| 中文摘要: |
| 研究用核磁共振（NMR）法纵向弛豫时间（t1）表征胶料中生胶并用比及白炭黑用量。对不同生胶、白炭黑或炭黑填充的硫化胶和未硫化胶的t1测试和分析得出：不同生胶具有不同的t1；同种生胶，测试温度越高，t1越长；硫化胶的t1与生胶并用比及白炭黑用量有极高的相关性。NMR法测试胶料t1可作为快速定量分析胶料生胶并用比及白炭黑用量的新方法。 |
| 英文摘要: |
| In this study，the longitudinal relaxation time（t1） in nuclear magnetic resonance （NMR） test of Compound was used to characterize the rubber blending ratio and the silica loading level.The test results of t1 for different rubber，un-vulcanized or vulcanized rubber filled with different amount of silica or carbon black showed that different rubber possessed different t1 value；for the same rubber material，t1 was extended with the increase of test temperature；and the t1 value of the vulcanized rubber showed strong correlation with the rubber blending ratio and silica loading level.It provided a novel rapid quantitative method to analyze the rubber blending ratio and the silica loading level in the vulcanized rubber. |
