| 中文摘要: |
| 研究硫黄、促进剂CBS和防焦剂CTP预分散母胶粒（牌号分别为S-80，CBS-80和CTP-80，有效成分质量分数均为0.8）门尼粘度和活性成分粒径对其在天然橡胶中分散均匀性的影响。结果表明：低门尼粘度配合剂预分散母胶粒的分散性较好；混炼胶门尼粘度较低时，高门尼粘度配合剂预分散母胶粒分散性较差；增大混炼程度可提高配合剂预分散母胶粒在胶料中的分散性，但无法彻底消除活性成分粒径对配合剂母胶粒分散性的影响。 |
| 英文摘要: |
| In this study，the influence of the Mooney viscosity and active ingredient particle size of the additive pre-dispersed masterbatch，for example，sulfur，accelerator CBS and anti-scorching agent CTP pre-dispersed masterbatch which were referred to as S-80，CBS-80 and CTP-80 and all had effective additive content of 0. 8，on the dispersion of the additive pre-dispersed materbatch in the natural rubber（NR） compound was investigated. The results showed that the dispersion of the additive pre-dispersed masterbatch with lower Mooney viscosity was better. When the Mooney viscosity of the NR compound was low，the dispersion of the additive pre-dispersed materbatch with higher Mooney viscosity was poor. The dispersion of the additive pre-dispersed materbatch could be improved by increase of mixing intensity；however，the effect of the particle size of active ingredient could not be completely eliminated. |
