| 中文摘要: |
| 利用红外光谱法测试添加不同用量炭黑N234的橡胶基团特征峰红移（向低波数方向移动）情况，研究炭黑N234与橡胶的相互作用。结果表明：添加炭黑N234后，天然橡胶（NR）、溶聚丁苯橡胶（SSBR）、乳聚丁苯橡胶（ESBR）和顺丁橡胶（BR）红外光谱特征峰均发生不同程度的红移现象，NR的亚甲基特征峰红移程度最大，炭黑N234与NR的作用最强；随着炭黑N234用量增大，各橡胶不同基团的特征峰红移程度不同，不同基团与炭黑N234的相互作用不同；橡胶并用时基团特征峰红移程度基本不受影响；添加炭黑N234的硫化并用胶的基团特征峰红移规律与混炼并用胶相同。 |
| 英文摘要: |
| The interaction between carbon black N234 and the rubber was studied by infrared spectroscopy（IR）. The red shift（shift to low wavenumber） of group characteristic peak of the rubber with different dosages of carbon black N234 was observed. The results showed that with the addition of carbon black N234，the IR characteristic peaks of natural rubber（NR），solution polymerized styrene-butadiene rubber（SSBR），emulsion polymerized styrene butadiene rubber（ESBR） and butadiene rubber（BR） all presented a red shift in different degrees. Due to the strong interaction between carbon black N234 and NR， the red shift degree of methylene group characteristic peak of NR was the largest. With the increase of carbon black N234 amount，the red shift degrees of different group characteristic peaks of rubber were different，and the interaction between different groups of rubber and carbon black N234 was different. The red shift degree was not affected by the blending of rubbers. With the addition of carbon black N234，the red shift results of group characteristic peaks of the vulcanized blends were the same as the unvulcanized ones. |
