【摘要】 研究了硫化温度和硫化时间对天然橡胶(NR)和NR/反式丁戊橡胶(TBIR)并用胶应用性能的影响。结果表明，在相同的硫化温度下，NR与NR/TBIR并用胶的焦烧时间、工艺正硫化时间和交联密度几乎一致。对比140℃、150℃和160℃硫化温度下NR和NR/TBIR硫化胶的性能，NR/TBIR并用胶在160℃下硫化时磨耗性能和滚动阻力优势最大，150℃硫化时疲劳性能优势最大。对比160℃下的硫化时间，发现其变化不会明显影响TBIR在NR体系中的磨耗性能、滚动阻力和疲劳性能优势的发挥。更多还原

【Abstract】 The effects of vulcanization temperature and time on the application properties of NR and NR/TBIR blends were studied.The results showed that, the scorch time, optimum curing time and crosslinking density of NR and NR/TBIR blends were almost the same at the same curing temperature.The properties of NR and NR/TBIR vulcanizated at 140 ℃,150 ℃ and 160 ℃ were investigated.Compared with NR vulcanizates, NR/TBIR vulcanized at 160 ℃ showed the greatest advantages in wear resistance and rolling resistance.And the fatigue resistance of NR/TBIR vulcanized at 150 ℃ was best.It was also found that the change of vulcanization time did not significantly affect the advantages of NR/TBIR vulcanizates in the wear resistance, rolling resistance and fatigue resistance compared with NR vulcanizates.更多还原
