摘　　要：对比研究白炭黑和新型补强剂Le用量对丁腈橡胶(NBR)胶料硫化特性和物理性能的影响,并对补强剂Le填充NBR胶料的动态力学性能、耐溶剂性能和微观结构进行研究。结果表明:白炭黑对NBR的补强效果好,但对胶料的加工性能产生不利影响;新型补强剂Le粒径较大、分散性较差,对NBR的补强效果不如白炭黑,但是可以改善胶料的加工性能,提高耐溶剂性能和降低成本。The effects of the addition levels of silica and new reinforcing agent Le on the curing behavior and physical properties of NBR compound were investigated,and the dynamic property,solvent resistance and microstructure of reinforcing agent Le filled NBR compound were studied. The results showed that,the reinforcement effect of silica to NBR was good,but it resulted in unfavorable effect on the processibility of compound.The size of new reinforcing agent Le was larger and the dispersion was worse,so its reinforcement effect was not as good as silica;but it could improve the processibility of compound,and could improve solvent resistance and reduce cost.
