| 中文摘要: |
| 研究配方因素对天然橡胶耐动态臭氧性能的影响。结果表明：所选硫化体系对胶料耐动态臭氧性能无影响；在保证胶料硬度相同的条件下，胶料耐动态臭氧性能随炭黑粒径的减小呈现出提高趋势；采用防老剂RD/4010NA并用体系的胶料耐动态臭氧性能最好；防老剂4010NA用量不影响胶料出现臭氧龟裂的初始时间；随着微晶蜡用量的增大，胶料耐动态臭氧性能逐渐提高。 |
| 英文摘要: |
| The effects of formulation factors on the dynamic ozone resistance of natural rubber were studied.The results showed that，with different curing systems selected in this study，the dynamic ozone resistance of the compounds was similar.With the decrease of the carbon black particle size，the dynamic ozone resistance of the compound with the same hardness showed a tendency to increase.The dynamic ozone resistance of the compound with antioxidant RD/4010NA was the best among the studied antioxidant packages.The addition level of antioxidant 4010NA did not affect the initial cracking time of the compound.The dynamic ozone resistance gradually increased with increasing the addition level of microcrystalline wax. |
