| 摘 要： | 针对双氰胺固化环氧树脂时固化温度过高的缺点,从自行设计并合成的一系列改性双氰胺中筛选出一种,将其与环氧树脂复配制成单组分潜伏性环氧树脂胶粘剂,利用差示扫描量热法(DSC)和红外光谱法(FT-IR) 对单组分环氧树脂固化体系的固化反应进行了分析和研究。结果表明,改性双氰胺与双氰胺相比,具有较高的活性,显著降低了固化反应的反应温度;所配制的单组分环氧树脂胶粘剂具有较长的贮存期和良好的固化性能。

| Abstract: | Several one-component epoxy resin,in which a series of modified dicyandiamide derivative acted as latent curing agent,were made up to decrease the curing temperature of epoxy resin with dicyandiamide. Curing reaction of these latent curing systems containing modified dicyandiamide were investigated with differential scanning calorimetry(DSC) and infrared analysis (FT-IR).The result showed that the modified dicyandiamide had higher reactivity in lower temperature. Moreover, the latent curing system possessed a long storage life and good curing properties. |
