The present invention provides a conductive heat-dissipating graphene coating material comprising (A) graphene oxide sol, (B) composite ceramic made up of alumina, titania and zirconia, (C) colloidal silica, (D) deflocculant, and (E) a silane coupling agent. The conductive heat-dissipating graphene coating material according to the present invention shows electrical conductivity and, in particular, shows excellent thermal conductivity as well as overall excellent mechanical and chemical properties such as heat resistance to high temperatures, pencil hardness, high resistance to corrosion, hydrophile properties, and anti-fouling properties. Thus, the conductive heat-dissipating graphene coating material according to the present invention can be variously applied to the field of various liquid crystal display devices such as an LED, a next-generation electronic material package, a TV, a computer monitor, and a mobile phone; a mobile device such as a mobile phone, a laptop, and a tablet PC; parts of household items such as a gas stove, a heater, a fan, a refrigerator, and an iron; and various industrial supplies such as a building, a building material, a vehicle, and a ship. Further, the conductive heat-dissipating graphene coating material can be coated on almost any material such as metal, nonmetal, a plastic polymer material, FRP, fabric, textile, leather, film, glass, concrete, and wood, can be applied to various materials such as a high-temperature surface heating body, a heating film, a heating blanket, a heating board (tile, marble, etc.), an antifreeze pipe, and a heating pipe for heating by having high electrical conductivity and, in particular, can absorb microwaves to be easily heated up to 1000°C in a moment, thereby being applied to materials such as a dryer, a heater, and an evaporation chamber. |
