Surface Modification and Structural Characterization of Tourmaline Powder by KH-171
-
摘要:
这是一篇矿物材料领域的论文。以硅烷偶联剂KH-171为改性剂对电气石粉体进行改性，依据改性电气石的接触角和在液体石蜡中的浊度为参数，对改性电气石的工艺条件进行了优化。实验结果表明，在体系pH值为9，改性剂KH-171用量为2 mL，醇水比为1:5的条件下60 ℃反应2 h时，所得改性电气石的接触角达到133o，显示了优良的疏水性能。利用IR、SEM和XRD分析对改性电气石的结构与形貌进行了表征，结果表明，电气石表面成功引入带有碳碳双键的有机官能团，没有影响电气石原有晶体结构，但有效降低了电气石的团聚现象，展示了更好的分散性能。
Abstract:This is an article in the field of mineral materials. The tourmaline powder was modified with silane coupling agent KH-171, and the process conditions were optimized with the parameters of contact angle and turbidity of the modified product in liquid paraffin. The test results showed that the contact angle of the resulting modified tourmaline reached 133 ℃ when reacted at 60 ℃ for 2 h at a system pH value of 9, a dosage of modifier KH-171 of 2 mL, and an alcohol-to-water ratio of 1∶5, showing excellent hydrophobic properties. The modified tourmaline was characterized by IR, SEM and XRD. The results showed that the organic functional groups with carbon-carbon double bonds were successfully connected to the surface of tourmaline without changing the original crystal structure, but the agglomeration of tourmaline reduced effectively and showed better dispersion performance.
