| 中文摘要: |
| 研究全钢载重子午线轮胎胎面胶的门尼粘度与其他性能的相关性。结果表明：随着薄通次数的增大，胶料的门尼粘度减小，填料分散度提高，胶料的交联密度增大，－25和0 ℃时的损耗因子（tanδ）减小，60 ℃时的tanδ增大，硫化胶的硬度无明显变化，定伸应力先增大后减小，拉伸强度减小，阿克隆磨耗量增大；门尼粘度与门尼焦烧时间（t5和Δt30）、滞后性能、拉伸强度和阿克隆磨耗量有较强的线性关系。 |
| 英文摘要: |
| The correlation between Mooney viscosity and other properties of the tread compound of all-steel truck and bus radial tire was studies.The results showed that，as the thin-pass number of two-roll mill increased，the Mooney viscosity of the compound decreased，the dispersion degree of filler was improved，the crosslink density of the compound increased，the loss factor （tanδ） at －25 and 0 ℃ both decreased，tanδ at 60 ℃ increased.The hardness of the vulcanizates change little，the tensile stress first increased and then decreased，the tensile strength decreased，the Akron abrasion loss increased.There was a strong linear relationship between Mooney viscosity and Mooney scorch time （t5 and Δt30），hysteresis performance，tensile strength and Akron abrasion loss。 |
