氧化锌RA和NC-05在载重轮胎胎面胶中的应用

Application of Zinc Oxide RA and NC-05 in Tread Compound of Truck Tire

研究氧化锌RA和NC-105在载重轮胎胎面胶中的应用。结果表明:氧化锌RA等量替代普通氧化锌(氧化锌质量分数为0.997),胎面胶的压缩生热略有降低,成品轮胎的耐久性能和高速性能相当;氧化锌NC-105减量替代普通氧化锌,胎面胶的工艺性能改善,耐磨性能和耐热老化性能提高,压缩生热降低,成品轮胎的耐久性能和高速性能提高。氧化锌RA和NC-105替代普通氧化锌可以有效减小胎面胶的重金属和锌含量,降低轮胎生产成本。

The application of zinc oxide RA and NC-105 in tread compound of truck tire was studied. The results showed that by using zinc oxide RA to replace an equal amount of regular zinc oxide （ mass fraction 0. 997）, the compression heat build-up of the tread compound was slightly lower, and the durability and high-speed performance of the finished tire were the same. By using less amount of zinc oxide NC- 105 to replace regular zinc oxide, the processing properties of the tread compound were improved, wear resistance and heat aging resistance were improved, the compression heat build-up was reduced, and the durability and high-speed performance of the finished tire were improved. With zinc oxide RA and NC-105 replacing regular zinc oxide in the tread compound, the heavy metal content and zinc content were effectively reduced, and the tire production cost was also reduced.
