Article Preview

Cationic polyacrylate emulsion was prepared in lab by semi-continuous seed pre-emulsification process. After the single factor experiments, the orthogonal experiments were made to get the optimal polymerization processes. Through the single factor experiment and further the orthogonal experiment optimization, it shows that the sequence of the effect of these factors on the viscosity of emulsion is drop time > reaction time > reaction temperature. The sequence of the effect of these factors on the solid content of emulsion is drop time > reaction time > reaction temperature. The sequence of the effect of these factors on the conversion rate of emulsion is drop time > reaction time > reaction temperature. The obtained best polymerization processes are the drop time is 1.5h, the reaction time is 5h, the reaction temperature is 85 °C. Under the best polymerization processes, the properties of the emulsion are the solid content is 35.40%, the conversion rate is 96.33%, the viscosity is 456.67mPa.s, the particle size is 490.20nm, the Zeta potential is 30.50 mV and pH is 2.50.
