Problems solved by technology

[0003] Most of the traditional epoxy resin coating materials are two-component systems, which need to be used and prepared immediately, which brings inconvenience to the construction site (Zhao Hui, Chen Zhiming, Wang Qiuying, Wu Xia. Modified imidazole latent epoxy resin Preparation of Curing Agent[J]. Coating Industry, 2004, 7:23-25)
Moreover, the existing single-component silicon steel sheet paint has poor stability, and the hardness and heat resistance level of the paint film also need to be improved.
[0004] In addition, the adhesion or bonding performance between the existing silicon steel sheet paint film and the silicon steel sheet is not good enough, the adhesion effect is not good enough, and the leveling performance is poor, resulting in a large paint film thickness and a small lamination coefficient of the iron core
[0005] Moreover, most of the existing silicon steel sheet paints are added with organic solvents, which have peculiar smell and even toxicity

Description

Technical field [0001] The present invention relates to the field of aqueous coatings, and more particularly to a single part of a water-based silicon steel sheet, covering the surface of the silicon steel sheet to insulation protection, particularly suitable for large generators, silicon steel sheets of the motor. Background technique [0002] Silicon steel sheets are used for motor, transformer core, to reduce eddy current loss of core, enhance rust and corrosion resistance, and need to be coated with silicon steel sheet using insulating paint. As an insulating paint, it should have good dielectric properties, oil resistance, moisture-proof sex, strong adhesion, and sufficient mechanical strength and hardness. In addition, the paint film is as thin as much as possible in the premise of satisfying performance, to increase the axonal coefficient of the core, increase the effective length of the core. [0003] Most of the traditional epoxy coating materials are two-component syste...
