聚酰胺弹性体对生物基聚酰胺56和聚酰胺66共混物的增韧改性及其发泡行为研究OA北大核心CSTPCD
Study on toughening modification and foaming behavior of biobased polyamide 56/polyamide 66 blends by polyamide elastomer
采用聚酰胺弹性体MH2030对生物基聚酰胺56/聚酰胺66(PA56/PA66)混合物进行增韧改性,并采用超临界CO2间歇发泡技术制备了一系列不同的生物基PA56泡沫.研究了MH2030含量对PA56/PA66结晶性能、流变性能、力学性能及发泡性能的影响.结果表明,MH2030的加入提高了PA56/PA66材料的黏弹性和发泡性能,使结晶峰向高温方向移动,可能作为了体系的成核剂促进了结晶.MH2030使PA56/PA66材料的韧性增加、刚性降低,在…查看全部>>
Biobased polyamide 56(PA56)/polyamide 66(PA66)blends were toughened by using polyamide elastomer(MH2030),and then a series of bio-based polyamide blend foams were prepared through a supercritical CO2 intermittent foaming technology.The effect of MH2030 content on the crystallization,rheological,mechanical properties,and foam-ing behaviors of the PA56/PA66/MH2030 blends was investigated.The results indicated that the introduction of MH2030 improved the viscoe…查看全部>>
