通过异步合成法,将预聚的聚甲基丙烯酸甲酯(PMMA)用于改性双酚A型氰酸酯树脂(BADCy),制备了改性BAD-Cy.文章通过对材料进行弯曲强度、冲击强度、动态热机械分析(DMA)、SEM、FTIR分析,探讨不同PMMA添加量对改性BADCy力学性能的影响.结果显示,与纯BADCy相比,当PMMA的质量分数为20%时,改性BADCy弯曲强度和冲击强度分别提高58.5%和88%,环氧树脂(EP)与BADCy相分离消失,玻璃化温度(Tg)基本保持不变,同时改性BADCy的粘性较低,有助于固化浇铸成型.通过使用TGA、DSC等测试手段探讨不同PMMA添加量对材料热性能的影响.结果表明,当PMMA质量分数为20%时,改性BADCy的热失重温度、质量保持率基本不变,固化热降低,反应可控性增强.
