Analysis of the properties for epoxy curing agents with reactivity and toughening

  • 摘要: 以壬基酚和甲醛所形成的二聚体为原料,合成了一种新型结构的环氧固化剂双(2-羟基-3 -胺乙基胺甲基-5-壬基苯基)甲烷(BA),利用红外光谱(IR)、核磁共振谱(1HNMR)表征了产物结构.通过差 示扫描量热(DSC)研究了该固化剂的反应活性,确定固化剂最佳质量分数为43.19%.固化 树脂动态力学分析(DMA)表明,由于BA分子结构中存在正壬基,固化后会发生β- 松弛, 能够提高树脂韧性.力学性能测试发现BA固化树脂的冲击强度比普通芳香胺固化树脂提高了 36.91%,证明BA具有高活性和增韧双重效果.
