| 中文摘要: |
| 将天然中空球状水铝英石在水中进行提纯分散处理，采用乳液共混共凝法制备中空球状水铝英石/SBR纳米复合材料，并对其性能进行研究。场发射环境扫描电子显微镜和透射电子显微镜观察表明，中空球状水铝英石原矿粉以聚集体形式存在，聚集体直径约为200 nm，组成聚集体的中空球状小颗粒直径约为13 nm；水铝英石在复合材料中分散良好。与采用直接共混法制备的复合材料相比，采用乳液共混共凝法制备的复合材料定伸应力较小，拉伸强度较大。 |

| The allophane was purified and dispersed in water，and then an allophane/SBR nanocomposite was prepared by latex compounding method，and its properties were investigated.It was found by ESEM and TEM that the original allophane existed in aggregates of hollow spherical particles with average size of about 13 nm，the size of aggregates was about 200 nm，and the dispersion of allophane in the nanocomposite was good.The modulus of nanocomposite prepared by latex compounding method was lower，but the tensile strength was higher，compared with those of composite prepared by direct compounding method. |
