| 中文摘要: |
| 采用裂解-气相色谱/质谱（Py-GC/MS）法研究子午线轮胎常用的4种橡胶天然橡胶（NR）、丁苯橡胶（SBR）、顺丁橡胶（BR）和溴化丁基橡胶（BIIR）及其并用胶NR/SBR，SBR/BR，NR/BR和NR/BIIR，确定4种橡胶的特征裂解产物，建立Py-GC/MS法定性定量分析未知硫化胶中并用橡胶的方法。结果表明，本方法在未知硫化胶分析时定性分析非常准确，可做半定量分析，重复性良好，相对标准偏差为0.01%。 |
| 英文摘要: |
| Pyrolysis gas chromatography/mass spectrometry（Py-GC/MS） method was used to study four kinds of rubber commonly used in radial tire，natural rubber（NR），styrene butadiene rubber（SBR）， butadiene rubber（BR），brominated butyl rubber（BIIR） and their blends NR/SBR，SBR/BR，NR/BR and NR/BIIR.The characteristic pyrolysis products of four kinds of rubber were determined，and the Py-GC/MS method for qualitative and quantitative analysis of blended rubber in unknown vulcanizate was established.The results showed that the method was very accurate in the qualitative analysis of unknown vulcanizate，cound be used for semi-quantitative analysis，had good repeatability，and the relative standard deviation was 0.01%. |
