[0033] Correspondingly, an embodiment of the present invention also provides a method for preparing the above-mentioned filling glue for the covering film of the wireless charging coil. The method comprises the steps of:
[0034] S01: Weigh each component according to the above-mentioned filling glue for the wireless charging coil diaphragm;
[0035] S02: Mixing the weighed modified epoxy resin, accelerator, dye, and matte powder to obtain a first mixed material;
[0036] S03: placing the first mixed material in a high-speed disperser for dispersion treatment to obtain a second mixed material;
[0037] S04: Filtrating the second mixed material to obtain the filling glue.
[0038] Specifically, the preferred contents and types of each component of the filler used for the wireless charging coil diaphragm in the above step S01 are as described above, and will not be repeated here to save space.
[0039] In the above step S02, the mixing process can be carried out in a conventi...
