| 摘 要： | 研究了原位聚合ＰＮＭ对环氧树脂和粒子填充环氧树脂的改性作用，加入５％左右的ＰＮＭ，环氧树脂力学性能可以大幅度提高，拉伸强度从纯环氧树脂的５０．９１ＭＰａ、粒子填充（３０ｐｈｒ）环氧树脂的６９．２１ＭＰａ，分别提高到９４．２５ＭＰａ和９１．８５ＭＰａ；断裂韧性从纯环氧树脂的０．８３ＭＰａｍ１／２、粒子填充环氧树脂的０．７２ＭＰａｍ１／２，分别提高到１．８６ＭＰａｍ１／２和１．９８ＭＰａｍ１／２；而其它性能也有不同程度的改善。

| Abstract: | The epoxy resin and particle filled epoxy resin modified by in situ polymerized polyazomethine(PNM) have been discussed. The mechanical properties of modified epoxy resins can be enhanced greatly when the content of PNM is about 5 phr. For example, the tensile strength is enhanced to 94.25 PMa and 91.85 MPa for epoxy resin and particle filled (30 phr) epoxy resin with PNM, respectively, while those without PNM are 50.91 MPa and 69.21 MPa, correspondingly, the crack toughness is enhanced to 1.86 MPam 1/2 and 1.98 MPam 1/2 for those with PNM as compared with 0.83 MPam 1/2 and 0.72 MPam 1/2 for those without PNM, respectively, other properties are enhanced to varying degrees too. |
