| 中文摘要: |
| 研究海南天然橡胶在全钢越野子午线轮胎胎面胶中的应用，并与马来西亚天然橡胶SMR20进行对比。结果表明：海南天然橡胶的杂质质量分数及氮质量分数均低于SMR20；将海南天然橡胶替代马来西亚天然橡胶SMR20用于越野轮胎胎面胶，胶料的拉伸性能、抗撕裂性能和抗切割性能稍好，脆性温度基本相同，生热较低；成品轮胎耐久性试验和高速性能试验顺利通过验证，海南天然橡胶轮胎的高速性能较好。 |
| 英文摘要: |
| The application of Hainan NR in the tread compound of off-road radial tire was investigated，and compared with Malaysia SMR20.The results showed that，the impurity concentration and nitrogen content of Hainan NR were lower than that of SMR20.When Hainan NR was used to replace SMR20 in the tread compound，the tensile strength，tear resistance and anti-cutting performance of the vulcanizate were slightly better，the brittle temperature was the same，and the heat build-up was lower.The finished tire with Hainan NR in the tread compound passed the durability and high speed performance tests，and had better high speed performances. |
