The invention provides a 3D glass cover plate, a preparation method thereof and an electronic product, the preparation method comprises the following steps: providing a 3D glass cover plate, the concave surface, the convex surface and the side wall of the 3D glass cover plate are all provided with coating layers, the concave surface and the convex surface are both provided with uncoated channels, and the channels divide the coating layers on the concave surface and the convex surface into a plurality of parts; the coating layer on the side wall corresponding to the channel is removed through laser, and a side wall removal area is formed; the channels of the concave surface and the convex surface are communicated through the side wall removal area, so that the coating layers of a plurality of parts on the concave surface and the convex surface are mutually independent; when the side wall coating layer is removed, an included angle is formed between the plane where the edge of the concave face of the cover plat
