摘要
合成一系列二乙烯三胺和三乙烯四胺与三种丙烯酸酯加成物——新型环氧固化剂,采用红外光谱法证实了反应主要发生在丙烯酸酯的双键与多乙烯多胺的氨基上;并对固化后环氧树脂的冲击强度和剪切强度进行了测定,结果表明:环氧树脂的抗冲性能及粘接性能均有所改善。
A series pf novel curing agents which are the addition products of diethyltriamine or triethyltetramine with acrylates are synthesized for epoxy resins. IR spectra show that the addition reactions occur at the groups between the amino～groups in polyethylene polyamine and the double bonds of acrylate. Test results indicate that the properties of anti- impact and adhesion for the epoxy resins cured by the novel curing agents are improved.
