摘要:
将炭黑(CB)、氢氧化单甲基丙烯酸锌(HZMMA)和碳纳米管(CNTs)进行复配,以改性氢化丁腈橡胶(HNBR)/氟橡胶(FKM)共混胶,制备了HNBR/FKM复合材料,研究了复合型增强剂对HNBR/FKM共混胶硫化特性、硫化胶的物理机械性能、动态力学性能和耐热氧老化性能的影响。结果表明,当加入HZMMA和CNTs后,HNBR/FKM复合材料的硫化速率加快且交联程度提高;在HZMMA和CNTs的协同作用下,HNBR/FKM复合材料的物理机械性能明显提高;与纯CB增强的相比,加入3份(质量)CNTs的HZMMA增强的HNBR/FKM复合材料热氧老化后扯断伸长率的保持率最高,与此同时硬度变化率最低;随着CNTs添加量的增加,HNBR/FKM复合材料的玻璃化转变温度向低温方向移动,同时损耗因子呈逐渐下降的趋势。
Abstract:
HNBR/FKM composites were prepared by compounding carbon black (CB), hydroxide zinc monomethacrylate (HZMMA) and carbon nanotubes (CNTs) to modify hydrogenated nitrile rubber (HNBR)/ fluororubber (FKM) blend, and the effects of the composite reinforcing agent on the curing characteristics of HNBR/FKM blends, and the physico-mechanical properties, dynamic mechanical properties and thermal-oxydative aging properties of the vulcanized rubber were investigated. The results showed that the curing rate of HNBR/FKM compo-sites was accelerated and the cross-linking degree was increased when HZMMA and CNTs were added, and the physico-mechanical properties of HNBR/FKM composites were significantly improved under the synergistic effect of HZMMA and CNTs. HNBR/FKM composites reinforced by HZMMA and CNTs of 3 phr (mass) exhibited the highest retention rate of elongation at break and the lowest change rate of hardness after thermal-oxydative aging compared with that reinforced by pure CB. As the addition amount of CNTs increased, the glass transition temperature of HNBR/FKM composites moved towards the lower temperature and the loss factor decreased gradually.
