Abstract

The invention discloses a manufacturing method of an electrothermal film. The manufacturing method comprises the following steps of A, preparing an electrothermal film treatment solution which comprises tin tetrachloride, titanium trichloride, antimony trichloride, calcium chloride, chromic oxide, manganese dioxide, nickel sesquioxide, isopropanol, alcohol and water, B, masking a substrate, C, heating the substrate to be 400-700 DEG C and then spraying the electrothermal film treatment solution on the substrate by a spray gun to form a semifinished electrothermal film, D, annealing the semifinished electrothermal film, and E, coating silver oxide paste on the surfaces of the two ends of the annealed semifinished electrothermal film, loading the semifinished electrothermal film into an electrode oven, baking and fusing the semifinished electrothermal film to form a whole, and obtaining the finished electrothermal film. The manufacturing method has the advantages that the stability of the electrothermal film is improved by adding antimony; the temperature resistance of the electrothermal film is improved by adding titanium; the infrared emitting ability of the electrothermal film is improved by adding nickel and manganese; and an adhesive force between the electrothermal film treatment solution and the substrate is increased by adding isopropanol.

Description

technical field [0001] The invention relates to the field of heating materials, in particular to a method for manufacturing an electrothermal 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 also call it electrothermal film. [0003] However, the existing electrothermal film has the following problems: [0004] 1. Insufficient stability; [0005] 2. Poor temperature resistance; [0006] 3. Low infrared emissivity; [0007] 4. The adhesion is...
