摘要
采用曼尼希反应对芳香胺、脂环胺进行改性,以改善其固化性能。应用两步法合成得到的改性脂环胺,固化速度快、耐热性能好、综合性能优异。其中改性邻二胺甲基环戊烷与E51完全固化后在℃的剪切强度达到150 8.11 MPa。讨论了不同胺类对反应产物的胺值、初固时间和E51固化物剪切强度的影响。
In this work, the aromatic amine and alicyclic amine were modified by the Mannich reaction to improve their curing performance. The modified alicyclic amine prepared by two-step method have excellent overall performance, including fast curing and good heat resistance. The completely cured E51 epoxy resin with the modified ortho-diamino methylcyclo pemtane(TDC) had the shear strength of up to 8.11 MPa at 150 ℃.The influence of different amines on the amine value,preliminary cueing time and shear strength of cured E51 resin was discussed.
