镍系胶光氧老化过程研究

Nickel-oxygen aging process of plastic optical

介绍了液体核磁共振波谱法(NMR)、傅里叶变换红外光谱法(FT-IR)、扫描电镜(SEM)和热失重分析(TGA)4种现代分析方法在橡胶光氧老化分析中的应用。NMR法能分析橡胶链中单元链节的组成、FTIR法能表征镍系胶在光氧老化过程中分子结构的动态变化结果,SEM能研究样品的聚集状态及低温下的结晶行为,TG研究样品的热稳定性等。

This work introduces the liquid nuclear magnetic resonance spectroscopy （NMR） , Fourier transform infrared spectroscopy （FT-IR）,scanning electron microscopy （SEM） and thermal gravimetric analysis （TGA） analysis of four mod- ern light oxygen in rubber aging analysis application. NMR method to analyze the chain unit segment of rubber composi- tion,FT-IR method can glue in the optical characterization of nickel oxide in the aging process dynamic variation of molecular structure,SEM to research samples of the aggregation state and low temperature crystallization behavior,TGA to indicated the thermal stability of samples.
