Embodiment 1

[0022] The carbon crystal composite filler with a whisker growth temperature of 800 ° C is coated on the sensor array film in proportion, and the electrodes are poured. The sides of the two films with the carbon crystal coating are facing each other, sealed around, and the heating effect is tested by electricity.

Embodiment 2

[0024] The carbon crystal composite filler with a whisker growth temperature of 1000°C is coated on the sensor array film in proportion, and the electrodes are poured. The sides of the two films with the carbon crystal coating are facing each other, sealed around, and the heating effect is tested by electricity.

Embodiment 3

[0026] The carbon crystal composite filler with a whisker growth temperature of 1200°C is coated on the sensor array film in proportion, and the electrodes are poured. The sides of the two films with the carbon crystal coating face each other, and the surroundings are sealed, and the heating effect is tested by electricity.

Abstract

A preparation method of a flexible carbon crystal electric heating film, relating to a preparation method of an electric heating film, the preparation of carbon crystal powder: put the chopped carbon fiber raw material into the thinner prepared according to the weight ratio and soak for 2 hours, and then put it into a vacuum drying box Baking at 80°C until the thinner material is completely volatilized; put the obtained material into a planetary ball mill for ball milling to obtain carbon crystal powder; impregnate the surface of the carbon crystal powder with Fe(OH) 2 Solution, after drying at 80°C, flow hydrogen at 600°C for 40 minutes, and then at 800, 1000, 1200°C 2 h 2 and N 2 Keep in the gas atmosphere for 20 minutes; coat the carbon crystal composite filler with a whisker growth temperature of 800°C on the sensor array film in proportion, pour electrodes, and put the sides of the two films with the carbon crystal coating facing each other. Seal it and that's it. The process of the invention is simple and effective, and the heating effect of the electrothermal film is excellent.

Description

technical field [0001] The invention relates to a preparation method of an electric heating film, in particular to a preparation method of a flexible carbon crystal electric heating film. Background technique [0002] Since the beginning of the 21st century, with the energy crisis, the aggravation of environmental pollution and people's increasing requirements for heating conditions, the disadvantages of traditional heating methods such as waste of energy, uneven charging, and inaccurate measurement have gradually emerged. Expensive electric heating has become a major development direction in the future. The more common electric heating methods include metal or ceramic electric heating devices such as electric heaters, heating cables, and electric heating ceramic sheets. However, the traditional metal resistance wire has a high density and low electrothermal conversion efficiency; the ceramic heating plate heats up slowly and is brittle. Polymer electrothermal materials su...
