| 摘 要： | 以非离子型聚合物改性得到阳离子化剂,通过转型法成功制得了阳离子型分散松香施胶剂(CDRS),并对其性质进行了表征。CDRS为白色均一乳液,其Zeta电位为 26mV,体积平均粒径为0.271μm,一致性为0.404,粒径分布较好。在pH值6.0、Al2(SO4)3用量1%的条件下,CDRS对再生纸浆的施胶度为40s,施胶效果接近对照样品,耐老化性能则优于对照样品Hi-phase35。浊度实验和扫描电子显微镜观察表明,由于游离松香的皂化作用,CDRS的施胶效果随着pH值的升高而迅速下降。由于成本低,制备方法简单,在近中性条件下施胶效果较好。

| Abstract: | Cationic dispersed rosin sizing agent (CDRS) was prepared by changing ionic characteristics and its properties were characterized.The cationic agent used was modified from a non-ionic polymer.The product CDRS was a uniform emulsion of white color,+26 mV Zeta-potential,0.271 μm volume average particle diameter,0.404 uniformity and good particle diameter distribution.Under the condition of pH value 6.0 and Al2 (SO4) 3 dosage 1.0 %,CDRS showed comparable sizing degree of 40 s for regenerated pulp and better anti-aging permanence in comparison with the control (Hi-phase 35).The results of turbidity and SEM observation showed that the sizing efficiency of CDRS decreased quickly with the raising of pH value because of the free rosin saponification.The results indicate that CDRS has a promising future with its low cost,easy preparation and significant sizing effect under nearly neutral conditions. |
