NOVELTY - The method involves mixing graphite, carbon crystal, carbon black, graphene and auxiliary agent, stirring, grinding and curing to obtain slurry, where the auxiliary agent comprises agglomerant, diluent, anti-settling agent, heating agent and antifoaming agent, adhering a base material on the insulating material to obtain the substrate, printing the slurry on the substrate, drying the semi-finished product material, obtaining the dried semi-finished product material, and packaging the dried semi-finished product material to obtain an organic nano high temperature resistant electrothermal film. USE - Method for preparing organic nano high temperature resistant electrothermal film including electric blanket, electric heater, electric hair dryer, and physical therapy instrument. ADVANTAGE - The organic nano high temperature resistant electrothermal film has good conductivity, high heat conductivity coefficient, large heat radiation intensity, high temperature resistance and aging resistance, and can work normally for a long time. The method is non-toxic, tasteless, pollution-free, clean and environmentally-friendly, and saves 20%-30% by high-efficiency heating performance, realizes the electric heating conversion clean energy, and releases a lot of infrared rays beneficial to the human body, and has high insulating protective layer when packaging, and ensures the safety of human body near the distance of the heating and physical therapy, and is very safe.
