%X 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，t<sub>90</sub>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。;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，t<sub>90</sub> 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
