摘要
The present invention relates to a method for preparing a graphene-containing inorganic coating composition for coating non-ferrous metal objects and a graphene-containing inorganic coating composition prepared thereby, in which the inorganic coating composition contains liquid silica sol that emits far-infrared rays and powdery graphene that has very excellent thermal conductivity, and thus it emits far-infrared rays beneficial to the human body while having excellent durability and thermal conductivity. The method comprises: adding isopropyl alcohol as a solvent to liquid silica sol and a liquid sealant, followed by uniform stirring for 2-3 hours, thereby preparing a first liquid binder; adding powdery graphene, filler and pigment to the first liquid binder, followed by stirring for 8-10 hours, thereby preparing a second binder; and adding a predetermined amount of an adhesion-enhancing agent to the second binder, followed by aging at a temperature of 25 to 32° C. for 9 to 11 hours.
