摘要
以十四碳烯琥珀酸酐为改性剂对电气石的表面改性进行了探讨,以改性产物对水的解除价以及在液体石蜡中的浊度为指标对十四碳烯琥珀酸酐改性电气石工艺条件进行了优化,并利用IR,XRD及SEM等分析方法对改性电气石的结构及形貌进行了表征。改性结果表明改性电气石接触角最高可达101.3゜,浊度可达95.3。结构分析表明十四碳烯琥珀酸酐与电气石表面羟基发生了反应,将十四碳烯琥珀酸基团引入到了电气石表面,得到了十四碳烯琥珀酸电气石酯。
The surface modification of tourmaline powder with tetradecenylsuccinic anhydride was studied in this work, and the reaction process conditions were optimized according to the experimental parameters of contact angle and turbidity in liquid paraffin. The structure of the modified tourmaline was characterized by means of IR, XRD and SEM. The results showed that the contact angle of modified tourmaline was up to 101.3 ~ and the turbidity was up to 95.3. The structural analysis indicated that tetradecenylsuccinic group was attached onto the surface of tourmaline by the reaction of tourmaline with tetradecenylsuccinic anhydride to get a polymerizable tourmaline methacrylate. The experimental results indicated that modified tourmaline presented enhanced hydrophobicity than the unmodified tourmaline.
