摘要:以尺寸稳定型聚酯(DSP)和改性锦纶66帘线作为轿车和轻型载重子午线轮胎的胎体骨架材料,对比分析轮胎外缘尺寸和静负荷特性。结果表明,DSP胎体轮胎与改性锦纶66胎体轮胎相比,轮胎静态断面宽小;耐久性试验后,DSP胎体轮胎断面宽变化率小于改性锦纶66胎体轮胎;高速试验后,DSP胎体轮胎断面宽变化率大于改性锦纶66胎体轮胎;一定气压和负荷条件下,DSP胎体轮胎下沉率大,印痕面积小,接地区域单位面积平均压力大,轮胎硬度因数大。DSP胎体轮胎尺寸稳定性好,均匀性好,但操纵性和胎面耐磨性比改性锦纶66胎体轮胎稍差。

Abstract:The dimensionstable polyester (DSP) and modified nylon 66 cords were applied in the carcass ply of PCR tire and
LTR tire,and the overall diameters and static loading capacities of test tires were compared.The results showed that compared
to modified nylon 66 cord tire,DSP cord tire featured smaller static crosssectional width,lower change rate of crosssectional width after endurance test,higher change rate of crosssectional width after high speed test;under a certain
inflation pressure and loading capacity,DSP cord tire possessed higher deflection,smaller footprint,larger even pressure
intensity at groundcontact area and greater hardness factor;and DSP cord tire had better dimension stability and
uniformity,but somewhat poorer handling quality and tread life.

摘要:研究2+7×0.34HT钢丝帘线在载重子午线轮胎带束层中的应用。结果表明,与3+9+15×0.22+0.15钢丝帘线相比,2+7×0.34HT钢丝帘线橡
胶渗透性能和耐疲劳性能提高,且等强度下帘线用量减小;以2+7×0.34HT钢丝帘线替代3+9+15×0.22+0.15钢丝帘线应用于10.00R20 16PR轮胎带束层中,成品轮胎的耐久性能提高,同时可减小轮胎质量,降低制造成本。

Abstract:The application of 2+7×0.34HT steel cord in BTR belt was investigated.The results showed that compared to 3+9+15×0.22+0.15 steel cord,2+7×0.34HT steel cord featured improved rubber penetration and fatigue property,and less cord
consumption in a belt with the same intensity;and the endurance of finished tire improved,and the weight and production cost
of tire reduced by replacing 2+7×0.34HT steel cord for 3+9+15×0.22+0.15 steel cord in the belt of 10.00R20 16PR tire.

Abstract:The application of the antirecovery agent DL268 in the shoulder pad of 11.00-20 18PR tire was investigated.The
results showed that the antireversion of vulcanizate improved significantly,the modulus at 300%,tensile strength and
resilience increased,the compression fatigue temperature rise decreased and the thermal aging property improved by using 2
phr antirecovery agent DL268;and the endurance of finished tire improved significantly and the shoulder seperation
decreased.
