Abstract

The invention discloses a rare earth nano high-transparency glass insulating coating which comprises the following components in percentage by weight: 70-90 percent of hydroxy acrylic modified fluorocarbon emulsion, 5-15 percent of nano indium tin oxide (ITO) slurry, 5-15 percent of purified water, 0.05-0.2 percent of cerium oxide, 0.1-0.8 percent of dispersing agent and 0.1-0.8 percent of coalescing agent. A preparation method of the rare earth nano high-transparency glass insulating coating comprises the steps: firstly, adding the hydroxy acrylic modified fluorocarbon emulsion, then adding the dispersing agent and the coalescing agent, then adding the purified water, dispersing at a high speed of 800 turns per minute for 10-20min, respectively adding the nano indium tin oxide slurry and cerium oxide, and fully stirring and dispersing at a speed of 800 turns per minute for 10-20min. The rare earth nano high-transparency glass insulating coating is high in transparency.
