溴化丁基胶乳乳化工艺研究

对制备溴化丁基胶乳的乳化工艺进行研究。优化乳化工艺条件为：乳化剂　油酸钾/十二烷基苯磺酸钠（用量比为5/2.5），溶液中BIIR质量分数　0.15，剪切速率　16 000　r·min^－１，乳化时间　30 min。采用优化工艺，溴化丁基胶乳的产率可达90%以上，胶乳各项性能能够满足涂覆和浸渍等工艺要求。;The emulsification process for preparation of bromobutyl rubber latex was investigated.The optimized emulsification conditions were as follows：emulsifiers were potassium oleate/sodium dodecyl-benzenesulfonate with a mass ratio of 5/2.5;mass fraction of BIIR in the solution was 0.15，shear rate was selected at 16 000 r·min^－１;the emulsified time was 30 min.The yield of bromobutyl rubber latex was more than 90% by using optimized process，and the properties of latex met the requirements of coating and dipping processes
