中文摘要:
      研究硫化体系、助交联剂Si69用量、炭黑品种及其用量对NR硫化胶弹性的影响。结果表明，采用半有效硫化体系，硫化胶的弹性最好；硫化胶弹性随交联密度的增大而提高；随着炭黑粒径的减小或炭黑N330和N550用量的增大，硫化胶的邵尔A型硬度、拉伸强度和300%定伸应力增大，回弹值减小。以最小二乘法拟合出回弹值（y）与邵尔A型硬度（x1）和300%定伸应力（x2）之间的关系式分别为1/y=0.026 503 6+0.000 0125 3/(x1)，1/y=0.064 827+0.000 939 7/(x2)。
英文摘要:
      The effect of curative，level of cocuring agent Si69，and type and level of carbon black on elasticity of NR vulcanizate was investigated.The results showed that the optimum elasticity of vulcanizate was obtained by using semi-efficient curing system；the elasticity of vulcanized raised as the crosslinking density increased；Shore A hardness，tensile strength and modulus at 300% increased，and resilience lowered，as the particle size of carbon black reduced and the level of N330 and N550 increased.A relationship of resilience (y) to Shore A hardness (x1) and modulus at 300% (x2) was obtained by least-square fitting：1/y=0.026 503 6+0.000 012 53/(x1)；1/y=0.064 827+0.000 939 7/(x2).
