Abstract:Acrylate modified polyvinyl acetate emulsion was prepared with copolymerization method. Orthogonal test was employed to investigate the effect of some major factors such as protective colloid、surfactant and modifier on the viscosity of emulsion. The results showd that these factors was in the decreasing order:protective colloid>surfactant>modifier. The polyvinyl acetate emulsion product obtained under the optimum condition had the following performance:The pH valueare was 5~6,viscosity 600~800 mPa·s,good acid and alkaline resistance,freeze-thaw stability and mechanical stability. |
Key words:copolymerization;orthogonal test;vinyl acetate emulsion;viscosity |
