补充资料:环氧中固化剂的重要性 最终决定环氧热塑性能
环氧树脂指的是一系列含有一个以上环氧基团的分子或低聚物。这些产品是固态的或者是稠度类似蜂蜜的液态,能够通过其中的环氧端基发生反应生成三维网络结构,从而赋予最终材料以刚度,硬度以及不流动性等性能。
最终制品通常具有以下性能:优异的电性能;由于含有极性基团,从而具有很好的粘接性能;收缩小;抗冲击性能好;抗吸湿性。这个系列的热固性塑料有很多的应用,如复合材料,涂料,粘和剂以及胶囊材料。选取的与环氧树反应的化学药品被称做固化剂(或硬化剂),且它通常含有与氮,氧,或硫相连的活泼氢。固化剂的选取需要考虑很多参数,而且在很大程度上将决定最终环氧热塑性材料的性能。
为了帮助您在具体的应用中做出正确的选择,您应该考虑以下几个方面:
环氧树脂固化剂的定义及作用机理;
复合材料制品中需要考虑的参数;
复合材料制品所用的工业化固化剂产品主要特征的描述。
