摘要
利用超声波分散方法将凹凸棒土分散在水中 ,采用硅烷偶联剂KH 5 70对凹凸棒土纳米棒晶进行表面处理 ,将经表面处理的凹凸棒土与聚丙烯复合制成纳米复合材料 ;研究了纳米复合材料的结晶行为与力学性能。结果表明 :超声波有利于凹凸棒土的分散 ;凹凸棒土质量分数较低时 。
Attapulgite was dispersed in water by stirring and ultrasonic vibration, and then treated with silane coupling agent KH570 The treated attapulgite was blended with polypropylene (PP) via melt compounding to prepare PP/attapulgite nano composites The crystalline behavior and mechanical properties of the prepared nano composite were studied The results showed the use of ultrasonic vibration was favorable to the dispersion of attapulgite; when the mass fraction of attapulgite in the composite was low, the mechanical properties of the composite were improved to a certain extent
