探讨了羟基改性剂对PAE树脂的改性方式、改性剂用量，并对改性PAE树脂的增强性能进行分析。研究表明，羟基改性剂可以对PAE树脂进行改性，改性后不仅降低了PAE树脂的生产成本，还提高了PAE树脂的增干强效果。结果显示羟基改性剂对PAE树脂的末端改性优于过程改性；此时改性剂的较佳用量为15%；改性后的PAE树脂具有高的增干强性能及低的增湿强性能；当改性后的PAE树脂用量为0.5%时，与改性前相比，能够进一步提高纸张干抗张指数约7%，而降低湿抗张指数约23%，耐折度提高约13%，撕裂指数提高约25%，内结合强度提高约42%。%This paper researched on the modiifed method of PAE resin with hydroxy modiifer, discussed the dosage of modiifer, characterized modiifed PAE resin and studied the application of the modiifed PAE resin. The results showed that hydroxyl modiifer can undertake modiifcation of PAE resin, which can not only reduces the production cost of PAE resin, also improve the effect of the dry strength of PAE resin. Experimental results show that add hydroxy modiifer into the PAE resin product is the best process. Modified PAE resin has high dry strength performance and low strong wet strength performance. The better dosage of hydroxy modiifer is 15%. When modiifed PAE resin dosage was 0.5%, compared with traditional PAE resin can improve the paper dry tensile index about 7%, and reduce about 23% wet tensile index, folding resistance degree increases by about 13%, tearing index increases by about 25%, the bond strength increases by about 42%.
