本发明公开了一种水相纳米氧化锆颗粒分散体的制备方法，该制备方法采用碱性过氧化氢处理法，即在强碱性锆盐溶液中加入双氧水反应，之后用酸和水分别洗涤沉淀得到产物，这种方法能够使产生过氧离子，使纳米材料表面形成丰富的羟基基团，从而使氧化锆在水中的分散度大大增加，很大程度上解决了纳米氧化锆颗粒分散体制备成本高、易污染环境、难以实现工业化大规模制备的问题，而且无需任何复杂昂贵的表面改性剂，利用此方法制备出的纳米氧化锆颗粒分散体能够很好地适应各种用途，极大的拓宽了氧化锆的应用。

The invention discloses a preparation method of an aqueous nano-zirconia particle dispersion. The preparation method adopts an alkaline hydrogen peroxide treatment method, that is, adding hydrogen peroxide to a strong alkaline zirconium salt solution to react, and then washing with acid and water separately The product is obtained by precipitation. This method can generate peroxide ions and form abundant hydroxyl groups on the surface of nanomaterials, thereby greatly increasing the dispersion of zirconia in water, which largely solves the problem of preparing nano zirconia particle dispersions. High cost, easy to pollute the environment, difficult to achieve industrial large-scale preparation, and without any complex and expensive surface modifiers, the nano-zirconia particle dispersion prepared by this method can be well adapted to various uses, greatly The broadening of the application of zirconia.
