Abstract
Official abstract text for this publication.
A coating composition, coating glass and a method for preparation thereof, and a cooking appliance including the coating class are described. The coating composition includes a coating material and a heat conductive oxide nano powder that is 5 to 10 wt % with respect to a weight of the coating material. The coating composition provides an excellent infrared reflective function, a high transmittance, and an excellent cleaning performance.
First claim
Opening claim text (preview).
What is claimed is: 1. A coating composition, comprising: a coating material and a heat conductive oxide nano powder that is 5 to 10 wt % with respect to a weight of the coating material, wherein the coating material comprises: 20 to 40 wt % of phosphorus pentoxide (P 2 O 5 ), 17 to 29.5 wt % of aluminum oxide (Al 2 O 3 ), 0.5 to 3 wt % zirconium dioxide (ZrO 2 ), 10 to 30 wt % of sodium oxide (Na 2 O) and potassium oxide (K 2 O), 10 to 25 wt % of boron trioxide (B 2 O 3 ), and 10 to 15 wt % of zinc oxide (ZnO), wherein the coating material is prepared by a process including (i) melting each of the P 2 O 5 , the Al 2 O 3 , the ZrO 2 , the Na 2 O, the K 2 O, the B 2 O 3 , and the ZnO, (ii) quenching the melted coating material components, and (iii) grinding the quenched coating material components, wherein the heat conductive oxide nano powder is prepared separately from the coating material, and wherein the coating composition is a mixture of the coating material and the heat conductive oxide nano powder. 2. The coating composition of claim 1 , wherein the coating material further comprises 5 or less wt % of at least one of lithium oxide (Li 2 O), barium oxide (BaO), or calcium oxide (CaO). 3. The coating composition of claim 1 , wherein the coating material includes 10 to 20 wt % of Na 2 O, and 5 to 10 wt % of K 2 O. 4. The coating composition of claim 1 , wherein the heat conductive oxide nano powder includes at least one of indium tin oxide (ITO), tin oxide (SnO x ), titanium oxide (TiO x ) and zinc oxide (ZnO x ). 5. The coating composition of claim 1 , wherein a calcination temperature of the coating composition is less than or equal to 700° C.
