摘要
通过引入环氧树脂 (EP)使水性聚氨酯中具有了交联结构 ,涂膜的耐水性、耐溶剂性以及机械性能都得到提高。研究了EP的引入方法及其用量对分散体和涂膜性能的影响。
The modified polyurethane dispersion was prepared by adding epoxy resin.Compared with the non-modified polyurethane,the water resistance,solvent resistance and mechanical properties of the epoxy-modified polyurethane were greatly improved.The effects of epoxy content and its addition mode on the state of dispersion and mechanical properties of the cast films were studied.
