[0046] Example: see figure 1 , figure 2 with image 3 , a method for preparing a wound iron core provided by the present invention, which includes a strip-shaped non-oriented magnetic material 11, comprising the following steps:
[0047] (1) Preparation of mixed insulating paint 12: for uniform coating on the surface of the non-oriented magnetic material 11, so as to fully fill into the tiny gaps produced by the deformation of the non-oriented magnetic material 11, and penetrate into the non-oriented The inside of the magnetic material 11, and the non-oriented magnetic material 11 can be siliconized during the high temperature treatment process;
[0048] The specific steps are as follows:
[0049] (11) Preparation raw materials:
[0050] Prepare material A: prepare silicon oxide with a particle size of 1800-2200 mesh;
[0051] Prepare material B: prepare aluminum dihydrogen phosphate with a particle size of 1800-2200 mesh;
[0052] Preparation of material C: preparation...
