| 中文摘要: |
| 基于半钢子午线轮胎胎面胶配方，将两种高门尼粘度钕系顺丁橡胶（NdBR）{记为NdBR-1#和NdBR-2#，门尼粘度[ML（1＋4）100 ℃]分别为67和72，相对分子质量分布指数分别为3.26和2.31}与溶聚丁苯橡胶（SSBR）和天然橡胶（NR）并用，并与镍系顺丁橡胶（牌号BR9000）和NdBR（牌号CB22）作对比，研究高门尼粘度NdBR/SSBR/NR胎面胶的性能。结果表明：在BR/SSBR/NR三胶并用时，高门尼粘度NdBR的应用优势较明显；NdBR-2#胶料的综合性能优于NdBR-1#胶料，物理性能、滚动阻力及动态力学性能相当，抗裂口增长性能、抗切割性能和耐老化性能尤其突出，明显优于CB22胶料。NdBR-2#更适用于BR/SSBR/NR并用体系。 |
| 英文摘要: |
| Based on the tread compound formula of steel-belted radial tire，two kinds of high Mooney viscosity neodymium butadiene rubber（NdBR，denoted as NdBR-1# and NdBR-2#，with Mooney viscosities of 67 and 72，and relative molecular mass distributions index of 3.26 and 2.31，respectively）were blended with solution polymerized styrene-butadiene rubber（SSBR） and natural rubber（NR），using nickel butadiene rubber BR9000 and NdBR CB22 as the comparison samples，the properties of high Mooney viscosity NdBR/SSBR/NR tread compounds were investigated.The results showed that，when BR/SSBR/NR were blended，high Mooney viscosity NdBR had obvious application advantage.The comprehensive properties of NdBR-2# compound were better than that of NdBR-1# compound，the physical properties，rolling resistance，and dynamic mechanical properties were comparable，in particular，the crack growth resistance，cutting resistance，and aging resistance were outstanding，obviously superior to that of CB22 compound.NdBR-2# was more suitable for the BR/SSBR/NR tread formulation system. |
