纳米氧化锌在轮胎胶料中的应用研究

介绍了纳米氧化锌在轮胎胶料配方中的实际应用情况。由于纳米材料物有的小尺寸效应和表面效应，纳米氧化锌具有多功能性助剂的作用。应用研究表明，纳米氧化锌在基本不降低扯断伸长率的情况下，能明显提高胶料的300％定伸应力，且随材料比表面积的增大这种趋势愈加明显，胶料的磨耗量和压缩疲劳温升降低也更明显，另外，硫化曲线有整体随时间后移的倾向。纳米氧化锌减量50％使用可提高轮胎实际行驶里程约6.25%。

Application of nano-zinc oxide to tire compound

The application of nano zinc oxide to tire compound was described.The nano zinc oxide acted as a multi functional additive because of its small size effect and surface effect in nature.It was found by the application study that the modulus at 300% of compound increased and the abrasion loss and the temperature rise from compression fatigue decreased by adding nano zinc oxide,particularly nano zinc oxide with greater specific surface area.The cure curve also tended to shift backwards.The tread life of tire increased by 6.25% when the addition level of nano zinc oxide reduced by 50% compared to that of normal zinc oxide.
