Problems solved by technology

The heating tools that people use now are generally resistance wires, etc. This heating tool has the hazards of electromagnetic radiation during the heating process. In addition, the heating and heat dissipation area of ​​the resistance wire is small, and the thermal efficiency is low; in addition, the resistance wire is made of metals such as copper and aluminum. It is easy to cause waste of metal, and the resistance wire is heated for a long time, which is prone to oxidation and affects the service life

Abstract

The invention provides an electrothermal film and a preparation method thereof. The electrothermal film is prepared from the following components in parts by weight: 85 to 100 parts of stannic chloride, 3 to 6 parts of antimony butter, 2 to 4 parts of titanium tetrachloride, 2 to 5 parts of ferric trichloride, 1 to 3 parts of bismuth trichloride, 10 to 15 parts of hydrochloric acid, 20 to 30 parts of isopropyl alcohol, 20 to 40 parts of methanol and 50 to 80 parts of absolute ethyl alcohol. All the components are weighed and mixed to obtain a stock solution of the electrothermal film; the stock solution of the electrothermal film is sprayed to the surface of a base material by adopting the metal salt solution spray pyrolysis method. The electrothermal film and the preparation method thereof have the advantages and the active effects that the electrothermal film is high in heating efficiency; the film forming speed can reach 80nm / min; the preparation method is suitable for manufacturing of a large-area film and large-scale production.

Description
