| 中文摘要: |
| 研究有机过氧化物DCP/硫黄并用硫化体系在轮胎胎侧胶中的应用。结果表明：与硫黄硫化的胶料相比，有机过氧化物DCP/硫黄并用硫化体系硫化的胶料的门尼焦烧时间缩短，硫化速度减慢，但Fmax增大，抗硫化返原性提高；硫化胶的硬度、定伸应力、拉伸强度和撕裂强度增大，耐热老化性能和耐臭氧老化性能提高，耐屈挠性能相当。 |
| 英文摘要: |
| The application of organic peroxide DCP/sulfur curing system in the sidewall compound of tire was studied.The results showed that compared with sulfur vulcanized compound，the Mooney scorch time of the compound vulcanized with organic peroxide DCP/sulfur curing system was shortened，the curing speed was slowed down，but the Fmax was increased，and the anti-reversion property was improved.The hardness，modulus，tensile strength and tear strength of the vulcanizate were increased，the heat aging resistance and ozone aging resistance were improved，and the flexure resistance was equivalent. |
