It is difficult for alkali lignin of wheat straw produced by alkaline pulping to be widely used in industry because of its poor solubility and surface activities.
The result of performance test shows that the solubility of prepared waterborne epoxy resin decreases in organic solvent and increases in alkaline aqueous solution.
性能测试结果表明，所制的水性环氧树脂在有机溶剂中的溶解性变差，在碱性水溶液中的溶解性增强；
