Embodiment 1

[0030] Electrothermal film solution raw materials (parts by weight): 48 parts of tin tetrachloride, 5 parts of titanium tetrachloride, 4 parts of nickel tetrachloride, 3 parts of zinc acetate, 3 parts of gallium trichloride, 5 parts of hydrochloric acid, 3 parts of isopropanol Parts, 28 parts of absolute ethanol.

[0031] The specific preparation steps of the electrothermal film are as follows:

[0032] (1) Configure the electrothermal film treatment solution: weigh each raw material by weight, place it in a high-speed mixing heater, heat it to 60°C, stir at a speed of 600 rpm for 4 hours, mix and stir evenly, and make the solid All dissolved, cooled to room temperature, filtered with 100-mesh filter cloth to obtain electrothermal membrane treatment solution;

[0033] (2) First wash the surface of the quartz glass with distilled water to remove the dust on the surface of the quartz glass, then put it into an ultrasonic cleaner and use ethanol to sonicate for 30 minutes. The u...

Abstract

The invention discloses a saturated solution used to prepare an electrothermal film. The saturated solution comprises a soluble tin-based chloride, titanium tetrachloride, nickel tetrachloride, a zinc dopant, gallium trichloride, a catalyst, isopropanol and absolute ethyl alcohol. According to the invention, the saturated solution used to prepare the electrothermal film has the advantages of simple preparation technology and easy quantitative doping. The electrothermal film prepared by the solution has the advantages of stable work, long service life, good substrate adhesion and high thermal efficiency.

Description

technical field [0001] The invention belongs to the technical field of semiconductor electric heating film materials, and in particular relates to a saturated solution for preparing electric heating film. Background technique [0002] Electrothermal film is widely used in various occasions and is a thin film heating material. The so-called thin film heating material is to form a layer of conductive film on the surface of the insulating material after a certain process is processed on the surface of the insulating material. Conductive particles form a network lattice structure on the surface of the insulating layer, and various additives added to the film can adjust the power of the electrothermal film. After electrification, this layer of film can be converted, so people are also called electrothermal film. [0003] The present invention adopts spray pyrolysis method to prepare thin film, and the basic principle of spray pyrolysis method preparation thin film is: use metal...
