Boron-containing polysilicate magnesium zinc sulfate inorganic composite flocculant as well as preparation method and application thereof

The invention belongs to the technical field of flocculants, and particularly relates to a boron-containing polysilicate magnesium sulfate zinc inorganic composite flocculant as well as a preparation method and application thereof. The invention provides a boron-containing polysilicate magnesium sulfate zinc inorganic composite flocculant, which comprises polysilicic acid, and boron, magnesium sulfate and zinc sulfate which are loaded in internal pore channels and on the surface of the polysilicic acid. The metal ions (magnesium ions and zinc ions) and the boron element are added to jointly increase the stability and the polymerization degree of the polysilicate flocculant, the stability effect of the polysilicate flocculant can be greatly improved after boron is added, and the flocculation effect can also be improved. 本发明属于絮凝剂技术领域，具体涉及一种含硼聚硅酸硫酸镁锌无机复合絮凝剂及其制备方法和应用。本发明提供了一种含硼聚硅酸硫酸镁锌无机复合絮凝剂，包括聚硅酸和负载于聚硅酸内部孔道和表面的硼、硫酸镁和硫酸锌。本发明通过加入金属离子(镁离子和锌离子)和硼元素来共同增加聚硅酸盐絮凝剂的稳定性和聚合度，加入硼之后可大大提高其稳定效果，还可增加絮凝效果。
