中文摘要: |
研究炭黑/煤矸石/碳纳米管(CNTs)复合填料体系对天然橡胶(NR)性能的影响。结果表明:CNTs延迟硫化效应明显;相比炭黑,煤矸石对硫化具有促进作用;在填料用量相同的条件下,单独由炭黑填充的NR有最大的交联密度,CNTs对交联密度影响不明显;当煤矸石/炭黑/CNTs用量比为17.5/16.5/1时,复合填料填充NR具有良好的综合性能。 |
英文摘要: |
The influence of modified carbon black(CB)/coal gangue(CG)/carbon nanotubes(CNTs) on the properties of NR was investigated.The results showed that,compared with CB,CNTs delayed vulcanization and CG accelerated it.At same total addition level of filler,the crosslink density of NR composite filled with only CB was the highest,and CNTs had no significant effect on crosslink density.The NR filled with hybrid fillers possessed good comprehensive properties when blending ratio of CG/CB/CNTs was 17.5/16.5/1. |
