摘　　要：通过对SBS小釜聚合闪爆事故原因的分析,得出造成事故的主要原因是SBS小釜聚合操作流程及试验室设计不合理,导致放料过程中,环戊烷蒸气在有限空间聚集,在静电作用下引发闪爆。通过采取聚合工艺优化、试验室改造、设备改进等措施,对SBS小釜聚合试验起到了较好的安全保障作用。Through a cause analysis on the flash explosion in SBS small kettle polymerization,it is found out that the main reason for the accident is that the operation process and laboratory design of the SBS small kettle polymerization are irrational,which causes the gathering of cyclopentane vapor in a limited space during the discharge process and this leads to flash explosion under electrostatic interaction.After adopting such measures as the optimization of the polymerization process,transformation of the laboratory and improvement of the equipments,the safety of the test on SBS small kettle polymerization can be guaranteed well.
