中文摘要: |
研究化学改性蛭石粉填充溴化丁基橡胶(BIIR)的性能。结果表明:与填充未改性蛭石粉的BIIR胶料相比,填充改性蛭石粉的BIIR胶料的硫化速度明显提高,最大转矩增大,硫化胶的硬度、拉断伸长率和撕裂强度均有所提高,拉伸强度显著提高,损耗因子减小,玻璃化温度升高;填充改性蛭石粉的BIIR硫化胶的断面有较多脊痕线,且分布没有规律,
断面规整性差。化学改性能够改善蛭石粉的分散性,改性蛭石粉作为填料可以提高BIIR硫化胶的性能。 |
英文摘要: |
The properties of brominated butyl rubber(BIIR) filled with chemically modified vermiculite powder were studied. The results showed that,compared with the BIIR compound filled with unmodified vermiculite powder,the curing speed,maximum torque,hardness,elongation at break and tear strength of the BIIR compound filled with modified vermiculite powder increased,tensile strength was improved significantly,tanδ decreased,and Tg increased. Many ridge lines appeared on the fractured surface of the vulcanizates with irregular distribution. Chemically modification could improve the dispersion of vermiculite powder. Using modified vermiculite powder as filler,the properties of BIIR vulcanizate were improved. |
