【摘要】 通过 DSC方法研究了蒙脱土对尼龙 66熔融与结晶行为的影响 ,探讨了蒙脱土对尼龙 66结晶的成核作用。发现有机蒙脱土使尼龙 66的熔融峰温度 Tm 提高 5 .3℃ ,使结晶峰温度提高 1 3～ 2 4℃ ;二次熔融多产生双重熔融峰 ,蒙脱土的加入有利于生成低温峰。更多还原

【Abstract】 The influence of montmorillonite(Mont.) on melting and crystallization behavior of nylon 66 has been investigated by DSC. The results show that the melting and crystallization temperature of nylon 66 were increased by 0 5 ℃ and 13~24 ℃ respectively after adding 4 76%(by mass) of organophilic montmorillonite. The occurance of two melting peaks of PA66 and composites may be resulted from the differences of the crystal types. Addition of montmorillonite favored the production of 2 peeks in the second melting process.更多还原
