Temperature-controllable electronic cigarette heating sheet and preparation method thereof

The invention relates to the technical field of ceramic baking heating equipment, in particular to a temperature-controllable electronic cigarette heating sheet and a preparation method thereof. By optimizing the structure of the heating sheet and improving the preparation process, the expansion coefficient difference between the ceramic sheet and the heating body is solved, the sealing difficulty of the surface of the heating body is reduced, the selectable range of the ceramic sheet and the heating body material is expanded, the input voltage is adjusted through the temperature, the heating temperature is controlled, and the use comfort is improved; afterwards, the soldering paste is further improved, the dispersity of the metal powder in the soldering paste is enhanced, no residue exists, the uniformity of a metal heating body circuit is effectively improved, and therefore the heating performance of a heating product is guaranteed. 本发明涉及陶瓷烘烤发热设备技术领域，具体为一种可控温的电子烟加热片及其制备方法；本发明通过对发热片结构优化与制备工艺改进，解决了瓷片与发热体的膨胀系数
