0.22+6+11×0.20HT钢丝帘线在全钢载重子午线轮胎胎体中的应用

Application of 0.22+6+11×0.20HT Steel Cord in Carcass of Truck and Bus Radial Tire

研究0.22+6+11×0.20HT钢丝帘线在全钢载重子午线轮胎胎体中的应用。结果表明:与传统的3+9+15×0.175+0.15NT钢丝帘线相比,0.22+6+11×0.20HT钢丝帘线的单丝强度高,帘线直径和线密度小,渗胶性能好,耐磨损和耐疲劳性能优异;以0.22+6+11×0.20HT钢丝帘线替代3+9+15×0.175+0.15NT钢丝帘线用于12R22.518PR全钢载重子午线轮胎胎体中,生产工艺稳定性良好,可在保证轮胎强度的情况下,提高耐久性能,降低滚动阻力,同时可减小材料用量,降低生产成本。

The application of 0.22+6+11×0.20 HT steel cord in the carcass of truck and bus radial tire was investigated.The results showed that,compared with traditional 3+9+15×0.175+0.15 NT steel cord,0.22+6+11×0.20 HT steel cord possessed a higher monofilament intensity,smaller cord diameter and linear density,better rubber permeability,better wear resistance and fatigue resistance.Using 0.22+6+11×0.20 HT steel cord instead of 3+9+15×0.175+0.15 NT steel cord in the carcass of 12 R22.518 PR truck and bus radial tire,the process stability was good,the strength of tire could be ensured,the endurance was improved,and the rolling resistance was reduced.Meanwhile,the material consumption and production cost were reduced.
