| 中文摘要: |
| 介绍一种新型覆盖带的设计，并与普通覆盖带进行对比。新型覆盖带采用3层钢帘网结构，提高了覆盖带的整体刚度。新型覆盖带采用钢帘网替代覆盖带传统的横向方钢条结构，减少钢条前处理、铺设和填充胶条工序，整个生产过程效率提高5倍。新型覆盖带纬向下挠度低，优化配方设计的覆盖胶耐臭氧老化性能和耐热老化性能好，粘合胶粘合性能较好，覆盖带使用寿命延长。新型覆盖带有明显的制造优势。 |
| 英文摘要: |
| A new type cover belt was introduced and compared with the common cover belt.The new type cover belt adopted three-layers steel cord breaker，which improved the overall stiffness of the cover belt.Steel cord breakers were used instead of the traditional transverse square steel strip，the steel strip pretreatment and laying processes as well as rubber strip filling processes were removed，the production efficiency was improved by five times.The new type cover belt had lower latitude deflection.As formulation design optimization of cover compound and adhesive compound，the ozone and heat aging resistance were improved，and service life of the cover belt was prolonged.The new type cover belt had obvious manufacturing advantage. |
