摘要
通过熔融挤出制备了PPS/PA6/纳米CaCO3三元复合材料,并通过原子吸收光谱、流变仪、扫描电镜对复合体系进行了表征,研究了纳米CaCO3对PPS/PA6体系形态性能的影响。结果表明,纳米CaCO3主要分布在PPS相中,而在PPS/PA6两相界面处和PA6相中分布较少;纳米CaCO3的加入使PPS黏度上升而使PA6的黏度略有下降,PPS/PA6体系由原来的PA6连续相PPS颗粒相结构变为两相共连续的结构,且在注塑流动方向上PPS呈纤维状取向分布。
Polyphenylene sulfide （PPS）/nylon6/nano-CaCO3 composites were prepared by means of melt blending on a twin-screw extruder followed by injection molding. The composites were characterized by means of atomic absorption spectrometry （AAS）, rheology and scanning electron microscopy （SEM）. The effect of nano-Ca- CO3 on the morphology and property of the composite were studied. The results showed nano-CaCO3 located mainly in PPS phase, but less in the interface of PPS/PA6 and PA6 phase. The addition of nano-CaCO3 made the viscosity of PPS increased and that of PA6 decreased slightly. A typical sea-island structure for PPS/PA6 blends without Nano-CaCO3 was observed. By the addition of nano-CaCO3 the morphology of PPS/PA6 was changed greatly and PPS appeared a fiber like structure along the injection direction.
