Embodiment

[0027] Embodiment: a kind of transparent heating film, adopts following formula:

[0028] InCl 3 : 5.2 grams;

[0029] SnCl 4 5.2 grams;

[0030] BiCl 3 : 5.2 grams;

[0031] HCl: 100 ml;

[0032] Methanol: 450 ml;

[0033] Water: 460ml.

[0034] The following manufacturing methods are used:

[0035] (1) Take InCl 3 52 g, SnCl 4 ·5H 2 O 5.2 g, BiCl 3 5.2 grams, 450ml of methanol, pour the above four substances into container A, mix and stir evenly, take 100ml of HCl, and pour 460ml of water into container B, mix and stir evenly, then slowly pour the solution in container B into the container In A, stir slowly and evenly at the same time, and use it as a substrate for spraying film;

[0036] (2) Production of the cover layer: the function of the cover layer is to block the part that does not need to be sprayed with the heating film, take 200g of large stone powder, 20ml of M1 water-soluble glue, H 2 O 200ml Put these three substances in a container, mix and stir ...

Abstract

The principle of the method is: chloride is used to make hydrolyzing reaction on the high temperature base material surface for forming a transparent and conductive metal oxide-InO2 film; in the process of forming the film, SnCl4+5H2O and BiCl2 is are used as doping agent of InO2 heating film to improve the conductance and thermal stability of the heating film; carbinol is used as main solvent.

Description

technical field [0001] The invention relates to a transparent heating film used in an electric heating device and a manufacturing method thereof. Background technique [0002] At present, the electric heating elements used by people are generally electric heating alloy wires, electric heating tubes, etc. When this kind of electric heating element is working, because its own heating area is relatively small, and it cannot be in close contact with the object to be heated, the heat generated by it cannot be quickly conducted to the object to be heated, so that the electric heating element The heat on the surface is too concentrated and will soon become hot, causing a part of the heat to be converted into light energy and lost. Therefore, its thermal efficiency is very low, especially when heating objects with slow heat transfer such as glass and ceramics, the distribution of electrothermal alloy wires and electric heating tubes is uneven, and its thermal efficiency is even low...
