In addition, the conductive ink has the advantages of being high in heating uniformity, electricity-heat conversion efficiency and heating speed, light, good in flexibility, high in adhesiveforce, good in weather resistance and aging resistance, high in safety, environmentally friendly and the like, can be used as heating products for buildings and can also be processed into various electric heating products.

Description

technical field [0001] The invention relates to a carbon-based electrothermal coating for low-temperature radiation electrothermal film and a preparation method thereof, which belongs to the electrothermal coating technology. Background technique [0002] Electric heating film is a kind of heating system. At present, more mature electric heating methods include electric heating, electric boiler, heating cable, electric heating film and so on. Among them, the electric heating film radiant heating has the characteristics of high thermal comfort and the ability to generate infrared rays beneficial to the human body, so it has great development prospects. [0003] The heating principle of the low-temperature radiothermal film is resistance heating, the printed ink strip is equivalent to the resistance, and the metal current-carrying strip is equivalent to the resistance. [0004] As a wire, several resistors are connected in parallel. When the electric heating film is heated, ...
