Preparation method of electric heating composite board and electric heating composite board

The invention discloses a preparation method of an electric heating composite board and an electric heating composite board manufactured through the method. The preparation method of the electric heating composite board comprises the steps that: S1, three or more boards are selected; S2, all the boards are arranged in parallel in an attached mode, a heating device is arranged on the surface of the middle board, the attached faces of all the boards are bonded, and all the boards are pressed through hot pressing equipment; and S3, holes are drilled in the boards, and the heating device and an external wire are connected by using a plug connector. The electric heating composite board manufactured through the method can replace a traditional electric floor heater, is simple in structure, convenient to install, low in cost, clean, environmentally friendly, free of occupying space, capable of achieving far infrared heating, warm and comfortable, and is particularly suitable for areas without unified heating in the
