Abstract
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.
Claims5
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 (P2O5),
- 17 to 29.5 wt % of aluminum oxide (Al2O3),
- 0.5 to 3 wt % zirconium dioxide (ZrO2),
- 10 to 30 wt % of sodium oxide (Na2O) and potassium oxide (K2O),
- 10 to 25 wt % of boron trioxide (B2O3), and
- 10 to 15 wt % of zinc oxide (ZnO),
- wherein the coating material is prepared by a process including (i) melting each of the P2O5, the Al2O3, the ZrO2, the Na2O, the K2O, the B2O3, 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.
