Problems solved by technology

The above electric heating plate has a low temperature resistance coefficient and can only be used below 100°C
And in the process of use, it has the disadvantages of large deformation of the electric heating plate, low fire protection level, large safety hazard, high failure rate, large attenuation power, and fire phenomenon.
As the market demand for electric heating panels increases, the requirements for the high temperature resistance of electric heating panels are also getting higher and higher. Existing electric heating panels that can only be used below 100°C cannot meet the needs of the market.

Embodiment 1

[0033] Such as figure 1 with 2 As shown, a graphene high temperature resistant mica electric heating plate includes a surface decoration layer 1, an upper mica insulating layer 2, a graphene heating layer 3 and a lower mica insulating layer 4 fixedly connected by an adhesive from top to bottom. The surface decoration layer 1 is set as a PET heat transfer film or a UV color printing decoration layer, and the PET heat transfer film is selected in this embodiment. The upper mica insulating layer 2 and the lower mica insulating layer 4 respectively include several layers of mica insulating paper.

[0034] The graphene heating layer 3 includes a graphene conductive paper 31 and a copper tape 32 fixed on the graphene conductive paper 31 and arranged around the graphene conductive paper. The copper tape 32 is fixed on the periphery of the graphene conductive paper 31 by graphene conductive glue. The top and bottom of the graphene heating layer 3 are coated with silicone resin glue...

Embodiment 2

[0049] Graphene high temperature resistant mica electric heating plate and epoxy resin electric heating plate are resistant to temperature and insulation electrical strength characterization data table 1 in embodiment 1 as shown:

[0050] Table 1 Example 1 Graphene high temperature resistant mica electric heating plate and epoxy resin electric heating plate are resistant to temperature and insulation electrical strength characterization data

[0051]

[0052] As shown in Table 1, the deformation of the epoxy carbon crystal electric heating plate is not large when the temperature is within 50°C, but the deformation is already large when the temperature is 100°C, which may cause the internal circuit to be damaged. When the temperature is 200°C, the carbon crystal of the circuit is destroyed and catches fire. Therefore, the epoxy resin carbon crystal electric heating plate is suitable for heating at a temperature of less than 50°C because of its low temperature resistance, whic...
