Embodiment 1
[0010] Step (1). Put zinc acetate and oleic acid in a container at a molar ratio of 0.05:1, heat at 50°C for 10 minutes to obtain a uniform transparent solution; then reflux at 120°C for 40 minutes; then heat at 60°C The lower heat preservation spare;
[0011] Step (2). Put the glass sheet into the acetone solution and clean it with ultrasonic vibration for 30 minutes; then heat the cleaned glass sheet to 40°C; apply the solution obtained in step (1) to the heated After the surface of the glass sheet;
[0012] Step (3). Dry the glass sheet coated with the solution at 150° C. for 3 hours; then heat-treat at 400° C. for 6 hours, and then cool naturally to obtain a zinc oxide coating.
Embodiment 2
[0014] Step (1). Put zinc acetate and oleic acid in a container at a molar ratio of 0.2:1, heat at 80°C for 3 minutes to obtain a uniform transparent solution; then reflux at 150°C for 30 minutes; The lower heat preservation spare;
[0015] Step (2). Put the glass sheet into the acetone solution and clean it with ultrasonic vibration for 20 minutes; then heat the cleaned glass sheet to 60°C; use the screen printing method to apply the solution obtained in step (1) to the heated After the surface of the glass sheet;
[0016] Step (3). Dry the glass sheet coated with the solution at 250° C. for 1 hour; then heat-treat at 450° C. for 3 hours, and then cool naturally to obtain a zinc oxide coating.
Embodiment 3
[0018] Step (1). Put zinc acetate and oleic acid in a container at a molar ratio of 0.1:1, heat at 60°C for 5 minutes to obtain a uniform transparent solution; then reflux at 140°C for 35 minutes; then heat at 70°C The lower heat preservation spare;
[0019] Step (2). Put the glass sheet into the acetone solution and clean it with ultrasonic vibration for 25 minutes; then heat the cleaned glass sheet to 50°C; apply the solution obtained in step (1) to the heated After the surface of the glass sheet;
[0020] Step (3). Dry the glass sheet coated with the solution at 200° C. for 2 hours; then heat-treat at 420° C. for 4 hours, and then cool naturally to obtain a zinc oxide coating.
