Description

technical field [0001] The invention relates to the technical field of heating plates, in particular to a non-metallic far-infrared heating plate and a preparation method thereof. Background technique [0002] The heating plate is a safe and reliable electric heating plate with a round or square shape that generates heat without electricity and no open flame after being energized. Because it mainly relies on heat conduction during use, the thermal efficiency is high. However, the current market is all metal heating plates, which have low heat energy conversion and high energy consumption. [0003] In the patent application with the patent application number CN201810692886.9, a method for preparing a high-temperature oxidation-resistant heating plate is disclosed, which belongs to the technical field of heating plate preparation. It is divided into two parts: the base material of the heating element and the heat insulating layer of aluminum metal. By using graphite as the d...
