| 摘 要： | 通过自制的酚醛-纳米蒙脱土(PF-MMT)和γ-氨丙基三乙氧基硅烷-纳米埃洛石(KH550-HNTs)以不同质量配比复配改性PA6, 研究了不同复配比例对PA6结晶性能、热稳定性、吸水性和力学性能的影响。结果表明: PF-MMT复配KH550-HNTs改性PA6提高了体系的热稳定性和抗吸水性, Tg变化不大, 但结晶度下降。纳米PF-MMT复配KH550-HNTs/PA6复合材料的刚性得到提高, 韧性有所下降, 尤其是弯曲强度得到较大提高。

| Abstract: | PA6 was modified by self-made modifier of phenolic-montmorillonite (PF-MMT) and γ-aminpropyltriethoxysilane-halloysite (KH550-HNTs). The effects of different compound proportion on PA6 crystallization, thermal stability, water absorption and mechanical properties were studied. The results show that PA6 matrix composite system, modified by PF-MMT compound KH550-HNTs, whose thermal stability and resistance of water absorption are improved, and Tg is changed little, while the crystallinity of PF-MMT compound KH550-HNTs/PA6 is decreased. The rigidity of the system is enhanced, while toughness decreased a little. The bending strength has a considerable improvement, compared to pure PA6. |
