超锌活性剂AK-1在半钢子午线轮胎气密层中的应用

Application of Super Zinc Activator AK-1 in Inner Liner of Steel-belted Radial Tire

研究超锌活性剂AK-1在半钢子午线轮胎气密层中的应用。结果表明:超锌活性剂AK-1用于半钢子午线轮胎气密层胶时具有优异的硫化活性和分散性;采用超锌活性剂AK-1等锌量替代氧化锌,胶料的硫化速率增大,硫化胶的硬度、撕裂强度、回弹值和耐屈挠性能变化不大,定伸应力和拉伸强度略有下降,气密性有所提高,满足气密层胶料的性能要求。

The application of super zinc activator AK-1 in the inner liner of steel-belted radial tire was studied.The results showed that super zinc activator AK-1 had excellent vulcanization activity and dispersion when being used in the inner liner compound of steel-belted radial tire.When the super zinc activator AK-1 was used to replace zinc oxide under the same zinc content,the vulcanization rate of the compound increased,the hardness,tear strength,resilience and flexural resistance of the vulcanizate changed little,the modulus and tensile strength decreased a little,and the air tightness was improved.The overall properties of the inner liner compound with AK-1 met the property requirements of the inner liner compound.
