| 摘 要： | 采用红外光谱、门尼粘度测定、橡胶加工分析等技术分析了长期自然贮存烟胶片的结构和加工操作性能,测定了硫化胶老化前后的力学性能.长期贮存后,烟胶片的分子链之间发生交联和氧化降解,导致门尼粘度、凝胶含量上升,加工操作性能下降,并且老化前后力学性能显著下降.

| Abstract: | The structure and processing properties of ribbed smoked sheet naturally stored for more than 35 years were analyzed using FTIR,Mooney viscosity determination,and rubber processing analyzer and the mechanical properties of vulcanizate before and after aging were also determined.The molecular crosslinkages and degradations of ribbed smoked sheet after long-term storage lead to the increases in Mooney viscosity and gel content and decreases in processing properties and mechanical properties before and after a... |
