采用钛酸酯偶联剂表面改性水滑石,以活化指数为评价手段,研究偶联剂的用量,温度,时间等因素对改性效果的影响,并采用XRD、FTIR表征改性水滑石的结构,结果表明,钛酸酯能够有效改性水滑石。
The titanate coupling agent was used to modify the hydrotalcite. The activation index was used as evaluation method to study the effect of coupling agent dosage, temperature and time on the modification. The XRD and FTIR were used to characterize the hydrotalcite The results show that titanate can effectively modify hydrotalcite.
