Problems solved by technology

When adhesives are used for bonding, the chemical balance of the passivation film is easily destroyed, and the self-healing ability is activated. This process will easily cause the coating to fall off and affect the bonding strength of the adhesive; sometimes hydrogen gas will be generated, making the airtight A cavity is formed inside the magnetic assembly and cannot be used
At present, there is no adhesive for galvanized passivated metal bonding with reliable bonding and a strength of 20 MPa.

The shear strength of the adhesive can be up to 26 MPa.

Description

technical field [0001] The invention belongs to the field of adhesives for assembling wind power generation electromagnetic components; in particular, it relates to an acrylic adhesive for assembling wind power generation electromagnetic components, a preparation method and a use method thereof. Background technique [0002] With the increasing proportion of wind power in my country's medium and long-term renewable energy planning, permanent magnet direct drive wind turbines have been widely used in wind power generation systems due to their advantages of high efficiency, simple maintenance, and low voltage penetration. The reliability of the bonding of the permanent magnet structure of the core component of the generator set has become one of the keys to the manufacture of permanent magnet wind turbines. A wind turbine consists of a stator and rotor set, and its core structure is a magnetic assembly. At present, the fixing methods of magnetic components at home and abroad a...
