| 中文摘要: |
| 考查多功能助剂DL-268用于轮胎缓冲层胶和外层帘布胶中对胶料与帘线之间粘合等性能的影响。结果表明，在硫黄硫化体系NR胶料中添加DL-268对硫化胶的综合物理性能无不良影响；随着DL-268用量的增大，胶料的ts2和t90略有延迟，胶料-帘线粘合性能得到改善，热老化后胶料-帘线粘合性能保持较佳；当DL-268用量为2份时，胶料综合性能较好。DL-268用于轮胎帘布胶中可提高成品轮胎的粘合性能，有益于克服轮胎脱层等缺陷。 |
| 英文摘要: |
| The effect of the multi-functional agent DL-268 on the adhesion between rubber compound and cord in breaker ply and carcass ply was investigated.The results showed that as the addition level of DL-268 increased up to 2 phr in sulfur cured NR compound of breaker ply and carcass ply，ts2 and t90 of rubber compound delayed a little，and the adhesion between rubber and cord，especially the adhesion retension after thermal aging improved without any adverse effect on the comprehensive physical properties of vulcanizate.The adhesion of finished tire improved and the separation was eliminated by adding DL-268 in breaker ply and carcass ply compounds. |
