摘要
本文以铝酸酯为改性剂对电气石的表面改性反应进行了探讨,结果表明,以苯为溶剂,铝酸酯的用量为电气石的1.5%,70℃下搅拌0.5h,可使改性电气石的活化指数达到97%;所得铝酸酯改性电气石表面具有较强的疏水特性,而没有影响其晶体结构。
The surface modification of the tourmaline powder with an aluminic ester was discussed.The experimental results showed that the activation index of aluminic ester modified tourmaline powder reached to 97% when 1.5% aluminic ester reacted with tourmaline powder at 70℃ for 0.5 h in benzene;and the aluminic ester modified tourmaline had an excellent hydrophobic property,but with no change in crystal configuration of tourmaline.
