合成了三种不同过渡金属羧酸盐与咪哩的配合物。将它与一种多羟基化合物共同作为促进剂。可以有效地降低双氰肢固化环氧树脂的温度。实现中温固化,井在室温时有良好的存储期。本文通过凝胶特性的测试和差热分析(DSC).对这三种过渡金属配合物促进环氧树脂体系的固化特性进行了探讨,并测试了其复合材料的基本性能。结果表明,复合材料的性能良好,与通常应用的中温固化环氧树脂基复合材料的性能相当。

Three kinds of transition metals salt of acetic acid and imldazole complex were synthesised. With the cooperative effect of poly-hydroxy compound, they were the effect accclerant to dicyanodiamide curing epoxy resin. These systems have lower curing temperature than dicyanodiamide curing epoxy without accelerant, can be cured at moderate temperature, and have good potlife at room temperature. Curing reaction of these three systems containing transition metal complex were investigated with gel propertics and differential scanning calorimetry (DSC). Properties of composites were lested. The results show that the curing systems had good properties andcould be used as matrix of composite.
