环氧Novolac胶液体系与极性溶剂反应性探究

Study on the Reactivity between Epoxy Novolac Varnish System and Polar Solvent

文章通过系列实验和测试证明,强极性溶剂DMF加速了酚醛树脂与环氧树脂之间的反应速率,但并未改变固化后产品的性能和结构,在整个反应过程中仅起到了催化剂的作用。

Basing on a series of experiment, the article proves the polar solvent DMF accelerates the reactivity speed between Phenolic resins and epoxy resins. However, It doesn＇t change character and configuration of the final cured product, and merely acts as the catalyzer during the whole reactivity.
