摘要
研究氯丁橡胶SN121的基本性能,并与国内同类产品山纳CR121及国外同类产品GW和GS进行对比。结果表明:SN121在开炼机上的包辊性能和在密炼机中的混炼性能良好,与GW和GS相近,优于CR121,内在质量均匀、稳定;门尼焦烧时间和t10较长,具有较好的加工安全性,硫化速度适中;门尼粘度与CR121和GW相当;拉伸强度与GW和GS相近,高于CR121。SN121的综合物理性能与GW和GS相近,优于CR121。
The basic properties of chloroprene rubber SN121 was investigated and compared with Shanna CR121and similar foreign products GW and GS. The processing property of SN121 in two roll mill and inner mixer was good,similar to GW and GS, and better than CR121. The product quality was uniform and stable. The Mooney scorch time and t10 were long, indicating good processing safety, and the curing speed was moderate. The Mooney viscosity was similar to CR121 and GW. The tensile strength of the vulcanizates was similar to GW and GS, and higher than CR121.Overall, the comprehensive physical properties of SN121 were close to foreign products GW and GS, and better than domestic product CR121.
