摘　　要：主要研究了3种改性纳米碳酸钙(CCR、M CCR、M CaCO3)对丁腈胶力学性能的影响。NBR/M CaCO3硫化胶的力学性能优于NBR/CCR和NBR/M CCR体系,交联密度测定和丙酮抽出实验的结果表明,M CaCO3参与了橡胶的共硫化,提高了硫化胶的交联密度。The mechanical properties of NBR vulcanizates filled with three kinds of modified nano-calcium carbonate,M-CaCO_3,M-CCR and CCR were studied.The results showed that the mechanical properties of NBR/M-CaCO_3　system are superior to those of NBR/M-CCR and NBR/CCR systems.The crosslinking density determination and the extraction ratio experiment showed that M-CaCO_3 takes part in co-vulcanization with rubber,so that the crosslinking density is increased.
