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。The application of super zinc activator AK-1 in the bead compound of tires was studied.The results showed that,by using super zinc activator AK-1 to replace the indirect zinc oxide with equal amount or equal zinc content,the scorch time of the bead compound was shortened,the crosslinking density of the vulcanizate increased,the modulus increased,the tensile strength was equivalent,and the heat aging property of the vulcanizate was improved.Moreover,the Payne effect of the compound decreased,the dispersion of fillers was improved,while the hysteresis loss and heat build-up of the vulcanizates were reduced.In addition,the application of super zinc activator AK-1 could reduce the zinc content in the compound,which had the advantages of low cost and good environmental protection.
