摘要
通过熔融共混法制备了有机化蒙脱石填充的尼龙 6 6复合材料 ,通过示差扫描量热分析 (DSC)、偏光显微镜照片 (POM )和动态力学分析 (DMA)等手段研究了复合材料的非等温结晶过程、结晶形态和球晶尺寸、动态力学行为等 ,并与普通尼龙 6 6进行了比较 ,发现经过有机化蒙脱石填充的尼龙 6 6的结晶速率比较快 ,球晶尺寸较小 。
In this paper, nylon66/montmorillonite composites with different contents of layered silicate were prepared with melt blending method. The non thermal crystallization, crystal size and thermal mechanical properties of nylon66/montmorillonite composites were studied by differential scanning calorimetry (DSC), polarized optical microscopy (POM) and dynamic mechanical analysis(DMA). In comparison with pure nylon66 the crystallization rate of composites is increased, the size of crystal is decreased and the modulus is also improved.
