Problems solved by technology

[0004] In the matching of components, there is also too much "doping", or the purity of the components is poor, and the impurities increase, which makes it difficult to control the chemical reaction and affects the quality of the electrothermal film.
[0005] Therefore, the electrothermal film made by the prior art has poor chemical stability, is not resistant to high temperature, is not suitable for dry burning, has unstable conductivity, and has a short service life.

Abstract

A high temperature, multifunctional inorganic electrothermal membrane, its characteristic is that it is composed of SnCl4 400-500, InCl3 60-100, SbCl3 10-30, MnCl2 1-5, NiCl2 1-5, C2H5OH 400-600,C3H5(OH) 360-120 according to weight proportion. All the above-mentioned compositions don't contain moisture or crystalloid water, and mustn't add deionized water as diluting solvent. All the mentioned compositions are analytic pure materials. Compared with present technique, the advantages are high thermal efficiency, temperature resistance, antioxidant, steady conductance, long service life and wide application.

Description

technical field [0001] The invention relates to an electric heating film, in particular to a high temperature resistant inorganic electric heating film and a manufacturing method thereof. Background technique [0002] As early as the 1950s, there were reports about SnO in foreign countries 2 ·Report of Sb semiconductor electrothermal coating. In the 1970s and 1980s, my country strengthened the research in this area. For example, in the public documents of Chinese patent application numbers 88108194, 89107751, 92106609, etc., relevant discussions were recorded. Among the components of the above-mentioned electrothermal coating, all include stannous chloride (SnCl 2 2H 2 O) or tin tetrachloride (SnCl 4 ·5H 2 O) aqueous solution as the main raw material, antimony trichloride (SbCl 3 ) is a dopant substance, which is hydrolyzed at high temperature and oxidized by water to obtain a layer of SnO 2 ·Sb semiconductor electrothermal film. However, the above-mentioned semicond...
