摘　　要：研究超锌活性剂AK-1在全钢载重子午线轮胎胎面胶中的应用,分别在白炭黑/炭黑并用及纯炭黑胶料中加入超锌活性剂AK-1等量替代间接法氧化锌。结果表明:与间接法氧化锌胶料相比,超锌活性剂AK-1胶料的焦烧时间延长,加工安全性提高;硫化胶的定伸应力和拉伸强度相当;白炭黑胶料的Payne效应减弱,填料的分散性更好,生热性能相当;试验轮胎的耐久性能满足标准要求;轮胎生产成本降低,且有利于轮胎轻量化。In this study,the application of super zinc activator AK-1 in the tread compound of all-steel truck and bus radial tire was investigated by replacing the indirect zinc with the same amount of super zinc activator AK-1 in the silica/carbon black jointly filled compound and carbon black filled compound,respectively.The results showed that,compared with the compound with indirect zinc oxide,the scorch time of the compound with super zinc activator AK-1 was prolonged and the processing safety was improved,the modulus and tensile strength of the vulcanizates were equivalent.The Payne effect of the compound containing silica decreased,indicating improved filler dispersion,and the heat build-up was equivalent.The durability of the test tire met the standard requirements.Moreover,the tire weight could be reduced and the tire production cost was lowered.
