摘要：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（Xm）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Xm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Xm=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。
Nylon 6/66 and nylon 6/66/510 （containing 5%-20%（mol） nylon-510） were synthesized via a hot melting method. The effects of mole fraction of nylon-510 （Xm） on the thermal and mechanical properties of nylon 6/66/510 were systematically studied. The results demonstrate that： （1） when Xm increases, the melting point of the copolyamides decreases from 167.3 ℃ to 126.9℃, and their glass transition temperatures decrease from 46.7℃ to 24.3 ℃; （2） the tensile strength of nylon 6/66/510 remains almost unchanged and is almost equal to that of nylon 6/66; the elongation at break of nylon 6/66/510 is significantly higher than that of nylon 6/66. The adhesion of nylon 6/66/510 onto aluminum sheet with low-surface-energy coating was studied, and the results show that the peeling strength of nylon 6/66/510 reaches a maximum value when Xm = 15% （mol）, which indicates that nylon 6/66/510 is more suitable for adhesion of metal plates with low-surface-energy coatings.
