摘要(Abstract)：

通过熔融共聚法合成了尼龙6/66和尼龙6/66/510热熔胶，在尼龙510含量（X_m）为0%~20%（mol），考察了尼龙6/66/510的热性质和力学性的变化规律。结果表明：（1）随着X_m的增大，尼龙6/66/510的熔点从167.3℃下降至126.9℃，玻璃化转变温度从46.7℃下降至24.3℃；（2）尼龙6/66/510的拉伸强度基本上保持恒定，且与尼龙6/66几乎相等，而其断裂伸长率较尼龙6/66有明显提高。运用低表面能涂层铝板对该热熔胶进行了剥离强度实验，结果发现，当X_m=15%（mol）时，尼龙6/66/510热熔胶的剥离强度达到最大值，表明尼龙510含量为15%（mol）的尼龙6/66/510热熔胶更适用于低表面能涂层金属板的黏结。
