顺丁橡胶聚合挂胶的原因分析及解决方法

The Reason Polymerized Butadiene Rubber Hanging Plastic Analysis and Solutions

对目前国内采用镍系催化剂溶液聚合法生产顺丁橡胶过程中挂胶严重的原因进行了分析,并提出了解决办法,在原材料和催化剂质量合格并控制合适加水量的基础上,降低催化剂用量,控制好催化剂铝与硼的比值和稳定好聚合反应,就能减少凝胶生产量,减轻挂胶,提高产品质量。

At present, the use of nickel - based catalyst solution polymerization process of butadiene rubber production hanging plastic serious analysis of the causes and proposed solutions in the quality of raw materials and catalyst qualified and control on the basis of the appropriate amount of water, reducing the amount of catalyst, good control of aluminum and boron catalyst ratio and stable good polymerization reaction, the gel can reduce production, reduce the hanging plastic, improve product quality.
