环境友好型高固含量聚酰胺环氧氯丙烷湿强剂的研究

Study on Polyaminamide Epichlorohydrin Resin

聚酰胺环氧氯丙烷树脂（PAE）是应用较广泛的湿强剂，但存在固含量不高，有机氯含量高等缺点。采用改进的溶液聚合与有机胺后处理相结合的PAE合成工艺，制得的PAE产品中有机氯含量可小于0．1％。通过控制环氧化反应温度30℃，环氧化反应6h，可获得固含量50%～56％的低氯PAE湿强剂。

Polyaminamide epichlorohydrin resin （PAE） was a widely used wet strength agent which could be solidified in neutral environment. But it had several disadvantages such as low solid content and high organochlorine content. A new environment friendly technology involving copolymeration and amine post treatment to product PAE was studied. Organochlorine content of PAE was less than 0.1% and solid content could reach 50%-56% by controling epoxidation conditions under 30 ℃ and 6h.
