| 中文摘要: |
| 针对帘布剥离力受测试系统影响较大的问题，设计一种试验方法用于测试载重子午线轮胎钢丝帘布间的粘合力、成品轮胎帘布层间剥离力。分析得出，不同规格帘布的粘合力差别比较明显，粘合力与帘线结构和帘布压延厚度有关。在不同的老化条件下，帘布间粘合力均下降，其中热老化后降幅最大，其次是湿热老化；盐水老化腐蚀试验显示，带束层应尽可能选择全渗胶帘线结构。改进压延帘布配方，可提高钢丝帘布间剥离力。成品剥离测试结果显示：轮胎使用后，胎体与1#带束层剥离力明显下降，气密层气密性改进后，胎体与1#带束层的剥离力明显提高。 |
| 英文摘要: |
| In this study, a test method was developed to test the adhesive force between steel cord fabrics of truck and bus radial tire and peeling strength between cord plies of the finished tire，which reduced the large test variation of peeling strength between cord plies using the regular test system.The testing results showed that the adhesive force of different cord fabrics changed a lot，which depended on cord type and calendaring thickness of cord fabric.The adhesive force between cord fabrics all decreased in different aging conditions.The adhesive force after thermal ageing had the largest decline followed by damp and heat aging.The salt water corrosion test results showed that full rubber penetration structure was the best belt structure.It was also found that improvement of the rubber compound could increase the peeling strength between steel cord fabrics.The peeling test result of finished tire showed that，after using，the peeling strength between carcass and 1# belt dramatically declined.After the airtightness of inner liner was improved，the peeling strength between carcass and 1# belt increased significantly. |
