| 中文摘要: |
| 以促进剂CBS用量作为变量，研究硫黄硫化体系对天然橡胶（NR）性能的影响。结果表明：促进剂CBS用量增大，混炼胶的F max和F max－FL 增大， t10和t90缩短，硫化胶的压缩生热最低，压缩变形较小；促进剂CBS用量为2.5份的有效硫黄硫化体系硫化胶的拉伸性能最好，促进剂CBS用量为3份的有效硫黄硫化体系硫化胶的tan δ 峰值最小；在90 ℃以上，促进剂CBS用量为2和2.5份的半有效硫黄硫化体系硫化胶的热导率较高。 |

| he effect of sulfur vulcanization systems on the properties of natural rubber（NR） was studied using accelerator CBS amounts as variables.The results showed that with the increases of accelerator CBS amount，the F max and F max－FL of the compound increased， t10 and t90 decreased，the compression heat generation of the vulcanizate was the lowest，and the compression deformation was smaller.The tensile performance of the vulcanizate with efficient sulfur vulcanization system with accelerator CBS amount of 2.5 phr was the best，and the tanδ peak value of the vulcanizate with efficient sulfur vulcanization system with accelerator CBS amount of 3 phr was the minimum.At temperatures above 90 ℃，the thermal conductivities of semi effective sulfur vulcanization systems with accelerator CBS was amounts of 2 and 2.5 phr were higher. |
