中文摘要: |
本文主要介绍固体核磁共振法(固体13C-NMR)、质谱法(MS)和傅里叶变换红外光谱法(FTIR)的近代分析方法在橡胶硫化胶分析中的应用。NMR法能分析橡胶链中单元链节的组成、结构,MS法能分析橡胶基材及结构,橡胶中的有机配合剂和橡胶的表面性质,FTIR法能分析橡胶硫化过程的返原作用和老化过程中的基团变化情况等。 |
英文摘要: |
The application is introduced of some modern methods,such as solid 13C nuclear magnetic resonance(NMR),mass spectrograph(MS)and Fourier transform infrared spectroscopy(FTIR)in the analysis of various vulcanizates. NMR can be used in determining the composition and structure of the chain unit of rubber;MS can be used in determining the type and structure of the rubber,and the boundary effect of rubber and compounding ingredients in vulcanizates;FTIR can be used in analysing the reversion of vulcanizates and their changes during ageing. |
