摘要：研究以促进剂NS替代促进剂NOBS在斜交轮胎胎面胶和帘布胶中的应用效果。试验结果表明，以促进剂NS替代促进剂NOBS，在胶料硫化速度基本接近的情况下，胶料的焦烧时间略有缩短，硫化胶的物理性能和成品轮胎的耐久性能基本一致；不仅可以改善生产环境、减少污染，还能降低材料成本，具有较好的经济效益和社会效益。

Abstract:The application of accelerator NS instead of NOBS in the tread and carcass ply compounds of bias ply tire was investigated.The results showed that the similar curing rate was obtained by using NS in the tread and carcass ply compounds instead of NOBS,but the scorch time reduce somewhat;the physical properties of vulcanizate and the endurance of finished tire changed little;and the pollution of production environment improved significantly and the material cost reduced,thus the better economic and social benefits were obtained.

摘要：讨论骨架材料的规格、结构分布及工艺控制对全钢载重子午线轮胎性能的影响。胎体帘布采用带有外缠丝的3+9+15×022+015规格钢丝、胎体帘线密度在450~650 根·m-1范围内（帘线直径大于12 mm）以及胎体反包端点在成品外轮廓曲线的第2或3条装配线上等措施均有利于保证胎体强度；合理设计带束层结构，端点与胎侧肩部花纹距离取10 mm左右有利于消除应力过度集中；采用钢丝增强带有利于提高胎圈刚性。

(Dongfeng Gold Lion Tire Co., Ltd,Shiyan442053,China)
Abstract:The influence of the size and structural distribution of reinforcing material on the performance of BTR tire was investigated.The results showed that the carcass strength could be ensured by using 3+9+15×022+015 steel cord with outer wrapping filament,density of 450~650 ends·m-1and diameter greater than 1.2 mm,and placing the turnup end on the second or third fitting line of finished tire;the stress concentration in should area could be eliminated by designing the belt structure resonably and taking the distance from the belt ends to the tread patterns in shoulders of about 10 mm;and the bead stiffness could be increased by using the steel cord reinforcing strip.
