▎ 摘　　要

NOVELTY - The board has a graphene electric heating filler layer (B) that is coated on a substrate (A). An insulating sealing layer (C) is provided to seal the graphene electric heating filler. A grid-shaped metal thermal conductive layer is fixedly installed on the insulating sealing layer. A floor (F) is mounted on the metal thermal conductive layer in a detachable manner. Honeycomb aluminum (D) is filled in the metal thermal conductive layer (E). An electrode is electrically connected with the graphene electric heating filler. The substrate is formed of foaming ceramic with excellent insulating property. USE - Graphene layered composite floor heating board. ADVANTAGE - The need to use insulating and chemically unstable polymer compounds as auxiliary substrates is avoided, and better heating effect and service life of the floor heating board are ensured. The graphene filler is fixed by direct coating, so as to have stronger operability and set into different circuit structures according to requirements and the application scenarios of graphene filler. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene layered composite floor heating board.
