| 中文摘要: |
| 研究多功能橡胶助剂HT918在载重子午线轮胎胎面胶中的应用。结果表明：在胎面胶中加入多功能橡胶助剂HT918，胶料的t10和t90缩短，交联密度增大，抗硫化返原性提高；硫化胶的定伸应力和拉伸强度增大，拉断伸长率和撕裂强度减小，耐老化性能、耐屈挠性能和耐磨性能提高，压缩生热降低；轮胎的抗湿滑性能和耐久性能提高，滚动阻力降低；多功能橡胶助剂HT918的综合性能等同或优于国外同类产品。 |
| 英文摘要: |
| The application of multi-functional rubber additive HT918 in the tread compound of truck and bus radial tire was investigated.The results showed that，by adding multi-functional rubber additive HT918 in the tread compound，the t10 and t90 of the compound were shortened，the crosslinking density increased，and the anti-reversion property was improved.The modulus and tensile strength of the vulcanizate increased，the elongation at break and tear strength decreased，while the aging resistance，flexural resistance and wear resistance were improved，the compression heat build-up decreased.The wet skid resistance and durability of the tire was improved and the rolling resistance decreased.The comprehensive properties of multi-functional rubber additive HT918 were equal to or better than the same kind of foreign product. |
