Background
With the continuous increase of wind power proportion in the middle-long term planning of renewable energy sources in China, the permanent magnet direct-driven wind power generator has the advantages of high efficiency, simple maintenance, low voltage penetration and the like, is widely applied to wind power generation systems, and the reliability of bonding of a permanent magnet structure of a core component of a motor set becomes one of the keys of manufacturing the permanent magnet wind power generator. The wind driven generator is composed of a stator and a rotor which are sleeved together, and the core structure of the wind driven generator is a magnetic assembly. At present, the fixing mode of the magnetic assembly at home and abroad is mainly fixed on the inner wall of the rotor after being assembled by an adhesive, the method has low requirements on the processing precision of the magnetic pole and the magnetic yoke, the cost is low, the method is simple, the structure of some parts can be simplified by adopting an adhesive bonding process in the assembly of parts, the structure of the whole motor can be even simplified, and the stress distribution at the adhesive bonding position is more uniform than that of screw connection, so that the motor can reliably work under vibration and impact load. With the development of rare earth permanent magnet motors in the wind power field, high-performance permanent magnet material neodymium iron boron materials are becoming the mainstream of industry application gradually. Although the performance of the neodymium iron boron material is excellent, the neodymium iron boron material is extremely active, so that the surface of the neodymium iron boron material is protected by adopting a chromic acid passivation method after galvanization. Thus greatly increasing the bonding difficulty.
The galvanized layer on the surface of the wind power generation magnetic component is passivated by chromate to form a homogeneous galvanized layer passivation film, and the passivation film is in a reversible chemical equilibrium state and has self-repairing capability. When the adhesive is used for bonding, the chemical balance of the passivation film is easily damaged, the self-repairing capability is started, the plating layer is easily caused to fall off in the process, and the bonding strength of the adhesive is affected; hydrogen is sometimes generated, so that a cavity is formed in the airtight magnetic assembly, and the airtight magnetic assembly cannot be used. At present, no adhesive for bonding galvanized passivation metals, which is reliable in bonding and has the strength reaching 20MPa, exists.

The beneficial effects of the invention are as follows:
the invention relates to an acrylic ester adhesive for assembling a wind power generation magnetic component, which is used for bonding zinc plating passivation films, wherein the zinc plating passivation films are used for chromic acid passivation treatment on zinc plating metals. This chemical reaction is a complex series of chemical reactions carried out at the interface of the metallic zinc coating and the passivation treatment liquid, the main reaction of which is generally considered to be the oxidation-reduction reaction between metallic zinc and the ions of acid groups containing hexavalent chromium. Zinc is used as a reducing agent to reduce hexavalent chromium to trivalent chromium, and the main reaction is as follows:
2CrO 4 2- +3Zn+16H + →3Zn 2+ +2Cr 3+ +8H 2 O
in addition, the following reactions are present:
Zn+2H + →Zn+H 2
reaction consumption H + The pH value at the metal interface is raised, and the oxidizing property of hexavalent chromium is reduced. When the pH value rises to a certain value, the reaction enters a chemical equilibrium state, and a passivation film is separated out on the interface. And the initiation system of the conventional acrylic adhesive is an acidic redox system. When the adhesive contacts the bonding surface of the galvanized passivation film, chemical equilibrium is broken, so that the plating layer is separated, hydrogen can be generated, bubbles are formed in a closed bonding environment, and bonding performance is affected; the assembly of the wind power electromagnetic assembly is a closed system, and if bubbles are generated during bonding, the appearance of the product is out of tolerance, and the wind power electromagnetic assembly cannot be installed and used.
According to the acrylate adhesive for assembling the wind power generation electromagnetic assembly, the dosage of the stabilizer is increased in an adhesive curing system, and is usually 0.1-0.2%, and the dosage is 0.3-0.5%, so that the adhesive is prevented from oxidizing a passivation film. However, the increase of the stabilizer can affect the curing of the adhesive to reduce the strength, so that the use amount of the accelerator in the system is increased by 0.5-5%, and the negative influence caused by the increment of the stabilizer is compensated by 8-10%, thereby ensuring the curing stability of the adhesive.
According to the acrylate adhesive for assembling the wind power generation electromagnetic component, the reaction activity of the adhesive is reduced by adding a large amount of stabilizer and reducing the amount of initiator, so that the adhesive is prevented from chemically reacting with the passivation film of the metal galvanized layer; by adding a large amount of accelerator, the curing of the adhesive is ensured to be carried out smoothly; by adding the coupling agent, the adhesive force between the adhesive and the adhered material is improved.
The acrylic ester adhesive for assembling the wind power generation electromagnetic component has the maximum shearing strength of 26MPa and the peeling strength of 4.137N/mm.
