NOVELTY - A self-controlling temperature heating sheet comprises a carrier and conductive filler. The carrier is a polymer material, and the conductive filler is at least one of metal particles and inorganic non-metal conductive fillers. USE - Self-controlling temperature heating film. ADVANTAGE - The heating film has high thermal efficiency, fast heating speed, and safety, is energy-saving, and enables timely and accurate temperature control. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the self-controlling temperature heating film, which involves smelting the carrier to obtain a product (I), adding conductive filler to the product (I), and performing mixing and banburying to obtain a mixed product, extruding and calendering the mixed product to form a self-controlling temperature film, and then designing an open loop circuit on the self-controlling temperature film.
