| 中文摘要: |
| 研究超锌活性剂AK-1在轮胎胎圈护胶中的应用。结果表明：用超锌活性剂AK-1等量或等锌量替代间接法氧化锌，胶料的焦烧时间缩短，交联密度增大；硫化胶的定伸应力增大，拉伸强度相当，耐热老化性能提高；胶料的Payne效应减弱、填料分散性改善，硫化胶的滞后损失降低，生热低。添加超锌活性剂AK-1可降低胶料配方中锌含量，具有成本和环保优势。 |
| 英文摘要: |
| Application of super zinc activator AK-1 in bead compound of tire was studied.The results showed that，using AK-1 with equal amount or equal zinc content instead of indirect zinc oxide，the scorch time of compound was shortened and the crosslinking density was higher.The modulus increased，the tensile strength was equivalent，the heat aging property of the vulcanizate was improved.The Payne effect of compound decreased，the hysteresis loss and heat build up of vulcanizate was reduced.In addition，the addition of super-zinc activator AK-1 could reduce the zinc content in the rubber compound，which had the advantage of cost and environmental protection. |
