[0019] Example 1
[0020] Selection: Select zirconium sulfate as the zirconium source, the mixed solution of water and isopropanol (mass ratio 1:3) as the solvent, and the mixture of triethanolamine, sodium gluconate and xylitol as the ligand.
[0021] Weighing: Weigh 8g zirconium sulfate, 15g water, 45g isopropanol, 1g triethanolamine, 3g sodium gluconate, 3g xylitol.
[0022] Reaction: Add zirconium sulfate to a mixed solvent of water and isopropanol, stir until fully dissolved, adjust the pH to 2, then add it to a three-necked flask equipped with a reflux condenser, heat up to 50°C, and stir to react for 2 hours. Add triethanolamine, sodium gluconate and xylitol, continue to stir and react for 2 hours.
[0023] Neutralization: neutralize the reaction product to pH=4
[0024] Dilution: Add low molecular weight polyacrylic acid and sodium polyacrylate mixture to dilute.
