摘　　要：采用傅立叶变换红外光谱(FTIR)仪、热重分析仪和X射线衍射仪等手段研究了超声波振动与磁力加热搅拌两种不同方式制备的有机改性蒙脱土(OMMT),通过设计正交实验验证了改性剂的用量、pH值、超声波振动时间和超声波振动功率4个因素对OMMT的层间距的影响,同时,还验证了不同种类的OMMT对聚丙烯(PP)雾化性能的影响。结果表明,相比磁力加热搅拌法,超声波振动制备的OMMT不需加热和搅拌、反应速度快、制备的OMMT层间距更大;通过正交实验得出的最佳方案为选用十六烷基三甲基溴化铵的用量为1.5 g,pH值为7.0或6.5、超声波振动60 min,超声波功率为80%;按照最佳方案采用超声波技术制备的OMMT,对于改善PP的雾化有较好的效果。The organophilic-modified montmorillonite(OMMT)prepared by ultrasonic vibration and magnetic stirring was studied by FTIR,TGA and XRD.The influence of modifier dosage,pH value,ultrasonic vibration time and ultrasonic vibration power on OMMT layer spacing was verified by orthogonal experiment.In addition,the influence of different kinds of montmorillonite on the atomization performance of polypropylene(PP)was also investigated.The results show that OMMT prepared by ultrasonic vibration does not need heating and stirring,the reaction speed is faster,and the OMMT layer spacing is larger than the OMMT compared with magnetic heating and stirring method;the optimal scheme obtained by orthogonal experiment is that the dosage of CTAB is 1.5 g,the pH value is 7.0 or 6.5,the ultrasonic vibration is 60 min,and the ultrasonic power is 80%.According to the optimal scheme,the OMMT prepared by ultrasonic technology has a good effect on improving the atomization of PP.
