Study on Influence Factors of Particle Size and Distribution of Fluorine-contained Latex

Qin Zong-gen

Abstract

The fluorine-contained micro-latex for leather filling was prepared by seed emulsion polymerization.The results of FTIR indicate that fluorine-contained monomer participate in the polymerization.The particle size and distribution of fluorine-contained micro-latex were measured by Malvern ⅡC particle size analyzer.The main influencing factors such as the ratio of SLS/OP-10,NMA amount,polymerization temperature and neutralization temperature were investigated.The results show that when the ratio of SLS/OP-10 is 1.5,NMA amount is 4%,temperature of polymerization and neutralization is 55℃ and 50～55℃ respectively,the fluorine-contained micro-latex with smaller particle size and even distribution could be obtained.
