Description

technical field

[0001] The invention relates to an electric heating plate and a preparation method thereof, in particular to a graphene high temperature resistant mica electric heating plate and a preparation method thereof. Background technique

[0002] At present, the main materials of electric heating plates used in the market are carbon matrix epoxy resin insulator material electric heating plates and PET electric heating films. 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. With the increase of market demand for electric heating plates, the requirement for high temperature resistance of electric heating plates is also getting higher and higher, and the electric heating plates of the prior art...
