Abstract

The invention provides a preparation method of a transparent tin antimony oxide electric heating film, which belongs to the field of thin-film materials. The preparation method comprises the steps that tin and antimony raw materials and an additive are dissolved in a solvent to form a solution; a pH value of a system is adjusted to be neutral or slightly alkaline; the solution is put in an ultrasonic atomizer; a nozzle of the ultrasonic atomizer is positioned at the top of an electric box furnace; glass tubes or ceramic tubes to be coated are placed on a rack orderly and vertically; the rack on which the glass tubes or the ceramic tubes are placed is placed in the electric box furnace; a door of the electric box furnace is closed; the electric box furnace is switched on; the ultrasonic atomizer is switched on; and drops of the solution containing tin and antimony are deposited on the external surfaces of the glass tubes or the ceramic tubes uniformly to form transparent tin antimony oxide conductive films. The glass tubes or the ceramic tubes coated with the transparent tin-antimony oxide conductive films can be used as heating elements for heating liquid, gas, solid and the like.

Description

technical field [0001] The invention provides a method for preparing a tin antimony oxide transparent electrothermal film, which belongs to the field of thin film materials. Background technique [0002] The electric heating film is an electric heating element that directly converts electric energy into heat energy. It is a layer of conductive film attached to the surface of insulating materials such as enamel, glass, ceramics and plastics. After it is energized, it can convert electrical energy into heat energy by using the principle of resistance heating. Like electric heating tubes, electric heating rods, electric heating plates, electric heaters, rice cookers, induction cookers, etc., it is an integral part of the huge family of electric heating products. Metal tin oxide electrothermal film material has surface heating, high electrothermal conversion efficiency, no open flame, corrosion resistance, wear resistance, small size, light weight, strong heat release capacity,...
