Ceramic heating sheet and preparation method thereof

The invention discloses a ceramic heating sheet and a preparation method thereof, relates to the field of ceramic heating sheets, and aims to solve the problems of low heat conductivity and non-uniform heat conduction of the existing heating sheet. The technical scheme is characterized in that the ceramic heating sheet comprises a ceramic sheet and a metallization layer arranged on the surface of the ceramic sheet through magnetron sputtering; a glass-phase-free metal heating body is printed on the surface of the metallization layer in a silk-screen mode, and the surface of the metal heating body is covered with cleaning glaze. According to the ceramic heating sheet and the preparation method thereof, the ceramic heating sheet with uniform heat conduction and high heat conductivity can be prepared. 本发明公开了一种陶瓷加热片及其制备方法，涉及陶瓷加热片领域，旨在解决目前加热片导热率低，导热不均匀的问题，其技术方案要点是：一种陶瓷发热片，包括陶瓷片以及经磁控溅射在陶瓷片表面的金属化层，金属化层表面丝网印刷有无玻璃相的金属发热体，金属发热体表面覆有清洁釉。本发明的一种陶瓷加热片及其制备方法能够制备导热均匀、热导率高的陶瓷加热片。
