| 中文摘要: |
| 介绍橡胶交联密度的测试方法及其应用研究进展。橡胶交联密度的测试方法主要包括化学法、平衡溶胀法、核磁共振法、应力-应变法和原子力显微镜法，其中核磁共振法具有广阔的应用前景。交联密度的测定结果可以表征硫化胶交联程度，用于研究硫化和补强体系及硫化工艺对硫化胶物理性能的影响；老化过程中交联密度的测定可以表征硫化胶耐老化性能，研究配方组分及老化条件对硫化胶性能的影响。今后应加强橡胶交联密度测定方法的规范化和标准化，提高测定结果的可靠性。 |
| 英文摘要: |
| This paper introduced the test method of rubber cross-linking density and its application research progress.The test methods of rubber cross-linking density mainly included chemical method，balanced swelling method，nuclear magnetic resonance method，stress-strain method and atomic force microscopy method.Among them，nuclear magnetic resonance method had broad application prospects.The measurement result of the cross-linking density could characterize the cross-linking degree of the vulcanizate and was used to study the influence of the curing system，reinforcement system and curing process on the physical properties of the vulcanizate.The measurement of the cross-linking density during the aging process could characterize the aging resistance of the vulcanizate，and was used to study the influence of formula components and aging conditions on the properties of the vulcanizate.In the future，the normalization and standardization of rubber cross-linking density measurement methods should be strengthened to improve the reliability of the measurement results. |
