Low-temperature composite electric heating material and preparation method thereof

The invention relates to a low-temperature composite electric heating material, which consists of two layers of polyethylene terephthalate resin, two layers of epoxy resin glass fiber cloths and a layer of carbon fiber conductive paper, wherein the two layers of epoxy resin glass fiber cloths respectively cover the two sides of the layer of carbon fiber conductive paper, and the two layers of polyethylene terephthalate resin respectively cover the two sides of the two layers of epoxy resin glass fiber cloths. When the low-temperature composite electric heating material is used for building heating, not only can the advantages of a carbon fiber conductive paper, but also the defects of the prior art can be overcome. Therefore, the low-temperature composite electric heating material is an electric heating material which can greatly improve the electric heating conversion efficiency, the heat resistance, the fire resistance, the stability and the service life of heating elements.
