Problems solved by technology

[0004] The electric heating film that has been widely used in the market generates uneven heat after being energized, and the electric heating film is prone to sparking, the resistance is unstable, it is easy to attenuate, and it is easy to accumulate heat. The wavelength and frequency of infrared rays of this type of product are unstable, and the peak value is small and cannot be adjusted.
The heating temperature of the traditional electric heating film is uneven, the heating efficiency is low, and the power of the electric heating film will attenuate during use, the temperature resistance is weak, and the working life is relatively short

Abstract

The invention discloses a preparation process of an infrared electric heating film, which comprises the following steps: (1) configuring an electric heating film treatment solution; (2) substrate pretreatment; (3) spraying plastic; (4) annealing a semi-finished electric heating film; (5) After the silver oxide silver paste is applied, it is sent to the electrode furnace to be baked and fused. In the present invention, high radiation oxides are added to the raw materials of the electrothermal film treatment solution, which can improve the thermal radiation performance of the electrothermal film, so that the film layer has a higher full-wavelength emissivity; adding cerium oxide and cordierite, can improve the film The anti-shock performance of the film layer can prevent the film layer from falling off; at the same time, the addition of silicon dioxide can enhance the heat dissipation performance of the film layer and improve the heat resistance of the film layer; the preparation process of the present invention is simple and easy to operate, and the prepared infrared electric heating film has excellent Excellent electrothermal conversion performance and long service life.

Description

technical field [0001] The invention belongs to the technical field of preparation of electrothermal film products, and in particular relates to a preparation process of an infrared electrothermal film. Background technique [0002] The electric heating film is a heating system, which is different from the point heating system represented by radiators, air conditioners, and radiators, and the line heating system represented by heating cables. It adopts modern aerospace technology in the field of surface heating. The research and development of low-carbon heating high-tech products, and its advantages of emitting far infrared rays, etc., are increasingly attracting people's attention. [0003] The existing electrothermal films are roughly divided into four types, namely: printing ink type, ultra-thin metal sheet type, carbon fiber type and functional polymer electric heating new material type. Different electrothermal films have different technical contents and have different...
