Problems solved by technology

[0006] The purpose of the present invention is to solve the technical problem that the energy of the heating element in the existing electrothermal painting cannot be transferred to the decorative layer of the electrothermal painting in time. Although the temperature of the heating element rises, the far-infrared radiation efficiency on the front of the decorative layer is not high and the heating rate is slow. , providing a graphene electrothermal painting and a preparation method thereof, the graphene electrothermal painting of the present invention has high far-infrared radiation efficiency, increases the energy transfer efficiency between the heating body and the heating painting decorative layer, and improves the transmission of infrared radiation energy from the heating body Efficiency transferred to the thermal painting decorative layer, now improving the thermal painting heating and far infrared therapy effect
