Abstract

The invention provides a saturated solution for preparing an electrothermal film. The saturated solution is formed by tin tetrachloride, titanium tetrachloride, cobaltic chloride, gallium trichlorideand ethylene glycol. The mass percentage of the tin tetrachloride in the saturated solution is 30%-40%; the mass percentage of the titanium tetrachloride in the saturated solution is 10%-20%; the masspercentage of the cobaltic chloride in the saturated solution is 10%-20%; the mass percentage of the gallium trichloride in the saturated solution is 10%-20%; and the mass percentage of the ethyleneglycol in the saturated solution is 20%-30%. The invention also provides a preparation method of the saturated solution. The preparation process of the saturated solution is simple; and the prepared electrothermal film is high in heat energy conversion efficiency, uniform in heating, long in service life and low in cost.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a saturated solution, in particular to a saturated solution for preparing an electric heating film and a preparation method thereof. Background technique [0002] China is the main production base of electric heating appliances in the world, with an annual output of more than 50 million KW of household electric heating components, accounting for 60% of the world's total production of electric heating products; before, the main electric heating components of electric heating products were semiconductor ceramic materials, namely PTC materials, but PTC materials contain lead elements, which will cause harm to the human body and the environment during use, and the heat conversion efficiency is not high, so they are gradually eliminated by the market. [0003] At present, the saturated solution used to prepare the electrothermal film is likely to cause harm to the human body and the oper...
