Function of Glycerin Rosin Ester in Stability and Sizing Development of Cationic Rosin Size

摘要：

Glycerin rosin ester is an important rosin extender used to prepare emulsion type neutral rosin sizes.In this paper,the function of glycerin rosin ester in stabilization and sizing development of cationic rosin size were investigated by using conventional sizing measurement,ESEM and XPS.The results show that glycerin rosin ester can significantly reduce the surface carboxyl groups of cationic rosin size,which prevents the aggregation of rosin particles and improves the stability of cationic rosin size.The improvement of the stability of cationic rosin size may enhance its sizing efficiency.However,the reduction of carboxyl groups by glycerin rosin ester lowers the sizing performance of cationic rosin size.Therefore,the addition levels of glycerin rosin ester have to be compromised between the stability and the sizing performance of cationic rosin size.
