| 中文摘要: |
| 对乳液法制备的SBR粘土纳米复合材料的气密性进行了研究，结果表明:SBR粘土纳米复合材料的气密性优于传统填料填充的硫化胶，且随温度的变化较小；填料的用量、形状以及与橡胶的结合活性是影响气密性的主要因素；填充20份粘土的纳米复合材料气密性优于NR/SBR内胎，比IIR内胎差。 |
| 英文摘要: |
| The air-tightness of the clay/SBR nanocomposite prepared byMixing clay and SBR latex was investigated.The results showed that the air-tightness of clay/SBR nanocomposite was better than that of the traditional filler-filled SBR vulcanizate，and changed fewer with the temperature；the airtightness wasMainly influenced by the factors，such as addition level，shape and reaction activity to rubber of filler；and the tightness of inner tubeMade from nanocomposite filled with 20 phr of clay was better than that of NR/SBR inner tube，but inferior to that of IIR inner tube. |
