摘要
研究有机钴盐品种和用量对载重子午线轮胎带束层胶料 镀铜钢丝帘线粘合力的影响。结果表明 ,加入硬脂酸钴、硼酰化钴和癸酸钴任何一种钴盐 ,胶料初始粘合力均较高 ,但硬脂酸钴胶料老化后的粘合性能较差 ,癸酸钴胶料的粘合性能略好 ,癸酸钴理想用量为 0 .5 8～ 0 .81份。间 /甲 /白 /钴粘合体系胶料老化前后的粘合性能均较好 ,粘合性能保持率较高 。
The effects of various organocobalt salts and their levels on the adhesion strength between rubber and steel cord in TBR tire belt were investigated.The results showed that the initial adhesion strengthes of rubber compounds with any cobalt salt,such as cobalt stearate,cobalt boracyl and cobalt neodecanoate,were higher;the adhesion property of aged rubber compound with cobalt stearate was poorer;the adhesion property of cobalt neodecanoate compound was somewhat better than those of other two compounds;and the optimal level of cobalt neodecanoate was 0.58～0.81 phr.The adhesion properties of rubber compound with resorcinol/formaldehyde/silica/cobalt salt adhesion system before and after aging were better,the adhesion retention was higher,and the physical properties and the dynamic adhesion property to steel cord were better when compared to the original rubber compound in production.
