Heat-not-burn electronic cigarette ceramic heating sheet and preparation method thereof

The invention discloses a heat-not-burn electronic cigarette ceramic heating sheet and a preparation method thereof. The heat-not-burn electronic cigarette ceramic heating sheet comprises a ceramic bottom sheet, resistance paste, protective glaze and a metal electrode. Through innovative process matching, the combination principle of a heating layer and ceramic is changed, multiple times of silk-screen printing and tunnel furnace sintering are avoided, and the technological process is simplified; meanwhile, precious metals such as palladium, ruthenium, platinum and gold and a conventional glass powder binding phase are not used in the resistance layer, so that the production cost is greatly reduced; metal nickel, copper, gold and the like with excellent conductivity can be plated to designated positions to serve as electrodes; according to the method, the resistance layer can be directly and tightly combined on the ceramic substrate through the active metal brazing technology, the design thought that oxidatio
