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.
Abstract
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,and 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 advantages.The comprehensive performance of NdBR-2# compound was better than that of NdBR-1# compound,the physical properties,rolling resistance,and dynamic mechanical properties were comparable,especially 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.
