| 中文摘要: |
| 采用微氧微纳再生胶（简称MOMN-RGTR）制备高抗撕裂MOMN-RGTR/天然橡胶（NR）/丁苯橡胶（SBR）实心轮胎胎冠胶，研究MOMN-RGTR的微观形貌、环保性能以及MOMN-RGTR用量对胎冠胶性能的影响。结果表明：MOMN-RGTR符合相关环保法规要求；填充MOMN-RGTR的胶料的门尼粘度小于填充普通轮胎再生胶（TRR）的胶料，加工性能改善；填充MOMN-RGTR的胶料的硫化速率提高；随着MOMN-RGTR填充量的增大，胶料的拉伸性能略有下降，但MOMN-RGTR填充量小于50份时，胶料各项指标均能满足实心轮胎胎冠胶的性能要求；填充MOMN-RGTR可大幅提高胶料的抗撕裂性能和耐磨性能，MOMN-RGTR填充量为50份时，胶料的撕裂强度最高（94 kN·m-1），阿克隆磨耗体积最小（0.317 cm3）；填充10份MOMN-RGTR的胶料的团聚程度小于添加10份TRR的胶料；填充20～50份MOMN-RGTR的胶料表面较平滑，团聚较少或无团聚现象，随着MOMN-RGTR填充量的继续增大，团聚现象增加。 |
| 英文摘要: |
| Micro-oxygen micro-nano reclaimed ground tire rubber（MOMN-RGTR）/natural rubber （NR）/styrene butadiene rubber（SBR） solid tire crown compound with high tear resistance was prepared，the microstructure，environmental performance of MOMN-RGTR，and the effect of MOMN-RGTR dosage on the properties of the crown compound were studied. The results showed that MOMN-RGTR met the requirements of relevant environmental regulations.The Mooney viscosity of the compound with MOMN-RGTR was lower than that of the compound with ordinary tire reclaimed rubber（TRR），and the processability was improved.The addition of MOMN-RGTR could improve the vulcanization rate of compound.As the dosage of MOMN-RGTR increased，the tensile properties of the compound slightly decreased，however，when the MOMN-RGTR dosage was less than 50 phr，all indicators met the requirements of solid tire crown compound. The addition of MOMN-RGTR could significantly improve the tear resistance and wear resistance of the compound. When the daosge of MOMN-RGTR was 50 phr，the tear strength was the highest（94 kN·m-1） and the Akron abrasion volume was the smallest（0.317 cm3）.The agglomeration degree of the compound with MOMN-RGTR was lower than that of the compound with TRR of the same dosage of 10 phr.The surface of the compounds with 20～50 phr MOMN-RGTR were relatively smoother，with little or no agglomeration.With the increase of MOMN-RGTR dosage，the agglomeration phenomenon of the compound increased. |
