【摘要】 通过还原剂、强酸及添加金属化合物的方法处理３种粘土，并制备相应的粘土填充ＮＲ硫化胶（简称粘土填充胶）进行热氧老化性能测试。结果表明：粘土中的铜、锰、钴、铁４种金属组分对粘土填充胶老化性能产生影响，其中以钴最为显著，其次是铜，最后是铁和锰。在一定范围内，铁含量变化对粘土填充胶老化未产生明显作用。由于金属组分在粘土中存在形式的差异，粘土填充胶的老化性能与粘土中有害金属含量不存在对应关系更多还原

【Abstract】 The thermaloxydative aging properties were determined on the NR vulcanizates filled with 3 types of clays which were treated by reductant and strong acid and different metal compounds were added in.The results showed that the aging properties of clayfilled vulcanizates were influenced by the metal components in clay in order of Co>Cu>Fe>Mn;the change of iron content in a certain range did not have significant effect on the aging properties of clayfilled vulcanizate;and the aging properties of clayfilled vulcanizate were not in correspondence with the content of harmful metals in clay because the metal components in clay existed in different forms.更多还原
