摘要
阐述了高转化率丁腈橡胶N32中试放大过程中的关键因素,确定了中间实验的聚合配方和工艺条件,制得了性能稳定的胶乳。通过控制脱气、凝聚、洗涤、干燥等工艺条件,保证了后处理过程的顺利进行。突破了转化率超过71%性能劣化的瓶颈,得到性能优良、贮存稳定性好的高转化率(75%～80%)丁腈橡胶N32新产品。
Engineering enlargement of the emulsion polymerization produced high conversion acrylonitrile-butadiene （brand of N32） and the effects of the pilot test adaptability were studied in this paper. Meanwhile,the polymerization recipe and processing conditions were mainly examined, the polymerization with a good reproducibility was steady and easy to control, and the latex with high property was obtained. Moreover, finishing process such as degasification, coagulation, washing and drying was discussed. The new emulsion polymerization technology without reducing the product properties adopted in this pilot test could increase conversion from 71% to 75% -80 %, which was a breakthrough over traditional production.
