摘　　要：利用聚己二酰间苯二甲胺(MXD6)与聚己二酰己二胺(PA66)复合方法使材料加工性能得显著改善,研究不同配比的MXD6与PA66添加量对复合材料各项性能的影响。研究结果表明:当在复合材料中加入功能性树脂后可使各试样的熔点发生降低,更有助于进行加工成型,同时结晶温度升高,使复合材料更易结晶。当在试样中加入功能性树脂后可使其降解温度明显降低,从而影响了复合材料的热稳定性。该研究有助于提高聚己二酰材料的制备,为后续工艺参数的确定奠定一定的理论基础。The processing properties of polyadipyl-m-benzodimethylamine(MXD6)and polyadipyl-hexamethylenediamine(PA66)were significantly improved by the composite method.The effects of different proportions of MXD6 and PA66 on the properties of the composite were studied.The results show that the melting point of each sample can be reduced when the functional resin is added to the composite,which is more conducive to the processing and molding.At the same time,the crystallization temperature is increased,which makes the composite easier to crystallize.When the functional resin is added to the sample,its degradation temperature can be significantly reduced,which affects the thermal stability of the composite.This study is helpful to improve the preparation of polyadipyl material and lay a theoretical foundation for the advantages of subsequent process parameters.
