| 摘 要： | 以间苯二酚二缩水甘油醚(RDGE)和1,1,1-三(对羟基苯基)乙烷为原料,合成了三官能团环氧树脂TEP,并分别与异佛尔酮二胺(IPDA)单一体系和IPDA/2-乙基-4-甲基咪唑(2E4MZ)复合体系进行常温固化。通过DSC、热重分析(TGA)、动态机械热分析仪、耐化学介质以及力学性能测试对比研究了TEP树脂与两种固化体系的固化反应动力学、固化度以及热稳定性。结果表明:复合固化体系较单一固化体系初始表观活化能更低,复合体系固化物的固化程度、玻璃化转变温度、耐腐蚀性均优于单一IPDA固化体系。 |

| Abstract: | The trifunctional epoxy resin(TEP) was synthesized by resorcinol diglycidyl ether and 1, 1, 1-tris-p-hydroxypheny lethane, and cured with isophorone diamine(IPDA) and IPDA/2-ethyl-4-methylimidazole(2E4MZ) at room temperature. Curing reaction kinetics, curing degree, thermal stability were comparatively researched by differential scanning calorimetry(DSC), thermogravimetric analysis(TGA), dynamic mechanical thermal analysis(DMA), tests of chemical resistance and tests of mechanical properties. The results show that the composite curing system has lower apparent activation energy, and the curing degree, glass transition temperature(Tg) and corrosion resistance are better than IPDA curing system. |
