| 摘 要： | 将环己基硅倍半氧烷硅三醇与环氧树脂E-51在环烷酸钴催化下进行反应,制成硅倍半氧烷-环氧杂化材料.通过傅立叶红外光谱、差热分析证实,反应具有较低的活化能,只是笼型结构外围的Si-OH与环氧基团进行反应,反应对笼型结构无影响;动态力学性能与热稳定性的分析表明,与4,4′-二氨基二苯砜固化的环氧固化物相比,硅倍半氧烷-环氧杂化材料具有较高的玻璃化转变温度、储能模量及热分解温度和热残余量.

| Abstract: | The silsesquioxane-epoxy hybrid resin was prepared from cyclohexyl-trisilanol polyhedral silsesquioxane (c-C_6H_ 11 )_7Si_7O_9(OH)_3 and epoxy resin E-51 in the existing of the cobalt naphthanate as catalyst. Fourier transform infrared (FTIR) and differential scanning calorimetry(DSC) showed that the reaction had lower activation energy Ea, and silanols attaching to Si atoms react with epoxy groups during the cured processing, which had little influence on the cage structure. The dynamic mechanical analysis(DMA) and thermogravimeric analysis(TGA) showed that the cured resin had higher Tg, higher storage modules, decompose temperature(Tdec) and thermal residue, comparing with the cured 4, 4'-(phenylsulfonyl)aniline, comparing with E-51/DDS cured network. |
