NOVELTY - A structure comprises an insulating heat-conducting functional layer (2), a heating functional layer (3), and an insulating heat insulation functional layer (4) arranged on a substrate (1) from bottom to top by spraying technology. The heating functional layer comprises 2-10 %mass graphene, and 90-98 %mass nickel-chromium alloy. The insulating heat-conducting functional layer comprises 1-3 %mass nickel-chromium-boron-silicon alloy, 88-96 %mass zirconium dioxide, 2-8 %mass resin, and 1-3 %mass curing agent. The heat insulation functional layer comprises 3-6 %mass nickel-chromium-boron-silicon alloy, 2-16 %mass sealing agent, and 80-95 %mass aluminum nitride. USE - The structure is useful for realizing substrate heating function. ADVANTAGE - The structure: solves the problems of poor heating effect, complicated process and large weight and volume in the current traditional electric heating method by using spraying technology to realize the integrated integration of heating function and temperature feedback function on the heated portion; is simple; realizes efficient and low energy consumption of the substrate heating effect; has excellent heat directional transmission, and environmental performance, low cost, and high thermal conductivity; and can make each functional layer more uniform and compact, so that the functional layer can be more uniformly and compactly coated on the substrate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the structure for realizing substrate heating function. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the functional coating.
