The present invention relates to enameled-heated cooking utensils with a non-stick
ceramic coating layer, and a preparation method thereof, wherein enamel
layers are formed on both sides of a main body of heating cooking utensils which is made by using an iron and steel material such as cast
ion, steel, cold rolled steel plate and the like, and a non-stick
ceramic coating layer which emits anions, radiates
far infrared rays, is nonadhesive and does not harm the
human body, is formed on the outer surface of the enamel
layers. The
surface roughness of the enamel
layers is improved by sandblasting the outer surface of the enamel layers or forming an enamel layer containing silica fine particles on the outer surface of the enamel layers after forming the enamel layers on the outer portion of the main body made of an iron and steel material, and the
adhesive force between the enamel layers and the non-stick
ceramic coating layer is enhanced by forming a non-stick
ceramic coating layer on the outer surface. The enameled heating cooking utensils according to the present invention has excellent
corrosion resistance, abrasion resistance,
heat resistance and the like, prevents food from sticking when heating food, and is environmentally-friendly by forming a
ceramic coating layer which does not harm
human body differently from
polytetrafluoroethylene (PTFE) recently used as a non-stick coating agent, as a non-stick layer, and thus the demand of the enameled-heated cooking utensils according to the present invention is expected to remarkably increase hereafter.
