| 中文摘要: |
| 研究无锌加工助剂HT207在轿车轮胎胎面胶中的应用。结果表明：在胎面胶中加入加工助剂HT207，胶料的门尼粘度和剪切粘度减小，门尼应力松弛时间缩短，硫化胶的硬度变化不大，耐磨性能下降，老化后硫化胶的物理性能相当，损耗因子减小，轮胎的滚动阻力降低，胶料的半成品表面外观质量改善；随着加工助剂HT207用量的增大，胶料的门尼粘度、储能模量和剪切粘度减小，门尼应力松弛时间缩短，硫化胶老化前的硬度和老化后的物理性能相当。 |
| 英文摘要: |
| The application of zinc-free processing aid HT207 in tread compound of passenger car tire was studied.The results showed that by adding processing aid HT207 in tread compound，the Mooney viscosity and shear viscosity of the compound decreased，the Mooney stress relaxation time was shortened，the hardness of the vulcanizate changed little，the wear resistance decreased，the physical properties of the vulcanizate after aging were similar，the loss factor decreased，the rolling resistance of tire decreased，and the surface appearance quality of semi-finished compound improved.As the dosage of processing aid HT207 increased，the Mooney viscosity，storage modulus and shear viscosity of the compound decreased，the Mooney stress relaxation time was shortened，and the hardness before aging and the physical properties after aging were similar.rolling resistance is lower. |
