Problems solved by technology

Although the electrothermal film technology of the prior art has the effect of heating, it has the following disadvantages: 1. The electrothermal film technology of the prior art is a very thick electrothermal film, so its heat source generates heat similar to linear conduction, Therefore, its heating efficiency is not good
2. The electrothermal film technology in the prior art can only be used in non-conductive and high-temperature-...

Description

technical field [0001] The invention relates to the field of coating compositions, in particular to an electrothermal coating composed of metal oxides, non-metal oxides, organic semiconductors and polymers. [0002] Background technique [0003] As we all know, the existing electrothermal film is mainly composed of graphite powder semiconductor conductive powder and inorganic film-forming agents of various oxides such as lead oxide, silicon oxide, magnesium oxide, silicon oxide and boron oxide, metal powder and water-soluble organic film-forming agent. The solvents are blended with each other to form a conductive coating. The prepared semi-conductive conductive coating is sprayed or printed, and the conductive coating is directly sprayed onto the surface of the medium that has been cleaned and dried, and then baked and dried at high temperature. After high-temperature winding treatment, the raw material of the electric heating film forms an overlapping microscopic electrifi...
