| 中文摘要: |
| 研究了钴盐品种和用量对NR胶料性能及子午线轮胎帘布胶-镀铜钢丝帘线粘合力的影响。结果表明，加入不同品种钴盐的胶料性能无明显差别;随着过硫化时间的延长，含钴盐CN-10和CN-16的胶料与镀铜钢丝帘线之间的粘合力明显下降;经热空气老化后不同品种钴盐均保持较好的耐热性能;经湿热蒸汽老化后钴盐CN-20.5和680C具有较高的粘合力保持率。随着钴盐CN-20.5用量的增大，可获得较高的初始粘合力，但耐热空气老化和耐湿热蒸汽老化性能下降明显，其用量以0.7-1.2份为最佳。 |
| 英文摘要: |
| The effect of cobalt salt type and level on the properties of NR compound and the adhesion strength between the cord compound and the brassplated steel cord in radial tire was investigated.The results showed that the cobalt type had little effect on the compound properties;the adhesion strength between the CN-10 (cobalt naphthenate)-containing compound or CN-16 (cobalt stearate)-containing compound and the brassplated steel cord decreased significantly as the overcure time increased;the compounds with different types of cobalt salts had better heat resistance after heat air aging;and the compounds with CN-20.5(cobalt neodecanoate) or 680C(cobalt boroacylate) had higher
adhesion strength retention after steam aging.The higher original adhesion strength could be obtained，but the heat air aging properties and steam aging properties decreased significantly as the level of CN-20.5 increased;and the optimal balanced adhesion properties were obtained when 0.7一1.2 phr of cobalt salt was used. |
