Abstract: Lacquer wax was used as the material to prepare high content solid lacquer wax emulsions modified by polyacrylic acid. In the present study,effect on emulsion properties,i.e.,solid content,centrifugal stability,and viscosity,was studied with different factors,including amounts of initiators,temperature,time,and emulsifier content. On this basis,the preparation process for the high content solid lacquer wax emulsions modified by polyacrylic acid was optimized by orthogonal test. The results showed that the optimal condition was determined as initiator concentration (sodium persulfate) of 0.3%,the reaction temperature of 90℃,the emulsifying time of 300min,and emulsifier content of 10%. The level of emulsion stability was one,the viscosity was 38500mPa·s and the solid content was 60% under the best condition.
