| 中文摘要: |
| 研究国产恒粘天然橡胶（NR）在橡胶轨枕垫（简称轨枕垫）中的应用，并与进口同类产品进行对比。结果表明：国产恒粘NR和进口恒粘NR的生胶门尼粘度均符合指标要求；国产恒粘NR的基本性能均略优于进口恒粘NR；国产恒粘NR轨枕垫胶料与进口恒粘NR轨枕垫胶料的性能均达到指标要求，其中国产恒粘NR轨枕垫胶料的性能均优于进口恒粘NR轨枕垫胶料，采用国产CV-7恒粘NR的轨枕垫胶料的性能最优。 |

| Abstract：The application of domestic constant viscosity natural rubber（NR）in the rubber sleeper pad
（referred to as sleeper pad） was studied and compared with imported similar products. The results showed
that the Mooney viscosity of the raw rubber of domestic and imported constant viscosity NR met the index
requirements，and the basic properties of domestic constant viscosity NR were slightly better. The properties
of the sleeper pad compound made of either domestic or imported constant viscosity NR met the product
requirements. However，it was found that the properties of the sleeper pad compound using the domestic
constant viscosity NR were better，and the properties of the compound with domestic constant viscosity NR
CV-7 were the best. |
