| 中文摘要: |
| 对现有大分子乳液插层法制备蒙脱土/SBR纳米复合材料技术进行改进。试验结果表明，使用低分子醇类混合物预分散有机蒙脱土，可使疏水的有机蒙脱土直接用于乳液插层法制备有机蒙脱土/SBR纳米复合材料；在SBR胶乳中加入少量带羟基的聚合物水溶液，能够使有机蒙脱土层间距扩大，有利于提高插层动力；超声波对聚合物插层没有明显的强化作用。 |
| 英文摘要: |
| The technology of montmorillonite/SBR composite prepared by macromolecular emulsion intercalation was modified.The test results showed that the hydrophobic organo montmorillonite，which was predispersed in a low molecular alcoholic mixture，was directly used to prepare organo montmorillonite/SBR nano-composite by emulsion intercalation；the distance between the layers of organo-montmorillonite was extended by adding small amount of water solution of a polymer with hydroxyl to SBR latex，which was beneficial to increase the intercalating power；and the ultrasonic had little effect on the enhancement of polymer intercalation. |
