| 中文摘要: |
| 研究割龄3，13，20，24和28年5种RRIM600橡胶树天然胶乳粒径、生胶性能、混炼胶硫化特性及硫化胶物理性能。结果表明，割龄28年的橡胶树所得天然胶乳平均粒径最小，胶粒分布范围较窄，分散性较好；割龄20年的橡胶树生胶的塑性初值和门尼粘度较大，割龄20和28年的橡胶树硫化胶的拉伸强度和撕裂强度较大。 |
| 英文摘要: |
| The properties of natural rubber latex from RRIM600 with 3，13，20，24 and 28 tapping years were investigated，such as particle size of natural rubber latex，properties of raw rubber，curing characteristics of rubber compound and physical properties of the vulcanizates.The results showed that the average particle size of natural rubber latex from 28 tapping year rubber trees was the smallest and its particle size distribution had a narrow distribution range.Plastic initial value and Mooney viscosity of raw rubber from 20 tapping year rubber trees were higher.The tensile strength and tear strength of vulcanizate from 20 and 28 tapping year rubber trees were higher. |
