摘要在环氧－酚醛胺体系中使用端环氧基聚氨酯醚、聚硫橡胶、液体丁腈橡胶等活性增韧剂，通过对固化物剪切强度、弯曲弹性模量及断裂强度的测试对比，可以看出不同增韧剂效果不同。

• Filling flexibilizer, such as epoxy terminal block, polyurethane ether structure, thiokol and liquid CTBN to the system of expoxy-Mannich amide, through the test on shear strength, bounding elasticity modulus and break strength of cured products, the different fuction could be found using different flexibilizers.
