Preparation of Cationic Dispersed Rosin Sizing Agent
摘要
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.关键词
