中文摘要:
      选用芳纶短切纤维(DCF)和芳纶浆粕(PPTA)2种芳纶短纤维分别补强炭黑N220填充、过氧化物硫化的氢化丁腈(HNBR)胶料,力求制备出高强度、高模量的HNBR复合材料,比较了芳纶短纤维的类型和用量对氢化丁腈胶料性能的影响。实验结果表明,随着DCF用量的增加,HNBR/CB体系的门尼黏度增加,但PPTA对HNBR/CB体系的门尼黏度几乎没有影响;芳纶短切纤维DCF填充的HNBR/CB体系比芳纶浆粕PPTA填充的HNBR/CB体系具有更明显的填料网络;DCF填充的HNBR/CB体系具有更高的硬度、拉伸强度以及撕裂强度。
英文摘要:
      Aramid discontinue fiber (DCF) and aramid pulp (PPTA) were used to reinforce peroxide-cured hydrogenated acrylonitrile butadiene rubber (HNBR) filled with carbon black (N220) to obtain HNBR composites with high modulus and strength. The effects of type and dosage of fibers on the mechanical properties were studied. The results show the Mooney viscosity of HNBR/CB composites increases with increase of the content of DCF, but the dosage of PPTA has little effect on the Mooney viscosity of HNBR/CB composites. HNBR/CB/DCF vulcanizates show stronger filler-filler networks than HNBR/CB/PPTA vulcanizates. The strength and hardness of HNBR/CB/DCF vulcanizates are higher than those of HNBR/CB/PPTA vulcanizates.
