通过溶液乳化法制备了溴化丁基胶乳,使用激光粒度仪测试了不同工艺阶段胶乳的平均粒径,结果表明所制得的固含量约为50%的离心浓缩胶乳的平均粒径为0.645μm。并进一步研究了乳化剂用量和橡胶溶液浓度对胶乳产率的影响,从而确定了溴化丁基胶乳制备的最佳工艺条件。
Bromobutyl latexes were prepared by solution emulsification. The average particle sizes of the latexes in different process stages were measured by laser particle sizer. The results showed that the average particle size of the centrifuged latexes with the solid content of about 50% was 0.645μm . The effects of the amount of emulsifier and the concentration of rubber solution on the yield of latex were further studied. The optimum conditions for the preparation of brominated butyl latex were determined.
