摘要
本研究是以相对丰富的低品位天然钠基膨润土为原料,用A-18和A-30为复合有机改性剂,pH值控制在8.5,酸活化时间为90min,最佳反应固液比为1∶15,有机改性反应温度控制在70℃。制备出了粘度达4 150mPa.s、白度为74.5%、d(001)值由12.337A达到了25.514A的较高性能的有机膨润土。
In this study, the relative abundance of low-grade natural sodium bentonite as raw material, A-I 8 and A-30 as complex organic modifier, pH value is control in 8.5, acid activation time is 90 minutes, the best reaction solid-liquid ratio is 1 ： 15, organically modified reaction temperature is 70~C. Prepared the viscosity 4 150mPa·s, whiteness is 74.5%, d （001） value is form 12.337A to 25.514A, which is the higher quality organic bentonite.
