▎ 摘  要

NOVELTY - Exothermic composition comprises mixed binder obtained by mixing epoxy acrylate or hexamethylene diisocyanate, polyvinyl acetal resin, and phenol-based resin, partially graphitized graphene oxide particles having insulating property within 1-20 layers, conductive particles comprising at least two of carbon nanotube particles, graphite particles and metal powder, organic solvent and dispersing agent. USE - The exothermic composition is useful for heating element (claimed). ADVANTAGE - The exothermic composition induces direct chemical covalent bond, and has stable heat resistance even at temperature of 300 degrees C. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for heating element comprising a ceramic substrate (51), and a heating electrode (57) formed by printing the exothermic composition on upper surface of the ceramic substrate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the heating element. Heating element (50) Ceramic substrate (51) Heating electrode (57)
