二次插层有机膨润土的制备方法
摘要：
二次插层有机膨润土的制备方法，其特征在于首先将钠基膨润土进行一次过渡金属离子化，形成一次过渡金属离子插层，然后进行二次有机化，形成二次有机插层。通过阳离子交换引入过渡金属离子，有机大分子以配位键与金属离子结合，从而增大膨润土的片层间距。
摘要（英）：

The invention relates to a preparation method of secondarily intercalated organic bentonite. The invention is characterized in that firstly conduct transition metal ionization for sodium based bentonite for one time to form transition metal ion intercalation; then organise the bentonite for the second time for form a secondary organic intercalation. The transition metal ions are introduced via cation exchange, organic macro molecules are combined with metal ions via coordination bond, which enlarges the space between sheet layers of the bentonite.
