Among them , sea - island structure flexibilizer had good synthetical properties 相比较而言,端环氧基聚氨酯醚海岛结构增韧剂的综合性能较好。
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 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。
