Effect of Chitosan Dosage on the Physical Property of Modified Cationic Styrene-Acrylate Emulsion Sizing Agent
For improving environmental friendliness,cationic styrene-acrylate emulsion sizing agent was modified by chitosan,chitosan dosage was determined to be not more than 0.5%of the weight of cationic styrene-acrylate emulsion sizing agent.Meanwhile,effect of chitosan dosage on the static stability,centrifugal stability,dispersion,pH,viscosity,surface tension and solid content of modified cationic styrene-acrylic emulsion sizing agent was studied,and the results showed that the sizing agent had high static stability and centrifugal stability,excellent dispersion,stable pH,increasements of viscosity,surface tension and solid content,while paper whiteness decreases gradually.
