氯丁橡胶-黄铜粘合界面微量元素含量对 粘合力的影响

对填充不同炭黑品种氯丁橡胶（CR）（硫化胶）-黄铜粘合界面微量元素含量与粘合力的关系进行分析，研究老化前、热老化后和水浸泡后CR-黄铜粘合界面微量元素含量的变化，以及化学粘合和物理粘合时CR-黄铜粘合界面微量元素含量对粘合力的影响。结果表明：化学粘合时，热老化后CR-黄铜粘合界面的S元素质量分数、Cu元素质量分数和S元素/Cu元素质量分数比增大，粘合力增大；水浸泡后CR-黄铜粘合界面的S元素质量分数减小，Cu元素质量分数增大，粘合力减小；物理粘合时，热老化后和水浸泡后CR-黄铜粘合界面的微量元素质量分数变化不大，其微量元素质量分数不能表征粘合力大小。;The relationship between trace element content in the bonding interface of chloroprene rubber （CR）（vulcanizate） filled with different carbon black varieties-brass and adhesion was analyzed.The changes of trace element content in the CR-brass bonding interface before aging，after thermal aging and after water immersion were investigated，and the effects of trace element content in the CR-brass bonding interface by chemical bonding and physical bonding on adhesion were studied.The results showed that，after thermal aging，the S element mass fraction，Cu element mass fraction and S element/Cu element mass fraction ratio of CR-brass bonding interface by chemical bonding increased，and the adhesion increased.After water immersion，the S element mass fraction of CR-brass bonding interface by chemical bonding was decreased，the Cu element mass fraction increased，and the adhesion decreased.After thermal aging and water immersion，the trace elements mass fraction of CR-brass bonding interface by physical bonding had little change，and the trace elements mass fraction could not be used to characterize the adhesion strength
