Graphene electric heating metal composite plate

Abstract

The invention discloses a graphene electric heating metal composite plate. The device comprises an upper metal plate, a graphene electrothermal film, a reflective film layer, a heat preservation and insulation plate and a lower metal fixing plate; the upper metal plate and the lower metal fixing plate are connected into a whole through the foamed heat preservation and insulation plate; the graphene electrothermal film and the reflective film layer are overlaid and located between the upper metal fixing plate and the lower metal fixing plate and are wrapped by the heat preservation and insulation plate; the graphene electrothermal film is located above the reflective film; the upper end face of the graphene electrothermal film is tightly attached to the bottom end face of the upper metal plate; and the bottom end face of the graphene electrothermal film is tightly attached to the upper end face of the reflective film. According to the invention, the graphene electrothermal film, the reflective film and the metal plate can be produced into the graphene electric heating metal composite plate at one time by utilizing an on-line foaming continuous production process technology, the previous application of the graphene electrothermal film is changed, the production and processing process is simplified to energy conservation, and the use cost is saved.

Description

Technical field: [0001] The invention relates to the technical field of composite materials, and mainly relates to a graphene electrothermal metal composite plate. Background technique: [0002] Graphene is currently the thinnest two-dimensional carbon material that can conduct electricity and heat. In the process of electrification, carbon molecules generate phonons, ions and electrons in the resistance, and the generated carbon molecular groups rub and collide with each other. (also known as Brownian motion) to generate heat energy, and the heat energy is evenly radiated in a planar manner by controlling the far-infrared rays with a wavelength of 5-14 microns. Through the application of the electrothermal function of graphene materials, the performance of traditional products has been greatly improved, thereby renewing. Establish high technical barriers to the industry and promote industrial upgrading. [0003] At present, although the electrothermal function of graphene ...

Problems solved by technology

[0003] At present, although the electrothermal function of graphene is widely used in the market, they are all constructed step by step in the process. There are still some disadvantages in the field of graphene electrothermal film, such as the inability to continuously produce graphene electrothermal products at one time, resulting in The cost is high; some constructions are more difficult to apply in an inverted site; another example is that graphene electric heating products cannot be continuously produced, and there are many construction links in the installation process, the process is complicated, and there are many connection points of graphene electric heating film. The relatively high cost of manpower input and maintenance in the application field needs to be improved
