| 本文首先选取市场上国内和国外两种品牌、同型号的全钢子午线(TBR)轮胎,以扫描电子显微镜(SEM)为主要测试手段,从微观上对带束层胶料的早期损坏原因进行了分析,根据分析结果考察了普通氧化锌(ZnO)和活性氧化锌对带束层胶料基本力学性能及高温疲劳性能的影响。结果发现：胶料中残留的微米级ZnO颗粒是引发国内品牌轮胎带束层胶料早期损坏的主要原因之一。活性ZnO在橡胶基体中达到纳米级分散,分散均匀性高,胶料的基本力学性能和耐高温疲劳性能明显优于添加普通ZnO的胶料。 |
| 英文摘要: |
| Two kinds of all steel radial tires (TBR), with the same model, were selected from domestic and foreign brands respectively in this paper. And then the reasons for the initial damage of the tire belt compounds were investigated from the micro level by using scanning electron microscope (SEM). Furthermore, the effects of common ZnO and activated ZnO on the mechanical and high-temperature fatigue properties were discussed according to the results of SEM analysis. The results showed that theSmicroscaleSZnO remained in the compounds was the main cause to initiate the early damage of TBR belt vulcanizates for the domestic tires. The activated ZnO can be dispersed with nanoscale and high uniformity in rubber matrix, and then its mechanical and high-temperature fatigue properties were obviously superior to that of common ZnO. |
