摘　　要：研究高结合苯乙烯含量丁苯橡胶(SBR)1586在矿用全钢载重子午线轮胎胎面胶中的应用,并与SBR1502对比。结果表明:SBR1586的结合苯乙烯含量明显大于SBR1502,与NR的相容性更好;在矿用全钢子午线轮胎胎面胶中用SBR1586等量替代SBR1502,混炼胶的门尼粘度降低,焦烧时间相当或延长,炭黑分散等级提高,加工性能和加工安全性改善;硫化胶的耐磨、抗切割、抗刺扎、耐热老化和耐臭氧老化性能提高,压缩疲劳温升降低,抗湿滑性能和干地抓着性能提高,滚动阻力略大,但在可接受范围内。The application of SBR1586 which had high bound styrene content in the tread compound of all-steel truck and bus radial tire for mining was studied and compared with SBR1502.The results showed that the bound styrene content of SBR1586 was significantly greater than that of SBR1502,and the compatibility of SBR1586 with NR was better.Using SBR1586 as an equivalent substitute for SBR1502 in the tread compound of all-steel truck and bus radial tires for mining,the Mooney viscosity of the compound decreased,the scorch time was equivalent or prolonged,the carbon black dispersion level increased,and the processability and processing safety were improved.The wear resistance,cutting resistance,puncture resistance,heat aging resistance,ozone aging resistance of the vulcanizates were improved,the compression fatigue temperature rise was reduced,wet skid resistance and dry grip performance were improved,and rolling resistance increased slightly,but within an acceptable range.
