Abstract

The invention discloses a carbon fiber electrothermal film, which comprises at least one electrothermal layer, a plurality of electrode plate groups, an upper protective layer and a lower protective layer, the electrothermal layer is a carbon fiber layer which is formed by dipping and sizing carbon fiber monofilaments through a non-woven fabric preparation process, and sticking a sizing agent to the surface; the electrode plate groups comprise a positive pole piece and a negative pole piece, and the positive pole piece and the negative pole piece are respectively connected with the electrothermal layer electrode and bonded on the surface of the electrothermal layer; and the upper protection layer and the lower protection layer are electric insulation layers produced by a non-woven fabric preparation process, and the electrothermal layer and the electrode plate groups are combined in the middle to form a whole. The problems that in the prior art, electric leakage is likely to happen, safety is low, meanwhile, static electricity is large, electromagnetic radiation is large, and body health of people is not facilitated are effectively solved, and therefore the electric heating film isgood in safety, free of radiation, light in weight, bendable and high in heat energy conversion efficiency, adapts to application in multiple scenes and has good market popularization value.

Description

technical field [0001] The invention relates to the technical field of electric heating, in particular to a carbon fiber electric heating film. Background technique [0002] With the improvement of people's living standards and the pursuit of a better quality of life, higher and higher heating requirements are put forward. Electric heating film has entered people's lives more and more, bringing people a healthy and comfortable experience. [0003] The electric heating film in the heating market is mainly used as an electric heat source for large-area indoor heating, and is also used for local heating in industrial and agricultural production and processing, such as far-infrared low-temperature ovens, far-outline drying ovens, incubators, and indoor vegetable heating. This type of electrothermal film, such as mica heating sheet, is used in scenarios where the temperature consistency of the heating area is low, and it does not need to meet the application scenarios of cold-pr...
