<p>The present invention relates to a printing ink for a ceramic surface, and a printing method for a ceramic surface using same. Particularly, the ceramic surface, consisting of 20-60 wt% of a modified silicone resin, 10-40 wt% of heat resistant pigment, 0.5-10 wt% of alumina powders, 0.5-5 wt% of fumed silica, and 29-45 wt% of a solvent, is printed, thereby enabling the ink to be easily printed on the ceramic surface and also providing good adhesion of a printed film. Also, the present invention relates to a printing method for a ceramic surface using the printing ink for a ceramic surface, characterized in that wettability and adhesion can be improved by converting low surface energy (water contact angle of 70° or higher), of an object on which a heat-resistant ceramic printed film containing organic modified silicone resin paint as a binder is formed, into high surface energy (water contact angle of 30° or lower) through a flame treatment, by using the printing method for a ceramic surface, the printing method comprising: a pretreatment step (S1) of performing a flame treatment by subjecting the object to a 1200°C-2000°C flame for 5-10 seconds; a printing step (S2) of printing the ceramic surface, which has undergone the pretreatment step (S1), by using the printing ink for a ceramic surface; a drying step (S3) of drying the ink printed on the ceramic surface at 20°C-25°C for 5-20 minutes; a hardening step (S4) of hardening the ink printed on the ceramic surface in a hardening furnace at 250°C-320°C for 10-30 minutes; and a cooling step (S5) of cooling at 20°C-25°C the object which has undergone the hardening step (S4).</p> |
