Problems solved by technology

[0003] In recent years, due to the application of graphene technology, graphene electric heating film has come into life. Under the action of electric field, graphene electric heating film produces "Brownian motion" of carbon molecular groups in the heating element, and the carbon molecules react violently. The friction and impact of the friction and impact, the heat energy generated is transmitted to the outside in the form of far-infrared radiation and convection, and the action of carbon molecules makes the surface of the system heat up rapidly. The existing graphene electrothermal film has low heat conversion efficiency due to the saturation of internal carbon atoms. High, therefore, the present invention proposes the preparation method of graphene integrated heating decoration board to solve the problems existing in the prior art
