摘要
通过熔融共混的方法制备了组成不同的PA1212/POE/POE-g-MAH三元共混合金材料,并对共混材料的力学性能和流变特性进行测定与分析。结果表明,三元共混合金材料在所研究的测试范围内出现明显的凝胶点,对应于凝胶点组成(PA1212/POE/POE-g-MAH的质量比为80/13/7)的共混材料韧性最好,缺口冲击强度达到84.79 kJ/m~2,是纯尼龙1212的5.2倍。这表明共混材料的力学性能与流变特性具有一定的相关性,流变学是确定尼龙1212超韧材料配方的一种简单、快速、有效的实验方法。
We had prepared PA1212/POE/POE-g-MAH blends by reactive blending and investigated their mechanical properties and rheological behavior.The rheological curves of blends shows an obvious "gel point",the blend(80/13/7) corresponding to the gel point has higher notched izod impact strength than those of other blends.The results indicated the "gel points" acquired from the dynamic rheological data and the "super-toughness points" of the blends have a corresponding relationship.Thus,just by simple composition designs and a small amount of samples,the super-toughness point could be conveniently determined by the dynamic rheological measurements.
