摘要:
针对高抗冲聚苯乙烯(HIPS)生产过程中出现的粒子发灰现象,从原料、聚合和脱挥单元分析了原因,并采取了相应对策。结果表明:原料苯乙烯的含氧储存环境、聚丁二烯橡胶(BR)中挥发分及氯离子含量高是导致产品粒子发灰的主要原因;将苯乙烯存储由有氧环境改为氮气环境,严格控制 BR 中挥发分质量分数小于 0.5%,且优选线型低顺式BR,可有效降低 HIPS 产品粒子发灰的几率。
Abstract:
In response to the ash formation phenomenon during the production of high impact polystyrene (HIPS)particles, the reasons were analyzed from the perspectives of raw materials, polymerization, and devolatilization units, and corresponding countermeasures were taken. The results showed that the oxygen containing storage environment of raw material styrene, high volatile matter and chloride ion content in polybutadiene rubber (BR) were the main reasons for product particle ashing. Countermeasures such as changing the storage of styrene from an aerobic environment to a nitrogen environment, strictly controlling the mass fraction of volatile matter in BR at less than 0.5%, and selecting linear low cis-BR could effectively reduce the probability of particle ash formation in HIPS products.
