Problems solved by technology
However, most of the resistance materials used in electric heating products are thin wires with a diameter of 0.1-5.0 mm, and the electric heat generated by them is often confined in the tiny resistance wires, and cannot be efficiently output to the external environment that requires heat.
This is easy to cause the local temperature of the resistance wire to be too high, but the external environment cannot get enough heat.
Therefore, the core factor restricting the energy efficiency of electrothermal technology is not the conversion rate of electric energy to heat energy, but the output and conduction efficiency of electric heat energy. No effective solution has been found for this problem.

Abstract
The invention relates to an electric heating coating for interface energizing and interface heating and a preparing method of the electric heating coating. The electric heating coating is characterized by being composed of a solvent, a conductive material, an additive and a binder. During preparing, the mixture of the solvent, the conductive material, the additive and the binder is stirred fully, thick liquid mixing is carried out, and pulp is obtained. Then, a substrate is coated with the pulp, and a base material is acquired. Lastly, the base material is dried to the constant weight, and the coating is acquired. The electric heating coating is used during interface energizing and interface heating, the effective heating area can be increased, the heating uniformity is enhanced, heat can be efficiently conducted and output to the specific position, and accordingly the overall energy efficiency of an electric heating component is improved. Meanwhile, the electric heating coating can carry out heating and warming on a large area under the condition of low voltage such as the voltage with the power ranging from 0.5 volt to 5.0 volts electromagnetic radiation does not exist, and the electric heating coating is suitable for portable and wearable electric heating components with batteries as a power source, and is used for outdoor sites and sites with no fixed power source.
