摘要
研究了不同牌号的炭黑对天然橡胶(NR)钢丝复合体综合性能的影响,并选取了应用最为广泛的炭黑N330对复合体的填料添加量进行优化分析。结果表明,炭黑N550填充NR胶料的焦烧时间与正硫化时间最长,炭黑N115填充NR胶料的交联密度最大,炭黑N330填充NR胶料的综合物理机械性能最佳,含有N375的橡胶钢丝复合体的黏合性能最佳;随着N330添加量的增加,复合体硫化特性明显提升,物理机械性能与复合体黏合性能均呈现先增加后减小趋势。
The effect of different grades of carbon black on the comprehensive performance of natural rubber steel wire composites was studied,and the most widely used carbon black N330 was used to optimize the analysis of the amount of fillers in the composites.The results show that the carbon black N550 filled NR compound has the longest scorch time and positive vulcanization time,and the carbon black N115 filled NR compound has the largest crosslink density,and the carbon black N330 filled NR compound has the best physical and mechanical properties,and the performance of the composite containing N375 is the best;as the amount of filler added was increased,the vulcanization characteristics of the composite have been significantly improved,and the physical and mechanical properties and the bonding performance of the composite both show a trend of increasing first and then decreasing.
