solvents volatilize after baking in the mica tape production process. The organic solvent content in the mica tape is less than 1%. The volatilization of these organic solvents not only causes waste. Increase the production cost of mica tape, and more seriously pollute the environment
[0004] How to solve the problem that a large amount of organic solvent needs to be consumed in the production process of less glue mica tape, which causes high production cost of mica tape and seriously pollutes the environment is a technical problem in this field

Embodiment 1

[0022] Example 1: Single-sided reinforced mica tape

[0023] Nanomaterials whose surface has been activated are added to mica powder, the amount of nanomaterials is 15% of the mass of mica powder; the nanomaterials and mica powder are uniformly dispersed by high-speed stirring to obtain mica raw material 3.

[0024] The nanomaterial is a mixture of 32wt% aluminum oxide and 68wt% aluminum nitride.

[0025] In order to reduce the amount of organic solvent used in the production of mica tape, when preparing the first adhesive 1, the solid content of the adhesive was controlled at 77wt%, added to the glue tank, glued with a roller and applied to the lower end surface of the reinforcing material 2 , according to the requirements of the mica tape glue content, adjust the amount of glue applied to the reinforcing material by the roller, turn on the power supply of the electrostatic generator 9, and make the mica raw material 3 and the reinforcing material be charged with opposite cha...

Embodiment 2

[0029] Example 2: Double-sided reinforced mica tape

[0030] Nanomaterials whose surface has been activated are added to mica powder, the amount of nanomaterials is 15% of the mass of mica powder; the nanomaterials and mica powder are uniformly dispersed by high-speed stirring, and mica raw material 3 is obtained.

[0031] The nanomaterial is a mixture of 40wt% aluminum oxide and 60wt% aluminum nitride.

[0032] In order to reduce the amount of organic solvent used in mica tape production, the solid content of the adhesive is controlled at 78% when preparing the adhesive, added to the glue tank, glued with a roller and applied to the lower end of the reinforcing material 2, according to the mica The content of the adhesive tape requires adjusting the amount of glue coated on the reinforcing material by the roller, and turning on the power of the electrostatic generator 9, so that the mica raw material 3 is absorbed and pasted on the reinforcing material 2; the mica raw materia...

Abstract

The invention relates to a mica tape manufacturing method suitable for energy conservation, emission reduction and reduction of environmental pollution. The mica tape manufacturing method includes adding nanometer materials subjected to surface activation into mica powder; uniformly stirring and dispersing the nanometer materials and the mica powder at high speed for standby application; coating first adhesive on a reinforced material through a drum, and adsorbing mica raw materials onto the reinforced material by means of an electrostatic field; spraying second adhesive onto the mica raw materials on the reinforced material, compositing the second layer of a reinforced material to obtain a semi-finished double-side reinforced mica tape; drying the semi-finished double-side reinforced mica tape to remove organic solvent through a drying oven, cooling and rolling the semi-finished double-side reinforced mica tape to obtain a mica roll, namely a finished double-side reinforced mica tape. The mica tape manufacturing method is a new production process utilizing natural characteristics of charge. Only by little solvent, production cost of the mica tape is reduced, and the environmental pollution of the organic solvent is greatly reduced.

Description

[0001] This application is a divisional application. The invention-creation name of the original application: a method for manufacturing mica tape, application number: 201110411241.1, application date: 2011-12-12. technical field [0002] The invention relates to the technical field of electrical insulating material manufacturing, and relates to a new manufacturing process for high-voltage generators and high-voltage motors with more or less glue mica tape, in particular to a mica tape manufacturing method. Background technique [0003] Mica tape is the most irreplaceable and critical insulating material for motors, especially large-scale, high-voltage motors, wind turbines, and large-scale variable-frequency speed-regulating motors. Mica tape is used to bond reinforcing materials and mica paper together with adhesives Cut and formed strip insulation material. During the mica tape manufacturing process, the adhesive must be dissolved into a solution with a large amount of or...
