| 摘 要： | 热熔法制备了一系列聚苯基甲氧基硅氧烷(PPMS)、聚甲基苯基甲氧基硅氧烷(PMPS)改性环氧树脂,通过环氧值、红外光谱(IR)分析表明聚硅氧烷接枝了E-20环氧树脂且环氧基保持不变.探讨了有机硅含量对改性树脂固化体系耐热性能及韧性的影响.实验表明,当E-20环氧树脂与PPMS、PMPS的质量比为7∶3时,改性树脂固化体系的耐热性能明显提高,玻璃化转变温度(Tg)为95.8、88.3℃,分别比改性前提高了9.0℃和1.5℃;质量损失50%时的热分解温度(Td)为476.5、487.8℃,分别比改性前提高了58.3℃和69.5℃.与ED-30固化体系相比,EPMS-30固化物的耐热性能,韧性等力学性能提高的更加明显,并且还具有优良的涂膜性能.

| Abstract: | Silicone modified epoxy resins were prepared by polycondensation of polyphenylmethoxysilicone(PPMS) and polymethylphenylsilicone(PMPS) with E-20 epoxy resin.Oxirane ring and epoxy values were determined by Fourier transform infrared(FTIR) spectroscopy and HCl/acetone method.The data indicated that silicone oligomers were incorporated into epoxy resin with a random polycondensation and without involving the opening of the oxirane ring in the silicone modified epoxy structure.The influences of silicone conten... |
