中文摘要:
      研究硅酸钙/炭黑并用比对天然橡胶(NR)再生胶性能的影响。结果表明:随着硅酸钙/炭黑并用比的增大,NR再生胶的焦烧时间逐步缩短,操作安全性降低,t90逐步缩短,硫化速率逐步提高;密度、邵尔A型硬度和拉断永久变形变化不大,拉伸强度和拉断伸长率明显提高,即硅酸钙对NR再生胶有明显的补强作用。
英文摘要:
      The effect of calcium silicate/carbon black blend ratio on the properties of NR reclaim was investigated.The results showed that,as calcium silicate/carbon black blend ratio increasing,the scorch time of NR reclaim was gradually shortened,indicating reduced processing safety,t90 was gradually shortened,the vulcanization rate gradually increased,the density,Shore A hardness and tensile set at break changed a little,and the tensile strength and elongation at break increased significantly.The study showed that calcium silicate had a good reinforcement effect on NR reclaim.
