| 摘 要： | 研究了聚丙撑碳酸酯（ＰＰＣ）对环氧树脂（ＥＰ）的改性作用、加入２０～３０Ｐｈｒ的ＰＰＣ，环氧树脂力学性能可以大幅度提高，粘接剪切强度为１２３３ＭＰａ，冲击强度为１６．７８ｋＪ／ｍ２；而纯环氧树脂固化物，其剪切强度为９．３６ＭＰａ，冲击强度为９．９９ｋＪ／ｍ２。ＳＥＭ和ＤＳＣ观测表明ＰＰＣ／ＥＰ体系呈两相结构。

| Abstract: | We discussed the epoxy resin modified by adding 20 to 30 phr of polypropylenecarbonate (PPC),the mechanical properties of toughened epoxy resin would be enhanced greatly,e.g;lap shear strength and impact sire.ngth are 12.33 MPa,16.78kJ/ m2, respectively,compared with 9.36 MPa, 9.99kJ / m2 for a resinwithout PPC. Two-phase structure of toughened epoxy resin was observed by SEMand DSC. |
