新型结构空心球纳米活性氧化锌在全钢载重子午线轮胎胎侧胶中的应用

Application of New Hollow Spherical Nano-activated Zinc Oxide in Sidewall Compound of All-steel Truck and Bus Radial Tire

研究新型结构空心球纳米活性氧化锌在全钢载重子午线轮胎胎侧胶中的应用。结果表明:在胎侧胶中以2份新型结构空心球纳米活性氧化锌替代4份间接法氧化锌,胶料的门尼焦烧时间延长,硫化速度加快;硫化胶的拉伸强度和撕裂强度增大,压缩生热降低,耐热老化性能提高;成品轮胎的耐久性能达到国家标准要求。

The application of new hollow spherical nano-activated zinc oxide in the sidewall compound of all-steel truck and bus radial tire was investigated.In the sidewall compound formulation,2 phr new nanoactivated zinc oxide was applied to replace original 4 phr indirect zinc oxide.It was found that the Mooney scorch time of the compound was extended and curing speed was faster.The tensile strength and tearing strength of the vulcanizate increased,the compression heat build-up decreased and the thermal aging resistance was improved.The endurance performance of the finished tire met the requirements of national standards.
