摘　　要：研究3+8×0.21ST钢丝帘线在全钢轻型载重子午线轮胎胎体中的应用。结果表明:与3×0.24/9×0.225CCHT钢丝帘线相比,3+8×0.21ST钢丝帘线的直径和线密度小,粘合性能相当,压延及裁断工艺性能良好;以3+8×0.21ST钢丝帘线替代3×0.24/9×0.225CCHT钢丝帘线用于7.50R16LT全钢轻型载重子午线轮胎胎体中,轮胎的充气外缘尺寸、强度性能、高速性能和耐久性能符合国家标准要求,轮胎的舒适性更好,滚动阻力降低,单胎质量减小,成本降低。The application of 3+8×0.21ST steel cord in carcass of all-steel light truck and bus radial tire was studied.The results showed that,compared with 3×0.24/9×0.225CCHT steel cord,3+8×0.21ST steel cord had smaller diameter and cord density,equivalent adhesive performance,and good calendering and cutting process performances.By using 3+8×0.21ST steel cord to replace 3×0.24/9×0.225CCHT steel cord in the carcass of 7.50R16LT all-steel light truck and bus radial tire,the inflated peripheral dimension,strength,high-speed performance and durability met the requirements of national standards,the comfortability was better,the rolling resistance and the single tire mass were reduced,and the cost was lower.
