中文摘要: |
研究了普通硫化体系(CV)、半有效硫化体系(SEV)和有效硫化体系(EV)对NR/BR/TPI共混物(共混比为40/40/20)性能的影响,特别是CV体系中硫黄和促进剂DM用量的影响。结果表明,采用CV体系,NR/BR/TPI共混物的耐疲劳性能等物理性能较好,硫黄用量为3份、促进剂DM用量为1份时,共混物的撕裂强度和耐屈挠性能最好,其它性能也保持在较高水平。配合剂直接加入共混胶中混炼比分别加入3种生胶混炼后再加以混合的方式可获得更好的力学性能,但正硫化时间和焦烧时间缩短。 |

The effects of the conventional vulcanization(CV),semi-efficient vulcanization(SEV),efficient vulcanization(EV),especially the levels of sulfur and accelerator DM on the properties of NR/BR/TPI(40/40/20) blend were investigated.The results showed that the better fatigue property of the blend was obtained by using CV system,and the best tear strength and flexibility of the blend were obtained by using 3 phr of sulfur and 1 phr of DM without affecting the other properties. |
