Title:
ENAMELED-HEATED COOKING UTENSILS WITH NON-STICK CERAMIC COATING LAYER, AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/010780
Kind Code:
A1
Abstract:
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.
