| 中文摘要: |
| 研究充油丁苯橡胶（SBR1712）替代非充油丁苯橡胶（SBR1502）在工程机械轮胎胎面胶中的应用。结果表明：采用SBR1712替代SBR1502，胶料的混炼排胶温度降低，混炼工艺性能和成型工艺性能良好，硬度、300%定伸应力和拉断伸长率基本不变，拉伸强度和撕裂强度稍有下降，但保持在较高的水平，阿克隆磨耗量和切割减量变化不大，压缩生热大幅降低；成品轮胎胎面胶的物理性能符合国家标准要求，轮胎的耐久性能明显提高。 |
| 英文摘要: |
| In this study，oil-extended styrene butadiene rubber（SBR1712） was applied in the tread compound of OTR tire replacing non-oil-extended styrene butadiene rubber（SBR1502）.The experimental testing results showed that with SBR1712，the mixing temperature and discharging temperature of rubber compound were reduced，the mixing properties and molding properties of the compound were good，the hardness，modulus at 300% elongation and elongation at break of the vulcanizates were basically kept unchanged，the tensile strength and tear strength decreased slightly but remained at high levels，Akron abrasion loss changed little，and the compression heat build-up was greatly reduced.The tread compound physical properties of the finished tire met the requirements of national standards and the endurance performance was significantly improved. |
